Preparation of well intervention programs using the Podbor GTM digital information system

Abstract

   The use of IT technologies to prepare well intervention programs allowed us to automate the initial well selection processes and make the overall work flow efficient and informative with all the work being done in real time through a web resource. The novelty of this project is that the well intervention algorithms and criteria are integrated in the Podbor GTM digital information system as they are developed. The Podbor GTM system designed on a web resource basis allows users to work online. Thanks to this, the well intervention development process is arranged at a much higher quality level: all calculations are made, information is exchanged and the well intervention decision-making history is stored in a single IT system. The new level of digital asset development capabilities reached through the implementation of the Podbor GTM system increases the efficiency of well intervention operations at the pilot project which is Priobskoye field (South License Area). In 2016, 100 hydrofracs were performed in excess of the business plan which ensured 131 mt of additional production (+54% to the plan). A new historical record was set, which is the involvement of 11% of the existing wells in hydrofrac operations. It is one of the important factors ensuring the effective production of hydrocarbon reserves and allowing us to operate our wells in view of potential geological conditions and technological capabilities. The estimated economic effect from these additional well interventions is: NPV RUB 1,415,158,000; PI – 2.7.
