An elastomer alloy includes a base polymer including hydrogenated nitrile butadiene rubber (HNBR) and at least one secondary polymer, which is at least one of paraffin wax, low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE), and a plastomer. The base polymer and the at least one secondary polymer are blended into a polymer matrix. The elastomer alloy also includes a plurality of smart fillers dispersed within the polymer matrix, at least one chemical foaming agent, and a curing activator.

Various cables for cable deployed electric submersible pumping systems and methods of manufacturing such cables are provided. The cable includes a power cable core and coiled tubing formed around the power cable core. The power cable core includes one or more conductors, insulation surrounding each conductor, and an elastomeric jacket extruded around the insulated conductors. Various mechanisms, systems, and methods are described to anchor the power cable core in the coiled tubing and to transfer weight from the power cable core to the coiled tubing.

A bore tool can include a component that includes a longitudinal axis and a perimeter surface disposed at one or more radii from the longitudinal axis; and an elastomeric component disposed about the perimeter surface where the elastomeric component includes an elastomeric material that includes carbon-based nanoplatelets.

A packer that is usable with a well includes a tubular inner core and a swellable body that is mounted to the core and is adapted to swell in the presence of a triggering agent to form an annular seal in the well. The swellable body longitudinally extends between first and second ends of the body and includes a first region that is located between the first and second ends of the swellable body to swell at a first rate and at least a second region that is located closer to one of the first and second ends than the first region to swell at a second rate less than the first rate.

Swellable packer

A swellable packer device upon exposure to brine in a well. The device may be swellable to a substantially constant profile in spite of significant fluctuations in brine concentrations. Thus, the likelihood of packer failure due to under-swelling or over-swelling is reduced. Indeed, the packer may be employed for long-term operations or isolations ranging from a couple of weeks to twenty years or more without undue concern over packer failure from under or over swelling.
