... the importance of imbibition in these systems. Our observations prove that water flooding, if applied at the most optimized mode that is a strong function of oil viscosity, can still be a very efficient EOR technique. waterflooding displacement oil viscosity enhanced recovery fluid dynamics viscous...

... Manville W. Polymer flooding was carried out immediately after primary recovery in Pool U but was carried out after waterflooding following primary recovery in Pool W, resulting in an incremental enhanced recovery of 20% in Pool U and only 10% in Pool W. This recovery difference can be attributed...

... expected and water breakthrough faster than expected. The initial Mangala FDP employed a conservative oil plateau production rate of 100 kbopd. Given its excellent waterflood performance, this was later increased to 150 kbopd. Watercut rise was as predicted for the uppermost Fatehgarh members (FM1...

Paper presented at the SPE Canada Heavy Oil Technical Conference, February 15–16, 2017
Paper Number: SPE-184966-MS
... Abstract Viscous fingering is a major obstacle to successful waterflooding in heavy oil reservoirs, as it results in water breakthrough and an undeveloped oil bank. To overcome viscous fingering, the composition of injected fluid can be tailored to a production scheme which optimally enhances...
