The first total drilling fluid in a single sack.
Environmentally Friendly Whole in One
Description Whole in One is a blend of anionic and nonionic polymers, fibers, and minerals for a complete high performance water-based drilling fluid system that is specially formulated to drill lateral and directional wells and can tolerate contamination and provide excellent lubricity and shale inhibition.
Advantages The stability, speed and performance of an oil-based fluid system Overall well bore integrity by minimizing shale problems and hole enlargement Penetrates and seals micro fractures Minimizes mud losses Resistance to chemical contamination Provides lubricity and reduces metal to metal contact Excellent Hole Cleaning Can be re-used but there are no disposal problems (passed microtox EC 50 Bioassay) LC 50 Reduce health, safety and environmental harm to rig personnel Lower costs due to clean up, disposal and transportation of oil based cuttings
Economics Significantly lower total cost per barrel No environmental clean-up cost No cuttings transportation cost Lower transportation cost Availability of fresh or seawater as base fluid Low maintenance cost Reduced inventory cost on location by 75%
Mixing Procedure Whole in One can be mixed in any type of available water on location; i.e. fresh, saturated salt, drill or seawater Fill the pits with the desired volume of water Mix 7.0 ppb Whole in One through the mud hopper Agitate the pits for 30 minutes Continue to shear the mud through the hopper until the funnel viscosity is 33 sec/qt or more Add the weighting agent to the desired mud weight The fluid is now ready for displacement
Daily Maintenance Keep the mud hydrated Maintain 7.0 ppb Whole in One Track dilution and volumes
Shale Erosion Test of Whole in One Before Shale ExposureAfter Hot Roll and Drying Sample from Arkansas
LC 50 Results
Packaging Whole in One is available in two sizes: 25 lb. paper sacks 2000 lb. super sacks
Performance Profile Case History #1 - Terryville Field, Haynesville Lateral, Lincoln Parish, LA The surface hole was drilled to a depth of 1,878’ where the pits were mudded up with Whole in One and the well was drilled to intermediate casing depth at 9,490’ with no problems. The curve was built and the lateral section was drilled with Whole in One (replace conventional oil base mud) to 16,025’ with a 13.8 ppg mud weight. The casing got stuck and the hole was sidetracked at 10,129’ with a 12.0 ppg mud weight. The lateral was re-drilled using the same system, sweeps, etc. with a maximum mud weight of 15.8 ppg. Case History #2 - Terryville Field, Haynesville Lateral, Lincoln Parish, LA The surface hole was drilled to a depth of 1,872’ where the pits were mudded up with Whole in One. Anhydrite was drilled at 4,452’ with no problems. Picked up directional tools at 4,826’, drilled to 9,270’ and had to weight up to 10.8 ppg due to splintery shale. Drilled to 11,273’ with Whole in One and set intermediate casing. Built the curve and drilled the lateral section with Whole in One (replaced conventional oil base mud) to 15,884’ with no problems. Case History #3 - Terryville Field, Haynesville Lateral, Lincoln Parish, LA The surface hole was drilled and casing set with no problems. The pits were mudded up with Whole in One and drilling resumed. Anhydrite was drilled at 5,276’ with no change in mud properties. Built the curve using Whole in One, drilled to 11,487’ and ran intermediate casing with no problems. Drilled to total depth at 15,404’ with Whole in One (replaced conventional oil base mud), ran production casing and cemented with no problems.
Performance Profile Case History #4 - Webb Co., TX, Eagle Ford Latera l The surface hole was drilled to a depth of 3,520’ where the pits were mudded up with Whole in One. The hole was drilled to 14,493’ and while pulling out of the hole the pipe got stuck at 13,602’. TIH with whip stock and side- tracked the well with oil base mud. The problem wasn’t using Whole in One, because after displacing with oil base mud they had to do a second side-track and eventually plug and abandoned the well due to frac sand communication from another well. Case History #5 - South Texas Eagle Ford Lateral The surface hole was drilled to a depth of 2,160’. Drilled to 7,536’ where the pits were mudded up with Whole in One. Drilled to 10,140’ and set intermediate casing with no problems. Cored from 10,140’ to 13,843’ with Whole in One and started building the curve at 11,300’ and finished it at 12,945’. Drilled the extended reach lateral with Whole in One (replaced conventional oil base mud) to TD at 17,250’.
Conclusion This new and revolutionary single sack water based system is now available. NFSI is excited, prepared, and anxiously awaiting to help meet your drilling fluid needs For any additional information please contact: Joe Morris
