NuLook Success StoriesIn 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.
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 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.
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.
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.
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.
A West Texas operator approached NuTech to diagnose marginal results from a nine stage Wolfcamp completion in the Permian Basin. In an effort to address client needs in multi-stage vertical completions, NuTech’s stimulation design team (NuStimTM stimulation vision) produced a fracture cluster montage that clearly shows each stage and the corresponding fracture effectiveness by demonstrating not only the fracture geometries, but the economic returns as well. A positive NPV completion strategy was implemented on future completions coupled with fewer frac stages as a better assessment of rock properties and permeability from NuTech’s advanced petrophysical analysis (NuLookTM Shale Vision) was implemented. The result yielded a greater definition of the reservoir variability and an optimized completion strategy that reduced upfront CAPEX by eliminating 3 frac stages.
A NuStim limited entry design allowed for economic completion of an East Texas Cotton Valley interval with a single fracturing stage.
The NuLook process was utilized to identify the source of free water in a New Mexico well with multiple Morrow sands.
A Rocky Mountain operator was faced with inconsistent completion results in a field where multiple tight Lewis sands must be economically stimulated.
A South Texas operator experienced a problematic completion in the Vicksburg formation.
The NuStim model was calibrated for this area based on existing completion data for an offset South Texas Wilcox well, which was completed with a massive multistage hydraulic fracture treatment.
The NuStim process was utilized to evaluate the completion of a Western Oklahoma Morrow well that was suspected to be under-performing.
NuFit Success StoriesA South Texas operator was faced with a complex multi-stage completion.
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.
A South Texas operator was faced with evaluating the completion of a well with multiple Wilcox intervals.
An operator utilized NuTech Energy Alliance’s NuLook and NuFIT analyses in order to characterize the sands and predict performance prior to fracturing.
