After collection of data, the next important task is the task of compiling the data into a suitable visual presentation. A log represents data in the form of lines on a lengthy sheet of paper which provides a presentation of relative values of the data obtained.




Mud logging requires the skills of trained well site geologists to collect and analyze cuttings samples, record gas and other hydrocarbon measurements using a full range of qualitative and quantitative analyzers.


When data is collected and logged, it must have an appropriate method of presentation. Mud logs provide information about the geology of the strata in a well for purposes of correlation with other wells in operating oil fields and valuable structural information in wildcat wells.


WELLOG performs mud logging services. 


A mud log combines the hydrocarbon measurement data and a geologic column with depth information in petroleum applications. In mining applications, information on rock types and mineral assay data is presented.


If you need mud log presentation, WELLOG has the software.




Open-hole and cased-hole (production) logs provide two separate types of information at two equally separate points in the life of a well. The open-hole logs present information about the physical rock qualities of the formations encountered in a well. Properties related to resistivity, porosity, density are but a few of the types of measurements that are made.


Cased-hole logs provide information that relates to the production of the well after the production casing has been installed and may or may not include an additional production tubing string.


WELLOG also offers presentation software. Ask about our NEW Well Logging software.

Geophysicists working in the field are responsible for documenting and presentation of data. That data generally is in the form of measurements made on the surface of the earth. Measurements may cover an area of many square miles. Surface data is routinely compiled and presented in the form of a contour map. A contour map resembles a topographic map. Rather than presenting elevation information depicted as contour lines, the presentation is of data contours that represent geophysical highs and lows.


WELLOG has found that a software package called Surfer is an excellent tool for contour mapping.


Surfer can be obtained from Rockware.  Link to Rockware: http://www.rockware.com
