摘要： A method for performing an oilfield operation at a wellsite having a drilling rig configured to advance a drilling tool into a subsurface formation. The method includes generating a borehole temperature model for an area of interest using water depth information and a vertical stress model, generating a formation temperature model using the borehole temperature model, generating a mud-weight pressure model using the formation temperature model and pressure coefficients, generating a formation pore pressure model using the mud-weight pressure model, and adjusting the oilfield operation based on the formation pore pressure model.

摘要： A technique includes identifying a fracture polygon intersecting a voxel of a three-dimensional grid of voxels representing a region of interest of a hydrocarbon-bearing reservoir based on data indicative of a discrete fracture network. The technique includes partitioning the polygon with a regular mesh of points and determining a number of the mesh points inside the voxel and inside the polygon. The technique includes estimating an area of the fracture inside the voxel based at least in part on the determined number of mesh points inside the voxel and inside the polygon. The technique includes determining at least one property of a portion of the hydrocarbon-bearing reservoir, which coincides with the voxel based at least in part on the estimated area of the fracture.

摘要： A logging tool capable of making different types of measurements is provided, and a plurality of measurements on a formation are obtained. Certain mineral properties of the formation are assumed and a mixed properties theorem for the formation is invoked. Upper and lower velocity limits for sonic waves traveling through the formation are determined using the above information. Biot's constant is also computed using the above information. LWD data on the formation is obtained and an effective stress is determined. A total stress is determined and, from that and the other information, a pore pressure is determined.
