Abstract
Methods and apparatus that use microseismic event data, stress data, seismic data, and rock properties to predict the hydrocarbon production success of a well location are disclosed. An example method generates a hydrocarbon production function based on information associated with at least a first well location, obtains information associated with a second well location, and calculates the hydrocarbon production function using the information associated with the second well location to predict the hydrocarbon production of the second well location.
Claims12
A method of estimating a fracture volume, comprising:
- obtaining a set of microseismic data associated with a fracture;
- generating a voxelized space based on the set of microseismic data;
- selecting pairs of points from the set of microseismic data that fall within at least one of a spatial or a temporal threshold;
- identifying voxels from the voxelized space, wherein the identified voxels correspond to the pairs of points and points linearly dependent on vectors connecting the pairs of points, by:
- infilling the identified voxels in the voxelized space by performing a linear interpolation using segments from the vectors connecting the pair of points;
- and
- estimating the fracture volume based on the identified voxels.
A system for estimating a fracture volume, comprising:
- a processor and a memory coupled to the processor, wherein the processor is programmed to:
- obtain a set of microseismic data associated with a fracture;
- generate a voxelized space based on the set of microseismic data;
- select pairs of points from the set of microseismic data that fall within at least one of a spatial or a temporal threshold;
- identify voxels from the voxelized space, wherein the identified voxels correspond to the pairs of points and points linearly dependent on vectors connecting the pairs of points, by:
- infilling the identified voxels in the voxelized space by performing a linear interpolation using segments from the vectors connecting the pair of points;
- and
- estimate the fracture volume based on the identified voxels.
A machine readable medium having instructions stored thereon that, when executed, cause a machine to:
- obtain a set of microseismic data associated with a fracture;
- generate a voxelized space based on the set of microseismic data;
- select pairs of points from the set of microseismic data that fall within at least one of a spatial or a temporal threshold;
- identify voxels from the voxelized space, wherein the identified voxels correspond to the pairs of points and points linearly dependent on vectors connecting the pairs of points, by:
- infilling the identified voxels in the voxelized space by performing a linear interpolation using segments from the vectors connecting the pair of points;
- and
- estimate the fracture volume based on the identified voxels.
