Mudlog data content

• Approximately 175 types of information

• Gas Hydrocarbon Data
• hydrocarbon shows staining, fluorescence, cut
• total gas, gas chromatograph analysis (component
  concentrations), gas ratios
• H2S CO2

• Mud Data
• composition, volume,
• temp, resistivity, mud wt (in/out)

• Drilling Operation Data
• hole depth, ROP
• bit info bit trips, type, no.,WOB, RPM
• drilling parameter changes, drilling rate
  exponent
• pump pressure, mud rate, mud pump stroke counts
• coring points, DST, LOT
• MWD / LWD

• Cuttings Lithologic Data
• lith description rock type, color, texture etc.,
  visual porosity
• interpreted log and lithology percentage log

Project Status

• Mudlog extensions approved by Technical Committee
• WITSML release 1.3 to incorporate mudlog
  extensions
• Expected release date 31 Jan 2005
• Evaluate use of mudlog object for other purposes
  such as Geological Report.
• First phase pilot started by ExxonMobil

Mudlog Object Demonstration

• Using GEO Sitecom

12
Use of Mudlog object in GEO
Start Wizard
Connect to Server
Select Well/Wellbore/Data to load
Select curves to load
Map lithology names
Finish!
The mudlog is created by loading log and mudlog
objects directly from a remote WITSML server.
