Sand Management

Improve sand management to optimize recovery

A critical element in sand management is the prediction of sand failure. Our better finite-element modeling is based on methodology developed by Statoil. We offer superior sand-production predictions to select smart perforation intervals, determine the best perforation strategy, improve production by determining maximum sand-free drawdown, and optimize completion and well intervention planning.

Enhance sand predictions with advanced material modeling

Our experts use elasto-plastic material models calibrated against laboratory tests for use in the sand modeling finite-element simulations. The simulations use a fully coupled stress/strain pore-pressure diffusion approach. We have an extensive library of analogous material models when lab tests are unavailable.

Manage sand-free drawdown, depletion

The tendency for wells to produce sand changes continually as stresses vary. Each sand-production study predicts the maximum drawdown for arbitrarily oriented wells by using finite-element models for different completion types. This is crucial for better well-completion decisions and optimized production.

Our experts also can calculate finite-element models for various stages of depletion, predicting the maximum sand-free depletion and improving the life of your reservoir.

Optimize perforations                        

We combine flexible-geometry, finite-element models with in-situ rock strength to yield selective perforation zones that avoid weak reservoir intervals and permit higher drawdowns. These models also can consider different phasing, shot density, and various geometries to optimize the full perforation strategy.
