Drilling/completion fluids
One major challenge for drilling-fluid engineers is the design and management of optimal drilling-fluid formulations in emerging frontiers—fractured formations and high-pressure geothermal environments. Recently, operators have leveraged cutting-edge technology such as machine learning and expanded data-driven techniques to facilitate the development of new drilling-f…
This research aims to develop a fluid-advisory system that provides recommendations for optimal amounts of chemical additives needed to maintain desired fluid properties in various drilling-fluid systems.
This paper describes development of a high-temperature water-based reservoir drill-in fluid using a novel synthetic polymer and customized with optimal chemical concentrations and sized calcium carbonate.

Always recorded but almost never used, the water hammer signal could offer completions engineers another set of insightful data if petroleum engineers can crack its code. -
For nanotechnology-based drilling fluids, acceptance means proving they can outperform other drilling fluids. Initial results have been encouraging enough to move toward commercialization.

A long-time energy industry executive and chemical engineer has built a new water treatment system that he says can increase recovery rates from shale wells without using chemicals and will recycle all the water used in the process.
-
The inventor of a new water-based drilling fluid believes the chemical process involved with his technology opens up natural fractures as drilling takes place to increase production in shale formations.
-
A challenge in many permeable, water-sensitive, subhydrostatic reservoirs is avoiding the loss of completion fluid when completing or working over wells.
