BACKGROUND OF THE INVENTION Field of the Invention

The present invention provides amidic polymers, which exhibit shale swelling inhibitor activity having improved biodegradability. The amidic polymers of the invention may be employed in a wide variety of compositions, particularly in subterranean drilling operations.

Description of Related Art

Subterranean drilling operations are procedures conducted below the surface of the earth from a formation such as in the course of recovering oil, gas, and other substances. Typically, rotary subterranean drilling operations involve attaching a drill bit on a lower end of a drill string to form a drilling tool and rotating the drill bit along with the drill string into a subterranean formation to create a well bore through which subsurface formation fluids may be recovered. During subterranean drilling operations, subterranean well bores may encounter strata having reactive shales. Reactive shales are materials like clays (bentonite) and other subterranean materials that swell when exposed to water. Reactive shales can cause problems during drilling because of their tendency to degrade when exposed to aqueous media such as aqueous-based drilling fluids. This degradation can result in undesirable drilling conditions because degradation of the shale may interfere with attempts to maintain the integrity of drilled cuttings traveling up the well bore until the cuttings can be removed by solids control equipment located at the surface. Degradation of drilled cuttings prior to their removal at the surface greatly prolongs drilling time because the shale particles traveling up the well bore break up into smaller particles. These smaller particles increasingly expose new surface area of the shale to the drilling fluid, which leads to still further absorption of water and further degradation.

Consequently, subterranean drilling operations generally employ drilling fluids to inhibit shale swelling and improve environmental performance. Drilling fluids used in such operations may be fluids (gaseous or liquid), mixtures of fluids, and solids (solid suspensions, emulsions, gases and solids). Drilling fluids are also used to cool the drill bit, lubricate the rotating drill, prevent blowouts, and remove drill cuttings from the well bore.

Shale disintegration may also affect Equivalent Circulating Density (ECD). ECD is the increase in bottom hole pressure due to friction and is normally expressed in pounds per gallon. ECD, when forward circulating, is the apparent fluid density, which results from adding annular friction to the actual fluid density in the well. ECD may be affected by the solids content of the drilling fluid, which may increase if surface solids control equipment cannot remove shale from the drilling fluid. Plastic viscosity (an indicator of size and quantity of solids) is an important parameter that affects drilling rate. Maintenance of appropriate ECD is important in drilling a well bore where a narrow tolerance exists between the weight of the drilling fluid needed to control the formation pressure and the weight of the drilling fluid that will fracture the formation. In such circumstances, minimizing shale degradation may be desirable to control the viscosity of the drilling fluid. Shale degradation may substantially decrease the stability of the well bore, which may cause irregularities in the diameter of the well bore. Shale degradation may decrease the stability of the well bore to such an extent that the well bore collapses. Degradation of the shale also may interrupt circulation of the drilling fluid, cause greater friction between the drill string and the well bore. Accordingly, the complications associated with shale swelling during drilling may substantially increase the time and cost of drilling.

Background material on shale swelling inhibitors include U.S. Pat. Nos. 7,087,554, 7,549,474, and 7,833,945. Further background includes A. V. Reis, et al., J. Org. Chem., 2009, 74, 3750-3757; U.S. Pat. No. 5,037,930; S. H. Kim, et al., Carbohydrate Polymers 40 (1993) 180-190; and Fhilype J., et al., International Journal of Pharmaceutices 335 (2008) 184-194.

Traditional methods for inhibiting shale swelling during drilling have employed oil-based and synthetic-based drilling fluids. However, water-based shale swelling drilling inhibitors are now generally used because they are considered more environmentally friendly. Many shale swelling inhibitors show good inhibition performance in the oilfield but their application may be limited because of poor biodegradability. Accordingly, there is a need for shale swelling inhibitors having improved biodegradability.

The filler particles may be of any appropriate size, particularly from the nano to micro range. The choice of such size for any particular end use is within the expertise of one skilled in the art. The filler may be present in an amount from about 10% to about 90% by weight of the total composition. More than one filler type may be used in a composition and the fillers may or may not be surface treated. Appropriate filler sizes can be determined by the practitioner, and, in particular, may be within the range from about 20 nm to about 100 μm.

Other materials, such as adhesion promoters (e.g. epoxides, silanes), dyes, pigments, and rheology modifiers may be added as desired for the modification of the final properties. Such materials and the amounts needed are within the expertise of those skilled in the art.

