U.S. Oil & Gas plc was formed to exploit the potential for substantial conventional oil and gas finds in onshore North America, using the most advanced technology available.


Eblana #1 well, Hot Creek Valley

Current activities
The Eblana-3 well spudded at 13:30 PST on April 17th 2018 and drilled to a depth of 8,200ft. The well is situated updip of the Company’s discovery well Eblana-1, and is on the same structure. Eblana-3 is a vertical well.  Wire-line and mud log results were highly encouraging, identifying multiple potential hydrocarbon zones in the Tertiary. Oil of API 34.5 flowed to the surface. The intention now is to concentrate efforts and resources on establishing a commercial flow from one or more zones. Please see ‘News’ for updates.

The lease area
Through its wholly owned subsidiary, Major Oil International LLC, US Oil holds a lease acreage of 73,725 acres in Hot Creek Valley, Nevada. The Valley is 35 miles west of Railroad Valley, a location that has produced more than 40 million barrels of oil to date. Analysis of oil flowed by the Company’s Eblana-1 well shows it to be of similar composition, and most likely from the same Chainman Shale source rock, as that in Railroad Valley. Results from Eblana-3 now support this finding.

US Oil surveys have identified multiple large possible hydrocarbon-bearing structures on its acreage. In addition, results from geochemical and magnetic surveys indicate a high potential for hydrocarbons throughout the Hot Creek Valley concession and confirms the Company’s view that its leases cover a major oil system.

Resource Estimates
On February 2, 2017, on the basis of all available data, including Vertical Seismic Profile (VSP) data collected from the Company’s Eblana-1 well and processed by Halliburton, and after a review of petrophysical parameters, Baker Hughes Inc. reported revised Original Oil-in-Place estimates for the Tertiary zones in the area updip to Eblana #1 as follows:

The Eblana #1 exploration  well,  drilled by U.S. Oil’s wholly owned subsidiary Major Oil International LLC, identified  nine  large  potential oil reservoir intervals and  associated  high fracture  zones before reaching its target depth of 8,550 feet.  Testing confirmed two producer zones, approximately 150 feet cumulative net pay, and identified light, sweet oil of 33 and 28.5 API.  Oil produced had a high water cut and did not flow at commercial rates due to the well encountering the oil/water transition zone.  The discovery was confirmed by an independent Competent Person’s Report prepared by Forrest Garb & Associates.

Halliburton VSP study
In 2016 the Company contracted Halliburton to carry out a Vertical Seismic Profile (VSP) survey based on US Oil’s Eblana #1 discovery well, and Baker Hughes (BHI) to carry out structural modelling based on all the available data including VSP. The purpose of the structural modelling was to reduce risk as far as possible before the Company carries out its planned drills. In addition, Baker Hughes calculated the revised Oil-In-Place estimates reported above for the Tertiary Structure updip of the Eblana #1 well. These estimates do not include the Palaeozoic strata, which may also be highly prospective.

Conventional play, low uplift costs
The Hot Creek Valley discovery is potentially a conventional onshore resource with extremely low uplift costs.
