Currently, about 65% of worldwide oil is produced by waterflooding, produced water re-injection (PWRI) and production with strong water support. Yet, formation damage is a serious obstacle for oilfield development. Intensive well and water management are necessary to prevent decline in well injectivity and productivity. This is the focus of the training course. We cover the major cases of formation damage, the corresponding reservoir physics, laboratory studies and mathematical modeling, and well behaviour prediction leading the optimal well and water management strategies.
"Smart water" is needed for effective waterflooding in carbonate reservoirs. A novel water-ionic technology, comprising nanofiltration and reverse-osmosis membrane-based processes, was identified for optimization in this study. The number of offshore facilities employing waterflooding with desalination continues to grow. Currently, more than 50 sulfate removal units are in operation offshore with a total capacity of approximately 8 million BWPD. How Does Low-Sal Water Work?
Oil and gas extraction using water has opened up new hydrocarbon resources. However they can produce four times more salty water byproduct than oil. Desalination in shale gas and polymer-flood EOR remain niche markets for lowering cost and improving production. Smart waterflooding by tuning injection-water salinity and ionic composition has gained attention in recent years. In this study, desalination technologies are reviewed with the objective to develop potential water-treatment solutions that can most efficiently alter injection-water chemistry.
Thank you for attending the SPE Workshop. This workshop focused on designing and managing efficient waterflood techniques and strategies for field optimisation, thereby increasing recovery and reducing costs. Subject matter experts and experienced professionals shared success stories, surveillance strategies, intervention planning programmes, new technologies for improved oil recovery, and ways-of-working for facilitating waterflood management.

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. This paper presents key challenges in surface-facilities-project implementation during the construction and operational-readiness phase of a project and presents results from full-field implementation. We report a novel type of viscosity modifier relying on the supramolecular assemblies that have pH-adjustable viscosities and robust tolerance against high temperatures and salinities, and are resistant to shear-induced degradation.
This paper presents the performance results from one of the waterflood pilots in the Viewfield Bakken. 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.
Early field tests suggest chemical treatments may be able to significantly increase production from unconventional formations. The low recovery rates observed in most shale reservoirs has prompted a number of research projects to develop new enhanced oil recovery methods. The Bakken’s ultratight, largely oil-wet nature limits the potential of waterflooding. As an alternative, an optimally spaced well-to-well surfactant-flooding technology is proposed.
This paper evaluates the incremental benefit of water injection in a conventional gas reservoir when compared with gas compression. This paper presents the performance results from one of the waterflood pilots in the Viewfield Bakken. 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. To increase the oil recovery in the Albacora field, significant water injection is required that was not considered in the initial project-development phases.
The chief upstream strategist of IHS Markit said in a recent presentation that oil exploration must improve its ability to deliver value and better communicate that value to the financial community. New ways of thinking about exploration opportunities are needed. Producers in Oklahoma’s newly opened Merge play are sitting atop a resource that rivals some major world gas fields and discoveries, Citizen Energy’s Geology CEO Greg Augsburger told the SPE Gulf Coast Section Business Development Group recently. The Austin Chalk play could go through a revival if the industry can view the formation through “a fresh set of eyes,” says EnerVest’s Tony Maranto. Dimethyl-ether (DME) -enhanced waterflood (DEW) is a process in which DME is added to injection water and, upon injection, preferentially partitions into the remaining oil.
