Abstract: This invention provides a system for detecting flooding in a flexible pipe from a connector of the flexible pipe, comprising: an ROV (3) comprising an arm element (18) designed to move an ultrasound sensor (13), until the ultrasound sensor (13) comes into contact with the connector (14) of the flexible pipe (17); and means for taking ultrasound measurements with respect to the state of the annulus of the flexible pipe (17) from a chamber of the connector of the flexible pipe (17) in contact with the annulus of the flexible pipe (17).

Abstract: A method and system for estimating density of material surrounding a borehole in mineral exploration, the method including inserting a tool into a drilling rod located within a borehole, the tool having a gamma radiation source and at least one sensor; raising the tool within the drilling rod; receiving gamma count readings at the at least one sensor; sending the gamma count readings to a computing device; and removing effects of the drilling rod from the gamma count readings at the computing device to calculate a density of material surrounding the borehole.

Abstract: A calibration site for a gamma-gamma well logging tool for use in mineral exploration, the calibration site having a column consisting of a plurality of blocks of known densities; and a borehole through the column configured to accept the gamma-gamma well logging tool. Further, a method for calibrating a gamma-gamma well logging tool at the calibration site, the method including lowering the gamma-gamma well logging tool into a column consisting of a plurality of blocks of different known densities and having a borehole therein to receive the gamma-gamma well logging tool; raising the gamma-gamma well logging tool at a set rate; capturing a radiation count at a sensor of the gamma-gamma well logging tool; converting the radiation count to a recorded density for a particular depth at a computing device; and comparing the recorded density at each position of the column with the known densities.
