摘要： A process for reducing the permeability to water of a thief zone of a porous and permeable subterranean petroleum reservoir includes injecting a composition comprising a dispersion of betainised crosslinked polymeric microparticles in an aqueous fluid down a well and into a thief zone. The betainised crosslinked polymeric microparticles have a transition temperature that is at or below the maximum temperature encountered in the thief zone and greater than the maximum temperature encountered in the well. The betainised crosslinked polymeric microparticles are solvated by water, expand in size and optionally aggregate in the thief zone when they encounter a temperature greater than the transition temperature so as to reduce the permeability of the thief zone to water.

摘要： Methods of drilling earth formations may involve removing a portion of an underlying earth formation utilizing cutting elements of an earth-boring drill bit. A rotational speed of the drill string may be sensed utilizing a first sensor. A rate of penetration of the drill string during advancement of the earth-boring drill bit may be sensed utilizing a second sensor. An instantaneous average depth of cut of cutting elements of the earth-boring drill bit may be determined utilizing a control unit to calculate the instantaneous average depth of cut based on a sensed rotational speed of the drill string and a sensed speed of advancement of the drill string. The weight on the earth-boring drill bit may be increased utilizing the drawworks when the instantaneous average depth of cut is less than the predetermined minimum depth of cut.

摘要： A method of detecting an event within a wellbore includes obtaining a sample data set, determining a plurality of frequency domain features of the sample data set, comparing the plurality of frequency domain features with an event signature, determining that the plurality of frequency domain features matches the thresholds, ranges, or both of the event signature, and determining the presence of the event within the wellbore based on determining that the plurality of frequency domain features match the thresholds, ranges, or both of the event signature. The sample data set is a sample of an acoustic signal originating within a wellbore including a fluid. The sample data set is representative of the acoustic signal across a frequency spectrum. The event signature includes a plurality of thresholds, ranges, or both corresponding to the plurality of frequency domain features.

摘要： Method of recovering oil from a subterranean oil-bearing reservoir by using an injection fluid containing a viscosifying polymer in a low salinity water. The low salinity water has a total dissolved solids (TDS) content of 15,000 ppmv or less, and the ratio of the multivalent cation content of the low salinity water to the multivalent cation content of the connate water of the reservoir is less than 1. The viscosity of the injection fluid is in the range of 3 to 200 cP, and the reservoir is penetrated by one or more injection wells and by one or more production wells. The method includes injecting the injection fluid into at least one of the injection wells in a slug size in the range of 0.4 to 1.5 pore volume (PV).

摘要： A computer-implemented method for configuring operating conditions for at least one of desalination equipment and fluid injection equipment to be used in a low salinity waterflood on a hydrocarbon-bearing reservoir is provided. The reservoir is penetrable by an injection well and a production well. The method comprises deriving an ion diffusion distance value from: a diffusion coefficient indicative of a rate of diffusion of ions through relatively permeable layers of the reservoir when the low salinity water is present therein; and a residence time value indicative of the time required for the low salinity water to pass from the injection well to the production well through the reservoir; comparing the thickness of the relatively permeable layers to the derived ion diffusion distance value; generating an indication of the effectiveness of performing a low salinity waterflood; and configuring said operating conditions based on the indication of the effectiveness.

摘要： A free-standing riser system connects a subsea source to a surface structure. The system includes a concentric free-standing riser comprising inner and outer risers defining an annulus there between. A lower end of the riser is fluidly coupled to the subsea source through a lower riser assembly (LRA) and one or more subsea flexible conduits. An upper end of the riser is connected to a buoyancy assembly and the surface structure through an upper riser assembly (URA) and one or more upper flexible conduits, the riser also mechanically connected to a buoyancy assembly that applies upward tension to the riser. The riser may be insulated for flow assurance, either by a flow assurance fluid in the annulus, insulation of the outside of the outer riser, or both. The system may include a hydrate inhibition system and/or a subsea dispersant system. The surface structure may be dynamically positioned.

摘要： Multiple sensors on a drill string can be utilized to perform equivalent circulation density (ECD) analysis. By utilizing multiple ones of the sensors, the pressure drop in each section of the wellbore can be classified. Additionally, the inclusion of multiple sensors in the drill string allows a wellbore to be sectioned into intervals bounded by any two sensors. Pressure events occurring in a single section of the wellbore bounded by any two sensors can be isolated and analyzed. The isolation can be achieved by subtracting the pressure measured on the shallower sensor from that measured on the deeper sensor.
