UNCONVENTIONAL PLAYS - UNCONVENTIONAL APPROACH
With the continued activity in Unconventional Plays and the deployment of lateral drilling techniques where conventional logging is less successful, the Mud Log is sometimes the only source of relevant down-hole information available.
As a leading provider of seismic data, digital well log data, well performance (production) data, directional survey data and other well related products, TGS is focusing more attention on the incredibly valuable and often overlooked Mud Log. The Mud Log represents a wealth of information gathered at the time of drilling and includes data from the drilling engineer and the well site geologist relating to the rock and hydrocarbons encountered during the drilling process.
In response to industry demand TGS is introducing a number of digital products from the rich and under-utilized Mud Log. Valuable information
can be gleaned from these logs by standardizing the codes and symbols used and applying routine corrections and editing techniques. TGS takes extra measures to provide this more readily useable information.
Standard Mud Log (Mudlas)
The standard MUDLAS product comprises a raster image of the Mud Log, in color where available, plus digitized and QC’d curves captured from the log. Historically these were limited to the ROP, Total Gas and Individual Gas curves (C1, C2, C3 etc.), however, in response to client requests we have expanded the specification to include any other data item on the log that can reasonably be captured as a curve. This includes GR, Shows Data, WOB etc. which are captured and all output into a single LAS v2.0 file. Not only does this ensure that you receive everything available from the log but also in a single file with consistent depth increment and standardized mnemonics.

Mud Lithology And Comments (Mudlith)
Following feed-back from our clients TGS will supply both the Mud Lithology and Comments as a separate product (MUDLITH) upon order. The MUDLITH will provide both the graphical lithology information and more detailed description of the cuttings as well as other pertinent information related to the drilling operation.
Lithology
TGS captures the lithology column from the mud log. Normally each lithology type is represented by a curve expressed as a percentage of the total, however, in some cases the lithology is expressed graphically as individual beds. In either case these data can be digitized and delivered as an LAS v2.0 file.
Comments
TGS will also capture all the cuttings descriptions, remarks and other comments as written on the mud log. Each comment is keyed to a discrete depth and output as a LAS v2.0 file.
