Abstract: Methods and systems relate to generating steam from water that may be recycled in thermal oil recovery processes and is heated in tubes having non-obtrusive features to limit fouling formation. The tubes may include jets to generate enhanced flow mixing along an inner wall of the tubes in order to increase heat transfer and disrupt bubble nucleation. Employing the tubes with the inner wall having an average surface roughness of less than one micron may further facilitate disruption of the bubble nucleation.

Abstract: The invention is directed to stable crosslinked swellable fluorescently tagged polymeric microparticles, methods for making same, and their various uses. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric particles are injected into target zone and when the heat and/or suitable pH of the target zone cause degradation of the labile crosslinker and the microparticles expand. The swelled polymer diverts water to lower permeability regions and improves oil recovery. The tags allow monitoring of the presence and concentration of the tagged microparticles and ultimately allow evaluation of the performance of such treatments. Detection of polymeric microparticles in producing wells can be instructive for teaching about the character and extent of thief zones in the subsurface. Better knowledge of the reservoir flow will enable improved application of the gel treatments, improved oil recovery, and allow improved forecasting using simulation modeling.

Abstract: Methods and systems produce petroleum products from a formation by a steam assisted process followed by an in situ combustion process. The steam assisted process utilizes an injector and first producer to form a steam chamber within the formation as the products are recovered. The in situ combustion then starts by injecting an oxidant into the formation and ignition of residual products. A combustion front advances toward a second producer that may be offset in a lateral direction from the first producer. Heat and pressure from the in situ combustion sweeps the products ahead of the combustion front to the second producer for recovery.

Abstract: Methods and systems relate to recovering hydrocarbons from within formations in which hydrocarbon bearing reservoirs are separated from one another by a fluid flow obstructing natural stratum. Relative to the reservoirs, the stratum inhibits or blocks vertical fluid flow within the formation. Lateral bores divert from lengths of injector and producer wells along where extending in a horizontal direction. These bores pass upward through the formation to intersect the stratum and provide an array of fluid flow paths through the stratum. In a side direction perpendicular to the horizontal direction of the wells, the lateral bores from the injector well pass through the stratum inside of where the lateral bores from the producer well pass through stratum. Fluid communication established by the bores limits counter-current flow through the bores in processes that rely on techniques such as gravity drainage.

Abstract: The invention is 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.

Abstract: The invention relates to the development of an analytical model to predict the velocity of the continuously expanding front of the steam chamber in a steam assisted gravity drainage (SAGD) hydrocarbon production system. The developed analytical model has advantages over reservoir simulation tool in that it is very fast and can be easily calibrated with field observation well data before making good prediction. One field study shows that the developed model can achieve excellent prediction for a field SAGD performance. A better understanding of the size of the steam chamber and the velocity of the front should provide better time, cost and energy efficiency for the production of high viscosity hydrocarbons.
