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.

Used extensively by the food, chemical, and pharmaceutical industries, the mechanical-vapor-recompression (MVR) process is viewed as a reliable method for recovering demineralized water from concentrated brines. This paper reports on performance of an advanced MVR system in north-central Texas. -
Hydraulic fracturing solutions use a gelling agent known as guar gum to transport proppant. Flowback water can have guar gum concentrations has high as 1% by volume creating treatment challenges prior to reuse or disposal.
-
With inconsistent inlet water quality being the rule rather than the exception, sizing and operational considerations of the treatment system components must vary accordingly to make the most economic sense.
-
In this study, a pilot plant with a capacity of 50 m3/d was used to conduct flotation, filtration, and adsorption trials for produced-water treatment at a crude-oil gathering facility.
-
The simplest way to measure return on investment for an offshore water treatment system is to determine whether using the system actually reduces the risk of paying a fine for violating water pollution laws.
-
The demands for the fresh water used in many hydraulic fracturing operations are placing pressure on water sources in some regions of the United States. Because of the high volumes of water needed for fracturing and competing demands availability of fresh water has decreased and costs have grown.
-
This is the fifth article in a series covering water management in hydraulic fracturing in unconventional resources. The focus of this article is biological control. Additives to improve fracturing conditions can have negative effects on water treatment.
-
A recent webinar focused on hydrocyclones and their application for offshore oil and water separation. The discussion includes fundamental science, practical considerations, implementation and field experience.
-
Polluted streams in Pennsylvania could provide a source of water for hydraulic fracturing and help prove a new way to clean up waterways contaminated by coal mine waste.
-
Produced water is an inextricable part of the oil- and gas-recovery process, and it is by far the largest-volume waste stream associated with oil and gas recovery.
