A new onshore Mexico field discovery in the state of Veracruz was reported by Pemex. The estimate of the field in Veracruz Basin at #1-Ixachi is 350 MMboe, and it increases the field’s in-place volume to 1.5 Bboe. According to the company, the results are similar to a previous discovery at #1-Zama. Based on preliminary studies by Pemex, it is considered that this reservoir could be extended farther and possibly double its initial estimated size.
Talos Energy LLC announced details from a second well drilled on the company’s Green Canyon Block 281 project. The #2SS (ST) OCS G33242 hit 90.5 m (297 ft) of net oil pay across two Upper Miocene sands. A sidetrack was drilled to an estimated depth of 6,433 m (21,107 ft) with a true vertical depth of 6,418 m (21,057 ft). Water depth in the area is 838 m (2,750 ft). Block 281 is the company’s Tornado development. The first well on the project, #1SS (ST) OCS G33242, was drilled to 6,326 m (20,755 ft) in 2016 with production from an Upper Miocene zone at 6,099 m to 6,148 m (20,010 ft to 20,170 ft).
GeoPark announced test results from appraisal well #3 Tigana Norte in the Tigana oil field in Colombia’s Llanos 34 Block. The well was drilled to 3,460 m (11,352 ft) and had oil shows in Guadalupe and Mirador. A production test conducted with an electric submersible pump in Guadalupe flowed about 970 bbl/d of 15-degree-gravity oil with less than 0.25% water cut. It was tested on a 32/64-in. choke with a wellhead pressure of 129 psi. Additional production history is required to determine stabilized flow rates of the well. The #3 Tigana Norte is about 690 m (2,264 ft) west of the recently completed #2 Tigana Norte that produced 2.6 Mbbl of oil with less than 0.5% water cut. The appraisal test broadens the Tigana/Jacana oil field play toward the northeastern limits of the Llanos 34 Block. GeoPark is drilling #4 Tigana Norte to further delineate the northeastern boundaries.

Operator Tullow Oil Plc announced updates from its Ngamia, Amosing and Etom appraisal drilling program in Kenya’s Block 10BB. The #10 Ngamia encountered 65 m (213 ft) of net oil pay in the Ngamia prospect. The #11-Ngamia hit 143 m (469 ft) of net oil pay and will be utilized in a waterfl ood pilot test planned for 2018. In the Amosing prospect #6-Amosing hit 35 m (115 ft) of net oil and gas pay, and #7-Amosing hit 25 m (82 ft) of net oil and gas pay. An extensive wireline evaluation program including sampling was performed on all appraisal wells. According to the company, the presence of rift-edge facies has limited net pay. In the Etom prospect in Block 13T #2-Etom fl owed 752 bbl/d of oil from Auwerwer and 580 bbl/d of oil from Lokong. Tullow owns 50%, Africa Oil owns 25% and Maersk Oil & Gas owns the remaining 25%.
