Abstract The development of Najmah-Sargelu (NJ-SR) limestone fractured reservoir, has a significant role in Kuwait Oil Company (KOC) 2040 strategy. To achieve this objective, hydrocarbon potential across the NJ-SR reservoir will have to be evaluated in the West Kuwait of Kra Al-Maru (Figure 1). First and foremost, this section will have to be drilled to planned section TD, cased off and successfully cemented. This paper discusses KOC experiences and best practices implemented to ensure utilizing managed pressure drilling equipment to achieve a successful 7-5/8-in liner cement job at well depth of 16,945ft. MD (15,756ft. TVD), and reservoir pressure and temperature ranges of 12,000 - 15,000psi and 230 - 280 deg F respectively. This new approach to cementing is based on Managed Pressure Drilling technology. It addresses running the 7-5/8- in liner and cementing it in MPD mode. A step-bystep procedure is provided that ensures a constant bottom pressure is maintained throughout the process. Risk assessment showing what can go wrong and mitigations are provided, and the method is described in detail to allow readers comprehend the unique case presented in this paper. Managed Pressure Cementing (MPC) technique in case study well is compared to offset wells in West Kuwait Field where cementing was conducted conventionally. In most cases, the cement bond logs show cement dispersed throughout the annulus with no continuous bond - channels in the cement behind the casing. The most significant new findings from this paper are that, in a couple of wells where there were no losses while pumping cement conventionally- the cement bond logs showed moderate to poor cement behind casing and channels within the cement. Figure 1: Kra Al-Maru Field, West Kuwait This technology offers opportunity to achieve good cement bonding with liner in fractured limestone which can be problematic due to the risk of losses and the presence of hydrocarbons with high pore pressure in West Kuwait NJ-SR intervals. This novelty approach using Managed Pressure Cementing technique to case and cement liners in West Kuwait fields and tight margin reservoir will ensure good cement bond logs behind casing and improve well testing and completions strategies.

Al-Haddad, Saud (South & East Kuwait, Kuwait Oil Company, Ahmadi, Kuwait) | Watyan, Abdullah Al (South & East Kuwait, Kuwait Oil Company, Ahmadi, Kuwait) | Mahabirsingh, Nalini (bp) | Al-Ragheeb, Sara (South & East Kuwait, Kuwait Oil Company, Ahmadi, Kuwait) | Al-Ajmi, Salem (South & East Kuwait, Kuwait Oil Company, Ahmadi, Kuwait) | Khaleefoh, Ahmed (South & East Kuwait, Kuwait Oil Company, Ahmadi, Kuwait) | Al-Jadi, Menayer (South & East Kuwait, Kuwait Oil Company, Ahmadi, Kuwait) | Bentoumi, Sofiene (bp) | Duong, Lea (bp) | Novruzov, Kamran (bp) | Amr, Mohamed (bp) | Fataliyev, Vusal (bp)
Abstract Greater than 65% of South & East Kuwait, oil production is from more than 1000 Artificial Lifted (AL) wells, mainly Electric Submersible pumps (ESPs). This is managed in three different Areas through a total of fifteen different facilities, with downhole Artificial Lift equipment from greater than five (5) different vendors and numerous subcontracts for the top side equipment to match the downhole requirement. S&EK is also on an active transition to 100% Artificial Lift. The magnitude of production, the large number of wells, variation in equipment, relatively widespread facility and company future plans can give a sense of the operations, engagement and networking required to streamline various aspects to deliver strategic business value systematically and repetitively. The journey, processes and results of Artificial Lift technical excellence embedded in the organization will be shared in this paper. The importance of continuous integration, alignment across different directorates and affiliated key performance indicators (KPIs) across the business to realize win-win outcomes will also be illustrated. S&EK technical expertise and bp have been embedding best in class processes, equipment and further developing in house expertise to enhance the Artificial Lift portfolio. The strategy adopted was to maximize production within the reservoir management strategy while collaboratively realizing additional value for other directorates involved in the process. Consequently, this resulted in win-win scenarios for S&EK, overall KOC and vendors. To be able to achieve this, some of the various aspects which the S&EK Field Development and bp partnership executed were: developed specifically tailored in house data analytics systems, hosted integrated workshops with Artificial Lift vendors and KOC cross functional teams, streamlined ESP systems, networked across directorates to increase well and reservoir surveillance, enhanced well and system modeling to influence ESP designs, took several key steps to preserve well integrity and steps to reduce oil losses (both from natural flow and artificially lifted wells). As a result of the integrated interventions taken, some of the results realized by S&EK, KOC were: Streamlining of ESP systems to a set of wide range ESPs with each ESP vendor Significant, systematic increase in incremental oil from artificial lift optimizations Enhanced ESP designs Systematic increase in the percentage of ESPs operating in the recommended operating range Enhanced ESP run life Preservation of well integrity and Enhanced Artificial Lift expertise and integrated skill set to safely maximize production and enhance efficiency to effectively manage the current and rapidly increasing Artificial Lift portfolio and Integration of the above to reduce oil losses in the asset. Overall, as a result of the actions taken, in 20/21, 21/22 and 22/23, additional value of at least 14.1 million KWD (USD 46 million), 25.4 million KWD (USD 82.9 million) and 35 million KWD (114.3USD million) respectively was generated. This additional value could have gone unrealized without the appropriate interventions.

