Ferriere","doi":"10.2118/19935-PA","DOIUrl":"https://doi.org/10.2118/19935-PA","url":null,"abstract":"This paper reports on the engineering properties of foamed-cement slurries that were studied in detail with an original methodology based on new equipment. With this laboratory equipment, foamed cement can be mixed and characterized at pressures and temperatures representative of field conditions and at densities as low as 400 kg/m{sup 3}. The pressure and shear field under which a foam is generated are found to have a strong effect on bubble-size distribution (BSD), permeability, and to a lesser extent, compressive strength. Data on thickening time, fluid loss, and the effect of temperature on foam properties are also presented. A better understanding of foamed-cement properties allows optimization of job design so that prescribed pressure and density profiles in the column are achieved both during circulation and after placement. Critical design parameters are identified and their relative influence is shown through a case study.","PeriodicalId":22020,"journal":{"name":"Spe Production Engineering","volume":"429 1","pages":"297-304"},"PeriodicalIF":0.0,"publicationDate":"1991-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72588063","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 mathematical model matched or underpredicted the lifetime of the adsorption squeezes. Underprediction probably resulted from the exclusion of real phenomena, such as fluid crossflow and inhibitor precipitation. Both the model and the field data suggest that the most important design factor that determines squeeze life is the total amount of scale inhibitor injected. Equilibrium squeezes use a unique product that yields a longer treatment lifetime when designed properly. This process is more difficult to implement; it requires careful planning and quality control to be successful.","PeriodicalId":22020,"journal":{"name":"Spe Production Engineering","volume":"9 1","pages":"221-226"},"PeriodicalIF":0.0,"publicationDate":"1991-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80077945","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 sonic nozzles and master meter serve as flow-proving and -calibration devices. sonic nozzles are recommended by the turbine-meter standard for meter calibration. This paper examines the performance of on-site calibration of gas turbine meters. The Venice facility successfully demonstrated that on-site calibration of gas-metering devices can ensure accurate gas-flow measurement under field conditions.","PeriodicalId":22020,"journal":{"name":"Spe Production Engineering","volume":"13 1","pages":"161-165"},"PeriodicalIF":0.0,"publicationDate":"1991-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84590018","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}
