Derek Oil & Gas Receives Evaluation Report on LAK Ranch Oil Reserves & Oil-In-Place Estimates |
(Vancouver, B.C.; May 5, 2004) Derek Oil & Gas Corporation (“Derek”) reported today that a new independent engineering evaluation of the LAK Ranch oil project in Wyoming identifies in excess of 190 million barrels of oil “in place” in two potentially productive horizons.
The new study, byPetrotech Engineering Ltd. of Burnaby, British Columbia, is based on historic data and a recent development plan produced by Derek’s joint venture partner and project operator,Ivanhoe Energy(TSX-IE). Petrotech verified the results of a preliminary plan byIvanhoe to develop a limited area of the LAK Ranch lease using Steam Assisted Gravity Drainage (SAGD) technology.
The report notes that theIvanhoe production model for the Lower Newcastle Channel Sand forecasts an ultimate recovery of 13 million barrels of oil from an estimated 20 MMBO of oil-in-place under approximately 450 acres of the 7,500 acre lease. This model performance is achieved by a SAGD development pattern utilizing 21 new horizontal producers with 5 new vertical injectors for each producer. Gross capital expenditures are projected to be US $35million.
The upside potential of an extended full development is dependent upon the amount of additional productive acreage on the lease that can be economically developed using SAGD.
Commenting on the report,Derek President Barry C.J. Ehrl, said the target size, reserve and production potential could change significantly as new information from a planned 3-D seismic program is evaluated and as continually evolving adaptations to SAGD technology are in introduced at the LAK Ranch.
“Industry observers have projected that enhanced oil recovery techniques such as Steam Assisted Gravity Drainage can lead to ultimate recovery of “oil-in-place” in the 50% to 70% range. Such technical applications could have a dramatic impact on the productivity of the LAK Ranch”, Ehrl said.
ThePetrotech report uses the definition of reserves category from the Canadian Oil and Gas Evaluation Handbook and conforms to National Instrument NI 51-101 (Standards of Disclosure for Oil & Gas Activities).
