Abstract: Horizontal Wells in Rotliegendes Gas Fields - Evaluation and Optimization

SALTER, RICHARD P, MARCUS SARGINSON, D. BOARDMAN, A.A.P. TWEEDIE, and PATRICK CORBETT

A dataset comprising 22 horizontal wells in 14 fields from the Permian Rotliegendes Eolian Previous HitSandstoneNext Hit has been analyzed in detail. Integrated geoscience and engineering methods were applied for interpreting log and well test data, providing guidance on data collection, developing predictors for Previous HitpermeabilityNext Hit and well productivity, and optimizing well location and drilled length. The data analyzed is summarized in six poster panels concentrating on the following elements.

i) Previous HitPorosityNext Hit - Previous HitPermeabilityNext Hit Characteristics

While the study focused on a particular geological depositional setting there is much relevance to the evaluation of horizontal wells across a range of reservoir types.
