Water management
This paper explores the development of direct-lithium-extraction technologies designed to recover lithium from unconventional feedstocks.
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.
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.

Frac water disinfection experts become De Nora service arm in the unconventional oil and gas market. -
Operators in the Permian Basin are looking for new ways to handle the rising volumes of produced water coming out of the region without using saltwater disposal wells. One solution, treatment for discharge, could provide an efficient alternative.
-
Three papers selected from 2018 SPE ATCE look at the challenges and approaches to the treatment of increasing volumes of produced water.
-
Management of produced water is driving subtle yet potentially consequential changes in certain regions. Contributing factors for seismicity and well pressurization, while different, share some elements. By assessing these common elements, partial risk profiles for both conditions can be assessed.
-
Sourcing water for hydraulic fracturing, and disposing of produced water, are constraints and significant cost items in the Permian Basin. Some of the produced water can be treated and reused by using a water life cycle approach..
-
Volatile organic compounds (VOCs) present in crude oil can be released to the atmosphere from storage tanks, waste waters, and equipment leaks. A pilot-scale sequential biotrickling/biofiltration unit was designed and tested for removal of VOCs from a wastewater sump.
-
Finding water for hydraulic fracturing and then finding a use for it when it flows back are critical engineering problems to solve in the booming Permian Basin.
-
This paper describes a coreflooding program performed with sandpacks at different permeabilities, water qualities, and injection conditions.
-
Water management for unconventional projects continues to evolve at a rapid pace. What are some of the universal trends industry is adopting to handle higher produced water volumes and increased demand, and how do local dynamics impact the adoption of these trends?
-
Companies are bringing satellite monitoring to the unconventional oilfield—namely the Permian Basin—where they are training machine learning models to track and predict drilling and completions work.
