Description

COMPOSITIONS COMPRISING MELT-PROCESSED INORGANIC FIBERS AND METHODS OF USING SUCH COMPOSITIONS
BACKGROUND
The present invention relates to subterranean well cementing operations, and more particularly, to cement compositions comprising melt-processed inorganic fibers and methods for using such cement compositions.
Hydraulic cement compositions commonly are utilized in subterranean operations, particularly subterranean well completion and remedial operations. For example, hydraulic cement compositions are used in primary cementing operations whereby pipe strings, such as casing and liners, are cemented in well bores. In performing primary cementing operations, usually a hydraulic cement composition is pumped into an annular space between the walls of a well bore and the exterior surface of the pipe string disposed therein. The cement composition sets in the annular space, forming therein an annular sheath of hardened, substantially impermeable cement that supports and positions the pipe string in the well bore and bonds the exterior surface of the pipe string to the walls of the well bore. Hydraulic cement compositions also are used in remedial cementing operations, such as plugging highly permeable zones or fractures in well bores, plugging cracks and holes in pipe strings, and the like.
When the cement compositions contact permeable subterranean formations, fluid (e.g., water) may be lost into the formation. Excessive fluid loss may cause the cement composition to become prematurely dehydrated, thereby potentially causing bridging in the annulus and limiting the time for which said slurry can remain pumpable, and/or reducing bond strength between the set cement composition and a subterranean zone, the walls of pipe and/or the walls of the well bore. Fluid loss control additives (e.g., polymers and copolymers) may be included in a cement composition, inter alia, to reduce fluid loss into the formation. When the permeability of the formation is high, for example, because of unconsolidated or depleted formations, or microfractures, the rate of fluid loss may increase to an extent that some conventional fluid loss control additives (e.g., polymer and copolymers) may not be effective in preventing fluid loss from cement compositions. In an extreme case, fluid loss may increase to the point where the cement composition no longer can be circulated back to the surface — in such case, the cementing operation being conducted may be said to have "lost circulation." To help control fluid loss, and to prevent fluid loss from escalating to "lost circulation," certain types of fluid loss control additives that sometimes are referred to as "lost circulation materials" may be included in cement compositions. Examples of conventional lost circulation materials include peanut shells, mica, cellophane, walnut shells, calcium carbonate, plant fibers, cottonseed hulls, ground rubber, and polymeric materials.
Lost circulation also can occur during drilling of subterranean well bores. For example, fluid may be lost into high-permeability zones (e.g., unconsolidated zones or depleted formations), vugular zones, and fractures (e.g., either pre-existing fractures or fractures created during the subterranean operation). Conventional attempts to prevent lost circulation during subterranean drilling operations have involved, for example, the addition of soluble additives (e.g., polymers) to drilling fluids. However, when circulation losses exceed 1 barrel per hour, these additives may not be as effective as desired.
In many cases when circulation losses have been encountered that exceed 1 barrel per hour, conventional insoluble particulate materials (e.g., fibers) have been added to the drilling fluid. Such conventional insoluble particulate materials may form a filter cake on the walls of the well bore. This filter cake may be less permeable than the well bore walls, and, accordingly the establishment of the filter cake may reduce circulation losses. However, the use of conventional insoluble particulate materials may be problematic. For example, if the conventional particulate materials are not chosen carefully, they may cause pumping problems or plug flow lines. In some circumstances, the conventional particulate materials may be screened out on shale shakers (and thus be prevented from remaining with the circulating fluid as it flows into the well bore). In some cases, the comparatively lighter density of the conventional particulate materials may cause them to tend to remain afloat within the comparatively denser drilling fluid. In other circumstances, the addition of conventional particulate materials may cause the drilling fluid to become excessively thick and viscous.

The present invention relates to subterranean well cementing operations, and more particularly, to cement compositions comprising melt-processed inorganic fibers and methods for using such cement compositions.
