Abstract

The ever-increasing need for resilient strategies demands the supreme understanding of business uncertainties and the execution risks. For the National Oil Companies like, ADNOC, the annual reservoir performance review (ARPR) is a process of paramount importance, as it provides a holistic overview of the reservoir performance status for each ADNOC field on yearly basis. It unfolds the subsurface performance issues, uncertainties and risks, and steers the decisions of Business Plan sanctions.

The ARPR execution demands a tremendous amount of time and effort to assimilate information and create a consolidated decision support package. In the absence of an automated process, the creation of insightful analytics, proper tracking of actions and maturation of value-driven opportunities become unmanageable. Thus, the automation of the process asserted to demonstrate a significant reduction of the data preparation time, increased multidisciplinary collaboration, centralized data archiving and integrated dashboard generation.

A multidisciplinary team of ADNOC's subject matter experts joined forces to develop a fit-for-purpose automated solution (i-ARPR) that underpins a sophisticated subsurface knowledge bank that leverages advanced analytics and digital technologies to integrate key reservoir performance parameters automatically and provides insights to support crucial business decisions. It allows users to collaborate via an automated guided web-based workflow to build the analyzed content for the ARPR report for a given Field, using data previously loaded and approved. The content is built bottoms-up from a defined list of Elements (Plots, Tables, Images and Text) along with analysis and insights contributed by Subject Matter Experts (SME's), into sections of the report that are collated and further expanded with insights and conclusions by designated Sections Editors.

The solution enables assigning tasks to users at various supervisory and coordinating levels through an automated governance system. It provides means to monitor the progress of the work, approve the content of Elements and Sections, and review the concatenated ARPR document for final approval. All the integrated analyses get stored into the corporate repositories for any future utilization in data mining and advance analytics workflows.

The automated solution (i-ARPR) has enabled efficient data gathering, and its visualization has fostered multidisciplinary collaboration and has provided 66% more time to the engineers to analyze the information for identifying risks and opportunities. Over $50 Million OPEX saving is estimated during the first three years of the project implementation in 17 upstream assets within the ADNOC Group.
