A system and method are provided for stimulating heterogeneous subterranean formations using a tailored particulate diverter (PD). In some embodiments, a wellbore completion string includes an inflow control device (ICD) positioned in a high-permeability zone and an additional completion section positioned in a lower-permeability zone. The ICD includes restrictive openings, such as nozzles or valves, configured to impose a predictable pressure drop to balance inflow during production. During stimulation, the tailored particulate diverter comprising degradable diverter particles suspended in a carrier fluid is pumped into the completion string. The diverter particles exhibit a multimodal particle size distribution with at least four distinct size modes selected to bridge and seal the restrictive openings of the ICD, diverting stimulation fluid into the lower-permeability zone. Following treatment, the diverter particles degrade under downhole conditions to restore flow through the restrictive openings, improving stimulation coverage and enhancing overall production and/or injection efficiency.

Methods and apparatus for treating fluid streams containing solids are described herein. One method includes mixing a fluid stream containing solids, or a material derived from the fluid stream containing solids, with a flocculant agent, a coagulant agent, or both to form a mixture; routing the mixture to a high efficiency separator to yield a solids stream and a liquid stream; and routing the solids stream to an electro-osmotic filter press to form a solid filter cake. The fluid stream can be a water-based stream or a non-aqueous stream.

A downhole drilling tool, forming part of a subterranean drilling system, may include at least one plate secured to an exterior of an elongate body. Electronics may be disposed between the plate and the body to be protected by the plate while still readily accessible. A dynamic element may be radially extendable from the plate to engage an inner wall of a borehole being drilled. If this radially-extendable element becomes worn or damaged from this engagement, the plate may be replaced. More expensive components of the drilling tool may be contained within the elongate body, rather than the plate, thus reducing replacement frequency. Additionally, plates including unique features may be employed at different times without altering the underlying elongate body.

A breakover management system may monitor, with a monitoring frequency, a rig sensor data stream to identify a rig state of the drill rig, the rig sensor data stream having a measurement frequency greater than the monitoring frequency. A breakover management system may store the rig sensor data stream in a cache for a cache period. A breakover management system may, when the rig state includes a movement state after a static state, retrieve the rig sensor data stream from a cache for the cache period. A breakover management system may identify, based on an analysis frequency of the rig sensor data stream, a breakover profile of a breakover event experienced by the drill rig, the analysis frequency greater than the monitoring frequency.

Methods and systems for managing enhanced geothermal system fields are provided. The fields may be managed by monitoring the fields using both point and distributed sensors. Measurements from the sensors may be used to model the fields, and potential scenarios for the fields. The measurements may also be used to revise the models for the fields, such as corrections of incorrect assumptions regarding the fields. The models may also be used to proactively alert and/or take automated actions to address occurrence of undesired events in the fields.

A method for operating a system for in-situ mining in a rock formation in an area of interest includes: receiving a lixiviant at a first well extending downward, injecting the lixiviant into a permeable layer of the rock formation via the first well to dissolve a target material to form a solution containing the lixiviant and the target material, and applying an electric field to at least one of the lixiviant or the solution by the first well as a first electrode and a second well as a second electrode, receiving the solution via the second well extending downward, and pumping the solution, via the second well, to a processing plant to separate the target material from the lixiviant, wherein one or both of the injecting the lixiviant or the applying the electric field are changed according to a timing sequence during an operational period of the in-situ mining.

A rotary steerable system including a plurality of extendable pads deployed in a drill collar. Each of the pads is configured to extend radially outward from the drill collar and engage a wellbore wall and steer a direction of drilling. A plurality of digital valves is in fluid communication with corresponding ones of the plurality of extendable pads such that opening one of the plurality of digital valves provides high pressure drilling fluid to the corresponding pad thereby radially extending the pad. An electronic control unit deployed in a roll-isolated housing is configured to independently open and close each of the plurality of digital valves via a communications signal.
