GEOMECHANICS INTEGRATION FOR DRILLING OPTIMIZATION


Implementation of an integral solution to support the exploration and production processes. 1D and 3D Geomechanics modeling, structural restoration and well stability analysis. 3D Geomechanics of the reservoir (pore pressure cube, 3D mud weight cube, fault predictions and fracture instability). Geomechanics of drilling (1D Mechanical Modeling of the Earth, prediction of well stability for well design, real-time Geomechanics, cavity analysis, prediction of surface hazards). Prediction of sanding production potential, hydraulic fracturing design. Includes analysis in different geological contexts on land, offshore, ultra-deep waters, salt and different reservoirs (conventional, bituminous shale oil, bituminous / compact gas sands, fractured carbonates). Deepwater channels and lobes. Geomechanics studies included into their drilling program, have been incorporated to mitigate drilling risk and optimize well design. Core test, breakouts and induced fractures from images logs, leak off test and drilling events are some of the different information used to calibrate the Geomechanics studies The building of the mechanical earth model is done following Schlumberger and PEMEX methodology which consist of following steps:

  • Data audit of the geological, petrophysical, seismic and drilling.
  • Structural modeling (cross correlation G&G with drilling  Info).
  • Mechanical stratigraph.
  • Pore Pressure.
  • Elastic properties and Rock Strength.
  • Horizontal stress direction.
  • Minimum horizontal stress magnitude.
  • Maximum horizontal stress magnitude.
  • Failure mechanism analysis and operational windows .
