A Compact Hollow Fiber Electrode Assembly Architecture for Continuous Electrochemical Marine Carbon Dioxide Removal

open access: yesAdvanced Energy Materials, EarlyView.
A coaxial, membrane‐integrated hollow fiber electrode assembly (HFEA) is developed for continuous marine carbon mineralization. By utilizing a sub‐millimeter inter‐electrode gap, the HFEA minimizes Ohmic losses, achieving 50% energy reduction and over 85% DIC removal.

A Novel Drilling Fluid for Underbalanced Drilling

Proceedings, 2009
Interest in underbalanced drilling is growing worldwide. UBD, when properly designed, eliminates problems associated with the invasion of particulate matter into the formation. However, experience has indicated it is difficult to maintain a condition of continuous underbalance pressure throughout the complete drilling operation, resulting in fluid ...

The Drilling Fluid

1985
This section presents a limited description of drilling fluids. A complete discussion of drilling fluids (mud types, chemical treatments, solids control, water loss, and so on) is beyond the scope and intent of this manual. A more detailed discussion may be found in Section 4 of the Field Geologist’s Training Guide (MS-178).
