Decklar Resources Inc. announced an update to operations at the Oza-1 well re-entry at the Oza Oil Field in Nigeria, being performed by the company’s wholly owned Nigeria-based subsidiary, Decklar Petroleum Limited.

Re-entry operations at the Oza-1 well site continue to progress with completion of critical initial work activities including pulling the existing tubing and the 5 ½ inch casing that was inside the 9 ⅝ inch casing. The 9 ⅝ inch casing has been scrapped and circulated clean and over to brine completion fluid and a cement bond log has been run to confirm the integrity of the wellbore and cement behind the casing. Cased hole reservoir logs have been completed and analyzed and confirm the expected characteristics of the zones targeted for testing. Surface testing facilities and equipment are currently being installed, and it is anticipated that testing of the L2.6 zone will commence early next week. Perforation operations will begin with a testing tubing string run with straddle packers to enable testing of the three isolated individual zones that will be tested. Production testing operations are planned for the three known oil-bearing zones (L2.2, L2.4 and L2.6), and each targeted zone will be production flow tested independently. All test volumes produced will be exported and sold through the existing production facilities and pipelines. Once testing of all three zones is completed, it is anticipated that a final dual-tubing string completion will be installed, and two of the three zones tested will be placed into production based upon successful testing. All necessary approvals and permits are in place for the well re-entry, testing and completion.

As previously announced, once the Oza-1 re-entry is complete, the drilling rig is then expected to be skidded on the same drill pad as the Oza-1 well to a new drilling slot and a horizontal development well will be drilled in one of the three zones tested in the Oza-1 well. It is anticipated that this well will then be placed on production upon successful testing and completion. The Oza-1 well and new horizontal development well are expected to generate significant production levels and generate cash flow in a short time frame utilizing the existing infrastructure in place. The Oza Oil Field development is planned to then continue with one or two more re-entries on other existing wells and an additional development drilling program with a potential for eight to ten wells to be drilled to achieve full field development. Additional early production and central processing facilities will be added as required to accommodate increased production levels from field development activities.
