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, with drilling now completed 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 are highly encouraging, identifying multiple potential hydrocarbon zones in the Tertiary with very good porosity and permeability. The intention now is to concentrate efforts and resources on completing and testing the well.  Please see ‘News’ for updates on operational progress.

US Oil has been awarded Permits to Drill by  federal and state permitting authorities for its Eblana-3 and Eblana-6 wells.  A third application has been submitted and is currently in process. The required bonds have been lodged for the two permitted wells.

The lease area
Through its wholly owned subsidiary, Major Oil International LLC, US Oil holds a lease acreage of 41,860 acres (approx. 169 sq. km.) in Hot Creek Valley, Nevada, including recently acquired leases totaling 19,639 acres (additions subject to final official ratification).

Hot Creek 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.

US Oil surveys have identified five large possible hydrocarbon-bearing structures on its acreage. In addition, preliminary results from a December 2017 geochemical survey 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, requiring no fracking,  and with extremely low uplift costs. In the present environment of relatively low oil prices the potential exists for a highly competitive opportunity. In addition, the currently depressed price of drilling and services offers a valuable window for cost-effective operations.