Compositions belonging to the personal care/cosmetic and pharmaceutical arts find utility in altering, delivering an active, enhancing, improving, modifying the appearance, condition, color, health, style of the skin (including face, scalp, and lips), hair, nails, and oral cavity. Many examples and product forms of these compositions are known. These compositions can impart benefits that include, but are not limited to, hair style flexibility, hair style durability, humidity resistance for hair, color and/or color protection, moisturization, wrinkle reduction, protection from ultraviolet radiation, water proofness, water resistance, wear resistance, thermal protection, adhesion, active ingredient delivery, anti-cavity, and/or anti-gingivitis protection. As such, these compositions are sometimes categorized in the following areas: skin care, hair care (both styling and non-styling), sun care, cosmetics (including color cosmetics), antiperspirants, deodorants, oral hygiene, and men's and women's personal hygiene/grooming, In some cases these benefits and care areas overlap with another.

Skin care compositions include those materials used on the body, face, hands, lips, and/or scalp, and are beneficial for many reasons, such as firming, anti-cellulite, moisturizing, nourishing, cleaning, reducing or eliminating the appearance of wrinkles or lentigo, toning, and/or purifying. They also can be used to sanitize.

Consumers can identify many of the compositions that serve the sun care area, for example after-fun, children's, beach, self-tan, sports (i.e., being sweat proof, waterproof, resistant to running, or having added UV absorbers and/or antioxidants), sensitive skin products (i.e., having low irritation to the eyes and/or skin, and/or being free of fragrances and/or dyes), daily wear, leave-on hair creams, lotions, styling products, and hair sprays, Typically, sun care products also comprise one or more UV actives, which are those organic and inorganic materials that scatter, absorb, and/or reflect radiation having a wavelength from about 100 nm to about 400 nm. In one aspect, the sun care product protects against UV-A and/or UV-B radiation. UV-A radiation, from about 3:20 nm to about 400 nm, has the longest wavelength within the UV spectrum, and consequently is the least energetic. While UV-A rays can induce skin tanning, they are liable to induce adverse changes as well, especially in the case of sensitive skin or of skin, which is continually exposed to solar radiation. In particular UV-A rays cause a loss of skin elasticity and the appearance of wrinkles, leading to premature skin aging. UV-B rays have shorter wavelengths, from about 290 nm to about 320 nm, and their higher energy can cause erythema and skin burns, which may be harmful. Alternatively, sun care products may omit UV actives, and may be regarded as a tanning oil or a tan promoter. Some sun care compositions may promote soothe skin after sun exposure, and/or be formulated for application to the lips, hair, or the area around the eyes. Self-tan compositions, which are products that color skin without requiring full sun exposure, also fit under the sun care umbrella. The many different sun care product formats include may assume a consistency ranging from liquid to semiliquid forms (e.g., milks, creams), to thicker forms like gels, creams, pastes, and even solid- and wax-like forms. Sun care products also may take the form of an aerosol, spray, mist, roll-on, or wipe.

Hair care compositions include shampoos, leave-on and rinse-out conditioners used for conditioning, moisturizing, repairing, hair colors, hair relaxers, and deep conditioners and treatments such as hot oils and waxes, 2-in-1 shampoo/conditioner combination products, 3-in-1 shampoo/conditioner/styling agent. The many types of hair care products can be delivered in an array of formats, including aerosol sprays, pump sprays, gel sprays, mousses, gels, waxes, creams, pomades, spritzes, putties, lacquers, de-frizzing serums, perms, relaxants and colorants.

Color cosmetic compositions include facial make-up, eye makeup, mascaras, lip and nail products. Facial make-up compositions include foundation (liquid, solid, and semi-solid) skin tinted creams, liquid, sticks, mousses used as a base under make-up, rouge, face powder, blusher, highlighters, face bronzers, concealers, and 2-way cake products.

Pet care/cosmetics also include eye make-up, mascaras, eyeliners, eye shadows, eyebrow pencils and eye pencils. Lip products include lipsticks, lip pencils, lip gloss, transparent bases and tinted lip moisturizers as well as multi-function color sticks that can also be used for cheeks and eyes. Nail products include nail varnishes/enamels, nail varnish removers, treatments, home-manicure products such as cuticle softeners and nail strengtheners.

In addition to the skin, hair, and sun care compositions summarized above, the polymers related herein also find application in oral care compositions. Non-limiting examples or oral care compositions include toothpastes (including toothpaste gels), denture adhesives, whiteners, anesthetics, and dental floss and related products. These compositions may take any product format, such as pastes, gels, creams, solutions, dispersions, rinses, flosses, aerosols, powders, and lozenges.

