Abstract: In some examples, a system includes a stress field assessment engine, implemented by at least one processor, to determine stress distribution and yield state data based on a geomechanical model, and a natural fracture determination engine, implemented by the at least one processor, to generate a natural fracture network model based on the stress distribution and yield state data. The system may implement a method that includes generating a geomechanical model of a subsurface formation, where the geomechanical model includes a formation model and a wellbore model, simulating the geomechanical model to determine stress distributions and yield states in the subsurface formation, and generating a natural fracture network model using a machine learning technique on the stress distributions and yield states.

Abstract: A hybrid machine includes an engine, a first and second motor, a first and second generator, and a first and second geartrain. The engine generates power from a combustion reaction and includes an intake port, a combustion chamber, a piston, a crankshaft, and an exhaust port. The intake port receives air from an external environment. The combustion chamber mixes the air with fuel to create a mixture that is ignited. The piston actuates to rotate the crankshaft. The exhaust port delivers exhaust gases out of the engine. The first and second motors respectively include a first and second hub that rotate from supplied power. The first and second generators respectively generate power when a first and second shaft rotate. A first and second geartrain respectively connect to the first and second motors, the first and second generators, and the crankshaft to transmit power to a first and second wheel.

Abstract: A method for monitoring waterfront movement in a subsurface formation involves performing forward modeling of at least one deep electromagnetic survey of the waterfront movement, and determining locations for installing an electrically insulating spacer between well liners to form an on-demand electromagnetic source electrode. Based on the forward modeling, repeat survey time intervals are predicted. The method involves, during well completion, installing the electrically insulating spacer between the well liners in a reservoir to form at least one on-demand electromagnetic source electrode, and installing the electrically insulating spacer between the plurality of well liners in a reservoir to form an on-demand electromagnetic receiver electrode. A waterfront survey is performed by conveying a production logging tool into a well that temporarily converts the well liners into an on-demand electromagnetic source electrode and an on-demand receiver electrode, and inverse modeling of the waterfront survey is performed to produce a water saturation image.

Abstract: A method involves obtaining a measured drainage function for a well and obtaining a set of drainage models, wherein each drainage model includes a reservoir model and a fracture model. The method also includes, for each drainage model, forming a predicted drainage function based, at least in part, on the drainage model, and determining a misfit value based, at least in part, on the predicted drainage function and the measured drainage function. The method further includes determining a set of candidate drainage models based, at least in part, on the misfit value for each drainage model, wherein each candidate drainage model comprises a candidate reservoir model and a candidate fracture model.

Abstract: Well treatment fluids may include solid particles comprising one or more components selected from the group consisting of urea, ammonium nitrate, ammonium chloride, barium hydroxide, and ammonium thiocyanate. These well treatment fluids may also include a carrier fluid, which may be an aqueous polymeric fluid, an oil, or combinations thereof. The aqueous polymeric fluid may include a polymer selected from the group consisting of guar gum, hydroxypropyl guar, carboxymethyl hydroxypropyl guar, cellulose, or polyacrylamide. The oil may include a material selected from the group consisting of diesel, mineral oil, and wax. Methods for reducing an acid carbonate reaction in a carbonate formation may include pumping a composition of solid particles into a formation; releasing the solid particles from the capsules or emulsion within the formation; and injecting an acid following the releasing step or during pumping, wherein the acid carbonate reaction is carried out at a reduced reaction rate.

Abstract: A method for monitoring gas production in a subterranean formation includes introducing a polymer composite particle having a degradable portion and a non-degradable portion including a tracer into a stimulation fluid and injecting the stimulation fluid into the subterranean formation to a treatment stage of a treatment zone. The treatment stage has at least one opening that the polymer composite particle may flow into and remain inside. The polymer composite particle may be exposed to moisture at a downhole temperature while inside the at least one opening. The moisture may degrade the degradable portion of the polymer composite particle, thereby releasing the non-degradable portion including the tracer. Produced gas that includes the non-degradable portion including the tracer may be recovered from the subterranean formation and the tracer may be correlated to the treatment stage of the treatment zone of the subterranean formation.
