Definitions
- the present invention relates to chemical treatments for oil and gas wells. More particularly, the present invention relates to methods and compositions for enhancing the coverage and displacement of treatment fluids into subterranean formations.
- Chemical treatments for oil and gas wells often involve sequential injections of one or more fluids, such as a preflush, chemical agent, spacer, and/or afterflush.
- treatment fluids are injected into a subterranean formation at the matrix flow rate, i.e., the rate at which the treatment fluid enters laminar flow inside the formation. At this rate the treatment fluid enters the interstitial spaces of the formation at a flow rate low enough to avoid generating areas of high pressure within the formation that could cause the formation to fracture inadvertently.
- the success of these treatments often relies on the effective coverage and displacement of one fluid by another. Unfortunately, problems of uneven distribution or placement of treatment fluids are often encountered in well bores containing multiple layers with highly variable permeabilities.
- Paccaloni's maximum pressure differential and injection rate (“MAPDIR”) method, which uses the injection rate as the key parameter to obtain a desired bottomhole pressure differential.
- MAPDIR maximum pressure differential and injection rate
- Paccaloni's MAPDIR method and other methods involving high injection rates have not been widely adopted outside of acid stimulation treatments. This is due to the fact that many other treatment fluids, such as curable resins, are too viscous to be pumped into a formation at a flow rate sufficiently high enough to maximize the pressure differential without fear of inadvertently fracturing the formation.
- traditional solvents that could be used to lower the viscosity of the treatment fluids also tend to render the fluids less capable of adequately coating the formation, sometimes defeating the purpose of injecting the fluids into the formation.
- the present invention relates to chemical treatments for oil and gas wells. More particularly, the present invention relates to methods and compositions for enhancing the coverage and displacement of treatment fluids into subterranean formations.
- a method of injecting a treatment fluid into a portion of a subterranean formation comprising providing a treatment fluid having a viscosity; determining the breakdown pressure of the portion of the subterranean formation; calculating the maximum sustainable flow rate for the treatment fluid; and, injecting the treatment fluid into the portion of the subterranean formation at a flow rate less than or equal to the maximum sustainable flow rate for the treatment fluid.
- a method of injecting a treatment fluid into a portion of a subterranean formation comprising providing a treatment fluid having a viscosity; determining the breakdown pressure of the portion of the subterranean formation; calculating the maximum allowable treatment fluid viscosity; adjusting the viscosity of the treatment fluid to a viscosity less than or equal to the maximum allowable treatment fluid viscosity; and injecting the treatment fluid into the subterranean formation at the selected treatment fluid flow rate.
- the present invention relates to chemical treatments for oil and gas wells. More particularly, the present invention relates to methods and compositions for enhancing the coverage and displacement of treatment fluids into subterranean formations.
- a treatment fluid may be injected into a subterranean formation at a combination of a flow rate and a viscosity selected to maximize down hole pressure and yet remain below the "breakdown pressure.”
- breakdown pressure refers to a pressure at which the treating pressure exceeds the strength of the rock and the formation fractures.
- This flow rate may be thought of as the maximum rate condition that can be achieved while staying below the fracture gradient.
- the viscosity of the treatment fluid may also be adjusted in addition to, or in place of, adjusting the flow rate, to maximize the down hole pressure.
- the ability to inject treatment fluids into a subterranean formation at or near the breakdown pressure of the formation may offer numerous benefits.
- maximizing the down hole pressure by controlling the flow rate and/or the viscosity of the treatment fluid may allow the coverage of the treatment fluid to be extended into the subterranean formation, despite the presence of portions of the subterranean formation to be treated having areas of varying permeabilities along the length of the well bore.
- the coverage of a fluid in the formation and/or its displacement efficiency may be enhanced by adjusting the injection rate and/or viscosity of a later- introduced treatment fluid. Because each fluid in the treatment has its own viscosity, the injection rate of each fluid may be adjusted such that the maximum allowable injection pressure for each fluid is maintained while that fluid is being injected down hole without fracturing the formation. Thus, using tailored flow rates and tailored viscosities combined with MAPDIR pumping procedures, longer intervals of the well bore may be treated more effectively.
- treatment fluids may be injected into a subterranean formation in accordance with teachings of the present invention.
- the treatment fluid may comprise a curable resin.
- Other embodiments of the present invention may use a treatment fluid comprising a water controlling agent.
- Resins suitable for use as treatment fluids in the present invention include all resins known in the art that are capable of forming a hardened, consolidated mass. Many such resins are commonly used in subterranean consolidation operations, and some suitable resins include two component epoxy based resins, novolak resins, polyepoxide resins, phenol- aldehyde resins, urea-aldehyde resins, urethane resins, phenolic resins, furan resins, furan/furfuryl alcohol resins, phenolic/latex resins, phenol formaldehyde resins, polyester resins and hybrids and copolymers thereof, polyurethane resins and hybrids and copolymers thereof, acrylate resins, and mixtures thereof.
