Our services
Consulting services to create a Rock Mechanics’ Model –RMM- for an oil field combines the geomechanical conditions with the specific well trajectory, which produces a unique set of wellbore stability and/or pore pressure conditions for the well trajectory.
The analysis identifies those potential drilling hazards expected during the construction of a proposed well, allows the understanding of the likely wellbore behavior during well construction and can, therefore, be used to reduce uncertainty and risks.
The RMM specifically constructed for reservoir zone based on well logs and calibration data is the source to feed hydraulic fracturing simulators. The model allows a more accurate evaluation of fracture geometry and direction, the intervals to be fractured, the job schedule and the treatment requirements.
Geomechanics for Drilling
1D Rock Mechanics Model validated with G&G Model, crossing the boundaries between drilling, geology, geophysics, geomechanics, and mud engineering.
Wellbore Stability Model and Mud weight window definition, for a specific proposed well trajectory, using data from the RMM, referenced against MD and TVD.
RMM is constructed considering both drilling mechanics risk analysis, and the Wellbore Stability Events reported in adjacent/offset wells.
Nominal mud weight, ECD, and casing plan.
Hole cleaning risks based on wellbore inclination identifying the critical sections of the wellbore.
Drilling hazards identifying intervals of specific geomechanical problematic behaviours for the proposed trajectory.
Pre-spud meetings and workshops to share the wellbore stability findings with the operational team.
Geomechanics-related updates the elements of the RMM providing recommendations for new trajectories.
Technical support during planning and operations including geomechanical modeling of the proposed and final well trajectory and architecture.
