Meet Our Team


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.

Mr. Cook is a Partner with Rose & Associates, LLP (R&A) and Manager of Lognormal Solutions, Inc. (LSi), the software company of Rose & Associates, LLP.
