 <xsd:documentation> WITSML - Lithology Component Schema. The standard for this version is principally intended for the implementation of the graphical columns for lithology and anticipates the use of a free text entry for the description. It is possible in the future the standard may be used to generate a structured text description from discrete entries and so some of terminology has been better defined to enable that useage. Either the free text description should be used, or structured description, but not both.</xsd:documentation>

-<xsd:annotation>
 <xsd:documentation>A custom Lithology encoding sceme if desired. (It is recommended that if used, this follows the NPD required useage with the numeric values noted in the enum tables, which was the original intent for this item). The NPD Coding System assigned a digital code to the main lithologies as per the Norwegian Blue Book data standards. The code was then derived by Lithology = (Main lithology * 10) + cement + (modifier / 100). Example: Calcite cemented silty micaceous sandstone: ( 33 * 10 ) + 1 + (21 / 100) gives a numeric code of 331.21. However the NPD is also working through Energistics/Ceasar to potentially change this useage.) This should not be used for mnemonics, as those vary by operator, and if an abbreviation is required a local look up table should be used by the rendering client, based on Lithology Type.</xsd:documentation>

 <xsd:documentation>The lithology represents the portion of the sampled interval this lithology type relates to. The total of the lithologies within an interval should add up to 100 percent. If LithologySource in cs-geology is "interpreted" only 100% is allowed. If "core" or "cuttings" then recommended useage is the creating application uses blocks of 10%. i.e. 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. Ideally the input application should enforce a total of 100% for every defined depth interval. If the total for a depth interval does not add up to 100%, the "undifferentiated" code should be used to fill out to 100%. </xsd:documentation>

-<xsd:annotation>
 <xsd:documentation>A single qualifier from the Qualifier enum table for graphical representation in the Lithology columns. In mudlogging terms, a qualifier is a graphical symbol in the Interpreted Lithology column of the Formation Evaluation Log (aka "the mudlog"). In addition to the major lithologies (e.g., sand, shale, etc) existing in the sample, other minerals (present as accessories or inclusions e.g. chert, pyrite, glauconite) and fossils (forams, oyster shells, bryozoans, etc.) may exist and their abundance is generally categorized using ranges such as Trace. These additional minerals and fossils can be of disproportionately great diagnostic and descriptive value. For example,qualifiers can be used to indicate facies changes, marker beds or something that impacted drilling conditions. These qualifiers (representing accessories, inclusions and/or fossils) are used to rapidly and graphically indicate to the recipient of the mudlog that a significant lithological event was encountered while drilling the well. The qualifier can also be used in creating the structured descriptions. </xsd:documentation>
