Abstract in simplified Chinese:一种方法与设备,其系用于由在一延迟炼焦单元中所生产的一闪气区气态油流移除微粒物质。本发明之方法与设备使用气旋分离,以由闪气区气态油流移除微粒物质。该油流能够接受进一步处理,例如借由将油流通至一固定床催化氢化应单元,并接着通至一流体化床催化裂解单元,或是通至其他的处理单元,从而增强闪气区气态油流的价值。
Abstract:
A method of fracturing a reservoir wherein the main fracture stimulation treatment is preceded by depositing non dissolving solids into fracture tips where excessive downward or upward fracture growth is not desired, thereby controlling fracture geometry. The method thereby increases production of a fluid, such as water, oil or gas, from said reservoir, and avoids fracture propagation out of the pay-zone into undesirable zones.
Abstract:
A uniform oleophobic or oleo- and hydrophobic film is applied to equipment used in the petroleum industry. The methods can be applied to new equipment or equipment pulled from service, with the application process being performed in a controlled environment or the field. Applicator tools for efficient delivery and application of cleaners, solvents, and films used in the coating process are also described.
Abstract:
Systems and methods compute dysfunctions via mapping of tri-axial accelerations of drill pipe into drill-string motions. The methods remove gravitational and centripetal accelerations to yield corrected acceleration data due to the vibration only, transform the corrected acceleration data, and maps resulting transformed acceleration data into continuous drill-string positions. The maps provide 2D/3D visualization of drill-string motions to enable real-time optimization and control of well drilling operations and other scenarios where proactive detection of temporal events in automated systems may aid in avoiding failures.
Abstract:
Producing hydrocarbons by steam assisted gravity drainage, more particularly, utilizing conventional horizontal wellpair configuration of SAGD in conjunction of infill production well, to coinject oil-based solvents with steam initially and then switch to NCG-steam coinjection after establishing thermal communication between the thermal chamber and infill well.
Abstract:
Implementations described and claimed herein provide systems and methods for isolation detection. In one implementation, an axial acoustic signal is obtained. The axial acoustic signal is captured using an axial sensor deployed in a structure in a subterranean surface. The axial acoustic signal is separated into a first wave region and a second wave region by applying velocity filtering. An axial symmetry of a portion of the structure is determined based on at least one of the first wave region or the second wave region.
Abstract:
THE INVENTION IS DIRECTED TO STABLE CROSSLINKED WATER-SOLUBLE SWELLABLE POLYMERS AND METHODS FOR MAKING SAME. MORE PARTICULARLY, THE INVENTION RELATES TO A COMPOSITION COMPRISING EXPANDABLE POLYMERIC PARTICLES HAVING ANIONIC SITES AND LABILE CROSSLINKERS AND STABLE CROSSLINKERS, SAID PARTICLE MIXED WITH A FLUID AND A CATIONIC CROSSLINKER THAT IS CAPABLE OF FURTHER CROSSLINKING THE PARTICLE ON DEGRADATION OF THE LABILE CROSSLINKER AND EXPOSURE OF THE ANIONIC SITES SO AS TO FORM A GEL. 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 PH OF THE TARGET ZONE CAUSE DEGRADATION OF THE LABILE CROSSLINKER AND THE PARTICLE EXPANDS, THE CATIONIC CROSSLINKER CROSSLINKS THE POLYMER TO FORM A GEL, THUS DIVERTING WATER TO LOWER PERMEABILITY REGIONS AND IMPROVING OIL RECOVERY. NO SUITABLE
Abstract:
The invention is directed to delayed gelation agents comprising a degradable polymeric cage containing therein one or more gelation agents. The cage degrades in situ, e.g, in an oil reservoir, thus releasing the gelation agent(s), which can then crosslink second polymers in situ to form a gel.
