Abstract: The disclosure relates to an electrocrushing drilling fluid with an electrocrushing drilling base fluid including a non-polar oil, water, and glycerin. The base fluid may further include a polar oil and an alkylene carbonate. The electrocrushing drilling fluid may further contain at least one additive. The electrocrushing drilling fluid may have a dielectric constant or dielectric strength of at least a set amount, an electric conductivity less than a set amount, or a combination of these properties. The disclosure further relates to an electrocrushing drilling system containing the electrocrushing drilling fluid and an electrocrushing drill bit.

Abstract: A set of alarm criteria for a drilling tool may be obtained. Individual alarm criterion of the set of alarm criteria may be satisfied based on the drilling tool operating with a set of operating characteristics corresponding to the individual alarm criterion. The set of alarm criteria may include two or more of a tight-hole alarm criterion, a washout alarm criterion, a packoff alarm criterion, a weight-stacking alarm criterion, a delta-torque alarm criterion, a torque alarm criterion, a rate-of-penetration alarm criterion, a reamer-tension-compression alarm criterion, a running-speed alarm criterion, a drag alarm criterion, and/or a pipe-movement alarm criterion. An alarm event corresponding to an alarm criterion may be detected based on the operating characteristic(s) of the drilling tool matching the set of operating characteristics corresponding to the alarm criterion. Responsive to detection of the alarm event, an alarm for the alarm event may be generated.

Abstract: A method is described for seismic imaging that may include receiving digital seismic data; processing the digital seismic data to create a digital seismic image in a seismic domain; flattening the digital seismic image to generate a digital flattened image; identifying artifacts in the digital flattened image; transforming the artifacts back into the seismic domain; and reprocessing the digital seismic data based on the artifacts in the seismic domain to generate a digital image with reduced artifacts. The method may be executed by a computer system.

Abstract: Described herein are various embodiments of computer-implemented methods, computing systems, and program products for analyzing a flood operation on a hydrocarbon reservoir. For example, an embodiment includes establishing a dataset of allowed well connections for at least one production well and at least one injection well of the hydrocarbon reservoir. The embodiment includes iteratively modifying the dataset of allowed well connections based on a distance category, a static features category, a dynamic features category, or any combination thereof, where the static features category uses static data of the hydrocarbon reservoir and the dynamic features category uses dynamic data of the hydrocarbon reservoir. The embodiment includes, after iteratively modifying the dataset of allowed well connections, running capacitance resistance modeling using the modified dataset of allowed well connections as an input.

Abstract: A graphical user interface may provide visualization of comparison between planned value(s) and usage value(s) of a set of operating parameters for a tool. The graphical user interface may include a planned usage region and a usage region. The planned usage region may provide visualization of the planned value(s) for the tool. The usage region may provide visualization of the usage value(s) for the tool. The usage region may include a compliance section. The compliance section may provide visualization of whether the usage value(s) complies with the corresponding planned value(s) such that the compliance section includes different visual features based on whether the usage value(s) complies or does not comply with the corresponding planned value(s). The usage region may provide comments and/or recommendations based on the learnings from analysis of offset wells.

Abstract: Described herein are various embodiments of computer-implemented methods, computing systems, and program products for analyzing a flood operation on a hydrocarbon reservoir. An embodiment of a computer implemented method of identifying conformance candidates is provided. The embodiment includes, for a first entity: solving an injection entity index to generate an injection entity index value, solving a production entity index to generate a production entity index value, evaluating an operation entity index that represents operation status to generate an operation entity index value, and combining the injection entity index value, the production entity index value, and the operation entity index value to generate a conformance problem index value for the first entity.

Abstract: A geometric method is described for 3D structural restoration of a subsurface model including receiving data representative of a subsurface volume of interest including one or more chronohorizons and the geometry and topology of any faults of relevance; developing a fault framework model of the subsurface volume of interest; selecting a horizon, the deposition of which represents the geologic time to which the structural model should be restored; developing coordinate transformation constrained by a single datum horizon and, optionally, additional geologic constraints; applying the 3D transformation to all geologic features below and, optionally, above the datum surface; and scaling the vertical coordinates to accurately relate vertical and horizontal dimensions. The method may be executed by a computer system.