Kuwait Oil Company's (KOC) first offshore exploratory and drilling operations for oil and gas are expected to end in 2026, the state-owned firm's chief geologist said according to news reports. But the timeline "depends on the progress of operations at sea," KOC's Ahmed Al-Otaibi told reporters during a briefing at the Kuwaiti oil ministry. Kuwait began exploring offshore as it invests to meet future oil demand and received its first offshore rig in mid-2022, KOC parent company Kuwait Petroleum Corporation Chief Executive Sheikh Nawaf Saud AlโSabah, Reuters reported in June 2022. The operations began last year and are expected to take 4 years, AlโOtaibi said. The firm will drill six offshore wells in the exploratory area of about 6000 km2.

A Success Story of Detecting the Source of Gas Leak in Annulus-B Using Total Well Integrity Tools and the Remedial Action in an Oil Well of Kuwait Oil Company
Matar, Saad (Kuwait Oil Company) | Jalan, Shiv (Kuwait Oil Company) | Ali, Yousef (Kuwait Oil Company) | Alshammari, Ahmad (Kuwait Oil Company) | Al-Ajmi, Eiman (Kuwait Oil Company) | Aparicio, Ciro (BP - British Petroleum) | Gobran, Mahmoud (Senergy Oilfield Solutions) | Saleh, Arafat (Senergy Oilfield Solutions) | Prosvirkin, Sergey (TGT Diagnostics) | Vishnu, Raveen (TGT Diagnostics)
Abstract Objectives/Scope Well integrity monitoring is one of the critical processes in oil and gas wells to prevent unintended fluid movement or loss of containment to the environment. In this case study, there was continuous gas leakage to surface at high pressure through annulus "B" of an oil well in East Kuwait area. The detection and securing of the gas leak in this well was essential not only for securing the well and restoring production, but also for environmental considerations due to the sensitive geographical location. This paper presents an innovative logging combination for total well integrity assessment, including spectral noise, high-resolution temperature, multi-barrier corrosion evaluation, and fluid type identification for downhole gas leak detection. The paper also presents remedial actions taken to secure well integrity after assessing and evaluating diagnostic logs at each stage with a workover rig. Methods, Procedures, Process Innovative combination of different measurements for total well integrity assessment including spectral noise, high-resolution temperature, multi-barrier corrosion evaluation, and fluid type identification logs have been used to detect the downhole source(s) of this gas leak. Multiple cement squeezing across single and multiple casings were designed and performed based on the logging results to stop the leak and secure the well. After completing each cement squeezing job, surface pressure in annulus "B" was being monitored and downhole logging surveys were being performed to check if there was still downhole gas flow. Results, Observations, Conclusions The different logging results showed strong indications for multiple sources of this gas flow in annulus "B" across different formations around the well. The poor primary cementing job allowed formation fluids (e.g. gas, oil and water) to migrate to shallow reservoirs and surface. The remedial cement squeezing jobs have been successfully performed and achieved a solid hydraulic vertical barrier to stop the gas flow activity. The gas flow stopped, surface pressure in annulus "B" disappeared and restored production of 700 bopd from the well. It is a case story of a successful well integrity workover in a very challenging well that ended by fixing the gas leak, restoring the well production, protecting the surrounding wells and environment, and saving the cost of either sidetracking the well or P&A (plug and abandonment). Novel/Additive Information The innovative well integrity logs in combination with conventional cementing remedial jobs, allowed us to achieve complete well integrity. The use of advanced well integrity logs (e.g. spectral noise, high-resolution temperature, multi-barrier corrosion evaluation, and fluid type identification) were beneficial to determine the exact depths of the leak points and determine the exact location of the remedial jobs (e.g. remedial cement jobs) to stop the migration of gas from the formation to shallow reservoirs and surface.

