DENVER, Nov. 29, 2016 /PRNewswire/ -- The Oxford Institute for Energy Studies (OIES) has published PetroNerds' new research paper, "Unravelling the US Shale Productivity Gains," authored by PetroNerds co-founders Trisha Curtis and Ben Montalbano. "Unravelling the US Shale Productivity Gains" examines the significant year-over-year well productivity gains that have been generated in several prominent US shale and tight oil plays since the beginning of the oil market downturn in 2014. PetroNerds combined evaluations of individual wells, research of company behavior, disclosures and well performance, as well as play-wide well performance analytics to generate the data and analysis presented in this paper.

The paper argues that the shale oil sector is becoming far more resilient and nimble than many had expected and productivity continues to grow even in a low price environment. Looking ahead, there is a lot of running room left in the unconventional oil plays. The paper argues that high grading to core areas is an important factor, but it does not explain the entirety of productivity gains. While there has been no single transformative technological development with regards to shale oil development over the past several years, there are signs that shale oil is moving from a manufacturing process, in which producers simply repeat what worked on the previous well, to a more thoughtful well researched program, particularly in the areas of completion designs, well spacing, better rock analysis and proper lateral placement, which have all been contributing to well productivity gains. This paper is a synthesis of much of PetroNerds' ongoing research into US shale and tight oil well productivity, play economics, competitor analysis, and asset evaluations.
