Previous studies on chalk suggest that exposure of a large amount of acidic crude oil to core material reduces water wetness, thus affecting the ultimate oil recovery achieved during waterflooding. Presence of silica in the pore space appears to affect the wetting state of chalk toward more water-wet conditions. This study evaluates the wetting effect of crude oil exposure on the silica-rich Aalborg chalk, and its impact on oil recovery. Spontaneous imbibition and forced imbibition tests have been conducted at 50 °C to evaluate initial wetting and its effect on oil recovery from three silica-rich (6.8 At%) outcrop Aalborg chalk cores. Various amounts of crude oil was injected during core preparation, and it was observed that as the amount of crude oil injected increased, less water-wet conditions were obtained. A higher degree of water wetness in the Aalborg chalk core promoted higher ultimate oil recovery under forced imbibition than that previously reported for Stevns Klint chalk, containing low silica content. It was concluded that the silica content in the core induced a more water-wet wetting state in the core.","PeriodicalId":6840,"journal":{"name":"81st EAGE Conference and Exhibition 2019","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82856526","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 waterflood front positions are interpreted on 4D seismic amplitude difference maps and the flood front is modelled in analytical PTA. The asymmetric flood front is investigated in a numerical PTA model and parameter sensitivities for matching both the 4D seismic interpretation and the pressure falloffs tests are explored. The workflow allows for iterations in the interpretation of the 4D flood front as well as updates to the parameters used in the numerical PTA until a satisfactory model is created which matches both the 4D seismic data and the pressure falloffs used in PTA. Together, the joint iterative analysis helps to reduce uncertainty in the products delivered by the individual techniques, resulting in quantitative flood front positions that can be used in assisted history matching of reservoir flow simulations. The case study establishes the value of utilizing 4D seismic in an integrated workflow with PTA techniques for generating flood front constraints that aim to improve forecasting models and guide reservoir management decisions.","PeriodicalId":6840,"journal":{"name":"81st EAGE Conference and Exhibition 2019","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82810258","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}

An alternative and faster approach is to divide the large sample into subvolumes (elements), and use the LB method on each element. The permeability of the host sample is then obtained by Darcy's simulation on a synthetic volume comprised of the elemental permeabilities. The results of the first and the second method are practically identical in this example. Using subvolumes also helps produce a physically meaningful permeability-porosity trend from a single digital object. These results are likely to be valid only in samples with well-connected and homogeneous pore space. A counterexample comes from carbonate where appreciable part of the pore volume is located in vugs. Here the permeability-porosity trend formed by the majority of the subsamples exceeds the permeability of the host sample by about half of an order of magnitude due to the enhanced connectivity when dividing the host across the isolated vugs.","PeriodicalId":6840,"journal":{"name":"81st EAGE Conference and Exhibition 2019","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89018538","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}