Abstract The Ministry of Oil (MOO) is going with new task to realize the New Kuwait Vision, and so, MOO is on track to shift to a complete digital work environment. Preliminary steps toward the transformation arose with a high concern of connecting with one of the main stakeholders, the Kuwait Oil Company. All in optimism to modernize the data digitally between the Kuwait Oil Company and the Ministry of Oil when it comes to the Technical papers proposal. Based on such, many more motives appeared to modify the work process from manual to digital. Therefore, crucial plans were established based on calculated plans set by managerial personnel to group delegated tasks. As an outcome, the staff with recognizable capabilities dispersed these tasks and executed most using current applications. In the ancient systems, papers that used to take around 21 working days to be reviewed from start to finish, now in a days with the digital system, take around 3 days only, saving a lot of time and resources for each technical paper that is submitted through this new and improved system. Of course, guaranteeing a paperless route brought about many challenges and worries. The most important of them being the reassurance of security measures to protect personnel and the data sharing process. Additionally, the reception of senior workforces to change habits and relearn new procedures of producing daily tasks, as well as, increasing the capability through training courses and supervision. Furthermore, tackling errors exposed within the system through trial and error to boost the experience and optimize workflow.

Al-Obaidi, Abdulmohsen (Kuwait Oil Company) | Al-Ibrahim, Abdullah (Kuwait Oil Company) | Al-Dhafiri, Abdulrahman (Kuwait Oil Company) | Al-Mehanna, Hamad (Kuwait Oil Company) | Al-Haddad, Mohammed (Kuwait Oil Company) | Al-Harbi, Sultan (Kuwait Oil Company) | Ayyad, Hazim (Schlumberger) | Mehraj, Majid (Schlumberger) | Abdulrahim, Khaled (Schlumberger) | Hernandez, Guillermo (Schlumberger)
Abstract Digital Slickline (DSL) Technology for production logging has been successfully implemented in South East Kuwait (SEK) oil fields. This advanced technology enabled Kuwait Oil Company (KOC) to save significant amount of deferred production and operational cost without compromising on the data quality. In addition, it reshaped how the operator performed surveillance operations through a more efficient workflow. A detailed analysis was carried out in more than 11 wells where production logging was acquired with DSL. Comparing the new workflow to the traditional workflow showed that DSL implementation saved around 51,000 barrels of deferred oil production and improved operational efficiency by 72% compared to the conventional workflow, without compromising on data quality during both real time and interpretation stages. Based on these results, KOC decided to implement this workflow in majority of the wells and now it has become the standard for production profiling in ESP wells.
