摘要： A production stream from a well formed in a subterranean formation is flowed to a gas oil separation unit. The gas oil separation unit includes a separator vessel. The production stream includes an emulsion including an oil phase and an aqueous phase. Steam is mixed with the production stream prior to the production stream entering the separator vessel. Phases of the production stream are separated by the separator vessel to produce a vapor stream, an aqueous stream, and an oil stream.

摘要： A method includes designing a lower completion string for a multi-stage hydraulic fracturing job for a wellbore drilled into a subterranean zone. The lower completion string includes a plurality of stages and a plurality of packers configured to isolate each of the stages. Each stage of the plurality of stages includes a respective tubular stage assembly, and each stage is configured to be placed within a respective one of a plurality of frac intervals of the wellbore defined by the plurality of packers. Designing the lower completion string includes, for each stage of the plurality of stages, receiving a measured hole diameter of the respective one of the plurality of frac intervals and performing an axial safety factor analysis of the stage. The axial safety factor analysis includes a comparison of a yield strength in tension or compression of the respective tubular stage assembly of the stage with calculated effective axial tensile or compressive forces to which the respective tubular stage assembly of the stage would be subject when positioned in the frac interval in the wellbore. The axial safety factor analysis uses a predicted anchored status of the lower completion string, which includes an extent to which the respective tubular stage assembly would be predicted to elongate or contract when the lower completion string is positioned in the wellbore and the plurality of packers are set. The axial safety factor analysis also uses a distance between a first packer of the plurality of packers isolating the stage and a second packer of the plurality of packers isolating the stage, and the measured hole diameter of the respective frac interval. The method also includes determining that the axial safety factor analysis for each stage of the plurality of stages satisfies a threshold and, in response to the determining that the threshold is satisfied for each stage of the plurality of stages, inserting the lower completion string into the wellbore and performing the multi-stage hydraulic fracturing job.

摘要： An unmanned aerial vehicle (UAV) configured to land, take off, and magnetically perch on a ferromagnetic cylindrical surface is provided. The UAV includes a body and articulated magnetic legs configured to land and magnetically perch the UAV on the cylindrical surface. Each magnetic leg has a fixed portion coupled to the body and a pivoting portion pivotably coupled to the fixed portion at a pivot axis. The pivoting portion includes a switchable magnet and a single articulation joint that provides the pivoting portion with a single degree of freedom about the pivot axis to passively orient the pivoting portion inward and tangent to the cylindrical surface in response to the pivoting portion contacting the cylindrical surface during the landing, and to passively maintain the inward orientation of the pivoting portion during the takeoff.

摘要： Systems and methods include a computer-implemented method for performing well placement and configuration. Two-dimensional (2D) target entry (TE) points are generated in an area of interest (AOI) for wells to be drilled in an oil reservoir, where the 2D TE points are positioned according to a defined well length resolution. A single lateral is designed for each well using the 2D TE points, where each single lateral is designed with a different length, completion zone, azimuth, and orientation. Using the single laterals, a dynamic reservoir simulation is executed for the wells to be drilled in the oil reservoir, including rotating between different three-dimensional (3D) configurations for each 2D TE. A 3D configuration for each 2D TE is selected for each lateral and based on executing the dynamic reservoir simulation.
