Stimulation Job simulator

SMAPE uses one of the most advanced stimulation software systems currently available on the market for acidising design and reservoir simulation.

  • Design, Simulation and Analysis of matrix acidising treatments
  • Can be used for both carbonate and sandstone formation types

In carbonates, the purpose of acidising is to dissolve the rock matrix, forming new channels (wormholes) that bypass the damaged areas and lead to the wellbore. In sandstone formations, acidising focuses more on the dissolving of particles that clog existing pore channels rather than creating new ones.

The results can be displayed in real-time while the model is running, giving the ability to produce reports and plots during the job execution. Another important feature is the ability to monitor the evolving skin factor during job execution with transient pressure analysis theory. This specialised plot depicts the changes in skin factor as pumping proceeds, graphically showing the predicted clean-up.

The software has the possibility to use different models wellbore hydraulics, complicated geochemical reactions and heat transfer between the wellbore, reservoir and fluids. It can be used to simulate multi-layered reservoirs in deviated or horizontal wells. The software give the possibility to integrate the SMAPE DatAcq & RT Monitoring System to collect treatment data in real-time for job analysis.

The modes of operation are:

  • Acidising Design
  • Acidising Analysis
  • Reservoir Simulation

Acidising Design mode produces treatment designs to mitigate any combination of these four damage types:

  • Emulsions and Wettability change
  • Asphaltene and Paraffin deposition
  • Perforation and Gravel pack damage
  • Deep Wellbore Damage

Acidising Analysis mode is used before, during and after the job when the treatment schedule is known. It allows the user to refine the treatment prior to pumping, monitors progress during the job and history matches observed well response after pumping. StimPT contains reports, plots and investigative tools for matrix acid operations. Acidising Analysis Mode is intended for detailed pre-treatment design and also for real-data analysis and history matching. The real-data analysis may be either in real-time, or post-job with previously acquired treatment data.

Reservoir Simulation mode can be used to predict or match the production behavior of stimulated or un-stimulated wells. The unique features and powerful capabilities allow quick design, analysis and optimisation of the acid stimulation job. The Smape software package allows modifications to be made during job execution and assists in performing a complete post-job analysis. This results in lower treatment costs, increased production, and improved economics for customer.
