Abstract
Fishing operations are complex and time-consuming. This is due to the associated uncertainty with the orientation and condition of the tool that requires fishing. Fishing usually is needed when least expected and brings a sudden halt to operations, especially if the downhole tools become stuck. Reaction planning begins at this time unless the project was planned properly from the outset. That reaction planning is not good is not the question. What is important is to establish the facts. What should be done to free the stuck? What will the cost be? This paper addresses these questions. It also emphasizes the importance of routine, continuous, but often unrewarded, effort by operation personnel.
An innovative approach to evaluate success ratio for retrieving a fish, not only using risk factors in the decision-making but also economical view is called PHR Fishing Complexity Calculator. Decision-making processes involved in recovering the fish when the downhole tools are stuck. The goal is to provide a usable wellbore at the lowest ultimate cost. Nowadays, the world is working in industrial revolution 4.0, where all are about digital transformation, increase the automation, artificial intelligence, and more simple work process. To keep the existences and explore the optimization in Industrial revolution 4.0, Oil and Gas Industry must be adapted and accelerated day to day operational in line with the advances of technology. Drilling & Well Intervention as an essential part of puzzles in Oil and Gas Industry which responsible not only to maintain the health of the wells but also make a guarantee the longevity of wells performance. The objective of this paper is to show the digitalization and simple workflow using PHR Fishing Complexity Calculator can maximize both quality and delivery time of fishing job "as simple as in your hand".
As a result, the success of fishing job can be increased from 39% to 71%. Approximately five wells can be converted into production and fish in holes can be retrieved. The success of those fishing jobs not only increases the satisfaction of fishing job but also increases production up to 153 Bopd and 2.9 mmscfd.
Moreover, the Drilling & Well Intervention Manager often is forced by an extended fishing operation to choose between the known costs incurred with abandonment of retrieval attempts and the unknown costs of continuing fishing operations. The successful manager makes the decision that costs the company the least money. Continuing fishing operations beyond some economic limit is a failure, even if the fish is retrieved and that portion of the hole saved, because more money has been spent in the fishing attempt than would have been spent by not fishing. The strategy is to minimize losses.
