Digital Workflow to Integrate Deep Transient Testing (DTT) and DST and Expedite Decision Making for Green Field Development

Résumé fourni par la source

Summary Developing a reservoir requires key data on reservoir quality, well productivity, and hydrocarbon volume. Traditionally, formation testers and Drill Stem Testing (DST) have been used, but both have limitations: formation testers have restricted pressure transient testing range, and DST involves flaring, which increases CO₂ emissions. In Southeast Asia, reservoirs are often laminated, thinly bedded, and compartmentalized, making DST of every zone costly and time-consuming. To address this, Deep Transient Testing (DTT) was introduced as a zero-flaring alternative that extends formation tester capabilities and reduces the need for DST, especially in laminated reservoirs. Numbers of DTT case studies from South-East Asia will be presented in this paper. With the total of 5 DTTs, a 71–99% reduction in CO2e (CO2 equivalent) quantities compared to DST. This paper will also discuss the integration of DTT and DST to help obtain layer information by using this digital workflow.
