06 September 2011 - DJ U.S OIL And GAS Plc - 3D Passive Seismic Results Confirm Substantial Updip Reservoir on Lease Area

TIDMUSOP   3D PASSIVE SEISMIC RESULTS CONFIRM SUBSTANTIAL UPDIP RESERVOIR ON LEASE AREA   6 September 2011                                                  U.S. Oil and Gas Plc.                                             ("US Oil" or the "Company")                    3D Passive Seismic Results Confirm Substantial Updip Reservoir on Lease Area   U.S.  Oil and Gas plc (PLUS: USOP), the oil and gas exploration company with its main asset in Nevada, USA,  is pleased  to announce the results of its 3-D Infrasonic Passive Differential Spectroscopy (IPDS) survey recently completed over the whole of its lease area.

A  report  prepared  by  Geodynamics Research confirms a large hydrocarbon anomaly consistent  with  previously reported  geochemical  survey results and other data sets.  The anomaly covers more than  10  sq.km  and  shows consistently  high  Reservoir Hydrocarbon Indicator (RHI) readings.  The hydrocarbon pool sits  updip  and  is wholly contained within the lease area, while the source kitchen is underneath or just down-dip nearby.

US  Oil  has identified up to ten drilling targets over the whole lease area.  Of those ten, the most promising three  are superior to the best target shown by the earlier 2-D IPDS survey using the RHI scale carried out  on part of the lease area and reported in an earlier RNS dated 26 February 2010.

Work  continues to complete the process of estimating recoverable oil in place for the accumulation identified. These  estimates  will  incorporate all data sets collected so far plus petrophysical  evaluation  of  recently acquired  digitized   well log data from 11 wells in nearby Railroad Valley.  The final analysis is currently being  carried  out and will form the basis of a Prospective Resources report to be completed  in  due  course. Meanwhile, completion of administrative procedures and ground operational plans in relation to  the Company's three-well drilling programme are continuing as planned.

US Oil CEO Mr. Brian McDonnell said: "The 3-D IPDS survey results have exceeded our expectations.  The new data has identified drilling targets even more promising than before, and although this demanded considerable extra time in data  analysis  and refining our model, we believe the result will be to minimize  uncertainties  and further reduce the exploration risks associated with our forthcoming drilling campaign."



On  15  August 2011 it was announced that Geodynamics Worldwide Srl had received 98,923 ordinary shares in  the capital  of  the  Company ("Ordinary Shares") from the Company's treasury, in lieu of payment  in relation  to seismic  surveying work undertaken.  Geodynamics Worldwide (marketing) and GDR (technical)  are  two  separate legal entities.  US Oil's Exploration Manager, Dr. Karim Akrawi, is currently General Director of  Geodynamics Worldwide Srl.  On 21 July 2011 it was announced that Dr. Akrawi had received 100,000 Ordinary Shares from  the Company's treasury, in lieu of payment.
