The Geomechanics Symposium is an international academic event that has been held every two years since 2004, and becomes the opportunity to analyze the main challenges and current issues of geomechanics in the hydrocarbon industry. This particular version addresses geomechanics as part of a proactive design process that seeks to exploit the benefits and manage the negative impacts of extractive oil and gas operations.

General objective of the event

Promote a space for the dissemination of knowledge and discussion of topics related to geomechanics, in which academic specialists and representatives of the oil industry, national and foreign, interact, oriented to face the main challenges of geomechanics in the exploration and exploitation of oil fields. hydrocarbons.

Target audiences

Petroleum engineers, geological engineers, civil engineers, geologists, researchers, students of petroleum engineering, geological engineering, civil engineering and geology and professionals from all areas related to reservoir engineering who are developing topics related to reservoir geomechanics hydrocarbons.


  • Geomechanical aspects of mature fields.
  • Geomechanics of heavy oil reservoirs and thermal recovery.
  • Geomechanics of unconventional reservoirs.
  • Well stability and integrity.
  • Hydraulic fracture.
  • Sand production: prediction, quantification, management and modeling.
  • Seal coat integrity.
  • Geomechanical damage.
  • Yacimientos naturalmente fracturados.
  • Geomechanics related to fluid disposal activities in the subsoil: water, gas, CO2, among others.
  • Geomechanical management of reservoirs.
  • Geomechanical laboratory tests.
  • Emerging technologies applied to geomechanics.

Geomechanics of Unconventional Reservoirs
May 3 & 4, 2021

Geomechanics – in both completion and drilling operations – has become a critical technology in the development of Unconventional Reservoirs. This course presents the application of the basics of oil field geomechanics to unconventional developments; specifically, the role of stress, pore pressure, mechanical properties, and natural fractures on hydraulic fracturing operations. The first portion of the course will focus on the importance of oil field geomechanics, geomechanical modeling and workflows as a necessary part of reservoir characterization for Unconventionals. The second part of the course will focus on the geomechanics of hydraulic fracturing for Unconventionals with an emphasis on proper characterization, modeling, interpretation and field aspects (i.e., hydraulic fracturing in heterogeneous rock masses with the presence of discontinuities and weakness planes). At the end of the course, it is expected that attendees will be able to specify and QC a geomechanics evaluation program for Unconventionals, and understand the key geomechanical issues and inputs for hydraulic fracture optimization in Unconventionals. The course will be virtual, with simultaneous translation and with a duration of 14 hours.

The course approaches geomechanics from an engineering aspect of completion optimization in Unconventionals. The course is intended for geoscientists, reservoir, drilling, and completion engineers, and students with background in geomechanics who are engaged or are interested in the development of Unconventionals.
