This paper will discuss how accurate infill well development strategies for horizontal wells are efficiently developed using production and pressures from vertical discovery wells.

The work flow requires developing pattern* models for the vertical wells using best engineering assumptions for parameters, and then improving the reservoir description in the models using computer assisted history matching. The resulting rock properties are mapped between wells using a Kriging geostatistic algorithm. In the final step, different horizontal well locations and completion strategies are investigated to create an optimal well spacing and completion strategy. Close agreement between model production forecasts and recent horizontal well production and pressure records validates the accuracy of the approach.
