Borehole compensated density logs corrected for naturally occurring gamma rays.
The underlying reason for the better accuracy of the density log is that density, unlike radioactivity, is an inherent property of organic matter (Schmoker, 1981).
S]) and density logs were displayed and analysed in the well-viewer of the RokDoc project (figure 3).
5, 1498 m and 1508 m), and the mud transgression drives the density log value of the undisturbed formation much lower than the normal mudstone.
During the twentieth century over seventy wells were drilled in the area penetrating through the targeted coal section, as established by drillers' logs, electric logs and density logs.
Shell was able to define the gas oil contact for the Cornea Field from sonic and density logs.
The neutron density logs had cross-over gas within the zones and filter cake is formed throughout these pay zones.
Doing so will enable the Company to pool resources from prior sonic and density logs to construct a better understanding of the surrounding area with the aid of a 3 dimensional perspective furthering our confidence of known structural traps and anomalies in the area.
This will enable Pemberton to tie in different attributes of sonic and density logs to the surrounding area in a 3 dimensional view, giving confidence in structural traps and anomalies and determine if there is closure.
