| Information Provided by Technique | |
| Lithology: | Identify lithology and mineralization, provide core samples and rock cuttings |
| Stratigraphic/Structural: | Retrieved samples can be used to identify stratigraphy and structural features such as fracture networks or faults |
| Hydrological: | -Water samples can be used for geochemical analysis
-Fluid pressures can be used to estimate flow rates |
| Thermal: | -Temperatures can be measured within the hole
-Thermal conductivity measurements can be done on retrieved samples. |
Drilling Techniques:
There are a variety of drilling techniques which can be used to sink a borehole into the ground. Each has its advantages and disadvantages, in terms of the depth to which it can drill, the type of sample returned, the costs involved and penetration rates achieved. There are two basic types of drills: drills which produce rock chips, and drills which produce core samples.
The given value was not understood.
Drilling normally begins with small diameter shallow wells such as Thermal Gradient Holes, Slim Holes, or Core Holes. Once data are gathered from the more inexpensive drilling methods a better reservoir model can be made and then locations for further drilling can be narrowed down. Once a confident reservoir model is made Development Drilling methods can be employed.
