I 'm about to start a new project which will last 6 months , the topic will be : hydrocarbons recovery optimization , using geomechanical reservoir parameters changes ?
I would like to ask you if you know any oil and gas society who would work on such a topic ?? thank you
Manage geomechanical changes
Production and injection affects the levels of subsurface stress during the life of an oil or gas field and can cause severe field development and production challenges, such as compaction and subsidence, changes in reservoir permeability, water breakthrough, fault reactivation and breaches in caprock integrity. In the reservoir and the overburden, these geomechanical changes, combined with complex geology, can affect completion stability and cause casing collapse and sanding across the field. Time-lapse, or 4D geomechanical simulation is critical to understanding and predicting how reservoir properties will change throughout the life of the field.
Predict and calibrate
Schlumberger provides accurate predictions of reservoir behavior using the ECLIPSE, and Petrel software technologies. Predictions integrate data from a variety of sources—including 3D surface seismic, well logging, core data, and well test data, and can be calibrated with monitoring data such as 4D seismic, microseismic, repeat well logging, subsidence measurements, and wellbore stability events. A reservoir wide pore pressure distribution can be derived using velocity information from 3D seismic data and be calibrated with downhole pressure measurements (Modular Dynamics Tester).
Please, visit the Schlumberger Reservoir Geomechanical teams.
The Lawrence Berkeley Nat. Lab., papers at International Journal of Rock Mechanics and Mining Sciences, for example.
So, it is a worldwide and useful techniques that a lot of E&P co. and, so, societies, applying everyday Boussaid.

Please clarify the question. In raw form , as porosity and rock compresibility (the change of porosity triggered by change of effective stress) is a geomech property, I would classify "recovery methods using changes in mech properties" in 1. conventional depletion (change of porosity without substantial permeability change), 2. unconventional depletion (change of porosity with substantial permeability change, including Cold Heavy Oil Production with Sand, dilation occuring during SAGD, chalk, etc.) and 3. all methods related to fracking (the trendy engineered tight gas or oil fracking or the more conventional thermal fracking in injection wells, fracking associated with acidizing, etc). When you think along those lines all companies in the Oil & Gas industry tackle 1. Most tackle 3 these days fairly extensively. Looking into 2 is done in all majors and many others companies.
I would suggest you clarify your question.
There are a number of Universities and companies that work on this topic one way or another. But following Pierre Bergey's line of thinking I would suggest that you investigate depletion as a recovery mechanism. By that I mean that in mechanical terms depletion is the trigger of major changes in reservoir flow properties (i.e. poro-perm) and therefore, selective depletion (depletion in some areas of the reservoir more than others) might be a research line that might want to consider in order to meet the objective as you defined (Hydrocarbons recovery optimisation). I hope it helps.
Pierre Bergey thank you so much for you response sir , actually I would like to work on the recovery optimization of the unconventional depletion (not only permeability and porosity that I will work on but also other geomechanical settings such as the poroelasticity and also the stress changes in situ ) .
I would be gratefull for you could help me to get an internsphip
