Abstract: A system and method of analysing drilling cuttings using image data output from a hyperspectral imaging device and at least one optical camera, includes generating a hyperspectral imaging data set including a plurality of lines of hyperspectral data derived from line images taken by the hyperspectral imaging device positioned along a drilling fluid cuttings path, obtaining tracking information in respect of particles of interest from the output of the at least one optical camera, correcting the position of pixels associated with particles of interest in the plurality of lines of hyperspectral imaging data based on the obtained tracking information to generate corrected hyperspectral imaging data, and analysing the corrected hyperspectral imaging data to characterise the cuttings.

Abstract: A method of measuring the viscosity of cement slurry used for a primary cementing of an oil or gas well includes pumping the cement slurry along a conduit to a cementing location, measuring a first pressure loss along a first, horizontal portion of the conduit and a second pressure loss along a second, vertical portion of the conduit, and calculating a viscosity of the cement slurry based at least in part on the first and second pressure losses and a flow rate of the cement slurry.

Abstract: A method and system for calculating the viscosity of cement slurry used for a primary cementing of an oil or gas well (12) comprises: pumping the cement slurry along a conduit (16) to a cementing location (20); measuring a first pressure loss along a first, horizontal portion (28) of the conduit (16) and a second pressure loss along a second, vertical portion (30) of the conduit (16); and calculating a viscosity of the cement slurry based at least in part on the first and second pressure losses and a flow rate of the cement slurry.
