  • Patent number: 11885208
    Abstract: A method of controlling a pumping stage of a fracturing fleet at a wellsite with a set of electric frac pumps to deliver fracturing fluids into a target formation at a steady pressure value. An global control process on a computer system communicatively connected to the plurality of pumping units can communicate a unit setpoint to each pumping unit, monitor the sensor measurements, compare the periodic datasets to a target pressure, and modify the fluid output of the pump units to achieve the target pressure during the pumping operation. The global control process can direct at least one pumping unit to deliver a fracturing treatment at a pressure higher or lower than the target pressure in response to changing wellbore environment pressures.

  • Patent number: 11885205
    Abstract: Systems and methods for predicting a breakdown pressure of a formation and fracturing the formation account for filter cake effects. The systems and methods measure a time-dependent permeability and a time-dependent thickness of a filter cake formed by a first drilling mud. The systems and methods determine a time-dependent permeability model and a time-dependent thickness model of the filter cake. The systems and methods select a breakdown pressure model based on (i) the time-dependent thickness of the filter cake, (ii) the time-dependent permeability of the filter cake, and (iii) the permeability of the formation. The systems and methods use the selected breakdown pressure model to predict the breakdown pressure of the formation and fracture the formation using a drilling fluid having a mud weight associated with the predicted breakdown pressure of the formation.

  • Patent number: 11859479
    Abstract: A method for quantifying frac hits within a few days using a novel pressure-transient analysis technique called differential pressure-transient analysis (DPTA). Unlike pressure transient analysis (PTA) methods, focused on single-well analyses, DPTA evaluates pressure response from two or more wells simultaneously to (1) determine the existence of frac hits, and (2) determine the magnitude of interference, defined as the ratio of inter-connected to total number of primary fractures from a given well. The output from (2) can be subsequently used to accurately predict oil and/or gas production rates for infill and offset wells.
