Integrating Exploration and Appraisal into one regulatory phase

The current situation of crude oil prices and the COVID-19 lockdown make 2020 one of the most critical years to  improve the oil and gas industry: operation flexibility, cost reduction, and regulatory improvements are pressing  more than ever. Mexican E&P regulatory system is divided into three main stages: Exploration, Appraisal and  Development. These stages are sequential and all of them are regulated through a technical document (called Plan or  Program) subject to CNH’s approval. The three documents have activities and investments that, even if they may be  related, are circumscribed to only one of the three documents, either the Exploration Plan, Appraisal Program or the  Development Plan… BUT IS THIS THE BEST WAY?

From a technical and economic point of view, an E&P project integrates different approaches, activities, scopes,  investment, and strategies. Operators and governments’ objective is to get commercial production at the lowest  cost possible to maximize profits during the life of the project. With this in mind, in order to start production as soon  as possible there is an important opportunity to optimize pre-development activities, like the ones of exploration  and appraisal periods.

In Mexican regulation, unfortunately, having Exploration and Appraisal periods separated, slows down the  development of activities. For instance, it is challenging to get approval for an appraisal well that has a double  purpose:
i) delimiting a discovery, and ii) looking for a deeper potential productive formation. The challenge consists  in the Operator documenting the same approved well in both the Exploration Plan and the Appraisal Program; and to  (somehow) distribute budget and investment in separated Exploration and Appraisal projects.

In this way, the current regulation forces Operators to make two different approvals (Exploration Plan and Appraisal  Program); which translates in double time and double regulatory costs for similar objectives, lower flexibility, longer  project durations, and complicated logistics and supervision.


The Hydrocarbons Law only recognizes the obligation of presenting two technical documents: the Exploration Plan  and the Development Plan. The need for an Appraisal Program arises from the Contracts for Exploration and  Extraction (“CEE”) and the Plan Guidelines. According to the above, the Exploration activities and the Exploration  Period may also consider appraisal activities that are mainly characterization and delimitation of a Discovery;  however, this is only by definition.

The regulation only recognizes one scenario in which the Appraisal Program integrates into the Exploration Plan, and  one in which the Appraisal Program is not necessary:


Integrating Appraisal activities into Exploration and Development Plans will allow to:

  • Reduce time to get to the development stage or to determine a non-commercial discovery.
  • Lower regulatory cost.
  • Increase operational flexibility (mainly for well drilling).
  • Align technical and regulatory approaches.

These modifications will benefit both, government and Operators. The Appraisal Program can be maintained, but  regulation would allow flexibility in documenting appraisal activities in the Exploration Plan. In this way, Operators  can present more comprehensive projects lowering the need for additional documents from operational changes.

Given that appraisal activities are also used to support a Development Plan, this proposal may be applied to  Development regulations with specific benefits, that will be further discussed in a separate publication.



For this to happen, a modification of the Plan  Guidelines is needed (as well as the related costs  regulations of the Mexican Petroleum Fund and  the Ministry of Finance). The main changes  would be as follows:

  • Allowing the integration of Appraisal  activities into Exploration Plan: the Appraisal Program will no longer be an independent  administrative procedure. Depending on the  maturity level of the Contractual Area or  Entitlement, the Exploration Plan can be  approved with appraisal activities, and any  change in the exploratory strategy may  include additional appraisal activities and  objectives (including the ones derived from a  discovery).
  • Shared objectives: the activities considered in  the Exploration Plan (including appraisal  activities) will have exploratory and appraisal  objectives, so the operation becomes more  flexible and efficient.
  • Modifications to the Plan: the modification  assumptions for the Exploration Plan and the  Appraisal Program are already very similar, so  theycanbemerged; andonlyincludeonemore  assumption referring to the addition of  appraisal activities derived from a discovery.
  • The Appraisal Program does not disappear:  the CEE considers the Appraisal Program and  Period as an obligation, so the Plan Guidelines  shall specify that the Appraisal Program and  Period will be part of the Exploration Plan. The  Exploration Plan shall be valid through the  Exploration and Appraisal Periods, according  to the CEE.
  • Cost reporting: given that Exploration Plan  annual budget will include appraisal activities,  the allocation of investments will become  easier and flexible.
  • Regulatory burden: the Operators will only pay  for an Exploration Plan approval or  modification. The annual supervision  payment will be lower and supervision by CNH  will be easier.