Certain embodiments of the cement compositions of the present invention comprise a hydraulic cement, water, and a plurality of melt-processed inorganic fibers having a mean aspect ratio of greater than about 25, a specific gravity of greater than about 1.2, and a length of less than about 10 millimeters. As referred to herein, the term "aspect ratio" will be understood to mean the ratio of a solid body's length to its width. As referred to herein, the term "melt-processed inorganic fibers" will be understood to mean fibers produced from inorganic materials using any suitable melt processing technique, such as melt blowing or melt spinning.
Any hydraulic cement suitable for use in subterranean cementing operations may be used in accordance with the present invention. A variety of hydraulic cements are suitable for use, including those comprising calcium, aluminum, silicon, oxygen, and/or sulfur, which set and harden by reaction with water. Such hydraulic cements include, but are not limited to, Portland cements, pozzolanic cements, gypsum cements, soil cements, calcium phosphate cements, high alumina content cements, silica cements, high alkalinity cements, and mixtures thereof. In certain embodiments, the cement compositions of the present invention may comprise a Portland cement. In certain embodiments, the Portland cement may be chosen from those classified as Class A, C, G, and H cements according to API Specification for Materials and Testing for Well Cements, API Specification 10, Fifth Ed., My I, 1990. Another cement that may be useful in certain embodiments of the present invention is commercially available under the trade name "THERMALOCK™" from Halliburton Energy Services, Inc., of Duncan, OK. Other cements that may be suitable for use in accordance with the present invention include, inter alia, low-density cements. Such low-density cements may be, inter alia, foamed cements or cements comprising another means to reduce their density, such as hollow microspheres, low-density elastic beads, fly ashes, blast furnace slag, or other density-reducing additives known in the art.
Generally, the water utilized in the cement compositions of the present invention may be fresh water, salt water {e.g., water containing one or more salts dissolved therein), brine (e.g., saturated salt water), seawater, or any combination thereof. This water may be from any source, provided that the water does not contain an excess of compounds (e.g., dissolved organics) that may adversely affect other components in the cement composition. In some embodiments, the water may be present in the cement compositions of the present invention in an amount sufficient to form a pumpable slurry. In certain embodiments, the water is present in the cement compositions of the present invention in an amount in the range of from about 30% to about 180% by weight of cement ("bwoc") therein. In certain embodiments, the water is present in the cement compositions of the present invention in an amount in the range of from about 40% to about 50% bwoc therein. One of ordinary skill in the art, with the benefit of this disclosure, will recognize the appropriate amount of water for a chosen application.
The cement compositions of the present invention comprise melt-processed inorganic fibers. Among other things, inclusion of melt-processed inorganic fibers in the cement compositions of the present invention may aid in the prevention of lost circulation and/or enhance the compressive and tensile strengths of the set cement composition. Inclusion of melt-processed inorganic fibers in the cement compositions of the present invention may be particularly appropriate when fluid loss of about 1 barrel per hour, or more, is encountered.
Melt processing is a well-known procedure for the production of fibers. Suitable melt processing techniques are described in Encyclopedia of Polymer Science and Engineering: Fiber Manufacture, J.E. Mcintyre and MJ. Denton (J.I. Kroschwitz ed., John Wiley and Sons 2d ed.). Suitable examples of melt-processed fibers include melt-blown fibers and melt-spun fibers. In some embodiments, combinations of melt-blown and melt-spun fibers may be used. The melt spinning of fibers may include spinning the material into a continuous strand of single or multiple filaments and then cutting it into a desired length.
