ABSTRACT
When the pandemic COVID-19 erupted and spreaded throughout the world, numerous rules and regulations were implemented to ensure the safety of everyone. The outcome of Covid-19 resulted in a global shutdown, where cases continued to grow rapidly that directly affected the normal processes in all business sectors. While the future is still uncertain, business plan must keep on progressing by managing all the obstacles to ensure the business goal is delivered efficaciously while keeping the impact as low as possible. In the early stage of the outbreak, there was limited knowledge and experience to manage a drilling campaign virtually, to ensure all plans are smooth despite all the restrictions to avoid additional cost and schedule impact to the company. Since the outbreak was quite abrupt, the main challenge faced by the team was to ensure a continuous operation like any other year before but with additional enforcement of stringent COVID-19 SOP and to come up with new modus operandi with stringent SOP at every location. During this pandemic, the operation is exposed to the risk of being on standby mode due to equipment unavailability, unreadiness of manpower or delay in vessel movement. Knowing that drilling operation is so dynamic, that a slight change to the drilling sequence could lead to operation shutdown if the required services are not readily onboard. This uncomplimentary impact is due to the new rules or regulations implemented on the manpower and equipment movement to reduce risk of Covid-19 infection. Therefore, a thorough planning is crucial to ensure the success of operation, in fact a few fallback plans must be in placed to minimize the cost and schedule exposure. This paper will address the challenges in managing equipment and manpower throughout the operation for BX-Project together with the solutions to ensure the governance, rules and regulations of Covid-19 are being followed. The approaches taken during this campaign is used as a baseline to run a drilling operation during Covid-19 pandemic in the upcoming year. Lessons learnt captured from this campaign can be replicated by other projects and finding the more efficient ways to implement the best practices. This pandemic has challenged our perseverance to deliver the project objectives while maintaining the dedication, health, focus as well as creativity to overcome unfamiliar circumstances.

ABSTRACT
PETRONAS completed Well H16 in BS field, East Malaysia with a Digital Intelligent Artificial Lift (DIAL) - an improvement to the current applied gas lift system in the field for production optimization system. This DIAL installation represents the first ever successful installation of the technology in an Offshore oil well for Dual String production. This paper provides the details of the installation planning, designing stages, operational process, well unloading and production undertaken to achieve this milestone. DIAL is a unique technology that enhances the efficiency of gas lift production. Downhole monitoring of production parameters informs remote surface-controlled adjustment of gas lift valves. This enables automation of production optimization removing the need for well intervention which will be challenging in high deviation well (more than 60-degree deviation). With remotely operated, non-pressure dependent multi-valve units, the technology removes the challenges normally associated with gas-injected production operation in a dual completion well i.e., gas robbing and multi-pointing. DIAL introduces a paradigm shift in design, installation and operation of gas lifted wells. This paper will briefly highlight the justifications of this digital technology in comparison with conventional gas lift techniques. It will consider value added from the design stage, through installation operations, to production optimization. Digitization and automation have become the new concepts in managing the operations in order to boost efficiency that reflected in long-term cost savings especially in Operating Expenditure (OPEX). This paper focusses on a well completed in November 2020, the fourth well to be installed with the DIAL technology across PETRONAS Assets. The authors will provide details of the well strategy, installation process and production phases: system design, pre-job preparations, improvements implementation, run in hole and surface hook-up. The results of well unloading while utilizing the DIAL system to start up the well and lifting the completion brine will be explained in detail in this paper. For each phase, challenges encountered, and lessons learned will be listed together with observed benefits. Despite the additional operational & planning complications due to COVID-19 restrictions, the well was completed with zero Non-Productive Time (NPT) and Loss Time Injury (LTI). Once brought online, this DIAL-assisted production well can be remotely monitored and controlled ensuring continuous production optimization, part of PETRONAS' upstream digitization strategic vision. © 2022, Society of Petroleum Engineers.
ABSTRACT
PETRONAS completed well H-X on B field in Malaysia with a digital intelligent artificial lift (DIAL) gas lift production optimization system. This DIAL installation represents the first ever successful installation of the technology in an Offshore well for Dual String production. This paper provides complete details of the installation planning and operational process undertaken to achieve this milestone. DIAL is a unique technology that enhances the efficiency of gas lift production. Downhole monitoring of production parameters informs remote surface-controlled adjustment of gas lift valves. This enables automation of production optimization removing the need for well intervention. This paper focusses on a well completed in November 2020, the fourth well to be installed with the DIAL technology across PETRONAS Assets. The authors will provide details of the well and the installation phases: system design, pre-job preparations, improvements implementation, run in hole and surface hookup. For each phase, challenges encountered, and lessons learned will be listed together with observed benefits. DIAL introduces a paradigm shift in design, installation and operation of gas lifted wells. This paper will briefly highlight the justifications of this digital technology in comparison with conventional gas lift techniques. It will consider value added from the design stage, through installation operations, to production optimization. This DIAL system installation confirms the ability to be implement the technology in a challenging dual string completion design to enable deeper injection while avoiding interventions on a well with a greater than 60-degree deviation. With remotely operated, non-pressure dependent multi-valve in-well gas lift units, the technology removes the challenges normally associated with gas-injected production operation in a dual completion well - gas robbing and multi-pointing. Despite the additional operational & planning complications due to COVID-19 restrictions, the well was completed with zero NPT and LTI. Once brought online, this DIAL-assisted production well will be remotely monitored and controlled ensuring continuous production optimization, part of PETRONAS' upstream digitization strategic vision. © Copyright 2021, Society of Petroleum Engineers
