Gas lift systems optimization is a dynamic process throughout well production life in order to maximize the overall field production. Traditional gas lift valve installation standards were replaced by a new strategy, at which valves were converted to smaller port sizes, dummy and Venturi ones.\u0000 A mature offshore field, with more than 460 gas lifted wells and limited gas availability, undergoes depletion phase. Most of the gas lift design bases were initiated during the production start-up and has standardization set of large gas lift valve port sizes with narrow spacing. Inconstancy of the well flow condition during reservoir depletion added complications to the system and made its operability incompatible with the initial design. Therefore, a screen-out model was created to select candidate wells for downsizing and for dummy and Venturi valves changing-out. After screening, 70 wells were selected for applying the new strategy.\u0000 A successful optimization in gas lift system was carried out after selecting 70 candidate wells. The gas lift valve change-out (GLVCO) operation included changing valves from normal unloading valves to dummy ones, downsizing to smaller port sizes, changing valves from edge-orifice operating to Venturi valves and applying new gas lift design approach in order to increase closing pressures of shallower valves by considering ambient the temperature effect. Improvement in wells performances was evaluated using real-time monitoring system, multi-phase flow meters and portable well testing package. Applying the new strategy resulted in exceptional improvements in 47 wells by injecting gas from deeper valves, decreasing the downstream pressure to prevent re-opening of shallower valves, optimizing gas lift injection rate and enhancing gas lift system stability. Accordingly, more than 7000 BOPD were added to the production stream and led to saving more than 10 MMSCFPD of injection gas to be used for other wells and mitigating flow assurance difficulties regarding scale precipitation due to excessive cooling.\u0000 This paper reveals the effectiveness of smaller port sizes, dummy and Venturi valves in enhancing the gas lift performance and maximizing the recovery. It provides an improvement philosophy for managing the gas lift wells from the design concept to field application.","PeriodicalId":286390,"journal":{"name":"Day 1 Mon, March 13, 2023","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126097446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interestingly enough there have been many operators in the field with distinct performances yet by deploying the same vendors and service providers held in common. By considering that it is statistically proven that the larger the project budget, there are higher chances for failure, effective tailoring of methodologies in large scale mega-projects would be crucial and decisive. In many cases failures are a consequence of simply applying methodologies already experienced in small scale projects on complex and sophisticated projects with a variety of influential factors and a huge network of stakeholders. The study has provided an insight on how effective approaches in project management or conversely mismanagement could play as the main rout cause in a chain of events corresponding to either saved time or Non-Productive Times in well construction operations by presenting real cases elaborated in detail.\u0000 Cases show how failure in collecting requirements and recognizing the interdependencies among each necessity in the early stages of the project and subsequently overlooking the related cost, time and risks could cause massive cumulative financial loss. Additionally, failure to recognize wise investments in vendors and service providers as the 1-10-100 rule which explains how failure to take notice of one initial investment escalates the financial loss exponentially would have staggering consequences. The current paper explains how being proactive in an extensive planning phase could ease the execution stage as a great investment in time spent. From a human resource perspective, it has been demonstrated that how the ability and skills of the project team e.g. effective communication in complex networks with multiple reporting relationships and data-driven decisions by statistics could prevent cognitive biases and errors in decision making. Furthermore, powerful alignments come from shared and common motivations and morale for all engaged parties and the supply chain being service providers, rig contractors or the field operator and there should be an answer to the question, what's in it for me when asked by each of these parties.\u0000 Overall the study presents real cases and lessons learned showing how the main rout causes of Non-Productive Times could go back deeply to ineffective project approaches from a project management perspective in a system dynamic chain of events rather than to just address the emerged symptoms of failure in drilling operation.","PeriodicalId":286390,"journal":{"name":"Day 1 Mon, March 13, 2023","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123561007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An organization’s leadership is responsible to identify the best approach that helps the safety management system to achieve its expectations and adjust it once needed. The effective implementation of The Safety Management System is crucial for business continuity, especially in a high-risk industry such as oil and gas fields.\u0000 Ras Tanura Producing Department had shown a high level of collaboration and engagement with Loss Prevention Department that led to improve the safety performance and culture among Ras Tanura Producing Department employees. As a result, Ras Tanura Producing Department has achieved an overall score of seventy six (76) percentage during the assessment of safety Compliance Review management system carried by Los Prevention Department in the year of 2021, which demonstrates a commendable improvement from the year of 2018 review score of fifty seven (57) percentage which is recognized as the highest in Saudi Aramco Company.\u0000 Ras Tanura Producing Department safety program effectiveness was assessed utilizing a risk based approach which focuses on the most prevalent areas for improvement identified in an analysis of Saudi Aramco safety performance and a thorough review of Ras Tanura Producing Department’s documentation. The review also assessed the implementation of the Eight Lifesaving Rules. Evidently, Ras Tanura Producing Department has an opulent and mature Safety Management System that reveals comprehensive and logically written processes.

