Considerations on well drilling authorizations


Up to date, only 17 of 139 committed wells have been completed: 16 appraisal or production wells  (rounds 1.2 and 1.3) and one exploratory (Talos’ Zamma-1), which discovered a 1,800 MMboe shared  reservoir with PEMEX.

The remaining 122 committed wells are distributed among 38 contracts where 34 have an approved plan  (exploration, appraisal or development). Out of these, 28 have not started drilling any single well, despite  having an approved plan for more than 2 years.


In our experience, this is often due to a poor regulatory compliance, lacking a comprehensive approach of  the technical and environmental requirements. As a general suggestion, we recommend considering the  following essential elements in the preparation of requests for drilling authorization:

  • Include the well to be drilled in an approved plan (Exploration, Appraisal or Development).
  • Explain each stage in the Drilling Program including contingency scenarios.
  • Schedule of activities of Drilling, Completion and Abandonment  and include estimated total cost.
  • Feasibility analysis of Drilling and Completion according  to operator’smethodology.
  • Present a third party certification of: drilling program, risk assessment  and mitigation plan, among others.

Additionally, it is necessary to consider updating other obligations like ASEA’s MIA, SASISOPA, Environmental Risk Assessment, permits for waste management, among others.

As a result of the first (9) Mexican bidding  rounds, the awarded companies committed  to perform, at a minimum, a broad variety of  activities where drilling wells represents the  main investment.
