Career History

Sep 2015 – Current

Triangle Petroleum Consultants,

President/Owner

Key Studies and Services Offered

Performed both annual and semi-annual reserve and economic updates to various independent producers who had resources in various producing basins in the continental United States.

Performed a detailed waterflood investigation into the feasibility of secondary recovery operations in the Misener sand in several sections of Grant and Alfalfa counties, Oklahoma.

Performed a highly detailed study into the performance characteristics of 67 Woodford oil and gas wells in Canadian County, Oklahoma that predicted optimum maximum recovery density for wells producing in an over-pressured solution gas drive reservoir.

Routinely consulted with potential clients concerning investing in the upstream oil and gas industry.

Regularly made recommendations on pipe-setting in the Lansing/Kansas City limestone throughout central and northwestern Kansas and southwestern Nebraska based on detailed petrophysical evaluations as a service to non-operating clientele.

Taught the basics of petroleum reservoir engineering as it applies to non-engineers as a guest instructor at the University of Tulsa

Feb 2014 – Sep 2015

Senex Energy Limited – Australia

Chief Reservoir Engineer

Key Responsibilities

Lead a team of Reservoir Engineers, Petrophysicists and technicians in developing and exploiting both green and brown fields in the Cooper and Surat Basins in SA

Manage the reservoir team, incl. HR, training, performance reviews, recommendations for promotions

Communicate with engineering consultants in the quantification of the corporate reserves Assume direct responsibility for all areas of exploration and completions support, including perforation intervals and shot density, methods of artificial lift, future reserves determinations and economic outcomes.

Maintain responsibility for the Reservoir/Production team

Act as member of the Operations Leadership Team

Major Accomplishments

Monitored and had significant input into the creation and development of reservoir simulation models for several fields in the Cooper Basin. This resulted in the recognition of an additional 16.2 MMBO of 2P and 22.7 MMBO of 3P secondary reserves.

Delivered annual reserves update on-target and on-time which resulted in:

oincreasing 1P net reserves for a replacement ratio of 154%

oincreasing 2P net reserves for a replacement ratio of 327%

Mar 2013 - Feb 2014

Nadel and Gussman, LLC – USA

Reservoir Engineer

Key Responsibilities

Provided year-end reserve updates to senior management and the family for the purposes of capital Budgeting, cash distributions and taxation

Mentored geologists and engineers in the fundamentals of reservoir engineering, basic and advanced decline curve analysis and economic evaluation techniques

Undertook studies to create new exploitation opportunities (specifically targeting underdeveloped reservoirs and secondary reserves

Major Accomplishments

Provided revised petrophysical analysis of the Osage County Mississippian reservoir which involved re-evaluating the Mississippian C zone that is deposited directly above the Kinderhook interval. This resulted in providing a better understanding of future drilling targets in this elusive carbonate environment.

Evaluated waterflood candidates in both Coal and Payne Counties, Oklahoma that on a combined basis potentially have over one million barrels of secondary reserves. These are ongoing but very promising studies.

Dec 2011 – Dec 2012

Newfield Exploration – USA

Reservoir Engineer

Key Responsibilities

Provided quarterly and year-end reserve updates to senior management for the purposes of SEC filings

Provided reserve and capital input for the annual budgetary process

Updated the weekly budget forecast for the Coalgate District

Mentored interns and new hires in the fundamentals of reservoir engineering, basic and advanced decline curve analysis and economic evaluation techniques

Acted as key member of the Base Production Management in both the Arkoma and Elk City Districts

Major Accomplishments

Made a major study of the Arkoma Oil Window in 2N-9E for the purpose of understanding well density and spacing effects and the impact of fracture stimulation interference. Although this study found only minimal future development potential in that area, its findings were utilized in the planning of the development of the Anadarko Woodford (liquids-rich) shale play.

Provided engineering support to implement a program to identify wells that were tubing restricted with the result that 15 wells received an uplift of over 250 MCFGPD on average or more than 4 MMCFGPD in total.

Played a major role in the study of historical performance trends in the Arkoma Woodford Shale play that determined the nature of the hyperbolic decline exponent over time which again was used going forward in the Anadarko Woodford Shale play.

Conducted a study of the impact of cross-sectional drilling in the Arkoma Woodford Shale Play and the economics of the resultant super-extended laterals at various economic scenarios.

Mentored an intern during the summer of 2012 whose project was the optimum future development plan for existing HBP acreage in two townships in the Coalgate District

May 2004 – Sep 2011

Chesapeake Energy Corporation – USA

Senior Reservoir Engineer

Major Accomplishments

Performed all aspects of the reservoir work for the exploitation of a major waterflood project in Howard County, Texas that resulted in the addition of two million barrels of proven secondary reserves to the books of Chesapeake Energy Corporation.

Made a major regional study of the Haley area of Loving County, Texas that provided the impetus for Chesapeake to enter into the area and make it into a major deep gas play for the corporation.

Performed a reserve analysis of the Third Bone Spring oil play in the southern Delaware basin, which provided the impetus for Chesapeake to enter that play with the result of the booking of more than 700 BCFE of proven and probable reserves.
