While this paper goes through all the main components of an integrated study (seismic, petrophysics, reservoir engineering), the main focus was on well data. This research focused on modelling the structure using mainly well data. The reservoir is associated with an alluvial cone structure and a canal system NNW-SSE, with the lithological traps in the southern part [1]. The reservoir pressure and the behaviour during production indicates a gas expansion is the main displacement mechanism, alongside a low influx of water. The results of this paper show that the performance of the reservoir is influenced not only by the available energy (the elastic gas expansion and a low influx of water), but also by the spatial distribution of different facies in relation to the well locations. Gas production started in 1962 and continues to this day. However, the Miocene reservoir was chosen for gas storage (UGS-Underground Gas Storage) due to its relatively large thickness, good porosity and large surface area [2]. The purpose of a reservoir characterisation is to incorporate existing data from petrophysics, geophysics, geological and reservoir engineering, so that the results obtained by the multidisciplinary team can be used to create a reservoir model which will improve economic results.","PeriodicalId":208076,"journal":{"name":"Romanian Journal of Petroleum & Gas Technology","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124643955","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}

A great economic shock was felt throughout this period and continued until the end of the year and even during the next year, but the extent of the damage is still uncertain, as is the speed and scale of recovery. Owing to the global lockdowns that resulted from the COVID-19 pandemic, gas consumption and production plummeted and the prices reached a new record low. \u0000As the pandemic started to spread in Europe the gas production went below the 2015-2019 range reflecting the decreasing trend of gas production in EU. In the same period 5 years ago the gas production was 36.6 bcm, more than twice as in Q1 2020, illustrating the rapid decrease in gas production in the block of 27 and the increase in import dependenc in natural gas. This study highlights the effects of COVID-19 on the gas markets based on publications of National Regulatory Authorities, Transmission System Operators, International Energy Agency, one of the world’s most trusted providers of data of global commodities markets and European Energy Exchange. \u0000Under the optimistic infection scenario, gas demand will recover close to the non-pandemic level by 2021. Unfortunately, the oversupply situation is improbable to be overcome promptly and in a more pessimistic way there is no visibility for a better business environment before 2023. \u0000\"","PeriodicalId":208076,"journal":{"name":"Romanian Journal of Petroleum & Gas Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130200152","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}

It is a thermodynamic property used to take into account the deviation of the behaviour of real natural gases from that of an ideal gas. Compressibility factor, Z, values of natural gases are necessary for most petroleum gas engineering calculations. In this study, a comparison between five different calculation methods is presented to determine this critical parameter for the same natural gas at different conditions (pressure and temperature), using Canadian Association of Petroleum Producers, Azizi, Behbahani and Isazadeh, Dranchuk- Purvis- Robinson, Dranchuk-Abu-Kassem and Standing- Katz methods. The correlations are based on the equation of state are often implicit because they require iteration. Many correlations have been derived to enhance simplicity; however, no correlation has been developed for the entire range of pseudo-reduced pressures and temperatures. Azizi, Behbahani and Isazadeh’s method was found to have the biggest error as a result obtained for T=20° C, and p=20 bar is no longer in the field of applicability.","PeriodicalId":208076,"journal":{"name":"Romanian Journal of Petroleum & Gas Technology","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129050513","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}
