Talos Energy announces approval of Zama appraisal plan

The approval of the appraisal plan by the CNH is a key approval required to commence the appraisal of the Zama discovery. CNH is currently reviewing the application for drilling permits, which are required to commence drilling operations. Talos estimates that it will spud the first appraisal well, the Zama-2, in the fourth quarter of 2018 and that the appraisal program will be completed by mid-2019.

In addition, the Block 7 Consortium – which includes Talos as the operator with a 35% participating interest, as well as Sierra Oil & Gas and Premier Oil – has entered into a firm contract with a subsidiary of Ensco PLC to utilize the Ensco 8503 semi-submersible rig for the appraisal plan. The contract covers the drilling of two wells, a sidetrack and a well test. The rig is expected to be on location ready to commence operations in November.

The appraisal plan includes three new reservoir penetrations. The first well in the program, the Zama-2, will be deepened by approximately 500 m to test an exploration prospect called Marte, which has an unrisked recoverable resource range between 60 million boe and 150 million boe. The estimated cost to deepen the Zama-2 wellbore for the Marte test is approximately US$10 million gross, with Talos's share expected to be approximately US$3.5 million.

The CNH approved a gross budget of US$325 million for the appraisal plan, which includes approximately US$75 million of contingent operations. The budget includes the cost of drilling the wells, performing a drill stem test to gather information about the reservoir continuity and productivity, hole coring across the Zama reservoir, and collecting a number of rock and fluid samples. Talos expects its net share of the costs to be approximately US$75 to US$80 million for the entire appraisal campaign, before any contingency costs.

President and Chief Executive Officer Timothy S. Duncan commented, "We are very pleased to meet another important milestone with our partners in Mexico, following last week's announcement of the Pre-Unitisation Agreement with Pemex. This approval allows us to maintain an accelerated schedule of investments on the Zama project in Mexico, and begin drilling operations on the appraisal plan by the end of this year. This should allow us to stay on track for our ultimate goal of achieving initial production from the Zama discovery in 2022, thereby providing local jobs, increasing government revenues to Mexico, and materially adding to Mexican domestic production."
