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
