Although emphasis is placed on those methods used in our laboratories, discussion of other work available in the literature is also included. The relative merits and limitations of the frequency- and time-domain techniques are evaluated. Some representative results illustrating the variation of the complex permittivity of oil shale as a function of frequency, temperature, and grade are given. The paper is concluded with the description of an in-situ dielectric probe which utilizes an open-ended section of transmission line as a sample holder. Experimental results illustrating the accuracy of the on-line measurements are presented and suggestions for the future development of the in-situ probe are discussed.","PeriodicalId":76653,"journal":{"name":"The Journal of microwave power","volume":"5 1","pages":"55-74"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84671387","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}

One solution to this problem is the addition of heat to the oil flowing. A rough rule-of-thumb for most heavy oil is that heating the formation by about 5°C would cut the viscosity of the oil to half of its original value and, likewise, increase the flow rate by a factor of 2. The electrothermic system is designed to increase the flow rate of oil by accomplishing the following tasks: (1) Heat the entire flow string plus the down hole pump and pump rods so that the pump will work more efficiently and the viscosity of the oil in the flow string will be greatly reduced. (2) Heat out into the oil reservoir to a considerable distance from the wellbore, thereby increasing oil flow into the wellbore because of reduced viscosity. (3) The system also moves water away from a producing wellbore, thus incr...","PeriodicalId":76653,"journal":{"name":"The Journal of microwave power","volume":"42 1","pages":"107-110"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80614074","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}
