This paper proposes a new approach to modeling pumps operating under multiphase-flow conditions.","PeriodicalId":22020,"journal":{"name":"Spe Production Engineering","volume":"49 1","pages":"413-419"},"PeriodicalIF":0.0,"publicationDate":"1991-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82247046","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 technique is based on the extraction, classification, and identification of stochastic features from turbulent pressure and void-fraction waveforms. Experiments in a horizontal air/water loop showed that a set of stochastic features is uniquely related to the individual phase flow rates. The software flowmeter is calibrated in situ by compilation of feature sets related to individual phase flow rates in a data base. On-line flow-rate measurement is made by a pattern recognition technique that identifies the best match to the measured feature vector from the calibration data base.","PeriodicalId":22020,"journal":{"name":"Spe Production Engineering","volume":"152 1","pages":"265-270"},"PeriodicalIF":0.0,"publicationDate":"1991-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79607496","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}

Both Alloy 625/API X-65 and Alloy 825/API X-65 tight-fit pipe (TFP) were evaluated under conditions of standard corrosion test environments to evaluate the metallurigical conditions fo the corrosion-resistant-alloy (CRA) liner tubes, long-term, full-scale TFP exposure under a simulated Mobile Bay production environment containing high levels of H{sub 2}S and CO{sub 2}, and hydrogen-permeation experiments designed to examine potential effects of CRA liner collapse from hydrogen produced by corrosion on the ID and/or cathodic protection on the OD. Results indicate that bimetallic TFP exhibited an acceptable metallurgical condition of the CRA liner materials. Under the simulated Mobile Bay production environment, TFP exhibited good resistance to general corrosion, stress-corrosion cracking (SCC), and liner collapse. Hydrogen-permeation tests indicate that very conservative estimates of service-life liner collapse from interfacial hydrogen pressure range from 150 to more than 800 years, depending on conditions. For all practical purposes, liner collapse from hydrogen is not a limiting factor for TFP flowline applications.","PeriodicalId":22020,"journal":{"name":"Spe Production Engineering","volume":"39 1","pages":"291-296"},"PeriodicalIF":0.0,"publicationDate":"1991-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84617893","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 analysis reveals two separate sets of solutions that correspond to two distinct time regimes of hydraulic fracture propagation: a dominant fluid dissipation energy and a dominant fracture surface energy regime. Each influence domain is governed by a characteristic time and demarcated by a transition region, where the energy contributions of each are of the same order of magnitude. Verification of the theoretical response trends and the use of the characteristic-time concept as a design tool are also presented.","PeriodicalId":22020,"journal":{"name":"Spe Production Engineering","volume":"46 1","pages":"323-330"},"PeriodicalIF":0.0,"publicationDate":"1991-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82496153","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}

Injection wells have historically exhibited large declines in injectivity and required frequent workovers. Because those declines were originally attributed to near-well damage from poor injection-water quality, a cleanup program was initiated that significantly reduced the amount and size of suspended particles in the injection water. Despite these improvements, injectivity continued to decline in many wells. Subsequent analyses of well histories, pressure-falloff tests, and reservoir petrophysical properties suggest that the reservoir damage in many instances was not only a sandface phenomenon, but also a result of deep particle invasion. Workover procedures were altered to treat the formation beyond the near-wellbore area, resulting in increased injectivities compared with the historical norm.","PeriodicalId":22020,"journal":{"name":"Spe Production Engineering","volume":"27 1","pages":"247-251"},"PeriodicalIF":0.0,"publicationDate":"1991-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81341377","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}
