However, Algerian, Syrian, Iranian & Iraq will be examined as example for each type respectively,\u0000The study relies on a comparison between the items of the fiscal regime and the tools through which resource revenues flow to the public treasury as well as the share of the contractor or the company that holds the concession.\u0000Therefore, a model of fiscal regimes has been conducted for the above contracts to show the difference between the fiscal flows of each country according to the type of contract and the fiscal tools in it as royalty, taxes and others.\u0000The study demonstrated that the contracts vary in revenue ratios depending on the sale price of oil and the cost of extraction.\u0000Finally, we can clearly infer that the share of both the company and the state is affected by the above circumstances in a high or slight sensitivity, There is no particular type can be considered the best, as preference depends on the special circumstances of countries, for example, the Iraqi situation is difficult to use concession contracts for several considerations, including constitutional, where the Constitution of the Republic of Iraq specified the ownership of the people's oil wealth and this property cannot be relinquished to the investing companies and so on the rest of the countries, but it can be hybridized between some systems to obtain financial instruments that achieve the best choice for the parties (state and IOCs).","PeriodicalId":16710,"journal":{"name":"Journal of Petroleum Research and Studies","volume":"163 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77813942","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 causes many problems such as erosion and grains accumulation in downhole and surface equipment’s, and formation subsidence. Important stage in sanding problem solution is a prediction of likelihood sand production intervals. In present paper, a vertical well X1 that is producing from Asmari reservoir in Y field at southern Iraq was selected for study. Asmari reservoir was classified to six units: A, B1, B2, B3, B4, and C. B zones consisted from sandstone with others rock types. Eight approaches were used for prediction sanding onset intervals by dealing with X1 well as open hole completion. Utilized eight prediction methods are compressional sonic wave (CSW), unconfined compressive strength (UCS), total porosity (PHIT), shear modulus to bulk compressibility (G/Cb), B-Index, Schlumberger index (S- Index), combined index (Ec-Index) and critical drawdown pressure (CDDP). All these methods performed based on 2462 measured points of CSW, sonic shear wave log (SSW), and density log (DL). Sand production likelihood intervals was selected by determination of cutoff values of adopted methods. Sand is possible to occur if interval has values lower than cutoff values of G/Cb, UCS, B-Index, S-Index, Ec, and CDDP and greater than cutoff values of CSW, and PHIT. Obtained cutoff values of eight approaches were 800 x 109 psi2, 36 Mpa, 0.2, 80 us/ft, 10000 Mpa, 108 Mpa, and 2700 Mpa, of G/Cb, UCS, PHIT, CSW, B-Index, S-Index, and Ec respectively. As well as sand production is possible to occur of bottomhole flowing pressure lower than calculated CDDP. Some Intervals had high CDDP that referred to abnormal pressure zones consisted from shale. Determination of sand onset intervals is a key for selecting best methods for controlling.","PeriodicalId":16710,"journal":{"name":"Journal of Petroleum Research and Studies","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81004786","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}

Also, the conventional Iraqi crude oil is going to deplete according to the statistical analysis. Thus, methods of upgrading should attract attention in Iraqi fuel sector. The method of supercritical fluids (SCF) is one of the advanced approaches to upgrade the unconventional crude oil and removal of high levels of sulfur compounds. The present work aims at developing a kinetic model for upgrading reactions by supercritical water technology of a sour Iraqi crude oil. This aim was achieved via conducting sets of experiments in a hydrothermal autoclave reactor over a cobalt/activated carbon catalyst. The AC was used as a support for Co as an active metal. A set of upgrading kinetics experiments were applied at different temperatures (290-350 °C) and reaction times (0-45 min). Upon evaluation of the prepared catalysts for kinetics of upgrading by supercritical water technology, it was found that the process flows pseudo first order mechanism. Also, the activation energy of the chemical reaction was found to be 204.1 kJ/mol which is much less compared to previous studies","PeriodicalId":16710,"journal":{"name":"Journal of Petroleum Research and Studies","volume":"124 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89268218","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}
