CalEnergy's Pryderi-1 well comes up dry

IPB Petroleum advises that the Pryderi-1 exploration well in WA-424-P (IPB 75%, CalEnergy 25% and Operator) reached a total depth of 694m (RT) in 12.25” hole late afternoon on 15 November 2014 with no moveable hydrocarbons being encountered. Despite some residual oil shows encountered while drilling, the target reservoir at Pryderi is interpreted to be water bearing. Operations over the next 48 hours include the planned plugging and abandoning of the well. IPB now intends to complete further interpretation and analysis on the results of the well to gain an improved understanding of the remaining prospectivity within the permit, which includes the existing Gwydion oil discovery (2C Contingent Resources of 5 MMbbls -100%). IPB’s Managing Director Brendan Brown said “Although the results of this first well are not as predicted, we know that oil is present in this part of the Browse Basin and the data from this well will help us in our ongoing exploration efforts within the permit. IPB remains confident that the company’s existing acreage offers significant hydrocarbon prospectivity in a basin that is a focal point for so many multinational energy companies.” IPB would like to reassure shareholders that the evolution of successful small exploration companies often involves dealing with exploration risk outcomes and pursuing multiple options. The directors aim to also continue with their stated strategy which includes the examination of complementary opportunities, with the ultimate objective of adding to the company’s current exploration portfolio.

The Pryderi-1 well was spudded early morning of 9th November. Pryderi-1 is a relatively shallow well and based on the current well schedule IPB estimates that the target reservoir will be intersected later this week. Over the next 24 hours, planned operations include the commencement of drilling the 17.5 inch section of the well.
