Successful Customized Thru-Tubing Plug & Abandonment from a Light Well Intervention Vessel as an Alternative to Heavy Workover Operations to Reduce Time and Cost - A Case Study from Brazil
Authors: Boldrin Rodrigo , Martinez Raul , Nunes Mauro , Ayusso André , Vivas Victor 
Published: October 2023

Abstract
Since Brazil produced first oil from the Campos Basin (offshore) in 1977, several companies have tried to reduce costs and speed up their offshore interventions. This requirement is even more necessary as the fields mature with limited oil production.
The operator's objective has always been to avoid interventions or increase the time between them for the duration of the wells’ life. When required, the normal way to perform these interventions has been by using heavy workover rigs, but during the last five years, this process has changed since Brazil started to perform these activities using Light Well Intervention Vessels (LWIV). These vessels allow a different approach to traditional methods of thru-tubing interventions while still meeting the requirements of local regulations.
This paper describes recent thru-tubing techniques used in a mature field during a large P&A campaign. It shows the high potential synergy integrating a LWIV with Coiled Tubing (CT), Slickline (SL), Wireline (WL), and cementing technologies for use in Brazilian activities.
CT equipment rigged up as the primary and selective intervention on a LWIV offers more flexibility between service lines, reducing time with safety and quality. This integrated solution applies since the most recent Electric (e-CT) technologies added to conventional tools, such as inflatable packers, slickline plugs, tubing punches, logging devices, and others, creates new procedures and capabilities to speed up the well intervention operation. Some jobs previously performed in over 45 days, can now be carried out in less than 13 days.
Comparing this new offshore P&A thru-tubing technique with traditional heavy well workover interventions results in a significant reduction in Abandonment Expenditure (ABEX) when operations are performed through the production tubing, allowing the completion tubing to be left in the well.
The method described in this paper, backed up with a detailed case study, illustrates the significant parts of the process, from cement placement preparation and slurry specifications to pumping through the CT into the wellbore and the cost reduction gained. Conclusions and recommendations offer more technical references for further similar applications.

Abstract
A high-pressure gas exploration well was drilled in May 2018. The main objective of the well was to explore for gas in three different formations. The well underwent a successful fracturing intervention which increased the total gas production, however, at a later stage, a leak point was observed at the tie-back seal followed by repetitive isolation plug failures. The criticality of the well status was due to the integrity failure while having above 9,000 psi of tubing head pressure. The objective of the paper is to describe the successful method of restoring well integrity in a high pressure well by retrieving the failed isolation barriers.
Prior to the intervention and due to the failed integrity of the high pressure well, a work cycle was developed to ensure the successful intervention was executed in a controlled manner. Due to the complexity of the restoration process, contingencies were aligned as part of the retrieval and isolation intervention.
Restoring the well took place in a sequence initiated firstly by the retrieval of a failed junk catcher and the top retrievable plug using the coiled tubing. This was followed by pushing the bottom failed retrievable plug to TD successfully without collapsing the Coiled Tubing string, at the live conditions of the well. The final restoration step included the utilization of a mechanical plug to be set followed by 300 m of cement, to ensure well isolation for next workover stage.
The most pivotal challenge was the intervention in a high pressure well of above 9,000 psi in the presence of a failed integrity issue. The strategy of well restoration was a complex combined intervention of utilizing multiple downhole tools to retrieve the well barrier, clean the unexpected debris accumulated and successfully control the leak that has resulted in the integrity failure of the well. Although controlling the failed retrievable plugs was difficult, due to the high pressure pushing the unset plugs shallower, manipulating the status of the well between opening the returns and shutting-in during the intervention was observed a secondary control parameter throughout the job.
The combined approach of Coiled Tubing's tubing force analysis, downhole tool configuration, well condition and contingency management throughout the intervention resulted in the successful restoration of a high-pressure gas well.
The paper presented highlights the successful restoration of a complex intervention executed through Coiled Tubing. This case helps to present the value, challenges, lessons learnt and opportunities existing in well restoration that would have previously been deployed through a costlier mean of workover operation.

