Experimental study and economic evaluation of low temperature drying treatment of abandoned water-based drilling fluid

, 2019
Abandoned water-based drilling fluids are the waste of oil drilling engineering operations. It will not only keep the cost of drilling fluid high, but also have a very adverse impact on the environment if it is directly discharged.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Flow Curves and Fluid Loss of Water-Based Drilling Fluids

Annual Transactions of the Nordic Rheology Society
A drilling fluid must fulfill numerous functions during well drilling, ranging from particle transport, lubrication, to wall stabilization.  In that aim, the composition is carefully chosen by the drilling engineer for each well section according to the required properties such as density, rheological properties, chemical stability, and fluid loss.
