Location: Woodville, TX Well name: ETOC T. Hole Total depth: 7300’ Casing 9/58” and 7/78” Mud System: NFS-Super System Water base. Drilled a 12/25” surface hole to 1750’ with conventional gel/water mud. Sat the surface casing 9/58” casing and tested the casing. --Cleaned the mud tanks and filled with freshwater and began additions of NFS-Super System. --Added 10 ppb of NFS-Viscapsule, 1% by volume NFS-Shalecapsule, followed by 1% by volume NFS-Torqcapsule. --Maintained a funnel viscosity and drilled cement with the new mud system. Drilled approximately 120’ cement without any contamination. --Began drilling the 8¾” hole with super system from 1750’ to 2800’. Maintained chemical addition except for NFS-Shalecapsule; at this point mud viscosity was too high. Water was added to the system and the desander/desilter was started. Well Recap

--Drilling stopped and pulled the bit to casing and began to circulate and conditioned mud. Added large volume of water and additions of NFS-Viscapsule, NFS-Shalecapsule and NFS-Torqcapsule; time to condition mud was approximately 4 hours. --Mud was conditioned and resumed drilling operation. Drilling continued at the fast rate of penetration (drilled 1200’ in approximately 12 hours) --Drilled the 8 ¾” to 6500’ and increased mud density to 9.6 ppg from 9.1 ppg using barite. Chemical addition continued to maintain a <6 cc filtrate. --Drilling continued to 7300’ total depth. Circulated bottoms up, made a short trip, back to bottom with no fill. --Pulled the bit out of hole and ran successful logs to bottom, no fill. Ran the casing bottom, no fill. Well Recap continued

Conclusion: NFS-Super System was used successfully to drill this 7300’ well in record time. Total drilling days were reduced by two days, a gage hole was drilled and logged the well successfully. Surface hole from 1750’ to approximately 6500’ had lots of reactive shale and clay, which was encapsulated with the NFS-Super System. While drilling cement, no contamination was observed; in addition the shale shakers handled the flow rate without any gumbo sticking to the screens. Important information to apply for future wells: A: Run MBT every ’ of new hole drilled. Maintain a MBT of <10 B: Run good stream of water at shaker while your drilling, any other water base muds, 15% to 20% dilution C:Run shaker screens of 150 to 210 mesh, plus run desander/desilter as long as possible Well Recap continued

Conclusion This new and revolutionary water based system is now available. NFSI is excited, prepared, and anxiously awaiting to help meet your drilling needs. NFSI currently has finished product available in inventory located in Houston, TX
