Abstract: In the Oil and Gas industry, real-time mud logging measurements have been used since the early 70''s with a wide range of applications. The advancement in mud logging measurements is focused on optimizing drilling operations. To reach this goal the historical data of the correlation wells represents a valuable source of information, allowing decrease the uncertainty associated to well planning and execution that can be maximized under technical and managerial circumstances. This paper reports the experiences of real-time advanced logging information integration from the well in progress with the historical data of the correlation wells and how this allowed taking preventive decisions to optimize the density window range more accurately, to evaluate operational parameters and to use the best technologies according to the modeled best practices, to evaluate trends. All this is in order to issue alerts, recommendations, proposal, and mitigations procedures before and during the drilling operations to allow the decision-makers to reduce the NPT and the possible negative HSE impact. The process involves emerging technologies enabling to collect and interoperate data collected by different operators in a transparent way into a knowledge repository that integrates real-time information and offset correlation wells, to analyze and compare the data to the models, to issue alerts and to provide standardized visualization modules in a collaborative environment allowing the decision-makers to reach their goals.
Surface and down hole data logged from offset wells have always proven vital to optimize the efficiency and success of the current well being drilled. To solve this problem, which was first observed in a Real Time Operation Center (RTOC), the need arose to make a streamlined and better integrated well analysis that would allow preventive measure to be taken in real time by considering the events from the offset wells, Pore Pressure and Fracture Gradient.
