... volume injection. In other words, the sweep efficiency improves in the nine-spot pattern configuration compared to the five-spot pattern. This also makes sense from physical point of view where the injected water is distributed more evenly when surrounded by eight producers when compared with only four...

... The degree to which injection water will "slump" under gravity within Zone_1 as water advances from injector to offset producer will be determined by injection fluxes and the presence/absence of low Kv intra-zonal layers, but injection water "holding up" in the upper Zone_1 has been observed...

... the result of the field trial conducted in March 2018, which yielded 40 kbbl of oil gain and a 5-10% reduction in water cut during two years. The field trial took place in a mature water flood pattern with 100-meter well spacing, involving a horizontal water injector and two adjacent oil producers. Over...

... producing since 2007 for testing purposes. It was officially commissioned and commenced production in Q1 2013, peaking at 22 MBOPD from the A and B reservoirs. In 2020, the C reservoir was brought to production, providing promising oil in place to offset the decline in the A and B reservoirs. All wells...

Upon acquiring positive one-spot EOR pilot results, it was decided to proceed with a regular 5spot water-flooding/polymer-flooding pilot composed of 4 injectors, one producer, and one disposal well...

A combination of remaining oil saturation maps of producers and the impact of displacing fluid viscosity from the model...

..., and the second field went through the same procedure. Pulse waterflooding was applied to the north and south parts, divided by the extensive gas cap of the A field. Most producers in both parts exhibit a clear trend of not only stabilization but also gradual growth. That was mainly reached due to an increase...

Results of the first oil producer well are presented, showing the well is producing oil with almost zero water cut. This is in contrast with the nearby wells and contrary to the expected higher water saturation...

... Abstract Primary recovery and extensive waterflooding lead to preferential pathway for the water between injectors and producers, resulting in low sweep efficiency and lower oil recovery. The Lamadian Oilfield in Daqing has been waterflooded for 50 years, where various methods have been tried...

... Abstract Water flood is dominant development mechanism to produce oil from lower Shuaiba carbonate reservoirs in North Oman. Efficient water flood management along with a novel approach to drill infill wells has resulted in increased oil production at lower GHG intensity while reducing cost...

... infill drillings, EOR polymer flood and ASP flood. Strong reservoir heterogeneities, producing at water-cut >90% starting in 1999, various IOR/EOR activities and several well-pattern types overlapping vertically led to extreme challenges for further improving waterflood recovery. This paper first...
