Orinduik 3D seismic identifies ‘potentially sizeable structures’ offshore Guyana

Eco (Atlantic) Oil & Gas Ltd. says it is encouraged to date by the quality of data received and interpretations being made based on the 3D seismic survey conducted on the company’s Orinduik Block, offshore Guyana. Data collected and analyzed so far, the company says, has firmed up the previously outlined targets as well as identify new additional potentially sizeable structures.

Eco’s partner and Block Operator Tullow Oil contracted PGS Geophysical in the UK to process the 2,550 sq km 3D seismic data acquired for the partnership by Western Geophysical.

Eco has recently received the latest set of deliverables in relation to the 3D seismic survey including PSTM Angle Stacks and associated Inversion products that better define the geological lithology of the play, provide a better imaging of the sands, and allow the interpreters to more closely define target fluids. Tullow and Eco have begun their review and interpretation of this latest data set, which has also been copied and forwarded to Total E&P Activités Pétrolières (“Total”). This is in addition to other previously received sets of filtered PreSTM Fast Track and data sets from Tullow, which in turn, have also already been received by Total for their review, in accordance with its 25 % farm-in option agreement and to help expedite the farm-out process.

Eco said the data is also being interpreted in parallel by its consultant Gustavson Associates for the purpose of producing an Independent Resource Report in accordance with AIM and TSX guidelines. Tullow has advised that Intermediate Kirchhoff PreSDM from PGS is anticipated to be completed the last week of May, which in turn will enable the Resource Report to be concluded and published.

Commenting on this latest development, Colin Kinley, Chief Operating Officer of Eco Atlantic said, “The Company has the benefit of a significant 2D data set that ties into areas of the recent Exxon discoveries offshore Guyana, which are now estimated to exceed 3.2 Billion barrels. This data ties back into our recently acquired 3D seismic and that has allowed us to better track the age and the quality of the sands and mechanisms that create the hydrocarbon traps. We interpret the charge from the source rock migrating up-dip and being trapped at various locations on the foreslope which is supported with each Exxon discovery downdip of us. This in turn, is giving us a better understanding of the features that allow those same hydrocarbons to feed up into the channel and fan systems on our block.”

He said results to date have led the Company to draw initial interpretations of the thickness and quality of sands which appear to be very promising.  “We are seeing many more interesting features and targets across the Orinduik Block. Given these results and the need for a more expanded and detailed interpretation, we have taken longer than we originally envisaged to complete the processing with good merit.”

The existence of multiple exploration targets on the block will be very significant, Mr. Kinley said, not only in the resource numbers, but also in the economics of this shallow water play, “in terms of both drilling and potential development for our partnership, and for Guyana.”
