... economic parameters. Thus, the use of polymer flooding over waterflooding is attractive. However, the predicted value changes meaningfully between the scenarios, emphasizing that a simulation model should be taken as a "living forecast". Subsequently, an economic sensitivity analysis is conducted...

...Introduction Waterfloods have been the most widely used secondary recovery technique in conventional reservoirs. In any such recovery process involving water injection, understanding the flow efficiency between the injection and the producing wells becomes paramount, which leads to the study...

... injection displacement process will be implemented as a secondary recovery process (before waterflood) rather than tertiary method (after waterflood). This paper will report a new systematic workflow for integrating ultra-high pressure laboratory PVT and slim tube data and high resolution mega static earth...

Abstract Potentially generating an estimated $1.3 million in net present value, a proposed pilot waterflood in the Permian Basin of West Texas was determined to be technically and economically viable by using a reservoir model and analog data. Located in Winkler County, the lease has produced...

However, additional infill drilling was done following the implementation of the waterflood, and in that situation it is difficult to determine what additional production is additional primary recovery...

... Where J e = k ¯ h J ˜ Abstract A major challenge while implementing waterfloods is estimating flow heterogeneity and potential water cycling issues. Core data, being static, does not accurately represent flow in a reservoir. Isolated zones may only contribute near...

...Methodology This section describes the two-dimensional reservoir parameters chosen and foam models implemented for the simulation study. A waterflood, a WAG flood, and a SAG flood were carried out separately on each of the reservoirs to compare the performance of foam flood in a reservoir (SAG...

... and underburden formations by using a no heat flux boundary condition. We injected 2.0 PVI of water at two different temperatures and then CO 2 continuously for another 1.0 PVI at the same temperature as the injected waterflood temperature. The incremental oil recovery is the additional oil recovered by CO 2...

... Abstract Improved and enhanced oil recovery (IOR/EOR) processes, such gas injection and waterflooding, are difficult to model accurately in fractured reservoirs due to complicated multiphase physics and the strong property contrast between permeable natural fractures and tight matrix rock...

... Abstract Low salinity waterflood (LSW) is a relatively new enhanced oil recovery (EOR) technique which has been reported to improve oil recovery in several laboratory experiments and some field trials. The general assumption among researchers is that LSW shifts wettability towards a more...

... Abstract Alkali-surfactant injection after a short waterflood can improve the recovery of very viscous oils of the order of 10,000 cp or above in corefloods. The goal of this research is to understand the pore-scale phenomenon behind these observations. Several secondary and tertiary floods...

... The first low salinity waterflood recovered 14% more oil than the first high salinity waterflood. LSBC – 1 also reduced S or by 6.5 saturation units, decreased end-point water relative permeability by 18% and increased end-point oil relative permeability by 9%. After the core was exposed...

... with a combination of alkali and surfactant at 25°C. Waterflood had an early breakthrough at about 0.3 PV and recovered about 0.61 PV of oil in 3 PV throughput. Injection of tertiary alkaline-surfactant-polymer slug followed by tapered polymer slugs could recover almost 100% of the oil. The pressure drops were...

... pressure depletes. For waterfloods, on the other hand, reservoir pressure is generally maintained at a certain level and the oil production decline is caused by reduction of oil saturation and oil relative permeability. In this case, the oil production for waterflood does not directly depend on time...
