Abstract: Systems and methods for automatically adapting operation of an electric drive system for an electric submersible pump (ESP). A control system for an electric drive receives live measurements of operating conditions of the ESP as the ESP is operating. The control system calculates adjustments to settings of the electric drive which generates output power that drives the ESP, where the adjustments are calculated based at least in part on the live measurements, and without user intervention. The control system thereby automatically controls the drive to modify the output power provided to the ESP, which in turn controls the operation of the ESP. The adjustments may increase the stability of the ESP's operation, improve the performance of the ESP, and adapt the ESP's operation to changing well conditions.

Abstract: A collection device for use with a drill to capture debris ejected from drilling into a surface includes a body formed of flexible material having a first, substantially flat, configuration and a second erect configuration defining a cavity. The body includes a hole for receiving a drill bit into the cavity when the body is erect and adhesive means for adhering the body to the surface.

Abstract: A collection device for use with a drill to capture debris ejected from drilling into a surface (100) comprising a body (10) formed of flexible material having a first, substantially flat, configuration and a second erect, configuration defining a cavity (120). The body includes a hole (50) for receiving a drill bit into the cavity when the body is erect and adhesive means (80) for adhering the body to the surface (100).
