Aerial surveillance for oil and gas operations can help in decision making process for a quick and appropriate response to deal with matters that potentially detrimental to the country. SKK Migas, in supervising and controlling the upstream oil and gas activities in Indonesia have made a good security system and mutually coordinated between operators and other institutions, but there are still several of that difficult to be covered and need to be improved by using technology effectively. Based on the issue reviewed it was recommended to utilize technology-based security systems to improve the security of the operator's working area and develop a security system with the support of drone technology in collecting pictures and videos oil and gas activities. Photos and videos obtained through the drone and then compiled to give an overview of monitoring activities, analysis, and geographic location conditions in the working area. Aerial surveillance activities by drones in the pipeline operation and maintenance area show the growth of residential areas along the pipeline right of way and the increase of population and industrial activities in the vicinity so that will affect to the increase of the potential risk of pipe explosion. By using drone technology to monitor the pipeline operation and maintenance area, it can help for a quick and appropriate response to prevent a greater risk and implement procedures to minimize impact on the environment. This paper outlines the utilization of drones to monitor the gas pipeline network in one of the oil and gas operation and concluded by recommending the use of drones to provide a snapshot of operational safety and prevent risks to the community.

Well abandonment is an obligatory work in the Production Sharing Contract. In the midst of low oil prices, this work cannot be postponed to do, especially for wells that have potential hazards. The longer it postponed, the greater risk will be face. It needs to be done with the most efficient way. Well abandonment of onshore-well in "R" Block of Central Sumatra Basin began in 2015. Reason for abandonment is varied from no more reservoir potential, mechanical problem, bad well integrity, missing part of wellhead, and vandalism. Since the initial start of the well abandonment work, the gold-plated effect appeared. The well abandoned in a very safe method, but not worth the risk. Discuss the procedures of selecting the well under potential circumstances to be plugged. An adjustment made by optimize it to fit-to-purpose abandonment according to Indonesia national standard while complying with the feasibility and safety operation. As a result, there is a decrease in average AFE cost during 2015 to 2017 by 29% which equal to US$8.5 million and still has decrease potential until the very fit-to-purpose method obtained. The average realization of AFE cost decrease from 48% to 34%. This paper shows that there is always a chance for optimization even though abandonment work does not have any gain of production and ignoring it also poses safety and cost risks. To date, this optimization has saved US$2 million.

Provide an overview of the procedures for abandoning onshore wells, backgrounds and technical requirements as a reference. Provide an overview of the utilization of reserved abandonment and site restoration funds to finance the abandonment of the wells. Plugging and abandoning the well is done when it has not more potential on productivity, has a well integrity problem, and is at risk of theft and the environment. Procedures undertaken to obtain approval for the closure of the well. The technical review of abandoning of the well refers to recognized national and international standards. Discuss some possible innovations to obtain more effective way in troubleshooting or to replace some procedures that are not possible to be followed. Reserved ASR funds disbursement procedures to pay for work. Challenges to speed up the process of disbursement of funds. Following standard procedures requires considerable attention and impacts on costs to be incurred. Disbursing ASR funds that have been reserved to pay for the work is not as easy as the established procedure. Several suggestions for improvements are made to speed work approval and disbursement of funds. Well abandonment procedures have been standardized, but submission procedures and ASR disbursement submissions are necessary for every operator to know. This paper provides an important guide for operators to submit P&A proposals and fund disbursements.

Review the Activity Based Costing (ABC) and Earned Value Management (EVM) fundamentals of being applied to the case study. Examine the constraints and its feasibilities in recommending the implementation of ABC combined with EVM to well abandonment projects. Well abandonment project is one of phase in the oil well's life span that must be done after it is no longer producing and to protect environment. Instead of giving revenue, well abandonment projects are spending money. To fulfill its deliverables with cost-effectively and in timely manner, the project coverage requires good planning, scheduling, and control. This paper is an actual case study which documents the abandonment of 7 oil wells located in Indonesia. ABC assigns resource costs to a cost object based on activities performed for the cost object. EVM coordinates the work scope, schedule, and cost goals of a program or contract, and objectively measures progress toward these goals. By applying the fundamentals of ABC and EVM, the abandonment project of 7 oil wells was completed in a total of 131 days, a slippage of 12% over the approved plan of 117 days and at a total cost of 1.078 million USD, versus the target cost of 1.074 million dollars. This paper explores the step-by-step process that is used to create the Baseline Schedule, track the progress against the schedule and report to the appropriate stakeholders. The paper concludes by recommending ABC combined with EVM be applied to other well abandonment projects.

Conduct comparative evaluations of offshore wells abandonment projects on either platform or underwater, whether rig or rigless. Identify challenges and effectiveness in terms of operations and costs. Discuss the preparations to be made before the work and the procedures to be done. Based on data of the offshore wells abandonment which were conducted between 2014-2017 in Indonesian waters, classification was made on subsea and platform, then differentiated the water depth and the total well depth, and are grouped to its method with the rig or rigless. Then look at the problems in the well. Money spent is also a point of comparison for evaluation. Plugging procedures refer to national and international standards that are recognized. Evaluating the work schedule of each group were assessed. There is a very clear distinction between the well abandonment on subsea and those on the platform. Also there are some differences between the use of the rig with rigless. This study illustrates how much it will cost to cover the well and also recommends work in the form of a project campaign to achieve its effectiveness. Plugging and abandoning the wells are commonly done on wells that are no longer expected to be productive. This comparative evaluation helps to illustrate how effectively doing the well abandonment works in the form of a project campaign.