The melt-processed inorganic fibers suitable for use in the methods and compositions of the present invention generally have a mean length of less than about 10 millimeters. In certain embodiments, the melt-processed inorganic fibers may have a mean length in the range of from about 0.1 millimeters to about 10 millimeters. In certain embodiments, the melt-processed inorganic fibers may have a mean length of about 0.5 millimeters, or about 1 millimeter, or about 2 millimeters, or about 3 millimeters, or about 4 millimeters, or about 5 millimeters, or about 6 millimeters, or about 7 millimeters, or about 8 millimeters, or about 9 millimeters, or about 10 millimeters. The melt-processed inorganic fibers suitable for use in the methods and compositions of the present invention generally have a mean aspect ratio of greater than about 25. In certain embodiments, the melt-processed inorganic fibers suitable for use in the methods and compositions of the present invention may have a mean aspect ratio of greater than about 100. In certain embodiments, the melt-processed inorganic fibers may have a mean aspect ratio in the range of from about 130 to about 660. In certain embodiments, the melt-processed inorganic fibers may have a mean aspect ratio in the range of from about 130 to about 330. In certain embodiments, the melt-processed inorganic fibers may have a mean aspect ratio in the range of from about 260 to about 660. The melt- processed inorganic fibers may be cut to any desired length, e.g., by mechanically cutting the fiber strands, so as to produce strands having a desired length. As will be appreciated by one of ordinary skill in the art, with the benefit of this disclosure, the length and diameter of the melt-processed inorganic fibers may be adjusted to enhance properties such as their flexibility and ease of dispersion in the cement compositions of the present invention.
The melt-processed inorganic fibers should be present in the cement compositions of the present invention in an amount sufficient to provide the desired mechanical properties and/or fluid loss control. In some embodiments, the melt-processed inorganic fibers may be present in the cement compositions of the present invention in an amount in the range of from about 0.1% to about 20% bwoc. In some embodiments, the melt-processed inorganic fibers may be present in an amount in the range of from about 0.1% to about 10% bwoc. In some embodiments, the melt-processed inorganic fibers may be present in the cement compositions of the present invention in an amount in the range of from about 0.1% to about 3% bwoc.
Suitable melt-processed inorganic fibers may be produced from a variety of materials. Examples of suitable inorganic fibers that may be melt-processed to form suitable melt- processed inorganic fibers include basalt fibers, wollastonite fibers, non-amorphous metallic fibers, ceramic fibers, glass fibers (e.g., AR glass fibers and non-AR glass fibers), and combinations thereof. Basalt fibers generally are produced from basalt, which is an igneous rock that is generally comprised of microscopic grains, such as calcium-sodium (plagioclase) feldspar, pyroxene, and olivine. Suitable melt-processed basalt fibers are commercially available from Sudaglass Fiber Technology, Houston, TX. Suitable melt-processed ceramic fibers may be processed from alumina-silica material. An example of suitable commercially available melt-processed ceramic fibers is "FIBERFRAX" ceramic fiber, available from Unifrax Corporation, Niagara Falls, NY.
As noted above, in certain embodiments of the present invention, the melt-processed inorganic fibers may comprise nonamorphous metallic fibers that have been melt-processed. In certain embodiments, the non-amorphous metallic fibers may be obtained by cold drawing low-carbon steel wires (e.g., steel wool). Suitable metallic fibers include, but are not limited to, chopped steel fibers, stainless steel fibers, brass fibers, bronze fibers, nickel fibers, and titanium fibers. In certain embodiments of the present invention, the non-amorphous metallic fibers are low-carbon chopped steel wool fibers. Examples of suitable metallic fibers include, inter alia, those that are commercially available from Global Material Technologies, of Palatine, Illinois, under the trade names "GMT-2136," "GMT-180," and "GMT-380." In certain embodiments wherein steel fibers are used, the steel fibers may comprise carbon present in an amount in the range of from about 0.06% to about 0.11% by weight. In certain embodiments of the present invention wherein the high aspect ratio material comprises non- amorphous metallic fibers, the non-amorphous metallic fibers generally have a mean diameter in the range of from about 0.025 millimeters to about 0.10 millimeters, and a mean length in the range of from about 0.1 millimeter to about 10 millimeters. As will be appreciated by one of ordinary skill in the art, with the benefit of this disclosure, the length and diameter of the non-amorphous metallic fibers may be adjusted to enhance properties such as their flexibility and ease of dispersion in the cement compositions of the present invention. In certain embodiments of the present invention