Water management
The paper presents a system for separation of water in downhole horizontal wells in which the water produced from the well is not lifted to the surface but reinjected into the reservoir.
The machine-learning techniques applied aim to deliver a prediction model based on both simulation and real-time field data. The model tracks and monitors system key performance indicators.
Even though total produced volumes are projected to hit new record highs in the coming years, treated water is expected to be comparatively lower than in the past, despite water disposal practices increasing oilfield seismic activity, with earthquakes nearly doubling in West Texas alone in 2021.

A subsidiary-owned pipeline near Marmon, North Dakota, spilled more than 700,000 bbl of produced water over a period of almost 5 months in 2014–2015.

Signed into law last month, the Texas Produced Water Consortium will be hosted by Texas Tech and bring together stakeholders, key experts, and industry to address produced water challenges.

A 2-year study of a formation used for saltwater disposal in the Bakken may hold promise of decreasing the pressurization of the formation and increasing the reuse of the briny produced water.

This latest project will build on a previous initiative with up to a trio of field trials aimed at supporting regulatory authorities and industry to establish new standards and practices for the use of online oil-in-water analyzers at remote locations.

Acknowledging the necessity to better understand treatment needs, economic challenges, and public health and environmental risks of industry’s waste water, the Texas Legislature recently passed Senate Bill 601, establishing a Texas Produced Water Consortium.

In the original grant application for renewable desalination, the startup mentioned solar thermal, but Gary Katz had originally thought industrial waste heat energy would be the ideal source. But, as he noted ruefully, “As a startup, you have to pivot to what the market will support."