- suitable resins such as epoxy resins
- suitable resins such as furan resins generally require a time-delayed catalyst or an external catalyst to help activate the polymerization of the resins if the cure temperature is low (i.e., less than 25O 0 F), but will cure under the effect of time and temperature if the formation temperature is above about 25O 0 F, preferably above about 300 0 F. It is within the ability of one skilled in the art, with the benefit of this disclosure, to select a suitable resin for use in embodiments of the present invention and to determine whether a catalyst is required to trigger curing.
- Selection of a suitable resin may be affected by the temperature of the subterranean formation to which the fluid will be introduced.
- a bottom hole static temperature BHST
- two-component epoxy-based resins comprising a hardenable resin component and a hardening agent component containing specific hardening agents may be preferred.
- a furan- based resin may be preferred.
- a phenolic-based resin or a one-component HT epoxy- based resin may be suitable.
- a phenol/phenol formaldehyde/furfuryl alcohol resin may also be suitable.
- Water controlling agents may also be suitable treatment fluids in the present invention.
- agents have been used to reduce the water permeability of subterranean formations, such as surfactants formed of one or more fatty acid imidazolyl compounds and water-resistant polymers.
- Water-resistant polymers also known as relative permeability modifiers, act, inter alia, to adsorb onto the surfaces within the pores of a formation to reduce the formation's water permeability.
- a variety of water-resistant polymers are suitable for use as water controlling agents in the present invention.
- polyacrylamide examples include, but are not limited to, polyacrylamide, hydrolyzed polyacrylamide, xanthan, scleroglucan, polysaccharides, amphoteric polymers made from acrylamide, acrylic acid, diallyldimethylammonium chloride, vinyl sulfonate/vinyl amide/acrylamide terpolymers, vinyl sulfonate/acrylamide copolymers, acrylamide/acrylamido-methylpropanesulfonic acid copolymers, acrylamide/vinylpyrrolidone copolymers, sodium carboxymethyl cellulose, polyfdialkylaminoacrylate-co-acrylate-g- poly(ethyleneoxide)], acrylamide/octadecyldimethylammoniumethyl methacrylate bromide copolymer, dimethylaminoethyl methacrylate/vinyl pyrrolidone/hexadecyldimethylammoniummethyl methacrylate bromide copo
- the breakdown pressure of the subterranean formation must first be determined.
- the breakdown pressure of the subterranean formation may be determined using a variety of techniques well-known in the art. Examples of such techniques include, but are not limited to, the analysis of Step Rate Injection Tests, Full Wave Sonic or Dipole Sonic logging tools for mechanical rock properties and stress, the analysis of borehole breakouts during drilling, and minifrac analysis.
- the treating bottom hole pressure is maintained below that of the breakdown pressure. Because once the fractures are generated, the treatment fluids will tend to flow or leakoff into the fractures, defeating the purpose of treating the near well bore area. With the benefit of this disclosure, it should be within the ability of one skilled in the art to select an appropriate method of determine the reservoir stress or fracture gradient.
- the flow rate of the treatment fluid may be calculated by determining the maximum sustainable flow rate that will not result in the fracturing of the formation, given the breakdown pressure of the formation and the viscosity of the treatment fluid to be injected into the formation. Assuming pseudo-steady- state flow, the maximum non-fracturing injection flow rate, qi ⁇ max , is related to the breakdown pressure, pb d , by the following equation:
- p e is the average reservoir pressure
- k is the permeability of the formation
- h is the net pay
- ⁇ is the viscosity of the fluid
- r* is the radius of the formation cylinder in which the majority of the pressure drop takes place
- r w is the well bore radius
- s is the skin factor for the well bore. Additional information on the relationship between injection flow rates, fluid viscosities, and breakdown pressures may be found in MICHAEL J. ECONOMIDES, A. DANIEL HELL & CHRISTINE EHLIG-ECONOMEDES, PETROLEUM PRODUCTION SYSTEMS Ch. 14 (Prentice Hall Petroleum Engineering Series 1994) and G. PACCALONI, M. TAMBINI & M.
- the selected flow rate may be adjusted downwards from the maximum non- fracturing flow rate as an additional measure to further ensure the formation does not fracture inadvertently.
- the selected flow rate may be range from about 80% to about 90% of the maximum non-fracturing flow rate.
- the flow rate is typically monitored in real time to ensure that the desired flow rate is being achieved, as well as to determine when a sufficient amount of the treatment chemical has been injected into the formation.
- particular embodiments of the present invention may manipulate the viscosity of the treatment fluid to maximize the bottom hole pressure of the well bore. Such viscosity manipulation may be particularly useful in cases wherein the treatment fluid is curable resin.
- this reduction in the viscosity of the curable resin may be accomplished by adding a solvent or dispersant to the treatment fluid.
- suitable solvents include, but are not limited to, methanol, isopropanol, butanol, glycol ether solvents, and combinations thereof.
- Suitable glycol ether solvents include, but are not limited to, diethylene glycol methyl ether, dipropylene glycol methyl ether, 2-butoxy ethanol, ethers of a C 2 to C 6 dihydric alkanol containing at least one C 1 to C 6 alkyl group, mono ethers of dihydric alkanols, methoxypropanol, butoxyethanol, hexoxyethanol, and isomers thereof. Selection of an appropriate solvent is dependent on the resin composition chosen and is within the ability of one skilled in the art, with the benefit of this disclosure. Generally, the selected solvent is added to the treatment fluid until the treatment fluid has a lower, desired viscosity. In particular embodiments, the treatment fluid may have viscosity of about 5 to about 30 cP.
