    Abstract: Methods and systems for determining electrical characteristics of a subsurface formation are disclosed. The method may include installing a first electrically insulating spacer between well liners in the well to form an on-demand electromagnetic source electrode and installing a second electrically insulating spacer between well liners in the well to form an on-demand electromagnetic receiver electrode. The method may further include performing an electrical survey using the on-demand electromagnetic source and receiver electrodes, determining a map of the at least one electrical characteristic in a subsurface region surrounding on-demand electromagnetic source and receiver electrodes based on the electrical survey, determining a map of at least one formation property based on the map of the electrical characteristic, and updating a hydrocarbon reservoir production plan based on the map of at least one formation property.

    Abstract: A downhole system for multistage fracturing a subterranean formation that includes a first cluster of valves arranged on a tubular in an initially closed position. There is a second cluster of valves downhole of the first cluster, which is also arranged on the tubular in a respective initially closed position. The system has a plugging device operably coupled with a workstring, that is moved into the tubular. The plugging device is operable to move from a run-in configuration to a set configuration.

    Abstract: In some implementations, a controller may obtain an indication of a first crank angle associated with a first pump, of a dual-pump single-power source system, that is mechanically connected to a power source of the dual-pump single-power source system via a first clutch. The controller may obtain an indication of a second crank angle associated with a second pump, of the dual-pump single-power source system, that is mechanically connected to the power source via a second clutch. The controller may determine that a difference between the first crank angle and the second crank angle is outside of a tolerance of a crank angle difference value. The controller may modulate a fluid pressure associated with at least one of the first clutch or the second clutch to cause the difference between the first crank angle and the second crank angle to be within the tolerance of the crank angle difference value.

    Abstract: A method involves propagating hydraulic fractures in a reservoir. Such method includes creating a low pressure region in an attractor well. The attractor well is proximate to an area in which hydraulic fractures are desired. The method also includes initiating a hydraulic fracturing operation at a treatment well. The hydraulic fracturing operation is initiated so that a fracture network created by the hydraulic fracturing operation is drawn to propagate toward the low pressure region of the attractor well.
