Fast computing methods for dual laterolog response of fracture of rigid sandstone reservoir;

Research and application of coal seam log response predicted from seismic attribute;

Study of acoustic log responses to the overpressure formation in the southeast Qiong basin;

Analysis of cased-hole resistivity logging responses;

Review of Continental Sedimentation Logging Response Characteristics;

Then based on computing the minimum of the difference between actual and reconstructed theoretical logging response to obtain the optimum solutions of the geologic parameters,this paper built up a logging interpretation model for igneous .

Monte Carlo numerical simulation of response characteristics of compensated density logging in cased hole;

A theoretical study on detecting depth and spacing of density logging;

The LWD density logging was influenced by several factors such as bore size,stand off between logging tool and borehole wall,mud density,mud cake,cuttings,water cushion and mud invasion.

This article will introduce the application of neutron-density log in Dongpu depression exploration.

Of which,wet basis ash content is defined by gamma-ray log,and the precondition is the ash mainly argillaceous and contains no radioelement;carbon is defined by density log and artificial gamma log,and moisture calibration for density log;saturated porosity is defined by density log after ash calibration;gas content is defined by acoustic log and density log compou.

Cuttings may also be deposited in the bottom of the horizontal hole because of gravity of the earth,and it will have lower density value than the formation, so cuttings beds can have a significant effect on the density log responses.
