AbstractAn integrated analysis of technical information from 459 wells that were shut in or having production problems within five Integrated Business Units in the Southern Region of PEMEX E&P, identified production increase opportunities of more than 145,000 STB/D of oil and 323 MMscf/D of gas. This paper presents the applied methodology and the results obtained from a project based on well management to optimize the recovery of hydrocarbons of the identified opportunities within these business units with minimum investments. The successful implementation of this project was based on the careful selection of highly qualified technical personnel that formed the nucleus of the working multidisciplinary teams that contributed to the increase of well productivity from the selected fields. The implementation of the concept of team work coupled with the application of selected technologies to identify and exploit potential opportunities made it possible for these business units to increase the production of crude oil over 67,635 STB/D and gas to over 111 MMscf/D from workover of 179 wells within 9 months thus achieving a production increase of 7.95 MMSTB of oil and 12.8 Bscf of gas. This increase in production made possible for this region to maintain a production plateu of 500,000 STB/D and 450 MMSCFD, offsetting natural production decline and loss of production due to a strong water invasion of wells. A profit/cost ratio of 15.1 has been obtained. In addition to the value added of production increase through this visionary management approach, the following benefits were obtained: learning and applying the team work approach of well productivity, adaptation to a new cultural change of working as teams to solve difficult problems, training and transfer in diverse methodologies, and software technologies from the interdisciplinary teams to the technical personnel of PEMEX E&P, and specific well data information certified that can be used to evaluate diverse reservoirs studies.
