Field Optimization Study for an International Tight Sand Reservoir

Subsurface Dynamics is an independent engineering and geoscience consulting firm with extensive experience in reservoir characterization, modeling and simulation.  We provide a full spectrum of engineering and geophysical services from data acquisition to final data integration and full field development programs.

"Subsurface Dynamics was tasked with developing a field development and optimization program including location of future development wells and selection of perforated intervals. This study included integration of all geophysical, geological and engineering data as well as economic analysis."

Project Summary

Subsurface Dynamics was tasked with developing a field development  and optimization program including location of future development wells and selection of perforated intervals.  This study included integration of all geophysical, geological and engineering data as well as economic analysis.

CLIENT: UNDISCLOSED

fORMATION: International tight sand reservoir with multiple producing intervals

Scope of Work

Using proprietary data from the Client , Subsurface Dynamics completed a petrophysical model, constructed a Geological static and history matched dynamic model.  The dynamic model was used to perform sophisticated full field  multi layer well placement optimization and create probabilistic forecasts.  Wellbore modelling was also completed to quantify the contribution of each producing zone. Completion optimization was performed to optimize the staging and tonnage for sand placement as well as well trajectories and optimum length of horizontal sections. 

Result

As a result of the full field development workflow, the following  enhancements were achieved:\

  • Location of missed pockets of recoverable resources were quantified

  •  Selection of infill locations to increase future field productivity by 40%

  • Improvement  in individual well productivity by 20% by improving completion design and maximizing zonal contributions.
