South Texas - Vicksburg
A South Texas operator was faced with completing
a challenging Vicksburg well in Starr County, Texas. While drilling, hole conditions forced the operator to switch mud systems mid-operation.

East Texas - Carbonate
In this East Texas Cotton Valley B Lime carbonate
section consisting typically of very tight rock, the zones that look cleaner on the GR and SP with very high porosity appear to be wet based on the resistivity profile. Previous
companies would have used these "wet" zones to calculate Rw. These zones may or may not have mud log gas shows while drilling.

East Texas - Core Study
The first two examples, from East Texas Cotton
Valley sands, illustrate the application of NuTech's technology in tight gas sands. The customer in this situation wished to develop a tool that would help identify zones to
stimulate and predict well performance. Historically, the customer's success rate had been below expectations and at high costs.

In this East Texas Cotton Valley sand section
consisting typically of very tight rock, the zones that look cleaner on the GR and SP with very high porosity appear to be wet based on the resistivity profile. Previous
companies would have used these "wet" zones to calculate Rw. These zones may or may not have mud log gas shows while drilling.

Gulf of Mexico - Main Pass
In this Gulf Coast well example this very fine
grain silty and highly laminated formation was found to be normally pressured. This high porosity with fine grain problem typically yields high water saturations and appear to
be mostly water productive.

Gulf of Mexico - Vermillion
In this Gulf of Mexico Vermillion example, the
zone of interest is very fine grained (silty) reservoir with very little character on the 1970's vintage data. The operator was concerned about the low contrast and lack of
character on the older vintage resistivity data over the interval from 12,350 to 12,470 feet. Also, there appears to be a slight convergence on the porosity data, yet no actual cross-over.

Rocky Mountain - Wyoming
In this Rocky Mountain example from Wyoming, the
operator was concerned about quantifying permeability as well as identifying moveable water. Typically the operator would commit to a costly un-focused completion, whereby
perforating and stimulating all zones in the well regardless of their potential.

South Texas - Colorado County
At around 11,000 feet in this South Texas
Wilcox Sand section, it consisted typically of very tight rock that required fracture stimulation. In situations like these, companies are concerned about stimulating a well and
possibly frac'ing into a low resistivity "wet" zone, but these zones may or may not be "wet". This low resistivity could be due to a textural or grain size change. Another issue
a company has to deal with is the salinity of the formation.

East Texas Example
A NuStim limited entry design allowed for
economic completion of an East Texas Cotton Valley interval with a single fracturing stage.

Rocky Mountains
A Rocky Mountain operator was faced with
inconsistent completion results in a field where multiple tight Lewis sands must be economically stimulated.
