ABSTRACT

 

PetrelTM is an integrated workflow software that allows exploration and production companies to think critically and creatively about their reservoir models and lets geoscientists and engineers work together seamlessly.  In Schlumberger, PetrelTM is an essential tool used for integrated field studies.  It has strong 3D visualization capabilities to display detailed static reservoir properties resulting from a study.  Schlumberger Consulting Services designed a High Efficiency (HE) workflow inside PetrelTM to automatically update the static model after the input data have been changed.  A one week job can be finished in one day by using the HE workflow.  Furthermore, the HE workflow can be used to create a number of realizations of the model with different settings, and to automatically perform repetitive mapping tasks. 

 

Recently, Schlumberger Consulting Services used PetrelTM and HE workflow to perform an integrated reservoir study on an older Cotton Valley field of East Texas.  The study resulted in the identification of potential horizontal well locations in the Cotton Valley sands.  Some reservoir intervals within the Cotton Valley section can be prolific gas producers.  Several horizontal tests have encountered gas reservoirs which have exceeded clients’ expectations.  The static geological model was built by utilizing PetrelTM which significantly improved the methodology used to optimize remaining gas potential where sufficient pressure exists.

 

In this case, the use of Schlumberger’s HE workflow updating capability saved time while maintaining quality as no static geological model updates were done by hand.  Errors due to tedium were non-existent.  Time saved was spent on maximizing drilling opportunities in the project area.  This allowed well locations within these leases to be selected with confidence.
