Reservoir Characterization Via High Quality miniDST
Speaker: Vinay Mishra
Abstract : Reservoir testing also referred to as Pressure transient analysis (PTA) is a critical requirement of reservoir evaluation for field economic decisions. A properly design testing provides deep characterization insights including reservoir properties such as permeability, skin factor, heterogeneity assessment etc. Decades ago conventional drill stem testing (DST) was the key tool to achieve the best results, but lately, wireline formation testing (WFT) tool acquired miniDST measurement has become a preferred choice due to cost, environmental and operational reasons. In the new era of formation evaluation, there is a tendency to acquire such reservoir dynamic data during the formation evaluation process instead of performing a conventional drill stem test. This presentation will discuss the compelling reasons for acquiring miniDST data by oil and gas operators especially in the offshore oilfields.
Reservoir dynamic tester tool mounted with oval shaped probe or straddle packers added with intelligent test design provides high quality transient data for reservoir characterization. High-rate pumps are included in the tool string which ensure that large pressure drawdown is created, thus enabling testing of a wide range of reservoirs with deeper radius of investigation. Latest technology in-situ fluid density and optical sensors allow advanced fluid characterization which is integrated with the miniDST results for comprehensive reservoir description.
Bio: Vinay K. Mishra, PE, is Senior Advisor reservoir
engineer with Halliburton, based in Houston Texas. He provides reservoir
engineering support primarily reservoir dynamic testing, downhole fluid
analysis, pressure transients and Micro-fracturing for Gulf of Mexico and US
onshore operations. He has over 20 years of experience, including his previous
experiences with ADNOC, Tachyus and Schlumberger in different roles of
petroleum engineering based in US, Canada, Libya, Egypt and India. He has co-authored
over 50 publications in international conferences including SPWLA and SPE.
Vinay has done B.S. in Petroleum Engineering from IIT-ISM, Dhanbad, India and
Masters in Petroleum Engineering from Texas A&M University College Station.
Vinay has been member of SPE and SPWLA and held committee member and session
chairs roles in several events. He is also registered with Texas Board of
Professional Engineers and Land Surveyors (TBPELS).
The SIG plans to host one meeting per year on
various topics pertaining to formation testing.

Some general SIG activities anticipated:
- SIG related meetings, workshops, short courses, and sessions at general/annual meetings
- Maintain contacts with other professional societies that are also concerned with formation testing
- Web-based information exchange, perhaps including posting of papers, experts list, question area
- Provide leadership for technical standardization activities or QA/QC related with pressure measurements or fluid sample acquisition