- each fluid in the treatment may be injected in the formation at a flow rate tailored to viscosity of the individual fluid being injected, such that the down hole pressure is maximized for each fluid as it is injected.
- a injection technique may also enhance the coverage and/or displacement efficiency of the previously injected fluids, helping treat longer intervals of the well bore more effectively.
- Such tailoring of injection rate may be particularly useful in operations wherein placement of the treatment fluid is preceded by a preflush fluid and/or followed by the placement of an afterflush fluid.
- Preflush fluids suitable for use in the methods of the present invention comprise an aqueous liquid, a surfactant, and an optional mutual solvent.
- the preflush solution readies the formation to receive the integrated consolidation fluid and removes oils that may impede the integrated consolidation fluid from making contact with the formation particles.
- Suitable aqueous liquids that may be used to form the preflush fluid include, but are not limited to, fresh water, salt water, brine, combinations thereof, or any other aqueous liquid that does not adversely react with the other components used in accordance with this invention.
- the mutual solvent should be soluble in both oil and water and be capable, among other things, of removing hydrocarbons deposited on particulates.
- suitable mutual solvents include, but are not limited to, glycol ethers.
- Some suitable glycol ethers include ethyleneglycolmonobutyl ether, diethylene glycol monomethyl ether, diethylene glycol dimethyl ether, dipropylene glycol methyl ether, and combinations thereof.
- Any surfactant compatible with the aqueous liquid and capable of aiding the hardenable resin in coating the surface of unconsolidated particles of the subterranean formation may be suitable for use in the present invention.
- surfactants suitable for use in the preflush fluids used in the methods of the present invention include, but are not limited to, ethoxylated nonyl phenol phosphate esters, one or more cationic surfactants, one or more nonionic surfactants, an alkyl phosphonate surfactant (e.g., a Q 2 -C 22 alkyl phosphonate surfactant), and mixtures thereof.
- alkyl phosphonate surfactant e.g., a Q 2 -C 22 alkyl phosphonate surfactant
- the afterflush fluids suitable for use in the methods of the present invention comprise an aqueous liquid or an inert gas.
- the afterflush fluid is an aqueous liquid, it may be fresh water, salt water, brine, or any other aqueous liquid that does not adversely react with the other components used in accordance with this invention.
- a volume of about 1 to about 5 times the volume of the integrated consolidation fluid used is generally suitable for use in the methods of the present invention.
- Such afterflush fluids may prevent adverse interactions between the afterflush fluid and the formation.
- the afterflush fluid acts, inter alia, to displace the curable resin from the well bore, to remove curable resin from the pore spaces inside the subterranean formation thereby restoring permeability, and to leave behind some resin at the contact points between formation sand particulate to form a permeable, consolidated formation.
- the afterflush fluid further comprises a surfactant.
- a surfactant compatible with the aqueous liquid and capable of aiding the hardenable resin in coating the surface of unconsolidated particles of the subterranean formation may be suitable for use in the present invention.
- surfactants suitable for use in the afterflush fluids used in the methods of the present invention include, but are not limited to, ethoxylated nonyl phenol phosphate esters, one or more cationic surfactants, and one or more nonionic surfactants, and an alkyl phosphonate surfactant (e.g., a C 12 -C 22 alkyl phosphorate surfactant). Mixtures of one or more cationic and nonionic surfactants are suitable and examples are described in U.S. Patent No. 6,311,773 issued to Todd et al. on November 6, 2001, the disclosure of which is incorporated herein by reference.
- a preflush fluid comprising a water controlling agent may be placed into a portion of a subterranean formation, followed by the placement of a resin treatment fluid, optionally followed by an afterflush fluid.
- at least one water controlling agent is included in the preflush fluid in an amount sufficient to reduce the production of water from the formation.
- the water controlling agent is included in the preflush fluid in the range of from about 0.01% to about 10% by weight of the preflush fluid.
- the water controlling agent is included in the preflush fluid in the range of from about 0.1% to about 1% by weight of the pre-flush fluid.
- a fluid placement simulation was performed to illustrate the effectiveness of the method provided therein.
- the simulation involved a well bore having three intervals, having permeabilities of 5,000 mD, 1,000 mD, and 500 mD, consecutively, and a reservoir pressure of 2,000 psi at a depth, of 5,000 ft. For simulation purpose, an interval length of 10 ft is assumed for each interval.
- the treatment fluid was injected into the well at 2, 4, 6, and 8 barrels per minute to determine the effect of injection rate on the penetration distance of the treatment fluid into the formation. It was found that most of the treatment fluid penetrates the 5,000-mD interval, and only a small amount of treatment fluid enters the lower permeability intervals. Even as the injection rate was increased to a higher rate, the penetration depth of treatment fluid into the 500 mD interval was increased just a little.
