Diversified knows that rocks and hydrocarbon gases matter:
We a vast knowledge of mudloggingoperations and laboratory equipment and bring it to the wellsite.
Can be used alone of as part of your complete laboratory program.
DWL’s Geochemistry services offer critical time sensitive information for unconventional and conventional wells.

Example Well
Total Organic Carbon (TOC) measurement of carbon content present in well cuttings samples. Samples are combusted using the Leco C744 the latest and most advanced carbon determinator for oil and gas applications. The concentration of organic material in source rocks as represented by the weight percent of organic carbon. Samples are powdered, weighed, for two tests TC measures both inorganic and organic carbon, the TOC sample is chemically treated prior to analysis to remove the inorganic carbon (carbonate) from the rock.
For both tests the sample is combusted in the presence of excess oxygen, allowing carbon dioxide to form from the free (organic) carbon in the rock.
The amount of carbon dioxide is directly proportional to the amount of carbon in the rock. The two tests yield Total Carbon (wt%) and Total Organic Carbon (wt%) from these carbonate (wt%) can be calculated.

Improves well placement, drilling and completions
• Best in Class measurements• Rigorous Calibrations against standards are run on
a regular basis• World Class Interpretation expertise
• Experienced staff with over 60 years combined experience
• Experience of staff brings real time relevancy to the data• Mudlogging and geochemical labs background
fused to bring optimized service• Integration with ARM for high resolution rock
collection• Automated Remote Mudlogger can automatically
collect samples at high frequency
The DWL Difference
Traditional Sample Collection & Analysis
Mudlogging Geologist/ Sample CatcherCollects the sample from the Shale Shaker And conducts some preliminary sieving and cleaning
The Mudlogging GeologistWill then make a visual inspection of the Sample under a microscope and make An estimation of the % of each lithology present
Samples are bagged, labeled, shipped then stored

HS & E Risk
One of the key risks Associated with mudloggingIs slips trips & falls. The repetitive nature of Collecting the samples manually, presents a significant risk.
The ROP Challenge
600
Manual Sampling Frequency at 240 ft. / hr. and one sample every 20 minutes – 80 ftresolution
ARM Sampling Frequency at 240 ft. / hr. and one sample every 1 minute – 4 ftresolution
• Higher resolution rock collection and record
• Improved stratigraphic correlation
• Improved understanding of geo-mechanical properties
• Assistance with picking landing zones
• Improved wellbore containment
• Optimized Completions
Qualitative Sample Analysis
The visual inspection and estimationOf the rock composition is qualitative And can vary from logger to logger, day Shift to night shift, well to well.
• ARM* = AUTOMATION
• Industry only fully automated sample collection device
• Sampling triggered by lag calculation via WITS
• Stores up to hold up to 350 samples for later retrieval

• Are the cuttings on depth?
• Do they represent the interval drilled?
• Elemental GR (U+K+Th) vs MWD GR
Excellent Correlation Between Trace Metals Ni and TOC. Discrepancy with V shows need for basin specific calibration.
