Abstract
The present disclosure describes methods and systems, including computer-implemented methods, computer program products, and computer systems, for determining a mudweight of drilling fluids in a hydrocarbon reservoir. One computer-implemented method includes: receiving pore pressure data of a rock formation in the hydrocarbon reservoir; determining permeability data of fractures of the hydrocarbon reservoir; determining Hoek-Brown failure criterion data; and determining a safe mudweight window based on the pore pressure data of the rock formation, the permeability data of the fractures, and the Hoek-Brown failure criterion data.
Claims20
A computer-implemented method for determining a mudweight of drilling fluids in a hydrocarbon reservoir, comprising:
- receiving, by a hardware processor, pore pressure data of a rock formation in the hydrocarbon reservoir;
- determining, by the hardware processor, permeability data of fractures of the hydrocarbon reservoir;
- determining, by the hardware processor, Hoek-Brown failure criterion data;
- and
- determining, by the hardware processor, a safe mudweight window based on the pore pressure data of the rock formation, the permeability data of the fractures, and the Hoek-Brown failure criterion data.
A non-transitory computer-readable medium storing instructions which, when executed, cause a computer to perform operations comprising:
- receiving, by a hardware processor, pore pressure data of a rock formation in a hydrocarbon reservoir;
- determining, by the hardware processor, permeability data of fractures of the hydrocarbon reservoir;
- determining, by the hardware processor, Hoek-Brown failure criterion data;
- and
- determining, by the hardware processor, a safe mudweight window based on the pore pressure data of the rock formation, the permeability data of the fractures, and the Hoek-Brown failure criterion data.
A device, comprising:
- at least one hardware processor;
- and
- a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions, when executed, cause the at least one hardware processor to perform operations comprising:
- receiving pore pressure data of a rock formation in a hydrocarbon reservoir;
- determining permeability data of fractures of the hydrocarbon reservoir;
- determining Hoek-Brown failure criterion data;
- and
- determining a safe mudweight window based on the pore pressure data of the rock formation, the permeability data of the fractures, and the Hoek-Brown failure criterion data.
