Hydrocarbon Dynamics has acquired 3,459 acres over a portion of Asphalt Ridge in the Uinta Basin in Utah in May and July 2018.
At Asphalt Ridge HCD is targeting the oil sands in the Upper Cretaceous Rimrock Sandstone which is one of several well documented oil sands in Utah. According to the Utah Geological Survey Asphalt Ridge contains oil sands with over 1 billion barrels of measured oil in place over an area covering approximately 10,500 acres.
Previous operators in the region have drilled several exploration wells in Indago’s acreage. HCD has been able to assess some of the information from earlier wells which has assisted in understanding key elements of the play and the region’s prospectivity. In addition, several operators have mined asphalt from the Mesaverde Group at outcrop and in the shallow subsurface to the east and northeast of Indago’s leased acreage.
The information from previous operators has demonstrated an oil saturated reservoir approximately 90-175’ (27-53 metres) thick, at a depth range of between 200-3000’ (60-914 metres).
Based on previous results published on the Utah Geological Survey website of more than 330 core samples from six test wells drilled in the sections adjacent to HCD’s acreage, the target zone has reported reservoir properties that include an average porosity of 30.3%, average permeability of 524 millidarcies, oil saturation of 65.6% and an oil gravity of 10-140API.

The Company will initially test oil samples from Rimrock Sandstone to both understand the efficacy of HCD’s technology in extracting oil from the sand as well as to assist in the design of a larger appraisal programme. The larger programme will aim to demonstrate the continuity, thickness and amount of oil saturation of the Rimrock Sandstone across HCD’s leased acreage. Tests will also be conducted to determine if Multi-flow can be used to commercially extract oil either via a mining process or if it can reduce oil viscosity to enable the crude to be lifted to surface with conventional oilfield equipment.
HCD will submit results from its initial testing along with historical results and all available well logs to an independent resource assessor for certification including volumetric analysis to verify published information.
