Oil & Gas

Production of Oil and Gas shifts from easily accessible reservoirs to those which are located at greater depths, or in formations with complex geological history. These come with larger risks and hazards.

Geo-mechanical analysis of Oil & Gas reservoirs or wellbores is one of the specialties of DIANA as its extensive library of material models, element types and analysis functions are well suited for this purpose. These include:

  • non-linear material models for fracturing
  • shear-failure
  • creep and crushing of rock and frictional fault modelling
  • automatic meshing procedures for 3D formations starting from geological model data 
  • distributed pressure fields and material properties
  • anisotropic material models for up-scaling
  • automatic and user defined solutions procedures for nonlinear problems
  • thermal and flow-stress effects
  • efficient direct and iterative parallel-processing solvers 
  • powerful visualisation of models and results

DIANA will help to quantify rock-compaction, stress changes, fault slipping in reservoirs and overburden and surface subsidence as result of and related to production of oil and/or gas. DIANA can also be used on wellbore scale to quantify rock failure, casing deformations and cementing integrity during well completion, or operational conditions such as pressure or temperature shocks or fault sliding.

Furthermore, the program is structured such that all several different analyses can be performed in one analysis command sequence. 

In addition to the oil & gas specific technical data and specifications below, see also the general technical information.  Our range of brochures are also available for download.  Or, if you have a specific question about DIANA that you would like to ask, please use the webform.
