PROJECT EXPERIENCE
Fidelity Exploration & Production:
• Managed the acquisition of seven 3D seismic programs totaling 390 square miles of 3D data.
• Paradox Basin: Licensed and oversaw reprocessing of over 1,250 miles of 2-D data. Integrated with existing 3-D data to define structural elements of the basin. This work lead to the understanding of how fractures were generated in the Paradox formation and the identification of multiple Leadville prospects. Oversaw the design, permitting, acquisition of two 3-D surveys on BLM lands. Both require the development of an Environmental Assessment. Interpreted these along with other 3-D.s to identify and propose prospective Cane Creek horizontal wells. Two of the wells drilled have an EUR in excess of 1.0 MMBO. Steered horizontal wells in the Cane Creek interval of the Paradox formation.
• Hartville Uplift: Licensed and oversaw reprocessing of over 400 miles of 2-D data. Interpretation of these data plus an existing 3-D resulted in 13 prospects in the Leo and Canyon Springs formations. Planning and managed a 3-D Vibroseis survey the lead to the proposal and drilling of two exploratory wells.
• DJ Basin: Oversaw the design, permitting, acquisition of two 3D surveys totaling 133 square miles. Interpreted them to identify geohazards and areas of potential fracturing. Four unsuccessful wells were drilled.
• Big Horn Basin: Managed the acquisition of a mixed source 28 square mile 3-D survey on BLM lands in Carbon Co., MT. The permit was conducted under a categorical exclusion from the BLM. Generated three stratigraphic prospects from the data. Exploratory wells have not been drilled.
