Firm History

Goolsby & Associates, LLC. was formed in 1998 to provide geological services to the petroleum, and extractive mineral industries. The "LLC." is based on a working knowledge and understanding of oil, gas, and mineral industry exploration and exploitation. In 2001, Goolsby & Associates, LLC. was changed to Goolsby, Finley & Associates, LLC.



Goolsby, Finley & Associates, LLC. has a combined experience of over 100 years in all phases of petroleum geology. This experience includes identification, generation and evaluation of prospects, and geological supervision of all phases of development and production. In addition, we have completed several economic analyses to evaluation both prospective and producing properties for acquisition and disposition. The firm has extensive experience in the Northern Rocky Mountain Region with additional experience in the Paradox, Illinois, and Los Angeles Basins, as well as the Mid-Continent Region. We have also evaluated basins overseas.




Recent Studies Include:

Regional Stratigraphic Studies for the Niobrara, Mowry, Shannon, Sussex, Parkman and Teapot Formations in the Powder River Basin

Regional Stratigraphic Studies in the DJ Basin including the Niobrara

Powder River Basin Coal Database

    17,000 data points

    ~80,000 tops and bases of coals (99% picked by one geologist = excellent internal consistency)

    most coals > 20 feet thick correlated

Goolsby, Finley & Associates, LLC. has extensive experience in vertical and horizontal well site supervision for both conventional wells and coal bed methane wells. During the past six years, the firm has continuously provided well site geologists to companies drilling both conventional and coal bed methane wells. Because of our experience with local geology and understanding of field operations, we have the ability to provide necessary support to field personnel to enhance their ability to make proper geologic interpretations, thereby minimizing adverse economic impacts caused by geologic uncertainty.



We have training and experience in advanced log interpretation techniques in both clastics and carbonates. When possible, the firm uses an integrated approach, combining log characteristics with core and sample characteristics, to provide a customized interpretation based on observed data. In addition, we analyze nearby production to better aid in casing point decisions on exploratory and development wells. The firm writes its' own log analysis algorithms, allowing complete understanding, customization and control over any analysis. Past projects include analysis of Lodgepole, Mission Canyon, and Winnipeg production in the Williston Basin, and Muddy, Minnekahta, and Minnelusa production in the Power River Basin. Examples are available upon request.



We have extensive experience in providing expert geological testimony to the Wyoming Oil and Gas Conservation Commission, where we have an excellent reputation. Our office is located two buildings away from the Commission. The geologists of Goolsby, Finley & Associates, LLC. are licensed by the State of Wyoming to practice geology and certified professional geologists by the American Institute of Professional Geologists and the American Association of Petroleum Geologists.



Goolsby, Finley & Associates also conducts property and estate evaluations. Results of the evaluations are used for acquisition/disposition determinations and for tax evaluation purposes. Recent evaluations include several coal bed methane projects for acquisition and disposition and property and estate evaluations for holdings in Wyoming, North Dakota, Utah, West Virginia, New Mexico and other states for tax purposes.