wherein non-amorphous metallic fibers are included, the non-amorphous metallic fibers generally have an aspect ratio in the range of from about 1.25 to about 400. In certain embodiments, the non-amorphous metallic fibers may have an aspect ratio in the range of from about 15 to about 200, and in certain other embodiments, from about 25 to about 100. In certain embodiments of the present invention where non-amorphous metallic fibers are included, the metallic fibers may be present in the cement compositions of the present invention in an amount in the range of from about 0.5% to about 10% bwoc. Due to their density, certain metallic fibers may exhibit a propensity to settle out of the cement compositions of the present invention. Therefore, certain embodiments of the cement compositions of the present invention that comprise melt- processed non-amorphous metallic fibers also may comprise a settling-prevention additive, such as a viscosifier, that may eliminate, or at least reduce, settling. Suitable settling- prevention additives include, inter alia, hydroxyethylcellulose, and xanthan gum. A suitable settling-prevention additive is commercially available from Halliburton Energy Services, Inc., under the trade name "FWCA." Where settling-prevention additives are included in the cement composition, they should be present in the cement composition in an amount that facilitates a uniform density throughout the cement composition. In certain embodiments, non-amorphous metallic fibers may be coated by, e.g., surfactants that may inhibit any reaction that may occur between the cement composition and the metallic fibers. Examples of suitable surfactants that may be used to coat the non-amorphous metallic fibers include, inter alia, hydrophobic organic materials such as sorbitol mono-oleate, sorbitol tri-oleate, and the like. Sorbitol mono-oleate is commercially available from Aldrich Chemical Company, of Milwaukee, Wisconsin, under the trade name "SPAN 80," while sorbitol tri-oleate is commercially available from Aldrich Chemical Company under the trade name "SPAN 85." In certain embodiments of the present invention wherein the non-amorphous metallic fibers are coated, the coating may be present on the non-amorphous metallic fibers in an amount in the range of from about 0.5% to about 5% by weight of the fibers.
As noted above, in certain embodiments of the present invention, the melt-processed inorganic fibers may comprise glass fibers. In certain embodiments, the glass fibers are alkali-resistant (AR) glass fibers, although non-AR glass fibers also may be used in certain embodiments of the present invention. Examples of suitable non-AR glass fibers include general purpose E-glass fibers and specialty glass fibers, such as ECR glass fibers (high corrosion resistance), A-glass fibers, and C-glass fibers. These grades refer to ASTM Specification D 578-98. In certain embodiments of the present invention where non-AR glass fibers are used, the non-AR glass fibers may be made alkali-resistant through the application of a coating with an acrylic acid-based polymer, as will be understood by one of ordinary skill in the art, with the benefit of this disclosure. In certain embodiments wherein the cement compositions of the present invention comprise an alkaline cement, and the melt- processed inorganic fibers comprise glass fibers, AR glass fibers may be particularly suitable. However, when prepared using larger portions of pozzolanic or latent-hydraulic cement additives (e.g., coal, fly ash, or silica dust), or high aluminate cements, certain embodiments of the cement compositions of the present invention may have lower pH values, which may facilitate the use of non-AR glass fibers. One of ordinary skill in the art, with the benefit of this disclosure, will recognize the amounts and mixtures of AR and non-AR resistant glass fibers to use depending on the alkalinity of the cement being used. In certain embodiments, the AR glass fibers may comprise zirconium oxide in an amount in the range of from about 0.01% to about 15% by weight; in certain other embodiments, the AR glass fibers may comprise zirconium oxide in an amount in the range of from about 10% to about 15% by weight. In certain embodiments of the present invention, the glass fibers have a length in the range of from 0.5 to about 10 millimeters, and a diameter in the range of from about 10 to about 400 microns. In certain embodiments, the glass fibers may have an aspect ratio in the range of from about 1.25 to about 5,000. In certain embodiments, the glass fibers may have an aspect ratio in the range of from about 10 to about 1,000, and in certain other embodiments, from about 20 to about 500. Examples of suitable glass fibers include, inter alia, "CEM-FIL® HD" chopped strands and "CEM-FIL®HP" chopped strands, available from Saint-Gobain Vetrotex America, Inc., of Valley Forge, Pennsylvania. Other examples of suitable glass fibers include, inter alia, "E" grade "FIBERGLAST," available from Fiberglast Development Corp., of Brookville, Ohio. When included in the cement compositions of the present invention, the glass fibers may be present in an amount in the range of from about 0.1% to about 20% bwoc.
