Abstract: A sand handling system having, for example, one to three sand separators are configured to be operatively connected to a well and an inlet of a common dumping vessel. Advantageously, the dumping vessel has a sensor to measure an amount of sand in the dumping vessel and provide a signal to a programmable controller which is arranged to dump the dumping vessel when a specified amount of sand is in the dumping vessel. The system automates the sand handling process and also measures and records data associated with a number of flowback parameters. The data can then be used in well design to improve oil and/or gas production, lessen sand production, reduce well damage and/or equipment corrosion due to, for example, sand.

Abstract: Embodiments of the invention provide a “tool-kit” of processing techniques which can be employed in different combinations depending on the circumstances. For example, flow speed can be found using eddy tracking techniques, or by using speed of sound measurements. Moreover, composition can be found by using speed of sound measurements and also by looking for turning points in the k-w curves, particularly in stratified multi-phase flows. Different combinations of the embodiments can therefore be put together to provide further embodiments, to meet particular flow sensing requirements, both on the surface and downhole. Once the flow speed is known, then at least in the case of a single phase flow, the flow speed can be multiplied by the interior cross-sectional area of the pipe to obtain the flow rate. The mass flow rate can then be obtained if the density of the fluid is known, once the composition has been determined.

Abstract: Correlation matrices may be used to simultaneously correlate multiple wells. A correlation matrix may be generated for individual pairs of multiple wells. The values of elements of the correlation matrices may be determined based on matching between segments of the multiple wells and segments of one or more computational stratigraphic models. An N-dimensional space including an axis for individual wells may be generated. Directed walk may be performed within the N-dimensional space to generate paths representing scenarios of correlations for segments of the multiple wells.

Abstract: A hydrocracking catalyst comprising a zeolite beta having an average domain size from 800 to 1500 nm2; a zeolite USY; a catalyst support; and at least one metal selected from the group consisting of elements from Group 6 and Groups 8 through 10 of the Periodic Table. The zeolite beta has an OD acidity of 20 to 50 μmol/g and the catalyst support comprises an amorphous silica aluminate and a second support material when the weight percentage content of the zeolite beta is less than the weight percentage of the zeolite USY, and, when the weight percentage content of the zeolite beta is greater than the weight percentage of the zeolite USY, the zeolite beta has an OD acidity of 20 to 400 μmol/g, the zeolite beta content is from 0.5 to 10 wt. % and the zeolite USY has an ASDI between 0.05 and 0.12 with a corresponding zeolite USY content of from 0 to 5 wt. %. A process for hydrocracking a hydrocarbonaceous feedstock using the catalyst is also described as is a method for making the hydrocracking catalyst.

Abstract: A system for transferring at least one subterranean core sample under pressure can include a retrieval vessel that collects and houses the at least one subterranean core sample at a sampling pressure at which the at least one subterranean core is collected. The system can also include a linear actuator that couples to the retrieval vessel through a valve in the open position at a first time, where the linear actuator facilitates removal of at least one pressure barrier from the retrieval vessel through the valve at the first time while maintaining the sampling pressure of the at least one subterranean sample. The system can further include a testing vessel that couples to the linear actuator through the valve in the open position at a second time, and a hydraulic device that facilitates pressurizing the testing vessel to the sampling pressure at the second time.

Abstract: One embodiment includes receiving seismic data from a plurality of seismic sensors located proximate to a build section of a wellbore that is drilled into a subsurface. The seismic data is recorded for a plurality of seismic waves, at different angles, sent from a plurality of seismic sources towards the plurality of seismic sensors. Locations of the plurality of seismic sources relative to locations of the plurality of seismic sensors are such that the plurality of seismic waves are essentially planar at the plurality of seismic sensors. The subsurface is essentially homogenous proximate to the build section. For at least a portion of the plurality of seismic waves, the embodiment includes determining a slowness vector for each seismic wave, and determining a phase velocity and a phase angle. The embodiment includes determining at least one anisotropic parameter value for the build section, determining a vertical velocity value, and using these.
