Well Recap
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 31-34 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 continued
--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:
B:
C:
Run MBT every 1000-1500’ of new hole drilled. Maintain a MBT of <10
Run good stream of water at shaker while your drilling, any other water base muds, 15% to
20% dilution
Run shaker screens of 150 to 210 mesh, plus run desander/desilter as long as possible
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.
