A mechanical earth model is the geomechanical equivalent of a reservoir model: a depth-indexed description of stresses, pressures and rock properties, calibrated against observations. Built properly it answers questions across disciplines, from the safe mud weight window for the next well to whether a reservoir will produce sand at a given drawdown.

Depletion changes everything it touches. As pore pressure falls, the horizontal stresses fall with it, which reduces the fracture gradient and narrows the drilling window in mature fields, and it increases the effective stress on the rock, which can cause compaction, casing deformation and sand production. Wells drilled into depleted zones are a distinct engineering problem, not a repeat of the original wells.

The value comes from using one model for several purposes. The same stress and property description that defines the safe mud weight window also predicts sand onset, informs perforating and completion choices, feeds hydraulic fracture design and supports fault reactivation assessment for injection. Building it once and maintaining it is more efficient and more consistent than answering each question separately.

By the end of this training, participants will be able to:

• Define the content and purpose of a mechanical earth model.
• Specify the data required for geomechanical characterisation.
• Determine stress magnitudes and orientations and calibrate them.
• Derive rock mechanical properties from logs and calibrate to core.
• Apply geomechanics to wellbore stability and trajectory design.
• Predict sand production and apply it to completion selection.
• Assess depletion effects on stress, fracture gradient and casing loads.
• Evaluate fault reactivation and seal integrity risk.
• Apply geomechanics to casing and completion design.
• Manage model uncertainty and update models across the field life cycle.

The course is instructor-led. Participants build a mechanical earth model from log, core and test data for a real field, calibrate it against drilling experience and apply it to stability, sand prediction and depletion questions. Cases cover fields where geomechanics changed well design and fields where ignoring it caused failures. Participants are encouraged to bring their own data for discussion.

Organisations sending participants to this training will:

• Build one geomechanical model that serves drilling, completion and production.
• Reduce instability, sand production and casing deformation problems.
• Design wells for depleted and stress-altered reservoirs.
• Assess fault reactivation and injection risk.
• Improve consistency of geomechanical input across disciplines.

Participants will:

• Understand geomechanics and its application across well design.
• Be able to build and calibrate a mechanical earth model.
• Be able to predict stability and sand production.
• Understand depletion effects on well design.
• Be able to apply geomechanics to casing and completion decisions.

• Drilling and well engineers
• Geomechanics specialists
• Completion engineers
• Reservoir engineers in mature and compacting fields
• Petrophysicists
• Field development and technical authority staff

Upon successful completion of this training course, delegates will be awarded an official Certificate of Completion issued by the Petroleum Engineers Association (PEA), an ISO 9001:2015 certified training organization. The certificate carries 10 Credits and formally records the total learning hours completed.

Each certificate is signed by the Course Facilitator and the CEO of the Petroleum Engineers Association, and serves as verifiable proof of professional training that delegates can present to employers and professional bodies worldwide.