Abstract
This paper introduces a groundbreaking development in well completion technology - the Dual Packer Cut-to-Release (CTR) system. This innovative solution offers a superior replacement for the conventional pull-to-release dual packer, CUT-TO-RELEASE (CTR) technology. The key feature of the Dual Packer CTR lies in the integration of a defined cut window within the challenging geometry of a 9-5/8" × 3-1/2" × 3-1/2" production packer design. This integration provides unparalleled risk mitigation, ensuring optimal well integrity throughout the high-profile well completion process and its entire operating life.
With recent advancements in the reliability of well intervention tools, the confidence level among operators in production and injection applications has significantly increased. The Dual Packer CTR technology leverages these improvements to offer a higher level of reliability and precision during the releasing (cut) process. Additionally, this technology enables precise zonal isolation, enhancing well performance and providing versatility for deployment in supported and unsupported wellbores.
The paper discusses the development process, including the selection of field-proven technology and the rigorous testing and validation procedures carried out to ensure the packer's robustness and functionality. The successful implementation of the Dual Packer CTR in field installation further solidifies its position as a dependable and efficient solution for challenging well completion operations. Ultimately, this advanced technology provides operators with enhanced confidence and assurance for achieving successful production and injection applications.

ABSTRACT
Drilling across Shuaiba formation in the western wells of Kuwait poses significant difficulties, including severe loss of drilling fluid, unstable shale formations, and deteriorating hole conditions, which may require sidetracking. Cavernous porosity development in Shuaiba formation leads to potential severe lost circulation during drilling through it. This project aims to develop an engineered solution to efficiently drill through these challenges and to minimize nonproductive time, ultimately reducing the overall cost of the well.
The proposed solution involves utilizing a casing-while-drilling technology that features a drillable bit, engineered to conform to the field's formations. It aims to drill through fractured dolomitic limestone and sandstone formations while simultaneously setting the casing.
This paper will discuss the geological aspect of Shuaiba formation at the early Cretaceous that lead of the major mud losses, and the proposed engineering solution with casing while drilling for minimizing the non-productive time when drilling into Shuaiba formation. The selection process of using casing while drilling or conventional casing was also discussed because the completion requirement at the lower part of the reservoir section.

Summary
This paper is to share the practical implementation of the Data Strategy for the Energy Transition in the Middle Eastern based International Energy Company. While the energy transition is driving change in our industry, with gas acting as a key bridging fuel to a lower carbon and sustainable future, the data management practice has seen little shift in that direction. Many energy companies are refocusing their efforts to expand across the value chain while also embracing new energy sectors that help deliver a sustainable future. With data volumes growing exponentially and the data stack continuing to undergo rapid innovation, companies are struggling to keep pace to drive business agility while keeping the associated costs and complexity in a healthy ratio against the value created from digitalization.
Hence, a practical implementation to the modern data strategy for building tech intensity is needed. A framework was defined together with Microsoft and executed together with the Middle Eastern based International Energy Company. The 5 steps approach to practically implement these are as follows: Assessing current data management practicesDefining strategic objectives and goalsDeveloping a roadmap for implementationAllocating resources and budgetExecution, monitoring, and evaluation
Based on the practical implementation of the Data Strategy for the Energy Transition and major lessons for designing a new enterprise data architecture, few themes have been identified and discussed in the paper.

Published: October 2023

Abstract
The objectives of the project is to develop a blended training program for Stuck Pipe Avoidance using e-Learning, video learning and Virtual Reality, VR, to increase participants attention throughout the course and to enhance knowledge retention.
PDO works in a complex, high-risk, high-consequence work environment where accidents can be extremely serious, causing damage to people, assets, and the environment. The traditional multiple day course content was reviewed and updated to incorporate VR technology into a blended training program for Stuck Pipe Avoidance with e-learning, 3D models, animation, and video learning modules so that the company could train their people in the safest way possible whilst providing a high level of realism and knowledge retention and allowing the trainees to learn more effectively and efficiently.
Use-case studies and historical experience were incorporated into development of the new content.
The vendor used the stage gate approach to get the SME's approval before developing the content into digital formats.
A blended approach resulted in increased participants attention and gamified VR training modules helped participants to massively increase their knowledge retention by creating highly immersive virtual learning environments which helped them to focus all of their attention on their training. This creative approach helped the company to deliver training experiences that were truly immersive and engaging without the usual constraints, limitations and costs imposed by the physical world, allowing candidates to fail in a safe environment.
Pre and post training questionnaires confirmed Class participation increased, employee motivation increased, and knowledge retention increased, throughout the new blended course compared to the traditional approach.
VR is being increasingly used in education and training institutions around the world but has been slow to be adopted by the Oil & Gas industry. This project clearly demonstrates the benefits to include VR technology into a blended approach, being better prepared to mitigate risks in high risk, high consequences environments.

