G&G Applications

G&G Applications Course

VIDL Network experience can introduce you to Geological & Geophysical (G&G) Applications, or more specifically, geologic and geophysical modeling. Geological modelling or Geomodelling is the applied science of creating computerized representations of portions of the Earth’s crust based on geophysical and geological observations made on and below the Earth surface. A Geomodel is the numerical equivalent of a three-dimensional geological map complemented by a description of physical quantities in the domain of interest. Geomodelling is related to the concept of Shared Earth Model; which is a multidisciplinary, interoperable and updatable knowledge base about the subsurface.

Guide Project GG 502


Lithostratigraphic Correlation   For this project you will make a fence diagram of the Late Cretaceous Strata of the Denver-Julesberg Basin. You will do this by interpreting well logs from wells drilled for oil and gas production in the Basin.  The relative locations of the wells are mapped on the accompanying Project Well Location Map. The Well Log is a Bore Hole Image [...]

Guide: GA 101 – Structural Styles – Compressional


Module GA 101 concentrates on the tectonics and propagation of thrusts such as the Andean style & Himalayan style. Structural terms are set forth; describing the orientation of fold limbs, circular outcrop patterns typical for both domes and basins, and monoclines the result of movement along buried faults. The module covers the basic fault concepts, recognizing detachments, and complex geometries. The strike slip faults are [...]

Guide: GA 102 – Structural Styles – Extensional


Module GA 102 concentrates on the tectonics and propagation of contacts and unconformities. Structural styles of the normal fault concept are covered. The conformable and intrusive contacts are described. Throughout the one hour video, surface and seismic examples are discussed. This module is for someone who has interest in a geologic review of terms and structural styles or for the individual seeking an understanding of [...]

Guide: GA 103 – Sequence Stratigraphy


Module GA 103 concentrates on sequence stratigraphy models and interpretation. Unconformable relations in the sedimentary strata are critical for determining timing and events. It is important in interpretation to recognize clastic facies seismic patterns. Various models as related to geologic and seismic patterns are discussed. The seismic interpretation technique is outlined with examples. This one hour video module is for someone who has interest in [...]

Guide: GA 201 Seismic Well Tie


Introduction Well tie is a necessary step in seismic interpretation. It is done to ground truth seismic data; to extract a wavelet for seismic inversion, synthetic modeling, or seismic calibration. Seismic amplitude calibration to true amplitude is required before any amplitude analysis and interpretation such as AVO. Well tie is key in accurate seismic interpretation especially if interpretation is for well placement. One sample error [...]

Guide: GA 202 Borehole Seismic Surveys and Applications


Surface seismic data is the most used data type in hydrocarbon exploration and development. Yet, it has some major shortcomings. These shortcomings stem from the requirement that during data acquisition, the sources and receivers are always positioned at or close to the surface. This requirement imposes major limitations on the acquired surface seismic data. The above limitations can be addressed by properly designed borehole seismic [...]

Guide: GG 101


Well Logs Basics   The Well Log is a Bore Hole Image. It is record of a continuous in-situ down hole measurement of the physical and structural properties of a penetrated formation. Modern day technology in oil/gas/mineral exploration utilizes a variety of probes (instruments) either singularly or in combination (stacked). Each of these well log types is utilized based on the objective selected [...]
