Description

WO 2014/070144 PCT/US2012/062590 DRILLING FLUID COMPOSITIONS AND METHODS FOR USE THEREOF IN SUBTERRANEAN FORMATIONS BACKGROUND [0001] The present invention generally relates to drilling fluids, and more specifically, to methods for drilling in a subterranean formation and drilling fluid compositions adapted for the same. [0002] Subterranean wells are drilled for a number of applications, including oil and gas exploration (e.g., wireline core drilling), water exploration, and mineral exploration. In a typical drilling operation, drilling fluid is used during drilling, for example, to control formation pressures, seal permeable formations (e.g., form a filter cake), remove cuttings from the well, and cool and lubricate the drill bit. Although the function of the drilling fluid is generally the same across all applications (e.g., oil and gas, water, and mining), the properties of the drilling fluid must be adapted to each particular application. For example, mining applications, particularly mining exploration applications, tend to involve smaller wellbores and, thus, smaller drill bits, than oil and gas applications. Moreover, drilling during mining exploration tends to involve highly mineralized formations and the integrity, pH, and temperature of these formations may be vastly variable. Moreover, drilling during mining exploration is characterized by and small annular spaces between the formation and the drilling apparatus. Therefore, such applications may require less viscous drilling fluids such that the pressure exerted by the drilling fluid does not damage the formation or drilling fluids that do not vary in its consistency with changing pH or temperature. [0003] Traditional drilling fluids use clay derivatives (e.g., bentonite) that help build the filter cake and control water loss during drilling. They can also be used to suspend cuttings created during drilling and carry them out of the wellbore. However, clay derivatives alone can become too viscous to be adequately pumped and can produce a thick, unstable filter cake, which can create undesirable drag during drill bit pullback. Therefore, suspension enhancers are often added to drilling fluids with clay derivatives in order to reduce the amount of clay derivatives that must be used. In some instances, suspension enhancers additionally serve as water loss reducers. In traditional drilling fluids, suspension enhancers are not used in drilling fluids alone because 1 they do not provide adequate fluid loss control or filter cake production in all formation and water types. [0004] Traditional drilling fluids must be prepared on site in order to account for the variability in formation properties and which may significantly delay drilling operations. Additionally, a particular order of operations for including additives is necessary to ensure that the drilling fluid functions properly for the particular application. For example, if a drilling fluid contains a clay derivative and suspension enhancer (e.g., polymer), it is necessary to hydrate the clay derivative before adding the suspension enhancer in order to ensure that the clay derivative is capable of maximum swelling. If the suspension enhancer is added to a drilling fluid before the clay derivative, the suspension enhancer will interfere with the grains of the clay derivative and prevent it from properly swelling, thereby rendering the drilling fluid less effective. Moreover, the suspension enhancers selected for use in a drilling fluid must be compatible with the particular application (e.g., a polymer that loses its water loss control capacity at high temperatures should not be used in a formation that has high temperature intervals). Also, operator error in mixing drilling fluids tends to lead to inconsistent blends. [0004a] A reference herein to a patent document or other matter which is given as prior art is not to be taken as an admission that that document or matter was known or that the information it contains was part of the common general knowledge as at the priority date of any of the claims. [0004b] Throughout the description and claims of the specification, the word "comprise" and variations of the word, such as "comprising" and "comprises", is not intended to exclude other additives, components, integers or steps. 2 SUMMARY OF THE INVENTION [0005] The present invention generally relates to drilling fluids, and more specifically, to methods for drilling in a subterranean formation and drilling fluid compositions adapted for the same.

