  • Method for estimation of fluid storage capacity of rock samples and other porous materials under effective stress
    Patent number: 11674876
    Abstract: The system includes a gas tank. A reference volume is fluidly coupled to the gas tank. A coreholder fluidly is coupled to the reference volume. A sample is disposed in the coreholder. A fluid pump is fluidly coupled to the coreholder. A first pressure transducer is fluidly coupled between the fluid pump and the coreholder. The first pressure transducer measures a confining pressure. A second pressure transducer is fluidly coupled to the coreholder. The second pressure transducer measures upstream pressure within the coreholder.

  • Evaluating stress-dependent permeability in unsteady-state conditions and/or quality of microproppant placement in subterranean formations
    Patent number: 10677707
    Abstract: Systems and methods for evaluating permeability at unsteady-state pressure conditions and areal distribution of microproppants are provided. In some embodiments, the methods comprise: obtaining a first dataset relating to a positive permeability through a split core plug sample of a subterranean formation at a plurality of different differential pressures; obtaining a second dataset relating to a positive permeability through the split core plug sample at each different differential pressure after a plurality of microproppant particles have been placed between two halves of the sample; extrapolating a baseline positive permeability of the sample at a differential pressure equal to zero based on the first dataset; extrapolating a treated positive permeability of the sample at a differential pressure equal to zero based on the second dataset; calculating a closure resistance of the fracture and the fracture closure pressure using the second dataset; and estimating a proppant areal placement factor.
