Professional Experience

Aspen Brook Logging Inc. 12/2000-Present
C.A. Bohling,
P.O. Box 17928,
Golden, CO 80402

Senior Geologist and Log Analyst. Provided geologic wellsite consulting services primarily for Encana Oil & Gas Inc. on the Jonah Field, Wy. with occasional small projects in the Wind River and Williston Basins through Aspen Brook Logging. (At present all of my consulting is through Aspen Brook Logging Inc. with Apex Exploration only generating and drilling its own prospects in the Texas- Oklahoma Panhandles.) At present consulting for RPM Geologic, Denver, Co.

Apex Exploration Inc. 4/85-Present
President and Chief Operating Officer. Through my company Apex, I provide consulting services to the oil and gas industry in qualitative and quantitative well log analysis for exploration, formation evaluation, completion design, and reserve calculations, subsurface mapping, geologic wellsite supervision including sample and gas logging, DSTs and coring, prospect generation, land and 3rd party prospect evaluation, and the interpretation of depositional environments and Sequence Stratigraphy through extensive study of subsurface data (cores, thin sections, dipmeters and Formation Micro-imaging tools, recent and old well logs, seismic and drilling samples). Apex also generates and drills (doing everything from prospect to pipeline) its own oil and gas prospects in the Texas and Oklahoma Panhandles and S.E. Colorado.

Some longer term projects:

2000-2012 Well site Geologic consulting for Encana Oil and Gas Inc. (USA), Denver, Co. in the Jonah Gas Field, Wyoming. Responsible for logging drill cuttings, make sample and gas logs for 8 drilling wells which I monitored simultaneously and remotely to evaluate probable reservoir productivity and pick a final TD for the well based on my findings. This resulted in Encana, over the years, from TD’ing in the Yellow Point to drilling all of the Wardell and then the entire Mesa Verde, as sample and gas shows showed these older formations would be productive and economical as well. Maintenance and repair of all equipment for accurate collection of data was an additional responsibility.

1998-2000 Geologic consulting for Goodson & Assoc., Lakewood, CO
On site drilling, ASTM Engineering Soil Descriptions and installation of monitoring wells for various State and Federal Environmental and DOT projects (T-Rex project to widen I25 and put in light rail). This work required me to be recognized as a Professional Geologist by the State of Colorado.

1996-1997 Consulting for Thrace Basin Natural Gas, Hayrabolu, Turkey
Bought/refurbished and moved a rig from Farmington, NM to Turkey. Geologic and log analysis consulting, completion design and treatment, well testing, along with buying all types of oil field equipment and completion chemicals and designing the septic tank and leach field for waste disposal at the permanent field camp in Turkey.

1995-1996 Consulting for StrataSearch Corp., Golden, CO
Run Time Domain Electromagnetic Surveys in Oklahoma, Kansas, Colorado, New Mexico, Wyoming and North Dakota. Field operations which included layout and surveying of transmitter and receiver stations along with maintenance of all equipment along with occasional fabrication of some interfacing parts.

August/ September 1986, Lectured and Consulted in the Peoples Republic Of China
Invited to lecture at the Daquing Petroleum Institute on the use and application of dipmeter logs in exploration and developmental drilling. In addition to the videotaped lectures I also provided consulting services on a number of log analysis projects for the Daquing Field.

Apex has provided consulting services to Encana Oil & Gas, Champlin Petroleum (UPRC), Avalon Energy, New London Oil, Caribou Energy, Beverly Exploration, Perry Exploration, Tunoil, Yellowstone Resources, Berry Energy, Murfin Drilling, Petrogulf Corp., Pantano Energy, Jayare Exploration, W.C. Payne Inc., Lario Oil & Gas Inc., Delta Petroleum, Marathon, Thrace Basin Natural Gas Inc., StrataSearch Corp., Goodson & Assoc., and the Peoples Republic of China.

Apex has completed drilling (farmout) agreements with Amoco Production Company, Phillips Petroleum Co., Exxon Corp., City Services- Oxy, BST Inc., Kaiser Francis, Questa, Ampet Inc., Jayare Exploration and Champlin (UPRC) Petroleum and drilled its own prospects on open acreage.

Since late 2000 Apex no longer does consulting but only generates and drills its own prospects in the Texas- Oklahoma Panhandles and Eastern Colorado.

Phillips Petroleum Company 5/80-4/85
Frank Phillips Bldg.,
Bartlesville, Ok. 74004

Supervisor: Wallace W. Souder
From 5/80- 12/80 employed as log analyst in the Formation Evaluation Unit of the Exploration Projects Section of Phillips Petroleum in Bartlesville, Oklahoma. Responsibilities:
1. Log analysis for enhanced recovery of the North Burbank oil field, N.E. Oklahoma
2. Log analysis for exploration holes Cesar Basin, N.E. Colombia
3. Application of log analysis techniques to bore gravity data (Permian Basin) and geothermal exploration and production (Imperial Valley, Ca.)
4. Generation and testing of interactive log analysis programs for hand held calculators (HP-41 C) to be used by personal for “quick look” log interpretation in the field.
5. Represented Phillips Petroleum Company on Winnifred Lake Tar Sands Project ( Alberta, Canada) in meetings with Amoco, Alberta Energy, and Petro-Canada. The purpose of these meetings was to determine, using log and extensive core data, the proper log analysis techniques to evaluate tar sand reserves and the economic feasibility of the project based on recoverable reserves of these tar sands.

Phillips Petroleum Company
Denver, Co.

Supervisor: Ronald Zdyb, Patrick Donham, Jerry Kreitner
From 1/81-4/85 employed as exploration geologist Mid-continent, Panhandle Region of Texas and Oklahoma in the Denver office.
Responsibilities:
1. Generation of oil and gas prospects in the Texas-Oklahoma Panhandles (Hugoton Deep Project).
2. Integration of geological and geophysical data for the application of seismic Stratigraphy to the search for Morrow sandstones.
3. Log analysis on all wells in the Mid-continent Region.
4. Determine if casing should be run and the intervals to be perforated and tested on holes drilled.
5. Geologic well site supervision, including sample and show analysis, open hole testing (DST’S) and quality control on logging runs.

During this time I was responsible for generating and getting drilled 32 exploration prospects of which 13 were successfully completed (40%) (see Appendix 1).

In May 1983, I received an Incentive Bonus Award from Phillips Petroleum in appreciation of my exploration success on the Hugoton Deep Project. This award was presented by Colin Wilkinson, Western Division Exploration Manager for Phillips.

Shortly after working for Philips Petroleum, in 1985, the Phillips Denver Office of Engineering calculated the annual average rate of return (AARR) on the wells I had drilled in the Texas- Oklahoma Panhandles (Hugoton Deep Project). This return was found to be 185% with an NTIR (Net Times Investment Return) of well over 25.

USGS, Branch of Oil and Gas Resources
DFC, Bldg. 25, M.S.939

Supervisor: Thomas Fouch, Ronald C. Johnson
Employed as a P.S.T., GS-7, Responsibilities included geologic mapping, measuring sections, drafting, well log correlation, construction of subsurface diagrams, qualitative and quantitative analysis of well logs, description of drilling samples, and collection of samples for thin sections, x-ray, and pollen analysis to determine reserves of gas in place. This work done on the Cretaceous and Tertiary rocks of the Piceance Creek Basin, N.W. Colorado as part of the Western Tight Gas Sands Project.

Employment prior to 12/77 was as an Electronics Technician repairing commercial two-way radio equipment and consumer electronics.