Optionally, the non-amorphous metallic fibers and the glass fibers described above may be added to the cement composition without having been melt-processed, as an additional component to the melt-processed inorganic fibers.
Optionally, certain embodiments of the cement compositions of the present invention also may include solid materials that may strengthen and reinforce the cement. These solid materials may include both natural and man-made materials, and may have any shape, including, but not limited to, beaded, cubic, bar-shaped, flake, fiber, platelets, cylindrical, or mixtures thereof. Suitable such solid materials include, but are not limited to, carbon fibers, plastic fibers {e.g., polypropylene and polyacrylic nitrile fibers), and combinations thereof. Where included, these additional solid materials may be added to the cement composition of the present invention individually or in combination. Additionally, the solid materials of the present invention may be present in the cement composition in a variety of lengths and aspect ratios. One of ordinary skill in the art, with the benefit of this disclosure, will recognize the mixtures of type, length, and aspect ratio to use to achieve the desired properties of a cement composition for a particular application.
Optionally, additional additives may be added to the cement compositions of the present invention as deemed appropriate by one skilled in the art with the benefit of this disclosure. Examples of such additives include, inter alia, fly ash, silica compounds, fluid loss control additives, lost circulation materials, a surfactant, a dispersant, an accelerator, a retarder, a salt, a formation conditioning agent, fumed silica, bentonite, microspheres, expanding additives, weighting materials, organic fibers, and the like. For example, the cement compositions of the present invention may be foamed cement compositions comprising an expanding additive that produces gas within the cement composition in order, inter alia, to reduce the cement composition's density. An example of a suitable expanding additive comprises a blend containing gypsum, and is commercially available under the trade name "MICROBOND" from Halliburton Energy Services, Inc., at various locations. One of ordinary skill in the art with the benefit of this disclosure will recognize the proper amount of an expanding additive to use in order to provide a foamed cement composition having a desired density. An example of a suitable sodium silicate is commercially available from Halliburton Energy Services, Inc., under the trade name ECONOLITE®. An example of a suitable additive that demonstrates free-water-reduction and solids-suspension properties is commercially available from Halliburton Energy Services, Inc., of Duncan, Oklahoma, under the trade name "FWC A™." An example of a suitable dispersant is commercially available from Halliburton Energy Services, Inc., under the trade name "CFR-3." An example of a suitable fly ash is an ASTM class F fly ash that is commercially available from Halliburton Energy Services, Inc., under the trade name "POZMIX® A." An example of a suitable silica flour is commercially available from Halliburton Energy Services, Inc., under the trade name "SSA-I."

An example of a suitable defoamer is commercially available from Halliburton Energy Services, Inc., under the trade name "D-AIR 3000L."
The melt-processed inorganic fibers may be added to the cement composition at any suitable time, such as before, after, or simultaneously with combining the water and the cement.
To facilitate a better understanding of the present invention, the following examples of certain aspects of some embodiments are given. In no way should the following examples be read to limit, or define, the scope of the invention.
