What we do
General Information
Pre-drill geomechanical model is the first move to effective well designing and drilling in complicated geological environments or complex wells geometries.
Service
Predrill Model 1D
Geomechanical problems in challenging areas are estimated to be the cause of 45% of drilling- related NPT’s. Our 1D Geomechanical model is the first step to successfully planning your operation by detecting instabilities and reducing mechanical risks. Our geomechanics models and workflow allow us to identify and manage high-risk topics such as:
High pressure zones
Mechanical / Chemichal instabilities
Natural fractured areas
Intervals with plane of weakness
Weaker rock zones
Borehole cleaning problems due to instability
The 1D geomechanics study includes the review of offset wells information to calibrate in an effective manner the geomechanical model. Futures of this models are:
Essential screening for well design and drilling engineering
Safer mud-weight window planning. Including the predrill pore pressure prediction
Multidisciplinary expertise for model calibration and complete risk detection
Service
Risk Analysis Map (RouteMAP)
Once the risks and possible causes have been identified, the integrated risk map for the well to be drilled is defined. This is based on a matrix that allows evaluating the probability and consequence of the defined risks together with the mitigations and residual hazards
Service
Real Time Geomechanics
Our pool of geomechanics and drilling performance experts will analyse all available information from sensors, logs and drilling operations in real time to identify potential instability problems, possible causes, and effectively communicate next hour's forecast to your drilling team to execute contingency plans and avoid potential hazards during drilling operations. The parameters we track and consider inside our real-time model include:
Real-time while drilling logs such as GR, resistivity, density and sonic logs
ECDs, ESDs, well cleaning
Tracking of torque and drag models
Results from LOT, ELOT, and CIT tests
Fluids properties for chemical instability analysis
Analysis of morphologies and cavings rate trends
Monitoring of well stability parameters and pore pressure evaluation in real time
Generation of early warnings and lessons learned
Service
Postdrill Model
Once the risks and possible causes have been identified, the integrated risk map for the well to be drilled is defined. This is based on a matrix that allows evaluating the probability and consequence of the defined risks together with the mitigations and residual hazards.
