FAST~DRILL is a unique water base mud additive that is functionally equivalent to diesel and synthetic oil. It was designed as a liquid for easy product addition, but is 100% active. It is composed of a unique combination of particle protection insulators and anti-sticking agents developed for exceptional performance and complete environmental safety. FAST~DRILL was specifically designed to reduce torque and drag and dramatically improve the coefficient of lubricity. It is extremely effective in this regard and provides a product with multi-functional capability that represents a turning point in drilling fluid technology. FAST~DRILL is a rate of penetration enhancer, torque and drag reduction agent, filtrate loss reducer and shale formation inhibition agent. FAST~DRILL has a L/C 50 greater than 1,000,000 PPM with 6% added to non-toxic mud.
The rate of penetration is primarily governed by mud density, but if your bottom hole assembly is fouled with sticky clay, your ROP will decrease appreciably. Diesel and synthetic oil have been used for years to improve water loss control, slick the hole, and improve rate of penetration. Oil works. We know that. We also know that oil is hazardous to the environment. Synthetic is better than diesel, but the problem remains that while you can hide oil, you cannot make it go away. Even with zero discharge regulation, which is imminent, you must still dispose of the mud and cuttings. If these items are hazardous, and oil is hazardous, your disposal cost escalates rapidly. And, what about accidental spills? Would it be worthwhile to have access to a product that performs like oil, but isn’t?
Water dispersible asphalt became popular when diesel oil was discontinued. An example is Phalt-Seal, which performs the same as an expensive sulfonated asphalt for reducing HT/HP water loss and protecting water sensitive shale formations. However, Phalt-Seal will tend to dissolve in synthetic oil and coalesce. All water dispersible Gilsonite products do the same. FAST~DRILL acts just like oil, but is water dispersible, and completely environmentally safe. Water dispersible asphalt will not coalesce with FAST~DRILL. Clay particles will not swell with FAST~DRILL. Wall cakes will be thinner, harder and less permeable with FAST~DRILL. You will drill faster, cleaner and eliminate differential pipe sticking with FAST~DRILL. Don’t you think this product is worth evaluation?
The most effective poly-glycol for drilling fluids appears to be a PAG. The cloud point for PAG is usually in the range of 150º F to 170º F., and this aspect is touted to be an advantage for shale stabilization. The question is, if PAG is insoluble at that temperature and a production reservoir is at the same location, would you not have reservoir impairment? FAST~DRILL does not have a cloud point, yet it safely protects the clay particle from dispersion and swelling and there is no chance of reservoir impairment. PAG is excellent for inhibition, but it does not always stop swelling of hydratable clay, or prevent gumbo shale from sticking to the bottom hole assembly. FAST~DRILL is as effective as PAG for inhibition, but it also contains ingredients that cleans the BHA, prevents the clay from coming back to stick again and keeps the clay from swelling. If you have a choice, wouldn’t FAST~DRILL be a better alternative?
FAST~DRILL can be added to the mud at anytime. The concentration should be at least 1.5 percent with 3 percent being the maximum needed. If you add oil too fast it will cause the wall cake to strip and clog the flow line. But, you can add FAST~DRILL slow or fast at your convenience. FAST~DRILL will tend to coat the cuttings and dissipate. Maintain your concentration by replenishing on a daily basis. FAST~DRILL performs in all water base-drilling fluids and does not require any complicated maintenance for different systems.
FAST~DRILL is completely environmental safe. It can be land farmed, dumped overboard or spilled with no harmful effects. FAST~DRILL is packaged in poly drums or tote tanks.
- P. Farms 5-X
Brazoria County, Texas
Objective: 15,800’ - Directional “S” Shaped
PHASE 1: 4,600’-12,010 MD
While drilling “S” shaped hole, the Anahuac shale (from ± 6.800’) was left exposed from 8/22/94 to 10/13/94 (45 days) before intermediate pipe was run. The length of time in this interval was due to rig downtime/repairs and loss of drill bit cones in the hole. Before adding FAST~DRILL, tight spots were experienced at 5,738’ and 10,021’ along with increasing drag and sticking tendencies on connections. Torque also steadily increased from ± 420 to ± 500. At this point 1.5% by volume of FAST~DRILL was added to the system. The torque dropped to ± 420 and excess drag and sticking tendencies disappeared. Daily maintenance of FAST~DRILL was needed to keep torque under control. This well was drilled to intermediate pipe depth of 12,010’. After logging, a hole opener run was made and on the last drill down joint, the hole opener became stuck in sand. At this point, 1 drum of FAST~DRILL was immediately pumped down the drill string. As soon as the FAST~DRILL passed around the hole opener, it became free. The hole was circulated clean, an additional 6 drums of FAST~DRILL was spotted in the open hole and casing was run to ± 20 feet off bottom.