The positive and encouraging results achieved using this tool will also be discussed.\u0000 Electromagnetic pulse surveys were conducted in 2016 and 2020 to evaluate independently the metal loss in three casing barriers. The 2016 analysis involved a simplistic data processing method. A more sophisticated processing technique was recently applied to both surveys (2016 and 2020). This new method estimates the thickness for each barrier through forward modelling based on the numerical solution of the Maxwell equations. A newly introduced electromagnetic tool was also run in combination. This is a unique approach because it provides a segmented electromagnetic metal thickness evaluation of the first barrier without the need for pad contacts with the casing wall.\u0000 The simplistic processing from 2016 assumed, for each barrier, a baseline for the tool readings that corresponded to the nominal casing thickness. It then translated the deflections from this baseline into a metal loss or gain. These figures were output only when they exceeded the tool's accuracy. The advanced processing that was used in 2020, which is based on forward modelling, estimated less metal loss in general in comparison with the 2016 survey. These results agreed with the segmented tool estimations for the first barrier, which was run in combination in 2020. This confirms the methodology's robustness and accuracy. In addition, this new method outputs metal loss figures at every depth point regardless of the tool accuracy. The new processing was applied to previously acquired data sets in two additional wells in the same field, and the obtained results were very satisfactory.\u0000 The new tool, which provides a segmented electromagnetic metal thickness evaluation, also delivered exciting results by providing accurate thickness estimations in eight circumferential sectors of the casing wall without pad contact. This constitutes a substantial improvement over the existing all-round and averaged measurement offered by conventional electromagnetic tools. These segmented results enabled the client to make a better-informed decision about the well and to postpone an expensive workover.\u0000 This paper confirms the necessity of time-lapse surveys for monitoring the integrity of downhole tubulars. It also proves that numerical solution of the Maxwell equations through forward modelling of acquired electromagnetic data yields robust and more accurate thickness estimations than the previously used methods.

Workover operations in such harsh environments involve several operational risks and high related costs. Electrical Coiled Tubing (E-CT) equipped with tubing encapsulated mono-conductor cable was used to gather accurate intervention data with real-time logging capabilities. The system used didn't require the temporary installation of a test ESP completion string after pulling the failed ESP pump, saving cost, overall intervention time, optimizing zonal isolation for the water producing intervals, and increasing well recovery in these oil wells.\u0000 This case study presents a challenging workover for a mature field where E-CT was used to convey a combination of Pulsed Neutron Logging (PNLT) and Production Logging Tools (PLT) while pumping Nitrogen (N2) to lift the well. This enabled maximizing the reservoir production potential while monitoring the dynamic drawdown being applied to overcome the masking potential for the PNLT due to killing operations during workover. Real-time readings from the PNLT, PLT continuous spinners, gamma-ray, pressure, and temperature sensors accurately identified the well's water contributing intervals and flow profile. This accurate interpretation of the water saturation profile across the reservoir was then used for optimum reservoir management and selective zonal isolation. Dynamic wellbore modeling software was used to design the lifting and logging operations for optimal operational efficiency and to increase oil production and reduce water production.\u0000 Deployment of E-CT in such a harsh environment was challenging in terms of operational execution to ensure safe conveyance of the real-time logging tools while performing the conventional lifting of the well. Intervention time was optimized through two runs to evaluate the formation performance and water saturation profile before isolating the water-producing intervals.\u0000 Such utilization of E-CT allowed accurate formation evaluation, water saturation profiling, and nitrogen lifting of the well resulting in an optimal intervention. Results showed a 50% reduction in water production and an increasing well potential from the upper intervals. Total workover and intervention costs were reduced dramatically compared to other treatment options for water production problems with potential workover complications and deferred production.","PeriodicalId":286390,"journal":{"name":"Day 1 Mon, March 13, 2023","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134489910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
