Utility
High temperature submersible power cable
23 May 23
A method can include extruding an electrically insulating elastomeric compound about a conductor where the electrically insulating elastomeric compound includes ethylene propylene diene monomer (M-class) rubber (EPDM) and an alkane-based peroxide that generates radicals that form decomposition products; cross-linking the EPDM via radical polymerization to form an electrically insulating layer about the conductor; heating the cross-linked EPDM to at least 55 degrees C. to reduce the concentration of the decomposition products in the electrically insulating layer; and disposing a gas barrier layer about the electrically insulating layer.

Utility
Operating multiple fracturing pumps to deliver a smooth total flow rate transition
16 May 23
Changing a cumulative pumping rate of multiple pump units by adjusting individual pumping rates of the pump units, wherein each temporary dip or spike of an individual pumping rate of one of the pump units is automatically offset by a predetermined temporary adjustment of an individual pumping rate of another one or more of the pump units to thereby reduce effects of the temporary dip or spike on the cumulative pumping rate of the pump units.
