3D modeling

Ufa Scientific and Technical Center performs a range of services for creating and history-matching of static and dynamic reservoir models

 
 

STATIC RESERVOIR MODELS


Tasks
  • Oil and gas reserves calculations 
  • Planning drilling campaigns (well design and placement) 
  • Risk analysis and uncertainty quantification 
  • Creating framework for fluid flow simulations
Main workflow stages
  • Gathering, analysis and preparation of the required data, uploading
  • Structure modeling (reservoir framework)
  • Creating a grid (3D grid), averaging well data for the grid
    (assigning properties to grid cells)
  • Facies (lithology) modeling
  • Rock physics modeling
  • Hydrocarbon reserves calculations


DYNAMIC MODELING


Dynamic or fluid flow models are an integral part of field development project documentation which a license holder or operator company is required to submit to the designated approving authorities. These models are also used to monitor field depletion processes

Tasks
  • Plan production levels and optimize reservoir depletion rates
  • Detailed study of in-situ fluid flow dynamics
  • Study of well behavior and reservoir performance
  • Evaluation of field development investment risks
Main workflow stages
  • Gathering, analysis and input control of initial data
  • Selecting model types
  • Creating a reservoir model
  • History-matching including the results of completed geological and technical operations (workover, IOR/EOR, remedial cementing etc.)
  • Analysis of the current reservoir energy state for the modeled area based on current reservoir pressure maps created from the dynamic fluid flow model
  • Localization and feasibility studies for remaining recoverable reserves within the planned drilling location
  • Forecasting and analysis of results
Advantages
Reservoir simulations are a cost efficient tool for increasing the success rate of new wells including the following:
  • On-the-spot analysis of depletion state for the target reservoir
  • Identification of remaining reserves, by-passed oil and high-yield sweet spots not drained by nearby wells with the existing depletion pattern
  • Selection of best well placement strategy and optimum well trajectory based on historic production from offset wells and current areal and vertical sweep
  • Selection of best net pay intervals for completion
  • Forecasting well production