EXAMPLE 1
Sample compositions were prepared by mixing a base fluid with various amounts and grades of fibers. The base fluid comprised an aqueous suspension of 1.64% bentonite clay by weight. For some sample compositions, fibers were mixed into the base fluid. The fibers that were used were either (i) glass fibers, having a mean length of 3 millimeters, commercially available from Saint Gobain Vetrotex, of Madrid, Spain; or (ii) basalt fibers, having a mean length of 6 millimeters, commercially available from Sudaglass Fiber Technology. The AR glass fibers were strand cut to a length of about 3 millimeters with a diameter of about 20 microns, and thus had an aspect ratio of 150. The basalt fibers were strand cut to a length of about 6 millimeters and had a mean aspect ratio in the range of from about 230 to about 660. The sample compositions were charged into a cement fluid loss cell used for measurement of cement slurry losses as described in API Recommended Practice 1OB, Twenty-Second Edition, December 1997. The volume of fluid loss for each sample composition was measured as a function of time, and was calculated for 30-minute fluid losses according to the equations provided in the aforementioned API manual.
Sample Composition No. 1 comprised 600 cubic centimeters of water and 10 grams of bentonite clay, with no fibers.
Sample Composition No. 2 comprised the base fluid and AR glass fibers in an amount of about 1.98 pounds per barrel.
Sample Composition No. 3 comprised the base fluid and AR glass fibers in an amount of about 4.95 pounds per barrel. Visual observation of Sample Composition No. 3 indicated that the glass fibers and the bentonite clay formed lumps of a gelatinous mass.
Sample Composition No. 4 comprised the base fluid and basalt fibers in an amount of about 1.98 pounds per barrel.
Sample Composition No. 5 comprised the base fluid and basalt fibers in an amount of about 4.95 pounds per barrel. Visual observation of Sample Composition No. 5 indicated that the basalt fibers and the bentonite clay formed lumps of a gelatinous mass.
The results of the testing are set forth in Table 1, below.

Example 1 demonstrates, inter alia, that the lost circulation materials of the present invention reduce lost circulation.
EXAMPLE 2
A cement fluid loss cell, illustrated in Figures 1 and 2, was equipped on the bottom end with hemispherical plates that were attached (via screws) to a plate having an elliptical opening that was aligned to match with spacing of the hemispherical plates. The hemispherical plates were spaced apart to provide a slit having a predefined width. The bottom plate assembly was secured to the bottom of the pressure chamber with a set of threaded metal rings, and the top of the pressure vessel was equipped with a lid having an attachment for connection with a pressurized gas supply. The slot width was fixed at 0.01 inches, and the slot length was fixed at 1.75 inches. A fluid volume of 200 milliliters of a mud comprising about 6.25% bentonite by weight was used to charge the vessel for each run. After the vessel was charged, air pressure of 100 psi was applied, and the time of the run (e.g., the time until all fluid was lost through the slit) was monitored.
Sample Composition No. 6 comprised the base fluid, with no fibers added. Sample Composition No. 7 comprised the base fluid, with 2 grams of AR glass fibers that had been strand cut to a length of 3 millimeters.
Sample Composition No. 8 comprised the base fluid, with 5 grams of AR glass fibers that had been strand cut to a length of 3 millimeters.
Sample Composition No. 9 comprised the base fluid, with 10 grams of AR glass fibers that had been strand cut to a length of 3 millimeters.
Sample Composition No. 10 comprised the base fluid, with 2 grams of basalt fibers that had been strand cut to a length of 6 millimeters.
Sample Composition No. 11 comprised the base fluid, with 5 grams of basalt fibers that had been strand cut to a length of 6 millimeters.
Sample Composition No. 12 comprised the base fluid, with 10 grams of basalt fibers that had been strand cut to a length of 6 millimeters.
Sample Composition No. 13 comprised the base fluid, with 2 grams of AR glass fibers that had been strand cut to a length of 6 millimeters.
Sample Composition No. 14 comprised the base fluid, with 5 grams of AR glass fibers that had been strand cut to a length of 6 millimeters.
Sample Composition No. 15 comprised the base fluid, with 10 grams of AR glass fibers that had been strand cut to a length of 6 millimeters.
The results of the testing are set forth in Table 2, below.
