Water management
This paper explores the development of direct-lithium-extraction technologies designed to recover lithium from unconventional feedstocks.
This paper reviews existing literature, the operator’s records, service-company data, and simulation studies to assess the risk of using seawater in carbonate acidizing.
This guest editorial from the Center for Injection and Seismicity Research (CISR) at The University of Texas at Austin details the emerging risks posed by injection in Texas and what steps might be taken to mitigate them.

Considering the current downturn in crude prices, there is a renewed interest in recycling produced water for reuse in hydraulic fracturing in the development of unconventional resource plays. -
If crude prices, rig counts, and tight oil production demonstrate a stronger upward trend in the months to come, US shale operators may find themselves with more produced water than they bargained for.
-
Geophysicists from Stanford University have compiled a map of new maximum horizontal stress orientations in Texas and surrounding areas, potentially giving operators new information for avoiding seismic activity in their hydraulic fracturing operations.
-
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.
