... wells within Marmul field. The new vertical infill patterns will interfere significantly with the current well stock of the field. One of the activities called for by the field development plan is to abandon the horizontal wells that would cause interference and disturb the sweep efficiency of the new...

... their surrounding producers. Injector's efficiency, allocation factors and reservoir sweep efficiency are calculated using the simulation model. Both approaches are compared to have a better evaluation of the waterflood. When the waterflood started, a regular i-9 spot patterns was the way to develop the reservoir...

..., and occupied large intra-particle pores. Gel had a good plugging performance on channels with high permeability. The following steam bypassed the mainstream channels for further residual oil flooding. Oil flooding results showed that posterior to gel solution, the final sweep efficiency could reach 70.44...

... to estimate the sweep efficiency/ swept pore volume, and to estimate Lorentz coefficient (Lc). The estimated Lc from tracer analysis matches with the Lc being used in the simulation models. For assessment of EOR potential in Fatehgarh formation, chemical EOR pilot consisting of four injectors and single...

... and analytical tools were applied to investigate ongoing waterflood in different levels (area, reservoir, and well). The sweep efficiency plots were used to compare the waterflood efficiency among 13 different areas in Sirikit field. The impacts of key parameters including injection duration, pore volume...

A strong monitoring plan, including an observer well, was applied through time-lapse saturation logging, pressure measurements, production testing...

... were screened and benchmarked against the fine scale performance characteristics using layer sweep efficiency as the main optimization criteria. This practical workflow jointly optimizes the geological and engineering upscale layer requirements and facilitates transition to the history match process...

... Abstract The existence of high-permeability features, such as fissures, fractures, and eroded-out zones, diminishes the sweep efficiency of any water, gas, or polymer flooding operation. Placing crosslinked conformance polymer gels or other types of blocking agents in injection...

... Abstract Due to severe heterogeneity of thick positive rhythem reservoir and the gravity influence, the injected water channels and ineffectively cycles through its lower high permeability zones. For the whole reservoir, its sweep efficiency is relatively low and a huge amount of residual oil...

... Abstract Water-alternating-gas (WAG) injection is an enhanced oil recovery (EOR) method aimed at increasing sweep efficiency by contacting zones that are not adequately swept by water injection and by increasing microscopic displacement efficiency as gravity-aided WAG injection often gives...

... while giving poor sweep efficiency. In order to achieve the target injection rate with 5 injectors, two appropriate aquifer dimensions are proposed: an area of 3,850 km2 with thickness of 1,260 m; and an area of 11,550 km2 with thickness of 630 m. For the same aquifer volume, thickness plays a more...
