Paper presented at the SPE Improved Oil Recovery Conference, August 31–September 4, 2020
Paper Number: SPE-200314-MS
... Abstract Dimethyl ether (DME) is considered to be a potential Enhanced Oil Recovery EOR agent for enhanced waterflooding. Due to its first contact miscibility in hydrocarbons and partial high solubility in water/brine, it partitions preferentially into the hydrocarbon phase upon contact when...

Paper Number: SPE-200362-MS
... of mixtures of methane, CO 2 , and dimethyl ether (DME) with reservoir hydrocarbons including bitumen was studied to better understand the interaction of each solvent with reservoir fluids including water in the case of DME. The phase behavior models were then used in an equation-of-state compositional...

Paper Number: SPE-190242-MS
... the use of dimethyl ether (DME) and compared its efficiency in removing water and condensate blockage within hydraulic fractures with light alcohols such as MeOH. They showed that using DME results in higher efficiency since it is multicontact miscible with both water and condensate under reservoir...

Paper presented at the SPE Improved Oil Recovery Conference, April 11–13, 2016
Paper Number: SPE-179560-MS
... Abstract In this paper we present a novel Chemical EOR technique in which dimethyl ether (DME), a widely-used industrial compound is utilised as a miscible solvent in conjunction with conventional waterflooding. The end effect of the solvent's application is an increase in oil recovery...