Grooming products for men and women include shaving products and toiletries, which may find use in preparing the skin and/or hair for dry or wet shaving. In addition, these compositions may help to moisturize, cool, and/or soothe skin. A variety of product forms are known, a few of which are foams, gels, creams, sticks, oils, solutions, tonics, balms, aerosols, mists, sprays, and wipes.

The polymer can also be used in other personal care/cosmetic applications, such as an absorbent material in appropriate applications such as diapers, incontinence products, feminine products, and other related products.

The polymers described herein also find application in bath and shower compositions, such as foams, gels, salts, oils, balls, liquids, powders and pearls. Also included are bar soaps, body washes, shower gels, cleansers, gels, oils, foams, scrubs and creams. As a natural extension of this category, these compositions also include liquid soaps and hand sanitizers used for cleaning hands.

Reaction mixture was refluxed for 6 hours and then was cooled to room temperature to discharge the product. The reaction mixture was washed by acetone three times and the precipitate was dried in oven. The product obtained was a yellowish powder with a yield of 68.75%.

Example 23

In a 1-L reactor was equipped with thermocouple, nitrogen inlet and reflux condenser, 48.5 g Celluosize HEC-15 powder (from Dow), 30 g DI water and 170 g isopropyl alcohol (IPA) were added. The reaction mixture was stirred overnight at room temperature. The reaction mixture was heated to 50° C. and then 2.0 g NaOH aqueous solution (50%) was added. After 2 hours of reaction, 1.5 g GMA was added to the reactor. The reaction temperature was raised to 70° C. and maintained for 5 hours. Then, the reaction mixture was cooled to 50° C. and HPVP (50.0 g) was added into the reactor. The reactor was sparged with nitrogen for 30 minutes and then 0.5 g Trigonox 25 C75 was added. The reaction was maintained for 1 hour and then was raised to 60° C. One hour later, the reaction mixture was increased to 70° C. and held for 3.5 hours. Two more shots of 0.2 g Trigonox 25 C75 were added into the reactor after 2 hours. The residual VP of the final product was 0.1%.

Example 24

The method of Example 5 was followed with the following change: solvent exchange was applied to replace IPA with water. The final obtained was 16% solids in water.

Example 24 Shale Swelling Inhibition Testing

The shale swelling inhibition performance was evaluated using the Roller Oven test. The test procedures are following:

  • 1). Prepare 400 g of the polymer solution to be evaluated.
  • 2). Weigh the required amount of polymer solution and water into a 500 ml glass bottle with lid.
  • 3). Add 40 g of KCl and heat with stirring to 71° C. (160° F.).
  • 4). Add 10 g (to 2 decimal places) of the 2-4 mm London clay to the test fluid and record weight.
  • 5). Screw on the bottle cap and shake the sample by hand for 10 seconds.
  • 6). Place the bottle on the roller mixer with the IR lamp at 20 r/min and leave for 16 hours.
  • 7). Remove from the mixer and heat and allow to cool for 1 hour. Pour the contents of the bottle into a 500 μm sieve, retaining the clay and disposing of the test fluid.
  • 8). Rinse the bottle with water and pour onto the sieve until all the shale has come out of the bottle.
  • 9). Wash the shale in the sieve by immersing in a tray of water.
  • 10). Dry sieve and contents at 121° C. to constant weight.
  • 11). Weigh the dried shale and report as a percentage of the original 10 g.

The shale recovery is determined by the formula:

Shale Recovery % = Weight recovered shale Weight of the Orginal Shale × 100 %

The performance (inhibition efficiency) is shown by (shale recovery rate), solution appearance after hot rolled, and change of the clay particle size. A good shale swelling inhibitor will give a higher shale recovery value and the test solution, after being rolled in a roller oven for 16 hrs, aill be less muddy. Recovered clay particles for a good shale swelling inhibitor do not change greatly before and after the test.

Example 25 Salt Tolerance Test

The salt tolerance of a shale swelling inhibitor was evaluated using the following procedure:

  • 1). Prepare 10:26% KCl solution by dissolving a KCl powder into DI water in a glass jar.
  • 2). Add polymer into the 10.26 KCl aqueous solution to make 1% polymer solution.
  • 3). Transfer the polymer solution prepared above try a glass made pressure tube.
  • 4). Pre-set an oven to 120° C.
  • 5). Leave the pressure tube in the oven for overnight.
  • 6). Observe the appearance of the solution.

Salt tolerance of shale swelling inhibitor is determined by the appearance of test solutions. Polymers that have good salt tolerance do not precipitate out of solution.
