This innovative solution integrates a new state-of-art Rotary Steerable System (RSS) with Managed Pressure Drilling (MPD) technology. Drilling hazards such as total losses, wellbore instability and stuck pipe were mitigated, and an improved drilling performance with reduction of NPT as compared to other directional drilling systems.\u0000 The solution requires the integration of two highly technical disciplines, MPD and Directional Drilling (DD). Hence, a Joint Operating & Reporting Procedure (JORP) and a defined communication plan are crucial for the effective execution. The solution is based on a rigorous Drilling Engineering process; including detailed offset wells analysis to deliver a comprehensive risk assessment & mitigation plan in collaboration with the operator to tackle drilling hazards without compromising the directional drilling requirements.\u0000 The paper will also discuss the effective communication plan between the directional drilling services, MPD services and rig contractors to ensure safe operational alignment. Also, the paper includes a planning and operational blueprint to reduce NPT related to total losses, stuck pipe & wellbore instability, increase drilling performance (ROP improvement) and quality wellbore for liner run afterwards in the Middle Cretaceous formation.\u0000 Drilling challenges in the Zaap field requires the utilization of both Directional Drilling technology and MPD techniques to improve drilling performance and reduce NPT respectively. Through processes, best practices and lesson learned, this paper hope to serve as the bellwether for the combined solution to achieve technical limit drilling performance in the Zaap field, offshore Mexico.","PeriodicalId":164814,"journal":{"name":"Day 3 Wed, July 29, 2020","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121428713","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}

{"title":"Use of Foams EOR in Piedemonte Fields - A Successful Mechanism to Improve Gas Sweep Efficiency in Low Porosity and Naturally Fractured Reservoirs","authors":"A. Ocampo, A. Restrepo, J. Clavijo, Harold D. Cifuentes, J. Mejía","doi":"10.2118/198982-ms","DOIUrl":"https://doi.org/10.2118/198982-ms","url":null,"abstract":"\u0000 This paper presents the development and successful implementation of the Foams technology as an effective EOR mechanism to improve the sweep efficiency of the gas injection in the Piedemonte fields. It also shows the process of optimization of the technology to adapt it to the Piedemonte operating conditions, which is based on massive hydrocarbon gas reinjection, and how this process led us to be at a state of the art position in this technology.\u0000 The methodology to adapt and further develop the foam EOR technology in Piedemonte was based on the Capital Value Process (CVP). It starts with a screening exercise, passes through a technical assurance including applicability, fluids compatibility, modeling and coreflooding tests at reservoir conditions. Finally, the specific solution is implemented in the field to confirm effectiveness. Initially the foams were deployed using the conventional Surfactant Alternating Gas (SAG) technique, but then the technology was optimized to better suit the operating conditions of the fields, and the last interventions have been done dispersing the foamer chemical in the gas stream.\u0000 This technology has been implemented in most of the fields in the Piedemonte and has proved success since the early implementation pilots in 2011. Implementation started in the Cusiana field, which is a matrix dominated system, and then moved to the naturally fractured and low porosity reservoirs located in the Recetor and Floreña fields. In all the cases, the implementation of foams has rendered positive results reflected in incremental oil production and flattening of the Gas Oil Ratio (GOR) at the influenced producer wells. The new developed dispersed Foams technology has been as effective as the conventional SAG in the jobs performed so far, with the advantages of requiring less surface equipment, and water consumption than SAG jobs. Benefits from Foams implementations so far add up to about 0.65 MM STB.\u0000 Main conclusions from this project are i) The foams EOR technology is fully applicable in the Piedemonte fields to improve the gas sweep efficiency and increase final oil recovery. ii) A new foam deployment technique based on the injection of the foamer chemical dispersed in the gas stream was developed, and proved effectiveness at the field.\u0000 The work is innovative in two ways: i) Effectiveness of foam as a technology to improve gas sweep efficiency in naturally fractured dominated systems was proved. ii) A new foam deployment technique based on the injection of the foamer chemical dispersed in a non-condensable gas stream was developed. Also this new foam EOR technique can be extrapolated to any other field operated under gas injection.","PeriodicalId":164814,"journal":{"name":"Day 3 Wed, July 29, 2020","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116815394","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}

Augmented Reality (AR) or Mixed Reality (MR) technologies have tremendous potential to meet these challenges by providing realworld digital landscape to intuitively interact with data, train personnel, and mitigate process safety risks.\u0000 However, a major challenge with AR and MR technologies is the limited processing power and capability of available hardware. A cloud-based software platform can overcome these computational limitations of AR and MR devices, enabling interaction with significantly more complex 3D content. Additionally, enabling real-time connectivity across different hardware architectures – such as smartphones and Microsoft HoloLens devices – creating powerful new capability for remote collaboration. This unique software platform transforms consumer-grade AR and MR devices into powerful industrial tools for oil and gas applications.\u0000 This paper will illustrate the application of AR/MR technology in critical risk management including the adoption of AR/MR technology for process safety operational readiness and response capability to critical risk associated with major accident hazards. Enhanced AR/MR provides full-scale virtual digital landscapes that enable practical demonstration of crew resource management including the evaluation of collaborative human performance in teamwork activities. Using gamified AR/MR techniques, allows for multiple outcomes based on user inputs to test decision-making and eliminate human errors. These enabling technologies can drive significant improvements in process safety risk management while increasing operational efficiencies across the oil and gas industry.","PeriodicalId":164814,"journal":{"name":"Day 3 Wed, July 29, 2020","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130375334","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}

Martins, M. Manuel, Thomas Merzi, S. Canovas, A.

The document presents the strategy and summarizes the results of indicators which are used to follow up cumulative impacts on deep water environment. The campaign was performed between 1998 and 2015, and different laboratories were used. The impact of field operations proved to be rather low or negligible, and acceptable on the long term.\u0000 Since February 1998, when the first environmental baseline study (EBS) was performed (in Block 17: Girassol) to describe the initial state of the environment, the Affiliate has been conducting regular offshore monitoring campaigns with the aim of characterizing the water column, and marine sediments around existing installations and developing fields. These surveys are not limited to Block 17, but also extend to other Affiliate offshore blocks in Angola.\u0000 In March 2015, the Affiliate’s most demanding Global Environmental Baseline & Monitoring Survey (GEMS) was completed, which covered six different offshore blocks, with a work scope ranging between EBS and EMoS (environmental monitoring survey), comprising 226 sampling stations for sediment and benthic macrofauna, 26 for seawater, 17 for phytoplankton and 8 for foraminifera. Another specificity of this latest GEMS was the scientific vessel that was shared among Operators through a joint agreement, of course with some legal and operational constraints considering the socio-geographic context of the project. Technically, besides the Affiliate’s required guidelines and rules, the parameters to be tested also had to meet recent regulations from the Ministry of Petroleum. Physico-chemical and biological data obtained over the past 17 years have been used as indicators of environment quality, and its regular monitoring allows assessment of the sensitivity of the marine environment to petroleum activities.","PeriodicalId":164814,"journal":{"name":"Day 3 Wed, July 29, 2020","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121064564","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}
