Play Analysis: A Systematic Approach in Pemex

Exploration as a complex and multidimensional task requires time – spatial analysis of physical elements and thermo dynamical processes which together constitute the “Petroleum System“ that must be iteratively studied from basin to reservoir scale as long as new data and technology are integrated.

Oil exploration requires multiple and various different kinds of data both direct and indirect which must be collected, processed and interpreted by different disciplines specialists to elaborate predictive geological models for Petroleum System in order to estimate both elements occurrence probabilities and volumetrics.

Composite Risk Maps are the final product from Exploration studies. These resulting maps support and guide both technical and business exploration decisions.

In order to standardize practices and products to facilitate “Decision making“, Pemex has implemented Play Fairway Analysis approach. Simultaneously we have developed a probabilistic tool named CERPlay for volumetrics at play scale and the SIMAREP tool used to automatically generate Risk Maps from the geoscientist teams original interpretations.

This approach has been complemented with a digital cartographic and data repository tool based on Geographical Information System used to assure information integrity, to promote team communication and managing knowledge and, finally the portfolio tool used to extract data and information from master data base to create different scenarios based on multiple constrains from top management level.

As a whole this system aims Pemex to reinforce exploration structural aspects related to data, practices, people, technology and knowledge in order to promote team work focus on a full cycle and value generation approach.
