The drop in oil and gas demand, coupled with travel restrictions due to the COVID-19 pandemic caused a drop in global oil market prices. This has resulted in a drop in the output in the global economy. These drop-in output means that there were losses associated with the COVID-19 pandemic. The aim of this study is to evaluate and investigate the economic effect of the coronavirus pandemic on the oil and gas industry in Ghana. The evaluation was done using economic performance indicators such as GDP and Crude oil prices. In addition to this, a loss function-based algorithm was used to model the projected economic loss during this period. To demonstrate the model, data was collected from a study site and used in the model. The study is useful for decision making on the preparedness for future pandemics, especially in oil dependent countries.","PeriodicalId":220441,"journal":{"name":"Day 3 Wed, August 03, 2022","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123758734","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}

Suites of four geophysical well logs data obtained from the field were used. The study determined properties of the reservoir such as lithology, shale volume (Vsh) porosity (Φ), permeability (K), water saturation (Sw), net pay thickness, among others from well logs. Detailed petrophysical analysis revealed five reservoirs. Average reservoir parameters such as porosity (26.1%), volume of shale (4.6%), water saturation (26.52%), permeability (7138 md) and net gross (0.893) were derived from the petrophysical analysis of the delineated reservoirs. Each parameter was upscaled and the Properties including porosity, water saturation, permeability models have been generated and were distributed stochastically within the constructed 3D grid using Sequential Gaussian Random Simulation Function algorithms present in the software. Based on the interpretation and petrophysical analysis of the K field, it is recommended that Cased-Hole Density logs should be acquired in those wells without density logs to accurately estimate total porosity, Special consideration must be given to the acquisition of representative and useable Routine and Special Core Analysis (SCAL) data when drilling new wells in order to reduce uncertainties and validate the result of the wireline logging.","PeriodicalId":220441,"journal":{"name":"Day 3 Wed, August 03, 2022","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129477060","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}

Over the past two decades, scientists worked to find alternate sources of energy that were not fossil-based. Success in this endeavour led to what is now termed as a global transition to renewable and sustainable energy. In most climes, this marks a new beginning filled with opportunities and a chance to allow the earth to heal. Highly developed economies like Norway and some member countries of the European Union, being the driver of the transition, have begun to make policies that align with the new age, setting themselves to have a stake in the profit. The African continent, which has abundant energy resources but is neither a major contributor nor a driver of climate change but suffers just as much as other continents in the world from its effects, is not in a position to take any corrective action, showing the incapacity to participate in any potential economic gain. This paper studies the Sub-Saharan landscape by visiting the histories of the nations in question based on the energy resources within their borders and the current state of energy transition development. It examines the freedom of said countries to create policies that work for them, indicating the implications of lack of planning and the taint it may have on the new trend in the countries of interest. Efforts would also be made in highlighting a roadmap that can serve as a knowledge base to facilitate the implementation of best strategies in enabling successful energy transition in Sub-Saharan Africa.","PeriodicalId":220441,"journal":{"name":"Day 3 Wed, August 03, 2022","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114215917","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}

This method overcomes the potential risk of high backpressure imposed on the production tubing by manual choking or other control solutions using wellhead valve. Firstly, a model of Oredo well O7 is constructed with a closed node constituting the reservoir unit and a surface pressure node on the wellhead. An automated pressure integral derivative controller that senses and controls the bottomhole flowing pressure by actuating the wellhead choke is then installed at the wellhead. Measurement input to the auto-controller is delivered via an insitu transmitter. This design approach is successfully applied to the well O7 model through a commercial multiphase simulator on well models and provides a condensate banking monitoring mechanisms with improved production output.","PeriodicalId":220441,"journal":{"name":"Day 3 Wed, August 03, 2022","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130452056","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}

However, the cost of these STC equipment may be prohibitive for wells drilled in shelf or swamp environments. The delivery of STC relies on different communication methods to communicate with and function the down-hole tools that make up part of the STC assemblies such as the \"hydraulically actuated sand screens\", the \"radio frequency identification (RFID) actuated sleeves\", and \"valves\". These different communication methods permit the running of a closed-loop system to ensure well integrity through-out the deployment and commissioning of the completion system. This paper will discuss pre-job planning, field execution and lessons learned from technologies developed to fit this environment while simultaneously challenging conventional thinking around open hole and cased hole completions systems, while addressing the operator's key drive towards capital efficiency through reduction of rig-days by as much as 50%. While several of the components incorporated in the STC system had been run previously in isolation, this paper will discuss the steps taken to facilitate the first full system approach to the application of sand screens fitted with hydro-mechanical inflow control device sleeves designed to actuate on pressure bleed-off, RFID enabled tools in the first hybrid single trip interventionless sand control completion system, and the time savings realized while ensuring well integrity through-out the deployment. Several components within the completion system have been equipped with novel enabling technology, RFID operated reservoir isolation valve at toe of the completion, wire wrapped sand screens fitted with hydro-mechanical sleeves designed to actuate on pressure bleed down complete with inflow control devices, and fuse actuated remote operated circulating sleeves for annular fluid displacement, which will all be discussed within.","PeriodicalId":220441,"journal":{"name":"Day 3 Wed, August 03, 2022","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127563262","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}

This information is used to identify the various systems where overpressure occurs, as well as evaluate the contingencies put in place to control it. Cases where the controls are inadequate and the implications on process continuity are also assessed.\u0000 To solve the challenge created by overpressures in a process facility, an evaluation of the root cause and a clear definition of the conditions under which they occur were done. Certain thermodynamic principles, in combination with process conditions, fluid characteristics, and the mechanics of the process, will be applied to highlight areas at risk of overpressures and recommend proactive steps to mitigate them. Modifying process design to account for overpressures could create a headache that \"pounds more than a square inch\". What controls should be put in place to cater to these pressures, what measurement and monitoring equipment should be used, and does the risk of overpressures justify the economic implication of this additional equipment? And finally, do these measures compromise the performance of the facility? These are the questions that were answered in taming this \"Wild beast\".\u0000 In process design, pressure control is key to achieving operational continuity. Much like a perfect equestrian performance, a process operating within its design conditions can be very fulfilling. There is a great need to plan (design) to ensure your show horse (process fluids) responds appropriately to obstacles (process conditions) it meets along the way. The effect of pressure on flow, temperature, phase behaviour, and volumes makes it an indispensable tool to control process conditions.","PeriodicalId":220441,"journal":{"name":"Day 3 Wed, August 03, 2022","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132602973","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}

More specifically it is possible to define a marginal field as a field that is cost ineffective to develop with conventional oil and gas means of technology. Economic development of marginal fields in most cases requires the use of existing processes to minimize cost of finding evolving technologies in development of reserves. This paper generally evaluates the feasibility of using the enhanced oil recovery technique to improve reserves in a marginal field operation environment. A marginal heavy oil field in the offshore environment of the Niger Delta region which started production in 2011 is used as a case study to evaluate the feasibility of the use of enhanced oil recovery method to improve recovery. Due to poor mobility ratio in this heavy oil field and its associated big aquifer sizes, pockets of unrecovered oil have been left behind the water fronts and water cut has risen above 80% in most of the producing wells. Recent integrated field evaluation shows that the recovery factor is poor compared to the size of oil originally in place and this triggered the need to process subsurface assessments of developing such reserves that exist in any marginal field using enhanced oil recovery technique. This paper therefore goes through the fundamental scope of an enhanced oil recovery study process to determine the applicability of this technology in a marginal oil field.","PeriodicalId":220441,"journal":{"name":"Day 3 Wed, August 03, 2022","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133735116","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}
