Reduce Collision Risk and make Informed Decision with Cost Effective Well Placement Database for Abu Dhabi Exploration Blocks

Abstract

Abstract The well-collision-avoidance management principles in this paper are a summit of the work and guidelines of industry specialists from both oil operating companies and directional drilling service providers. This well-known subject in the drilling domain, the objective is to drive further the standardization of the collision avoidance rules and process in Abu Dhabi and throughout the industry to improve the efficiency and reduce the related errors. The results of an unplanned crossing point with an existing offset well can extend from economical loss to a blowout and HSE disasters and even loss of life. well-collision avoidance principles include rules that decide the allowable well separation, directional drilling, and surveying planning in addition to quality check/ quality control procedures. The appropriation of a particular minimum-allowable separation rule does not guarantee a low collision probability. Numerous other components contribute, such as the level of compliance by office and field personnel with collision-avoidance standards and procedures, and the quality and accuracy of the directional surveys database. All these variables are linked and affect the collision risk rate. The paper is split into many sections, each managing a specific component within the collision-avoidance process. Illustrations are displayed to highlight a good implementation of the process. This adjusted approach will improve the current practice by cover few gaps as currently only ADNOC Drilling Code of Practice Volume 3 Chapter 08 – Collision Avoidance (ADCOP V3CH08) is the unified document used by the operating companies as reference to drill safely in Abu Dhabi, but each company has it’s specific database without common database among all companies drilling in the same city.
