Geomechanics

Full range of services for 1D-3D/4D geomechanical modeling for solving any complexity problems in all hydrocarbon field life cycles: 
  • Wellbore stability calculations taking into account the reservoir architecture and features of the overlying layer, well trajectory and design optimization.
  • ERD wells planning, the risks map and drilling road map development
  • Optimal downhole pressures estimation to prevent sand production
  • Selection of the most favorable perforation and stimulation intervals, analysis of stress barriers and rock mechanical properties to optimize hydraulic fracturing
  • Analysis of the wells columns and cement integrity and stability over the field development
  • Assessment of the impact of rock stress strain state changes, reservoir filtration properties, faults and cracks reactivation during field development on the hydrocarbon production efficiency.


Our service help you to achieve

Increasing well
life by preventing sand production
Improved field
production forecasting
by assessing changes in reservoir porosity and permeability when the pore pressure change
 
 


Drilling optimization: 

  • Well trajectory and construction optimization (casing shoes landing depths selection). 
  • Pore pressure estimation and abnormal high pressure zones forecast. 
  • Post-drilling and pre-drilling stability analysis of reference and planned wells, respectively, safe drilling window calculations, optimal drilling mud weight selection. 
  • Real-time drilling support and updating geomechanical calculations (24/7). 

Completion optimization: 

  • Allowable pressure depression assessment at the bottom of the well to minimize the risk of sand production during hydrocarbon production. 
  • Hydraulic fracturing designs optimization by building reliable geomechanical models that include elastic rock properties, the array stress state, as well as stress barriers to manage the risks of fracturing in aquifers or gas reservoirs. 
  • Casing integrity and cementing quality assessment. 

Field management: 

  • Surface deformation calculation in time under the influence of changes in pore pressure in the reservoir due to the hydrocarbons production or cyclical gas injection and production in underground storage. 
  • Cap rocks integrity ensuring, assessing the risk of man-made earthquakes, faults and cracks reactivation. 
  • Faults/cracks reactivation assessment with changes in reservoir pressure during production and injection of fluids. Faults and cracks behavior of when oil production conditions changes. 
  • Drilling waste disposal into the reservoir - optimal disposal intervals selection, selection of sludge pumping parameters selection.