Published: October 2023

Abstract
The objective of this environmental initiative is to utilize dredged sand material for the development of artificial islands near Abu Ali Island, Eastern Province, Saudi Arabia. The aim is to reduce the environmental impact of the dredging process and create a sustainable solution for the disposal of the dredged materials. The project demonstrates a modern, sustainable and circular economy approach to target the biodiversity threats in multi-dimensional aspects and transform these threats into opportunities to improve Abu Ali Island's ecosystem.
The analytical approach consists of following methodology:
Identify the total quantity of sand waste generation during the dredging operation. Evaluate and identify potential waste storage facility as the laydown area on the island to temporarily store the waste. Calculate number of trucks required to transport the waste out of the area. Conduct site verification to identify potential waste disposal areas or find an alternative solution to utilize the waste material. Coordinate with corporate entities and project groups to obtain approval for proposed waste reuse solution.
The reuse of dredged sand material for the development of artificial islands has several positive environmental impacts. First, it helps reduce the amount of dredged material (1.5MM m3) that needs to be disposed of in offshore locations or on landfills, which can cause harm to marine life and ecosystems. Second, it creates a new habitat for marine organisms and promotes biodiversity. In addition, it will eliminate the transportation cost (150,000 trucks) and associated traffic hazards if the material is transported outside the island. Finally, it promotes sustainable development by reducing the environmental impact of human activities on the natural environment.
The implementation of this unique innovative approach at Abu Ali Island Corporate Biodiversity Area demonstrates a lead-by-example role in the environmental aspects. The corporate commitment as a global oil and gas producer toward the environment was clearly illustrated in this initiative. Building a circular environmental culture that contributes to combat climate change, sustainably falls under the company's corporate strategies. The development of artificial islands is not a new concept, but the use of dredged sand material is a sustainable and circular solution. The approach can also be proposed for the redevelopment of urban waterfront areas, where dredging is a common practice to maintain shipping channels. This environmental initiative is a win-win solution that can benefit both the environment and human development.

Published: October 2023

Abstract
Risk assessment is the key and most crucial phase in risk management during different well's life cycle. It is a rigorous procedure for identifying, evaluating, and quantifying risks that have the potential to endanger people, have an adverse effect on the environment, or damage assets. With the use of a scenario-based qualitative risk assessment technique and the corporate 6X6 risk matrix, ADNOC Offshore built a new tool for automated well risk assessment that enable the company to identify the failures, control and mitigate well integrity risks due to different failure scenarios.
In the digitized risk assessment module, all hazard scenarios have been identified to cover all possible leak paths and conductor pipe structural risks. A detailed barrier analysis is then simulated to define the probability of failure for each scenario. In addition, all operating limits are retrieved from the database along with various consequences factors such as people, safety, assets, company reputation and business. Finally, well risk is ranked by evaluating over 4,000 simulated risk scenarios using the ADNOC 6X6 matrix. All functions were added to in-house software and linked to all relevant well data such as X-tree, DHSV, annulus pressure survey, Maximum Allowable Anticipated Surface Pressure (MAASP), conductor pipe… etc.
The digitized risk assessment ensures compliance with local, international standards and best practices by effectively risk assessing and ranking different types of wells (oil and gas producers, water and gas injectors…etc.), flowing or injecting sour and sweet fluids at different locations (island or wellhead towers) with single or multiple completion strings equipped with Surface or subsurface control subsurface safety, constructed with up to four annuli in addition to structure assessment for the conductor pipe.
Once the failure scenarios have been ranked and the final risk ranking has been determined, a Well Integrity Passport (WIP) will be created. This WIP will encompass all the information regarding the well, including risk assessment, short-term and long-term action plans, as well as mitigation plans, the assigned party and due date for each failure scenario will also be included. Subsequently, the Well Integrity Passport (WIP) will be automatically circulated for approval based on the approval hierarchy.

Abstract
The project for the replacement of the temporarily repaired and corroded 24" high pressure flare line was delayed for various reasons. During this period the temporary composite repairs carried out expired and integrity could not endorse the line. There was an immediate requirement for a low-cost fast-track solution to tackle the integrity threats of these expired long composite wrapped repair sections on this very critical line. The conventional way of repairing is like for like which would require a shutdown of the line. However, the line cannot be shut down as most if not all the plant relief in Island is connected to it. It will have major impact to the production to the tune of 95million USD. Company Senior management requested a quick temporary solution till the permanent solution is awarded and completed by 1Q-2026. A-loc solution was developed in-house to avoid shutdown of critical system where the local vendors were unable to provide effective solutions. The above fast track works were executed safely during the pandemic. This paper presents the best optimized repair and execution methodology for the critical pipework avoiding total shutdown of essential system. Also, this paper highlights how in-house Company Technical Support can contribute towards More Profitable Upstream by providing a code compliant temporary repair and cost-effective solution for the Company’s business continuity.
