Geographical and political dynamics of the Central Asian countries help the countries to stand out as a significant stable and sustainable source of energy in the region with great resources of supply and low domestic demand. This study outlines economic and technical analysis of oil and gas resources of central Asia under demand and supply dynamics of world hydrocarbon production. A comprehensive literature review has been carried out to investigate the basins and major oil and gas fields of the region, their development from the beginning, the technologies utilized, types of recovery processes, supply capabilities and potential of future supply are addressed. Real field applications are illustrated with applications in different parts of the region with challenges, advantages and drawbacks discussed and summarized in comparison to other major energy hubs of the world and their major oil and gas fields and basins. Central Asia is a relatively young and dynamic region with growth potential of harnessing the great and relatively new resources. Due to the political and geopolitical dynamics of the region, Central Asia serves as a strong and stable provider of energy obtained from fossil fuels. Low domestic demand in the region makes it more attractive in terms of the amount of export potential. There is no recent up-to-date study that investigates and outlines not only the technical characteristics of fields, reservoirs and basins in the region but also the demand/supply dynamics of the resources in the regions as they compare to the other major energy hubs in the world. This study comparatively outlines the key elements of successful applications in the region along with the lessons learned from challenges as well as the current and near-future potential of Central Asia as an energy hub in the world.","PeriodicalId":215989,"journal":{"name":"Day 3 Fri, November 02, 2018","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130781863","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}

The TCO IOC approach has been established in both Plants and Field Operations to perform rigorous planning of short and long-term activities, improve communication between operational teams (Field Operations, Plant Operations, Reservoir Management Group, Process Engineering Team, Projects Team, etc.) and increase production efficiency at the Field and Plant level. Two key objectives of the IOC are to utilize an Integrated Asset Management approach to ensure field deliverability is available to maintain plant production demands throughout the year, as well as to utilize planned/unplanned facility downtime to execute field facility maintenance and project scope, reservoir surveillance jobs, etc.\u0000 The IOC collaborative environment allowed TCO to improve production efficiency in the field and at the Plant by establishing a clear communication bridge between multi-discipline groups, and implementing a \"conflict resolution\" process, which enabled all relevant groups to perform integrated planning. The overall IOC process has added more than 15,000 bbls of daily production.\u0000 One of the key components to the success of the Integrated Asset Management approach was to embed a production engineer in the IOC to ensure field work scope decisions and scheduling are based on short and long-term production deliverability.\u0000 This paper outlines how a real-time system can be used for production planning optimization, resource allocation and integrated plan development. The paper includes a discussion of how the Integrated Asset Management approach can be utilized in an operation center to address some of the challenges associated with production planning in field operations.","PeriodicalId":215989,"journal":{"name":"Day 3 Fri, November 02, 2018","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116688983","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}

The case study was performed in Lam and Zhdanov fields operated by Dragon Oil, Offshore Caspian-Turkmenistan. The objective was to enhance the quality of well testing and allocation factor by comparing test separators (TS) measurements against multiphase flow meter (MPFM) readings and, in a bigger scope to converge the difference versus onshore plant measurements of oil and water.\u0000 Commissioning stage of MPFM was started off by comparing its results with TS. Comparison program was made and followed by considering the operating envelope of both technologies: MFPM and TS, input PVT parameters, measurement conditions and success criteria. Water-liquid ratio (WLR) and water rate from MPFM was compared against wellhead samples utilizing automatic centrifuge and total water at plant.\u0000 MPFM was subjected to measure flow during both: well clean-up stage and production logging of a slugging well. High gas volume fraction and scale/wax precipitation have required methodology development to maintain the accuracy of MPFM.\u0000 14 wells were subjected to comparison test showing differences in gas and liquid rates between MPFM and TS are within acceptable criteria while difference in water rate was high due to slugging nature of flow. High-frequency measurements of WLR from MPFM showed water rates accompanying slugging were consistent with wellhead sampling and total onshore water production. Two-phase test separator was underestimating the water due to few sampling and improper separation at manual centrifuge.\u0000 In high gas volume fraction equal to 98.5% and above MPFM accuracy in liquid rate becomes very sensitive to reference point of gas. To maintain the liquid accuracy, the in-line measurement of gas point was done so that accuracy of liquid measurements improved.\u0000 MPFM has identified wells with scale and wax precipitation, which can be observed from photon counts deviation at two energy levels of gamma-ray spectrum. By adding 3rd energy level, it was possible to estimate the thickness of scale and wax on the wall of meter venturi throat and hence maintaining the MPFM flowing rate accuracy.\u0000 MPFM campaign showed accurate measurement of water for Cheleken in addition to adding efficient well testing frequency while providing reliable high data frequency. This case study shows the first mobile MPFM application in Caspian offshore for producing wells’ testing. Results in comparison with TS signifies better and faster ways to calibrate the surface TS. MPFM testing campaign has led to the early identification of possible flow assurance issues and consequently, development of methodologies and recommendations to ensure reliability of MPFM and permanent test separators.","PeriodicalId":215989,"journal":{"name":"Day 3 Fri, November 02, 2018","volume":"385 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127462396","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, complexity of the internal structure, variation of depositional environments and rock types of these formations makes the process of reservoir characterization extremely difficult for exploration, further well placement and field development planning. Natural fractures complicate the reservoir dynamic behavior even more, resulting in very diverse well performance and high watercut across the field.\u0000 In this study, we try to reveal the reservoir nature, distribution and properties by integrating seismic, wellbore and regional geological data. The study is based on the data of Bulak oil field. Operated by PetroKazakhstan Kumkol Resources JSC, this is a unique oil field producing from Carboniferous reservoirs within the Aksay horst of the Aryskum trough. Considering well penetration intervals are limited to pay zones, the complex internal reservoir structure and properties were characterized by integration of methods such as seismic chromatic geology extraction, seismic inversion, volumetric petrophysical modeling, regional stress analysis, 3D static and dynamic modeling (DPDP) and others.\u0000 As a result of the study, different conclusions were made regarding the structure, distribution and properties of the main reservoirs, development of different fracture types and resulting dynamic field behavior. Compressional regime in the Late Paleozoic - Early Mesozoic eras and associated structures were identified and mapped; two main trends defining the reservoir architecture were identified: uplift of the whole section towards the North and the tectonic forces that created and overturned fault blocks to the Southwest; general decrease of carbonate content and increase of shaliness from Early to Late Carboniferous were observed; abundance of near-vertical open fractures in the Northern part of the field (as opposed to lower dips and possible mineralization of fractures in the Southern part) was identified and modelled; main hydrocarbon bearing rock types were described and attempts to identify them across the field were made.\u0000 Being one of the first fields commercially producing from Paleozoic rocks of the Torgai basin, Bulak revealed a lot of information that is being used for further exploration in the area. Different field feature trends can be extended to neighbor blocks and existing data can be used as analogues, especially based on seismic features where no wells are drilled yet.","PeriodicalId":215989,"journal":{"name":"Day 3 Fri, November 02, 2018","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116000466","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}