PHASE 11: 12,010’-12,875” MD
Hole was drilled to 13,875’ with no problems, with daily additions of FAST~DRILL. Out of 3 other offset wells, this was the only well that the liner was run to bottom. Again, FAST~DRILL was spotted in the open hole before the liner was run.
PHASE 111: 13,875’-15,800’ MD
As of 11/17/94, the well continued to be drilled ahead with no problems. The operator reportedly attributes this success to this product.
Washington County, Texas
Objective: 16,000’ - Horizontal Well
As an active operator in the Austin Caulk, UPRC was experiencing the typical drag that occurs in drilling 16,000’ horizontal wells in Washington County. The drag was up hole in sensitive shale. Lubricant sweeps with other products were attempted the previous day with no success. A competitive product resulted in high viscosity with losses due to blinding of the shaker screen. Also, a glass bead graphite sweep was circulated but the drag remained.
A 60-barrel FAST~DRILL pill was mixed at a 3% concentration in the 13.5-ppg water-base mud and pumped down hole. After the pill cleared the hole section, drag was totally eliminated. Slid drilling operations that had previously been impossible were able to continue.
Pacific Enterprises No. 2
Lafourche Parish, Louisiana
Proposed Total Depth: 14,600
Directional Well–Drilled with PDC bit from 4.630’
Fast drilling rates were seen using the PDC bit until +10,000’ where the drill rate slowed. The rotary could not be turned more than 80 RPM with 8,000-10,000 lbs. of weight on the bit. At this point 1.5% FAST~DRILL was added to the system. The results were immediate, with 110 RPM on the rotary, 10,000-12,000 lbs. Of weigh on the bit, which is the RPM and weight the operator desired and penetration rate increased accordingly.
OCS-G-12014 South Timbalier 33
Proposed Total Depth: 6,991’ MD/5700’ TVD
As drilling proceeded, torque and drag increased while sliding and rotating at 3,700’. Pipe also began to stick. At this point, 2% by volume of FAST~DRILL was added to the entire system. As soon as the well-mixed lubricant was in the system no further problems occurred. The well was successfully drilled to the total depth with no torque or drag evident. Rate of penetration was increased substantially.
Bioassays were taken before and after treatment with FAST~DRILL. The L/C 50 values were not affected and remained above 1,000.000 PPM.
Static sheen tests were performed in the field. No sheen was noted. Drilling fluid pumped overboard did not have any discoloration or sheen.
This case history is positive evidence that FAST~DRILL can be used successfully on any offshore facility with excellent performance and no adverse problems.
A Case History in a Horizontal Drilling Application
Recently, the most active operator drilling in the Austin Chalk horizontal play was confronted with a problem of excessive drag and the inability to slide to correct angle. The Washington County, Texas well was drilling at 16, 820’ MD with a TVD of 14,800’ and had a 13.5-ppg water-base mud in the hole. Several attempts to pump sweeps of other lubricants, including beads and graphite, had been unsuccessful in reducing drag and slide-drilling operations were impossible.
It was recommended that FAST~DRILL be used at 3% concentration for a 60-barrel sweep. Two 55-gallon drums of FAST~DRILL were mixed into 60 barrels of the existing mud. After mixing for 15 minutes it was pumped down hole. An immediate and dramatic reduction in drag was observed. Drag up was reduced from 315K to 265K and slide-drilling operation were now possible. The operator was able to continue slide-drilling operation with no problems. Subsequent slide-drill operations were preceded with similar sweeps of FAST~DRILL pills and all were successful in drag reduction and ensuring the ability to slide without problems.
FAST~DRILL is a product that performs better in the field than in a lab test. However, against competition, FAST~DRILL usually demonstrates superior performance and indicates a reduction on the coefficient of lubricity. Dynamic filtration tests show FAST~DRILL to be 65% to 75% below the dynamic fluid loss of the base.
FAST~DRILL is completely environmentally safe with temperature stability in excess of 350º F. It can be used in the whole mud system, or applied in sweeps for special applications. FAST~DRILL is available in drums or in customer provided tote tanks.
