Changing The Dynamics of Performance Management - The Micro KPI Concept

The Drill Well on Paper (DWOP) exercise is an accepted tool for use in planning an offshore well, and in post-drilling analysis to demonstrate real and potential efficiency gains when comparing latest generation drilling and floater designs. However, given accelerated advances in drilling systems and operational practices, does the DWOP methodology of strictly analyzing fixed line-item data adequately capture non-apparent flat time and enhance overall operational efficiencies? This paper explores areas where the traditional DWOP may not clearly reflect the efficiencies and HSE gains intrinsic of the latest generation drilling environment, and makes the case for transforming to more of a project management-like approach. For instance, efficiencies demonstrating reduced well delivery days would logically translate into a corresponding reduction in injuries/man-hour, but results of that accepted metric are not recorded in a post-well DWOP. Additionally, despite simultaneous rig operations, often denoted as off-line activities, the typical DWOP only looks at one operation, or line item, at a time. Thus, any efficiencies or bottlenecks in these parallel operations are often neither identified nor recorded in the DWOP. The authors will present direct comparisons to illustrate how a typical DWOP exercise may not capture and detail the consequential reductions in lost time incident rates (LTIR), flat times and invisible lost time (ILT) achievable with advanced rigs and drilling systems. Standardized robotic pipe manipulators, floaters with increased storage capacity for casing and other consumables that reduce supply vessel requirements, and new rig designs and/or moon pool dimensions that widen the operable window and reduce weather-related downtime, are among the efficiency drivers the authors suggest should be reflected in a DWOP analysis. Additionally, improved operational practices, like pre-installation of casing centralizers, and automated pipe tally and monitoring systems contribute to improved efficiencies and economics, which further justify modifications to the standard DWOP thought process. This paper aims to broaden the readers our understanding of how deepwater rigs can be assessed with respect to efficiency and HSE gains; thereby, leading to a rethinking of the current methodology used in rig comparison DWOPs.

Drilling a well is comprised of multiple activities which are linked to the well objectives and requirements set in the design phase. Some of the activities have short term impacts on the well such as logging a section etc., and some of the activities have long term impacts on the well such as cementing, wellbore accessibility etc. It is quite important to list the activities based on their impact on a well and rate them individually to get the overall impact on the objectives of a well by these activities. Conventionally a well quality score was reported 6-12 months after a well was completed. The quality cycle to improve the performance of a well became ineffective and irrelevant due to late reporting. The results of the activities of a completed well were so late that many wells had been drilled and completed during the reported period. First, this major flow turned the existing Well Quality KPIs into laggard KPIs, which were not contributing to enhancing the Quality of a delivered well. Second, the well quality score was distributed among four different categories where Well Integrity was an isolated category, and a well integrity issue has minimum impact on overall well quality scoring. Third, the scoring guidelines were very generic and were depended on the evaluator judgment. A lack of verification of the results was also evident during KPI reporting, which made the KPIs score skeptical and unreliable. Fourth a fixed scoring structure was used to evaluate all type of wells at the same scale. Such as the scoring of a complex well was treated the same manner as a scoring on a workover well. Last, some activities were ignored in the well quality scoring such as Coring Quality, minimum Well Integrity requirements etc. The overall score does not represent the actual picture of a well using existing Well Quality KPIs, which was impacting the overall project quality score. A new approach was adapted to capture the well quality score right after a well is delivered so that improvement ideas can be implemented in the current drilling wells in the execution phase and coming wells in the design phase without any delays. The quality cycle was improved resulting in shorter well duration with lesser well integrity issues. A new weightage system was introduced to capture all activities in a well, where these activities are evaluated individually. Scoring criteria for each activity is defined clearly. Based on deviation from the planned activity, the actual score is recorded accordingly by the user. Later these activities are verified by the end users, so verification is enhancing the trust as well the validity of a lesson learned. Users and end users are connected at an early stage after a well completed to capture the feedback. Improvements get quickly implemented as the quality cycle is short and quick. The new scoring method introduced a wide range of Well Integrity checks based on rigorous and clear guidelines, where failure to meet key well integrity policies can result in nulling the overall score of a well. New well quality scoring guidelines provide a clear and efficient approach to score the key performance indicators of a well at the right time. Consistency in scoring, timely reporting and right weightage for well quality scoring results in high quality well programs, application of fit-for purpose technologies and better knowledge transfer among team members.
