Case Study - South Texas A South Texas operator was faced with a complex multi-stage completion.  Download PDF NuFit
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. Download PDF NuFit
South Texas - Wilcox A South Texas operator was faced with evaluating the completion of a well with multiple Wilcox intervals. Download PDF NuLook
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. Download PDF NuLook
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. Download PDF NuLook
East Texas - Freestone County 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. Download PDF NuLook
East Texas - Limestone County 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. Download PDF NuLook
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. Download PDF NuLook
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. Download PDF NuLook
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. Download PDF NuLook
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. Download PDF NuStim
East Texas Example A NuStim limited entry design allowed for economic completion of an East Texas Cotton Valley interval with a single fracturing stage. Download PDF NuStim
Permian Basin The NuLook process was utilized to identify the source of free water in a New Mexico well with multiple Morrow sands. Download PDF NuStim
Rocky Mountains A Rocky Mountain operator was faced with inconsistent completion results in a field where multiple tight Lewis sands must be economically stimulated. Download PDF NuStim
South Texas - Vicksburg A South Texas operator experienced a problematic completion in the Vicksburg formation. Download PDF NuStim
South Texas - Wilcox 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. Download PDF NuStim Western Oklahoma The NuStim process was utilized to evaluate the completion of a Western Oklahoma Morrow well that was suspected to be under-performing. Download PDF |
