Abstract: The invention relates generally to a method for supporting non-buoyant offshore drilling units that are anchored to the sea floor and are subject to heavy lateral loads. Specifically, tension tendons are attached to piled foundations to prevent jack-ups from being overturned by the loads. Tension can also be applied to the tendons to provide additional hold down forces to the offshore units.

Abstract: The present invention relates to a novel method of maintaining a steady and/or proper water-gas ratio for the wet in situ combustion process for oil recovery. In particular, the method comprises mixing water with a foaming agent, or some other colloid capable of generating foam, in addition to gas. The foam carries the water through heated reservoirs more efficiently and prevents separation from the gas. As such, more heat can be scavenged, thus an increased amount of steam is generated and transferred to the oil to increase its recovery.

Abstract: Systems and methods generate steam in hydrocarbon recovery operations and may further enable emulsion separation and product upgrading. The methods rely on indirect boiling of water by contact with a thermal transfer liquid heated to a temperature sufficient to vaporize the water. Examples of the liquid include oils, recovered hydrocarbons, liquid metals and brine. Heating of the liquid may utilize circulation of the liquid across or through a furnace, heat exchangers, or a gas-liquid contactor supplied with hot gas. Further, a solvent for bitumen introduced into the water may also vaporize upon contact with the thermal transfer liquid.

Abstract: A steam-assisted gravity drainage method includes a two stage solvent injection scheme, wherein steam plus solvent injection is followed by steam plus heavier-solvent injection. The two solvent injections improve recoveries of both the heavy oil and the injected solvent while limiting steam requirements, thus improving the economics of the method.

Abstract: Refracted energy travel time can help to derive anisotropic parameters in a target layer. These anisotropic parameters allow us to both explore for new reservoirs and to understand stress and fracturing in existing reservoirs. This information can be used to i) detect oil reservoirs, ii) spot naturally fractured, hence high production zones, iii) detect dominant natural stress directions, iv) better place horizontal wells to optimize production, v) monitoring man made fractures or induced directional stress changes. The method is demonstrated using synthetic and real data.

Abstract: The invention is directed to stable crosslinked water-soluble swellable polymers, methods for making same, and their various uses in the hygiene and medical arts, gel electrophoresis, packaging, agriculture, the cable industry, information technology, in the food industry, papermaking, use as flocculation aids, and the like. More particularly, the invention relates to a composition comprising expandable polymeric microparticles having labile crosslinkers and stable crosslinkers, said microparticle mixed with a fluid and an unreacted tertiary crosslinker that is capable of further crosslinking the microparticle on degradation of the labile crosslinker so as to form a stable gel. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric particles are injected into a well and when the heat and/or pH of the well cause degradation of the labile crosslinker and when the particle expands, the tertiary crosslinker crosslinks the polymer to form a stable gel, thus diverting water to lower permeability regions and improving oil recovery.

Abstract: The invention is an electric powered mechanism for lifting and lowering at the wheels for an electric sweep type seismic vibrator source of the type used in seismic prospecting for hydrocarbons. The source uses an engine and generator combination to create electric power for all systems on the source such as driving a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion along with driving the source from location to location through a survey area. Preferably a foot is arranged on the bottom end of the rod or piston for contact with the ground and by engaging the grid of motors to push down against the ground in a rapid progression, acoustic energy is created and delivered into the ground for geophones to sense and record. The electric powered wheel mechanism may be utilized to bring the foot of the rod or piston in contact with the ground or in closer proximity to the ground or level the source prior to emitting the seismic energy or to adjust weight on the acoustic energy delivery system while seismic energy is being delivered.
