VAS detected ideal pay zones in the STACK play and reduced costs
An operator in Oklahoma wanted to boost return-on-investment (ROI) in the Anadarko Basin’s STACK play. They needed to quickly identify the highest-potential hydrocarbon production zones and avoid conventional logging the 1- to 2-mile-long laterals to reduce operational costs and risks.
The Volatiles Analysis Service (VAS) reservoir characterization from Baker Hughes, a GE company (BHGE), was proposed for formation evaluation. An initial mile-long lateral was planned, to be followed up by analyzing 25 more laterals and additional pilot vertical wells.
VAS provides a cost-effective, non-invasive formation evaluation log generated from drill cuttings or core plugs. The fast, high-quality log identifies pay intervals and characterizes hydrocarbon zones with no additional rig time. It helps improve well evaluation by
- Identifying recoverable oil and gas in laterals that would otherwise be completed blind, or without evaluation
- Estimating levels of compartmentalization
- Quantifying rock mechanical strength to optimize stage placement and fracture intensity of laterals
- Pinpointing filling reservoir migration conduits (faults) and organic acids
