Abstract: A power system includes a power source, field gas supply, and natural gas supply, and is operable using a gas mixture comprising field gas from the field gas supply and natural gas from the natural gas supply. A ratio of field gas to natural gas is adjusted based on sensed property of the field and/or natural gas, change in a condition of the field and/or natural gas, measured emissions from the power source, predicted emissions from the power source, and/or direct/indirect feedback from the power source. A method for operating a power system includes: connecting a mixing gas line and a field gas line to a power source at work site; determining a ratio of mixing gas to field gas; combining mixing gas from the mixing gas line and field gas from the field gas line based on the determined ratio; and operating the power source with the combined gases.

Abstract: Methods for determining parameter/s of a well completion design (WCD) for at least a portion of a drilled well based on drilling data corresponding to variables of mechanical specific energy (MSE) are provided. In some cases, MSE values may be acquired and the WCD parameter/s may be based on the MSE values. The MSE values may be obtained from a provider or may be acquired by calculating the MSE values via the drilling data. In some cases, the data may be amended prior to determining the WCD parameter/s to substantially neutralize distortions of the data. In some cases, the methods may include creating a geomechanical model of the drilled well from acquired MSE values, optionally amending the geomechanical model and determining the WCD parameter/s from the geomechanical model. Storage mediums having program instructions which are executable by a processor for performing any steps of the methods are also provided.

Abstract: A method for optimizing pressure exchange includes providing a first pressure exchange system comprising an energy recovery device (ERD). A second system supplies high-pressure fluid, energized by a positive displacement pump, to the ERD. A third system supplies low-pressure fluid to the ERD. The first system energizes the low-pressure fluid with the high-pressure fluid to form a high-pressure fracking fluid, which is delivered from the first system to a well-head. A rate of required flow is input into a control system, which determines a rate of flow of the high-pressure fluid, a rate of flow of the low-pressure fluid, and an actual rate of flow of the fracking fluid at the well-head. The control system then adjusts to equilibrium: the rate of flow of the high-pressure fluid based on the actual rate of flow; and the rate of flow of the low-pressure fluid based on the actual rate of flow.

Abstract: Compositions and methods are provided for plugging a fracture network in a wellbore. Exemplary compositions comprise a mixture of particles, some of the particles being degradable and other particles being elongated, having good compressive strength, and not being readily degradable at the conditions of the formation. The mixture of particles can temporarily bridge or plug fractures within the formation, and thus acts as a temporary diversion agent. After the degradable particles dissolve, the particles which are not readily degradable can remain in the fracture, helping to keep the fracture open and acting as a proppant.
