Study Investigates Smart Waterflooding in Sandstone Reservoirs
In this paper, the authors consider the effect of water chemistry on water/rock interactions during seawater and smart waterflooding of reservoir sandstone cores containing heavy oil.
Surface-to-Borehole Electromagnetics Hold Promise for 3D Waterflood Monitoring
The authors detail the development of a technique based on surface-to-borehole controlled-source electromagnetics (CSEM), which exploits the large contrast in resistivity between injected water and oil to derive 3D resistivity distributions, proportional to saturations, in the reservoir.
Production Optimization in Waterfloods: A New Approach to Interwell-Connectivity Modeling
In the complete paper, the authors present a novel methodology to model interwell connectivity in mature waterfloods and achieve an improved reservoir-energy distribution and sweep pattern to maximize production performance by adjusting injection and production strategy on the well-control level.
Numerical Modeling of Unstable Waterfloods and Tertiary Polymer Floods for Viscous Oils
This paper addresses the challenges in modeling highly unstable waterflooding, using both a conventional Darcy-type simulator and an adaptive dynamic prenetwork model, by comparing the simulated results with experimental data including saturation maps.
Integrated Approach To Managing Formation Damage in Waterflooding
Understanding of formation damage is a key theme in a waterflood project. An integrated multidisciplinary approach is required to determine an optimal design and strategy.
A Full-Field Interwell Tracer Program on a Giant Carbonate Oil Field
This paper reviews the design and implementation of a full-field interwell tracer program for a giant onshore oil field in Abu Dhabi.
Custom Biological Produced Water Treatment Yields Fast Oil Recovery Boost in Waterflood
This article describes how the use of a biological EOR technique that applied produced water for reservoir flooding in a mature field led to rapid and substantial increases in oil production.
Understanding Waterflood Response in Tight Oil Formations: A Saskatchewan Case Study
An 18-well numerical-simulation model was built to represent an operator’s Lower Shaunavon waterflood-pilot area. Numerical simulation was used, and a history match on the pilot area was performed.
Waterflooding Proves Useful in Deepwater Gulf of Mexico Overpressured Turbidites
This paper is a detailed examination of Pleistocene-to-Upper-Miocene turbidite reservoirs in the deepwater Gulf of Mexico under water injection.
