Density logging while drilling
WebDensity logging is a well logging tool that can provide a continuous record of a formation's bulk density along the length of a borehole.In geology, bulk density is a function of the density of the minerals forming a rock (i.e. matrix) and the fluid enclosed in the pore spaces.This is one of three well logging tools that are commonly used to calculate … WebGyro While Drilling (GWD) surveying.

WebThe density log-derived porosities in logging Units 1-3 (0-180 mbsf) of Hole 1246A range from ~40% to 80% (Fig. F30 ). The LWD neutron porosity log from Hole 1246A (Fig. F30) yielded sediment porosities ranging from an average value at the top of the logged section of ~70% to ~60% in logging Unit 3. The tool itself initially consisted of a radioactive source and a single detector, but this configuration is susceptible to the effects of the drilling fluid. In a similar way to how the sonic logging tool was improved to compensate for borehole effects, density logging now conventionally uses 2 or more detectors. In a 2 detector configuration, the short-spaced detector has a much shallower depth of investigation than the long-spaced detector so it is used to measure the effect that the drilling flu…
