High water and brine swell elastomeric compositions and method for making and using same

Swellable elastomeric compositions including an elastomer, a covalent crosslinking system and an ionic crosslinking system, where the composition have improved rate of swelling in water, brines and aqueous solutions, swellability, and/or physical properties of the compositions.

A hybrid swellable material employs an oleophilic elastomer as a matrix admixed with an organic material derived from soy that is water swellable in brine, as well as fresh water. Various downhole tools may be made using this hybrid swellable material.

A high pressure seal material, such as for a lateral 'T' seal of a shear ram blowout preventer, is disclosed wherein the seal material is preferably nitrile rubber and includes uniformly dispersed synthetic, non-cellulosic fibers in parallel alignment to resist rollover action occurring transverse to the applied compressive force by orienting the aligned fibers parallel to the axis of the applied force. The material is made in a milling process that aligns and maintains the alignment of the fibers. The milled sheet is then cut into appropriately shaped pieces. The pieces are rotated 90.degree., plied and cured to make the final material, which curing can be done in a suitable mold so that the final product is in its desired final shape.

A carbon black system for manufacturing rubber comprises a pair of carbon blacks having the same structure, a fumed silica and a silane coupler. One of the pairs of carbon blacks has an Iodine Adsorption No. of less than 115 and the other pair of carbon blacks has an Iodine Adsorption No. of greater than 115. A rubber composition comprises a rubber selected from a group of polar and nonpolar rubbers, a carbon black system comprising a pair of furnace carbon blacks with both of the pairs of carbon blacks having the same structure, a fumed silica and silane coupler. One of the pairs of carbon blacks has an Iodine Adsorption No. of less than 115 and the other pair has an Iodine Adsorption No. of greater than 115. The carbon black system is from about 40 parts per hundred to about 80 parts per hundred of the rubber. The ratio of either pair of carbon blacks to the other in the rubber does not exceed 3:1.

Carbon black pair with different particle size and improved rubber stock

An improved rubber stock with a unique carbon black system including mismatched pairs of furnace blacks with fumed silica and a silane coupler has been developed. The carbon black system includes a mixture of large and small particles with high and low structure carbon black pairs. The carbon black system compounded with polar and nonpolar rubber provides products with a range of desirable characteristics using only two carbon blacks.

A rubber composition with small fluorocarbon micro-powder particles incorporated into the composition which reduces the coefficient of friction. The rubber with a lowered coefficient of friction allows for ease of movement of the rubber part against metal surfaces thereby reducing the wear of the rubber part.

Rubber and fluorocarbon micropowder composition

A composition for use in piping and pump systems for elevated temperature, steam and certain chemical resistant applications of ethylene-propylene copolymer with peroxide generated carbon to carbon crosslinkage. Effective amounts of antioxidants, carbon black, lubricant, thermal stabilizer and aid to peroxide crosslinkage is added. An antioxidant and thermal stabilizer system is used to produce a product with unusual thermal stability characteristics. The composition may also have a mixture of high and low particle size carbon black which acts as an antioxidant and reinforcing system. The composition may also use very fine particle carbon black for a highly elastic application. The composition can be used for rubber components which are exposed to a high temperature or to certain chemical environments, or where unusually high elasticity is required.

Chemical and heat resistant rubber composition

A composition for use in geothermal or high temperature and steam applications of ethylene-propylene copolymer with peroxide generated carbon to carbon crosslinkage. Effective amounts of antioxidants, carbon black, lubricant, thermal stabilizer and aid to peroxide crosslinkage is added. An antioxidant and thermal stabilizer system is used to produce a product with unusual thermal stability characteristics. The composition also has a mixture of high and low particle size carbon black which act as an antioxidant and reinforcing system. The composition can be used for rubber components in geothermal drilling for pipe protectors, valve seals and other products which are exposed to a high temperature and steam saturated environment.
