Consultants and Contractors
Esther joined UEORS during the summer of 2018 to cover HR duties. She comes to us with more than 30 years of administrative experience at The University of Texas at Austin.
Chrissi Brown Moroney
Chrissi has three decades of experience in the petroleum industry. She has worked in Kazakhstan, England, Indonesia, Kuwait, China, Mexico, and onshore and offshore United States conducting reservoir simulation studies and acquisition evaluations for fields in Angola, Bahrain, Canada, Brazil, Brunei, Azerbaijan, and Qatar. In these studies, she has evaluated EOR and improved oil recovery (IOR) technologies such as surfactant flooding, hydrocarbon miscible floods, nitrogen injection, CO2 injection, high pressure sour gas injection, and horizontal well, big-bore, and multi-lateral well performance. Dr. Moroney is skilled at reserves determination, field development planning, and decision and risk analysis to develop robust project designs that achieve economic benchmarks while minimizing reservoir and economic risks.
