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 Sandstone has been analyzed in detail. Integrated geoscience and engineering methods were applied for interpreting log and Previous HitwellNext Hit test data, providing guidance on data collection, developing predictors for permeability and Previous HitwellNext Hit productivity, and optimizing Previous HitwellNext Hit location and drilled length. The data analyzed is summarized in six poster panels concentrating on the following elements.

i) Porosity - Permeability Characteristics
ii) Horizontal Previous HitWellNext Hit Porosity Logs
iii) Permeability Scale-Up for Eolian Dune Sequences -
Implications for Previous HitWellNext Hit Placement
iv) Geological Overview of Layered Rotliegendes Reservoirs
v) PI Prediction for Horizontal Wells in Rotliegendes
Reservoirs
vi) Rotliegendes Horizontal Previous HitWellNext Hit Production Log
Interpretation
vii) Horizontal Previous HitWellNext Hit Test Analysis

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 Previous HittypesTop.
