Session I - Geomechanical Characterization Techniques

Chairs: Faustino Monroy Santiago, Pemex and Joaquín Mendiola Sánchez, Instituto Mexicano del Petroleo

Geomechanical models, such as the distribution of stresses, mechanical properties and pore pressure—calibrated with cores, logs and field data, are fundamental for the oil field characterization, and the development and exploitation of reservoirs. In this session, geomechanical characterization methods and procedures using experimental and field techniques are presented, together with the integration with petrophysical, flow and electrical properties. All these are necessary to address drilling, completion and reservoir challenges in oil and gas reservoirs.

Session II - Seismic and 3D Modelling Geomechanics

Chairs: Gerardo Ronquillo Jarillo,  Instituto Mexicano del Petroleo and Luís Carrillo Galicia, Pemex

Predominantly operators use GeoMechanics for well planning or when they have experienced drilling problems but usually do not include it at the exploration stage. Basically three components can make a great difference for an exploration drilling success: a good operational planning, knowledge of the geological environment, and a good quality of 3D seismic data for reveling the variations and distribution of the porepressure, elastic and rock mechanics parameters. From Seismic acquisition, with a geomechanics proposal the seismic velocities can have the resolution improved for a better 3D Pore Pressure Prediction. A geomechanics integration workflow based at the 3D seismic velocity cube will be presented showing some workflow and historical cases.

Session III - Well Drilling: Planning and Optimization I

Chairs: Víctor Vallejo Arrieta,  Pemex and Daniel García Gavito, Pemex

A constant challenge in the oil industry is improving drilling performance and optimizing project economics reducing non-productive time (NPT) and applying industry best practices. The industry realized that geomechanics analysis and pore pressure prediction for well planning and for field development well planning can avoid serious well drilling problems. Pre-drill geomechanics studies and pore pressure prediction work can significantly reduce the risks and potentially reduce the costs for drilling exploration wells. This section will show how a pre-drill geomechanics study can impact the well design and drilling performance. The geomechanics workflow is part of the multidisciplinary methodology and can be applied from pre-drill phase to real time execution phase.

Session V - Reservoir Geomechanics 

Chair:Ernesto Ladrón de Guevara Torres, Pemex, and Victor Salazar, Computer Modelling Group

Reservoir engineering (and simulation) must consider the geomechanical behavior of porous media to take into account very important recovery processes such as thermal recovery in oil sands, compaction drive in soft and unconsolidated reservoirs, subsidence, stress sensitivity in fractured, microfractured and vuggy media, coal seam stimulation, etc. This session will give an overview of the geomechanical aspects of naturally fractured reservoirs and sandstone reservoirs, describing some recent advances in coupled reservoir and geomechanical modeling, and will present several case studies of field applications on subsidence and cap-rock integrity.

Geomechanics is a critical component in the process to develop optimized stimulations in complicated, naturally fractured unconventional plays, which are often developed with multi-stage hydraulic fracturing techniques in long horizontal wells. This session will focus on the geomechanics elements central to multi-stage horizontal wellbore stimulation design, and the optimization and modeling of hydraulic fracturing in the presence of weak planes and natural fractures through modeling.

Session VIII - Well Completion

Chairs: Germán Gómez Serna, Americo Fernandez, Baker Hughes

The designing of a completion system has a significant impact on the well life and its expected production. Well related issues like depletion and sand production are not usually optimized in the initial plan.  Hence, severe loss in productivity associated to reactivation of faults (shearing and collapsing casing and liners) can occur or dramatic loss of permeability due to localized reservoir compaction. These are issues that can be assessed and remediated with geomechanics modelling. Furthermore, in naturally fractured reservoirs, a geomechanical model can be used to determine how the stimulation plan will affect the near-wellbore zone. In unconventional reservoirs, the geomechanical model is used to improve the efficiency (number of fractures to be stimulated) and the estimate of volume of the stimulated zone.
