Abstract: Fracturing slurries are prepared on the fly using a solids pump to feed the solid such as a gel into a liquid stream of normally water for pumping downhole with a large capacity triplex pump. The solids pump is preferably a Posimetric® style which delivers the solid into the fluid pipeline in a manner that keeps fluid from backing into the solids hopper above the solids pump. A separate fluid tank is connected to a fluid pump to pressurize a suction line to a boost pump before reaching the triplex pump and pumping into the subterranean formation. The solids pump can deliver between the fluid and boost pumps in which case the solids go through the triplex pump or alternatively the solids can be delivered into the higher pressure discharge line of the triplex pump.

Abstract: In a completion for producing methane the bottom hole assembly has a base pipe with porous media surrounding it for equalizing flow along the base pipe. A shape memory polymer foam surrounds the porous media. The borehole can be reamed to reduce produced methane velocities. Surrounding the shape memory polymer is an exterior layer of consolidated proppant or sand that can self-adhere and/or stick to the polymer foam. The proppant or sand can be circulated or squeezed into position although, circulation is preferred. The borehole may enlarge due to shifting sands in an unconsolidated formation as the methane is produced. The bottom hole assembly helps in fluid flow equalization and protects the foam and layers below from high fluid velocities during production.

Abstract: A method for recovering subsurface hydrocarbons, including heavy oil or bitumen, wherein a downhole steam injection phase is followed by application of heat to the near-wellbore region of the reservoir, heat being applied only during periods without steam injection. The heat application can be achieved by any number of techniques including electrical heaters, radio frequency waves, electromagnetic waves and microwaves. Numerous advantages are possible by withholding heat application during the steam injection phase. While preferred for use with cyclic steam stimulation recovery techniques, the method can be applied with other steam-based recovery techniques.
