Meet Our Team
Peter Carragher, Managing Partner at Rose & Associates, LLP, has been involved in oil and gas exploration since 1974 (after receiving his B.S. degree in Geology from King’s College London and joining Amoco). He has evaluated and drilled prospects in most of the world’s oil and gas provinces. Since 1990, he has been involved in developing and applying exploration risk assessment techniques and portfolio management processes.
From 1989 to 1994, Carragher served as Manager of Amoco’s Basin Analysis Group for Worldwide New Ventures and was then promoted to lead Amoco’s Prospect Quality Team from 1994 until 1997, an effort directly responsible for creating value for Amoco’s Worldwide Exploration effort. He then served for two years as Manager, Upstream Portfolio Analysis for Amoco immediately prior to the merger with BP. In 2003, BP named him as Head of Discipline for Worldwide Exploration, and later named him VP of Geoscience and Exploration, helping assess new resources and identifying new areas of exploration potential.
He has extensive experience in designing exploration strategy, process, and organization capability that has proven to lead to improved business performance. He also is a leader in helping companies liaise more effectively with seismic acquisition vendors at the portfolio level to best leverage a company’s exploration budget.
David M. Cook, Jr.
David M. Cook, Jr. (BS, Geophysics, Texas A&M University) is an explorationist who served in a variety of interpretation, supervisory, planning, and exploration consulting positions during a 22-year career with Mobil and ExxonMobil. In 1991, he performed Mobil Exploration’s first statistical audit of pre-/post-drill results recommending strategy improvements in process and risk assessment methodology. He assumed management of Mobil’s prospect inventory in 1992, formalized performance reviews, and captured technical “Lessons Learned” for all wildcats.
In 1994, Mr. Cook developed and implemented a globally standardized methodology for pre-drill reserves estimation based on lognormality and reality checking. He organized Mobil’s “Risk/Volumes Network” to ensure consistent reserves and chance of success estimation. During his last assignment, he advised Management on decision analysis techniques, consulted on exploration risk analysis and economics, and transformed Mobil’s prospect inventory into a knowledge management tool, facilitating integrated strategic planning and broader, accelerated global technical learning. He also assisted in development of Mobil’s play/concession portfolio modeling process, provided portfolio rankings based on multi-attribute utility theory, and consulted with Mobil’s worldwide teams on process implementation.
Since joining Rose & Associates, Mr. Cook has conducted resource / risk analysis training and consulted on application of risk processes to specific prospects and geologic plays to E&P clients around the world working in diverse petroleum systems such as Offshore Canada, Gulf of Mexico, Rocky Mountains, Central and South America, Cambodia and Mozambique. Additionally he has developed new courses and updated the firm’s training manuals and presentations.
Since 2004, Mr. Cook has managed R&A’s software subsidiary, Lognormal Solutions Inc., successfully re-developing existing software programs including the Prospect Risk Analysis Suite’s three tools – MMRA, Toolbox and Multi-Zone Master – plus the Portfolio Risk Analysis (PortfolioRA), Risk Essentials and Portfolio Essentials software. Two new software programs have been developed and delivered including the UnConventional Resource Analysis (UCRA) tool for improved probabilistic modeling of low permeability resource play volumes, production, capex/opex spending, cash flow and economic metrics along with the Risk Analysis Portfolio Tracker (RAPT) database, R&A’s performance tracking tool, to allow pre-drill & post-drill resource analysis comparison and provide lessons to facilitate subsequent improvement in resource and chance predictions.
