Definition - What does Mudd Logging mean?
Mud Logging is the process of recording the information of a wellbore by analyzing the rock cuttings brought to the surface by mud. It includes the analysis of the cuttings and recording of information including the detection of hydrocarbon presence and gas analysis. In addition, a Mud Logging unit also monitors and records drilling parameters, mud volumes and flow levels. A portable lab is set up on the rig to carry out the Mud Logging activities.
Petropedia explains Mudd Logging
There are several objectives of Mud Logging such as:
- Identification of economically viable hydrocarbon formations.
- Identification of correlatable geological formations.
- Promoting safe and economically optimized operations by providing data to the driller.
The above objectives can be accomplished by:
- Collecting drill cuttings.
- Conducting lab tests on the minerals present in the cuttings and interpreting the results.
- Determining the rock properties such as porosity and permeability.
- Continuous monitoring of drilling related equipment.
- Estimating the pore pressure of drilled formations.
- Evaluating hydrocarbons released from the drilled formations.
- Assessing the economic viability of hydrocarbon bearing formations and maintaining the drilling parameter records.
