Abstract: The invention is an electric power accumulator used with 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 to drive a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion. The source may also be designed to use electric power to drive the source from location to location through a survey area. A large electric power accumulator is provided to store electric power when the generator is able to produce excess power and the accumulator may deliver power along with the generator to drive the rods and deliver acoustic energy. With a large electric power accumulator, such as a battery or capacitor, the engine and generator combination may be engineered to be somewhat smaller, less costly and more efficient than a system where the engine and generator were sized to provide the electric power at times of maximum electric draw.

Abstract: A subsea facility for hydrocarbon recovery in deep waters and methods of installation are provided. More specifically, the subsea facility equipment is on multiple modules equipped with a buoyancy system to allow the modules to sink to the sea floor. The modules can be attached and unattached to each other, thus allowing for a module to be raised to the surface for repairs without affecting the rest of the subsea facility.

Abstract: The illumination/imaging of a theorized target horizon that is below a theorized velocity contrast horizon where the velocity contrast horizon may represent the bottom of a salt dome by assessing the path of seismic energy for critical angle reflection/refraction and tabulates the successful paths and unsuccessful paths. For some subsurface locations, seismic energy will not reach the surface above the velocity contrast due to the shapes of the velocity contrast horizon and target horizon and the velocity model through which the studied waves propagate. Displays may be prepared and used for understanding illumination/imaging of the geology for drilling, reacquisition, and reprocessing to elicit information about subsurface geology that may have been overlooked or ignored. Future surveys avoid expensive surveying which cannot obtain useful seismic data as determined by the velocity contrast for the target locations due to the shapes of the horizons and the velocity model.

Abstract: The invention relates to processing seismic data that includes signals from at least two sources and typically three or four sources where source separation is necessary for geophysical analysis. Specifically, the present invention is an analytical technique that quickly creates a more accurate source signature delivered by analysis of the source generated data contamination present in the separated data. The technique is to invert a segment of the data using a seed source signature and compute an error that reflects the generated data contamination observed in the separated source data. The source signature is iteratively revised as the segment is continually inverted with the goal of finding the optimal source signature that provides the lowest computed error. The source signature that provides the lowest error is, or is very close to, the true source signature and is then used in the separation process for the entire composite data set. This will provide much more information for geophysical interpretation.

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.

Abstract: A method for creating a modified realization of a geostatistical model of a subterranean hydrocarbon reservoir is described, which may be used in a history matching process. The modified realization is based on a current realization which is a function of a first uniform random number field. At least one further uniform random number field Ui is created and a linear combination made of the first uniform random number field and the further uniform random number field or fields Ui, together with combination coefficients ri, to derive a modified non-uniform random number field V. A uniform score transformation procedure is then performed, e.g. using an empirical cumulative distribution function, on the modified non-uniform number field V, to derive a modified uniform random number field Umod. A modified realization of the model can then be derived from the uniform random number field Umod.

Abstract: Steam is generated using high total dissolved solids (TDS) boiler feedwater while still maintaining relatively low boiler blowdown rates. In one embodiment, a boiler is adapted to generate low quality steam from the high TDS feedwater to maintain wet conditions in the boiler tubes to mitigate against fouling/scaling problems. The low quality steam is then separated into a vapor fraction and a liquid blowdown stream. The vapor fraction is superheated to superheated steam. The liquid blowdown stream is allowed to exchange heat with the thus-created superheated steam to vaporize a portion of the blowdown to form a finished steam and a waste stream. This reduces the blowdown to waste and creates more end user steam. The finished steam is routed to its end use, e.g., a hydrocarbon thermal recovery process. Advantages include lower cost, higher efficiency, and less equipment complexity.
