Water management

Unwanted water production can erode well performance and asset economics if left unmanaged. Interwell’s precision water shutoff approach, grounded in diagnostics and engineered isolation, helps operators identify water-entry points, protect hydrocarbon flow, and restore sustainable well performance in mature and complex wells.
Ongoing seismicity concerns and orphan well risks are pushing operators and regulators to explore alternatives for managing produced water.
This paper describes a decision-support system that integrates field data, system specifications, and simulation tools to quantify system performance, forecast operational challenges, and evaluate the effect of system modifications in water management.

The Wyoming Department of Environmental Quality recently concluded that hydraulic fracturing operations were not the likely cause of well water contamination in a small town. -
Sourcing water for large multifracture stimulations in west Texas is a well-known constraint on oil and gas activities in the area. A 6-month pilot operation demonstrated that produced-water reuse is technically feasible and can be a cost-effective solution.

This paper summarizes the benefits of using a bipolymer crosslinking system in environments where water quality cannot be guaranteed. It also demonstrates the yielded cost savings per well that are achievable when reusing 100% produced or flowback water for hydraulic fracturing.

Water production normally increases as fields mature, and two main ways exist to deal with the produced water. One is to dispose of the produced water into dedicated disposal wells. The other is to reinject the produced water for pressure maintenance or sweep efficiency.

Earthquake in Cushing, OK -- home to the largest oil storage facility in the world -- leads to further regulatory action on disposal wells in the area.

Three metrics that are used for monitoring organics in water are total organic carbon (TOC), chemical oxygen demand, and biological oxygen demand. While less commonly used than the other two methods, TOC can offer practical advantages to operators.

Treating produced water to control bacteria is like weeding a garden. It addresses the problem that is not going away.
-
Analyzing the properties of produced water is a difficult process because of the extreme levels of suspended and dissolved particulates contained in it, and a chemistry profile that is in constant flux.
-
The presence of excessive levels of organic components in produced water can lead to costly problems for operators ranging from clogged membranes in treatment facilities to environmental issues and compliance with government permits.

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.
