Water management
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.

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.

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.

When it comes to produced water from US shale plays, it’s either recycle and reuse or throw it away—and both are easier said than done.

Operators will not be able to inject wastewater below 10,000 ft in the Gardendale area.

The machine-learning techniques applied in this study aim to deliver a fouling-prediction model based on both simulation and real-time field data.

This case history explores a multiwell sectional development in the Delaware Basin by a small operator who reduced drilling and completion costs, along with lease operating expenses, by turning undesirable produced water into an asset.
-
A produced-water management framework is presented, forming part of an upstream-effluent management policy, to address the minimization and ultimate elimination of treated and untreated produced-water discharge.

As the oil and gas industry evolves to become more socially responsible with using natural resources such as water, economics constraints are an ever-present concern. The three highlighted papers share different approaches regarding how produced water could be managed economically.

This paper is the second of a two-part series. It covers facilities problems caused by iron, injectivity problems caused by iron, and the mitigation of colloidal iron-related problems.

The debate over whether to again allow briny waste water pumped from conventional oil and gas wells to be spread on Pennsylvania’s dirt roads has become as salty and charged as the material itself.
