A record of geologic materials with depth based on data obtained beneath a point on the land surface and representative of types, depths, and thicknesses of materials beneath that point. The data may represent visual observations, physical/chemical characterizations, and/or geophysical properties. The record also contains information on wells (drinking and monitoring), where appropriate.
Geological, formation attribute, and hydrocarbon potential data obtained with special tools and techniques used downhole.
Well Log - A detailed record obtained during well drilling, correlating with depth information such as changes in electrical resistivity, spontaneous potential, radioactivity, and rock type.
a form completed by a well driller when a well is drilled, and submitted to the Washington State Department of Ecology
a written report showing the property owner, location, and all pertinent information and data relative to the drilling and completion of the well.
a record of one or more subsurface formation measurements as a function of depth in a borehole.
A chart indicating well data such as depth, size of quipment, etc.
A record of geological formation penetrated during drilling, including technical details of the operation.
wireline log, borehole log. The product of a survey operation, also called a survey, consisting of one or more curves. Provides a permanent record of one or more physical measurements as a function of depth in a well bore.
