Unconventional Optimization


From seismic and geomechanics data to recovery optimization

Natural fractures and stress orientation can impact the flow and the variability of the pressure field around hydraulically fractured wells.  We developed a workflow build permeability models for flow simulation constrained by 3D seismic, geologic data and concepts, geomechanics observations, and dynamic data.

Fracture information from seismic

Use 3D poststack seismic attributes to generate volumes of natural fracture orientations and intensity calibrated with independent fracture data. Click here for more details.

Hydraulic fracture configuration

Using concepts developed from applications specialized in hydraulic fracture modeling (like ResFrac® or Gohfer®), generate  elliptically shaped hydraulic fractures that capture those variations either for a few stages or the whole well. 

Permeability models

Identify reactivated natural fractures, estimate permeability enhancements, and upscale continuous fracture model to effective permeability models, perm anisotropy, sigma, and other inputs to flow simulation. Rank scenarios for different hydraulic fracture configurations. 

3D stress models

Use stress measurements or existing volumes that consider 3D variability in pore pressure, Shmin, or rock types to generate 3D grids of geomechanical parameters or proxies. 

Natural fracture reactivation

For given seismic derived natural fractures orientations, 3D stress field, hydraulic fractures geometry, and fluid pressures, analyze the likelihood of reactivation of natural fractures using Mohr-Coulomb faulting theory.  No DFN required.

Dual media flow simulation

Perform fast flow modeling to estimate initial production, stimulated reservoir volume (SRV), and expected recovery for different scenarios.