[0008] In still other embodiments, the present invention provides a method comprising: drilling a wellbore into a subterranean formation; providing a drilling fluid comprising an aqueous base fluid; providing a property control package in a dry state, the property control package comprising: a finely ground clay derivative present in an amount of less than about 95% by dry weight of the property control package, wherein the clay derivative is selected from the group consisting of: a kaolinite clay; a montmorillonite clay; an illite clay; a chlorite clay; and any combination thereof; a stabilizing agent present in an amount of less than about 75% by dry weight of the property control package, wherein the stabilizing agent is selected from the group consisting of: a non-aqueous tackifying agent; an aqueous tackifying agent; an emulsified tackifying agent; a silyl modified polyamide compound; a resin; a crosslinkable aqueous polymer composition; a polymerizable organic monomer composition; a stabilizing agent emulsion; a zeta-potential modifying aggregating composition; a silicon-based resin; a binder; and any combination thereof; a filtration control agent present in an amount of less than about 50% by dry weight of the property control package, wherein the filtration control agent is: a cellulose; a latex polymer; a copolymer of 3a acrylamido-2-methyl-2-propanesulfonic acid; any derivative thereof; and any combination thereof; and a suspension enhancer present in an amount of less than about 35% by dry weight of the property control package, wherein the suspension enhancer is selected from the group consisting of: naturally occurring gelling agents; synthetic gelling agents; and any combination thereof; introducing the property control package into the drilling fluid; introducing the drilling fluid comprising the property control package into the wellbore in the subterranean formation; and continuously circulating the drilling fluid during the drilling of the wellbore. [0009] The features and advantages of the present invention will be readily apparent to those skilled in the art upon a reading of the description of the preferred embodiments that follows. DETAILED DESCRIPTION [0010] The present invention generally relates to drilling fluids, and more specifically, to methods for drilling in a subterranean formation and drilling fluid compositions adapted for the same. 3b WO 2014/070144 PCT/US2012/062590 [0011] In order to address the difficulties associated with drilling fluids used in drilling operations in variable subterranean formations and for variable applications, the present invention provides a combination of additives that may be added as a property control package to desirably change the properties of a drilling aqueous base fluid in a synergistic manner. The property control packages described herein improve the ease with which the drilling fluid may be prepared and introduced into the wellbore as well as their use in various formation conditions (e.g., temperature and pH). Altering these factors in concert with one another may address the particular difficulties associated with traditional drilling fluids. [0012] To facilitate the ease of preparing and introducing the drilling fluids into a wellbore (e.g., the ease of pumping), the property control packages described herein contain a filtration control agent. The filtration control agent helps to maintain the fluidity of the drilling fluid by reducing water loss to the formation. In addition, the filtration control agent desirably maintains sufficient water in the drilling fluids for effective lubrication and cooling of the drill bit during drilling operations. [0013] Despite the foregoing advantages of the filtration control agent, the presence of the filtration control agent may decrease the ability of the drilling fluids of the present invention to suspend cuttings and carry them to the head of the wellbore. Therefore, in addition to the filtration control agent, the property control packages of the present invention also include a suspension enhancer. The suspension enhancer may work in concert with the filtration control agent to increase the viscosity of the drilling fluid while providing adequate fluid loss control. [0014] The property control packages of the present invention may contain clay derivatives and/or suspension enhancers. Although clay derivatives and suspension enhancers have not previously been admixed together prior to their hydration because the suspension enhancers interact with the clay derivatives to hinder their swelling ability, the clay derivatives in the property control packages of the present invention may be admixed with the suspension enhancers without interfering with the swelling of the clay derivatives. The novel clay derivates in the property control packages described herein are finely ground which unexpectedly prevents the suspension enhancers from interacting with the clay derivatives such that the clay derivatives are able to reach a 4 WO 2014/070144 PCT/US2012/062590 preferred swelling amount without first hydrating them before adding the suspension enhancers. Property control packages containing suspension enhancers and no clay derivatives may be beneficial for drilling small wellbores (i.e., during mineral exploration operations) because the suspension enhancers may impart water loss and sufficient viscosity, without being overly thick as it would be with clay derivatives admixed. [0015] Although the foregoing additives of the property control packages of the present invention may impart the advantages described herein to a drilling fluid when used in combination with one another, they are not believed to chemically interact directly with one another, either positively or negatively, particularly in a dry or powdered state, thereby allowing their ready combination with one another for later inclusion in a drilling aqueous base fluid. [0016] In some embodiments, the present invention provides for a method comprising: drilling a wellbore into a subterranean formation; providing a drilling fluid comprising an aqueous base fluid and a property control package, the property control package comprising: a stabilizing agent; a filtration control agent; and a suspension enhancer; introducing the drilling fluid into the wellbore in the subterranean formation; and continuously circulating the drilling fluid during the drilling of the wellbore. In other embodiments, the present invention provides for a method comprising: drilling a wellbore into a subterranean formation; providing a drilling fluid comprising an aqueous base fluid and a property control package, the property control package comprising: a clay derivative; a stabilizing agent; a filtration control agent; and a suspension enhancer; introducing the drilling fluid into the wellbore in the subterranean formation; and continuously circulating the drilling fluid during the drilling of the wellbore. . AQUEOUS BASE FLUID [0017] The aqueous base fluid for use in the drilling fluids of the present invention may be any aqueous fluid suitable for use in subterranean drilling applications. Suitable aqueous base fluids may include, but are not limited to, fresh water, saltwater (e.g., water containing one or more salts dissolved therein), brine (e.g., saturated salt water), seawater, or combinations thereof. Generally, the water may be from any source, provided that it does not contain components that might adversely affect the stability and/or performance of the drilling fluids of the present invention. In certain embodiments, the 5 WO 2014/070144 PCT/US2012/062590 density of the aqueous base fluid can be adjusted, among other purposes, to provide additional particulate transport and suspension in the aqueous base fluids used in the methods of the present invention. In certain embodiments, the pH of the aqueous base fluid may be adjusted (e.g., by a buffer or other pH adjusting agent), among other purposes, to activate a crosslinking agent (e.g., the suspension enhancer) and/or to reduce the viscosity of the drilling fluids (e.g., activate a breaker, deactivate a crosslinking agent). In these embodiments, the pH may be adjusted to a specific level, which may depend on, among other factors, the component properties of the property control package of the drilling fluid and/or the properties of the formation itself. In some embodiments, the pH range may preferably be from about 4 to about 11. One of ordinary skill in the art, with the benefit of this disclosure, will recognize the type of aqueous base fluid to use in a particular drilling operation and when density and/or pH adjustments are appropriate. II. PROPERTY CONTROL PACKAGE - CLAY DERIVATIVE [0018] Any suitable clay derivative that is capable of imparting a viscosity to the drilling fluids of the present invention in order to aid in controlling fluid loss and building a suitable filter cake along the face of a subterranean formation may be used in the property control packages of the present invention. Suitable examples of clay derivatives may include, but are not limited to, the derivatives of kaolinite clay, montmorillonite clay, illite clay, chlorite clay, and combinations thereof. In preferred embodiments, the clay derivative is comprised of a montorillonite clay, such as bentonite. In some embodiments, the clay derivative is present in an amount in the range of from about 0% to about 95% by dry weight of the property control package. In preferred embodiments, the clay derivative is present in an amount in the range of from about 70% to about 95% by dry weight of the property control package. [0019] The clay derivatives of the present invention may include any impurities such as, for example, organic matter (e.g., humus, carbonaceous shale), fossilized matter, lime carbonate, iron oxides, iron suphides, rock salt, wavellite, and sand. Impurities may be present in the clay derivatives of the present invention in an amount from less than about 20% by dry weight of the clay derivative. Preferably, impurities are present in the clay derivatives of the present invention in an amount from less than about 10% by dry weight of the clay derivative. 6 WO 2014/070144 PCT/US2012/062590 III. PROPERTY CONTROL PACKAGE - STABILIZING AGENT [0020] The stabilizing agent of the property control packages of the present invention may be used to control the swelling of the clay derivative in order to reach a preferred swelling amount and to reduce the clay derivatives migration into formation pores.
