Rethinking DSTs: Optimize Production Forecasting and Reeal Acreage Opportunities from Historical Data

For geologists and engineers, accurate reservoir characterization is often the difference between economic success and failure. One of the main tools to reduce reservoir uncertainty is drill stem tests (DSTs) which provide key information about formation pressure and fluid characteristics of the reservoir.
