12 Mexico Return North Mexico Mission Field North Mexico Argos Field Mexico North Mexico Mission Field North Mexico Argos Field Operator was drilling at 2963 meters. The drilling rate was approximately 3 Mts. an hour with very high torque, causing the rotary to stall at times. The hole was also very tight on connections. The well was on day 117 and they already had four sidetracks. The angle of the sidetrack was 36.9 degrees. And the flowline temperature was 140 degrees F. hole size was 6" with Mts. Of 7" casing set. The operator had decided to abandon the hole when it was decided as a last resort to add Thuslick™ to the oil mud system. The operator added 6 ppb of Thuslick™ to the mud and torque started to come down as soon as Thuslick™ went around the bit. Drag and torque were reduced and the drilling rate increased to 10 to 15 Mts. A short trip was made at 3142 Mts. And no drag was encountered. Lost circulation was encountered at 3148 Mts. And the mud weight was reduced from a specific gravity of to 1.4 Circulation was reestablished and drilling resumed at 3 to 4 mph, increasing to 7 mph. This rate continued to T.D of 3400 Mts. with no further hole problems. The penetration rate increased over 150% after the addition of Thuslick™. The operator drilled 6" hole to 4100 Mts. and began trying to log. Casing was set at 2670 Mts. and the bottom hole temperature was 175 degrees C. Logs were run to bottom with no problem but drag was so bad coming out of the hole that was impossible to log the well. The Operator added 9 ppb of Thuslick™ to the open hole volume of the drilling mud, and spotted it in the open hole. The drag was eliminated and the well was logged successfully. Central Mexico Drilling at a depth of 5751 Mts. with a polydrill mud system well began experiencing torque running from 460 to 600 amps. This well was being drilled using 4.5" drill pipe with 6" drill collars, and 8 3/8" hole size a decision was made to add Thuslick™ in a concentration of 4.5 ppb. The torque dropped immediately from 450 amps to 200 amps and remained there. The fluid loss dropped from 11cc’s to 6.0 cc’s, and the penetration rate increased 27%. At 18995' the operator decided to core. Coring took place with 450 amps and they cut two and a half meters of core at 18 minutes per meter. The operator was very happy with the increased drilling rate, lower fluid loss, and reduced torque and drag.Return
13 USA BEFORE THUSLICK AFTER THUSLICK Complete Circulation: 7 Hrs At this point 7" casing was set and the oil base mud was changed for water base mud. The well was drilled out with 5-7/8" bit. When the customer decided to use Thuslick™ they were experiencing high torque, drag, low penetration and metal cutting in the mud. They also were making coring runs and had gone to a diamond bid.

14 Mud Company: DowelSubject: Thuslick™ TestLocation: Block 2, AngolaDate: November 30, 1997Operator: Texaco Panama Inc.Well: RAIA 3HAngolaDrilling and sliding continue with the angle building to 77 degrees by the time a bit trip was made at Ft. During this interval, ROP increased to ft/hr with the torque increasing to 500 amps. Toward the end of this interval, ROP dropped back into the ft/hr range with the torque increasing to 550 amps. After the trip, when drilling and sliding resumed at 8834 ft MD, ROP started at 23 ft/hr with 500 amps and gradually increased by ft to 40+ ft/hr with still 500 amps and only 6 to 10 amp fluctuation. At this point the angle was approximately 80 degrees and building. Overall the penetration rate was excellent and torque leveled off at around 500 amps. Drilling continued to where a 7" liner was run with no problem. The hole angle was 90 degrees at this point. The 7" liner was drilled out with a 6" bit and 3-1/2" drill pipe. Drilling and sliding continued over the next 500 ft at an average penetration rate of 17 ft/hr with 440 to 450 amps. Drilling of the horizontal section is continuing at this time at a depth of 12,700 ft with 470 amps and no problems. Report written by Jim Saxon - Mud EngineerThuslick™ was added initially at the amount of 4 ppb over one circulation. After one circulation measured depth was 8922 ft. and the hole angle was 47 degrees.The average rate of penetration BEFORE Thuslick™ was added was 18 ft / hr and the torque was 450 to 475 amps. AFTER the addition of Thuslick™, sliding started at a rate of ft / hr with 450 amps.Return

Short trips were made from 7154 ft to 4480 ft with drag of 30 to 40 Klbs and, from 9981 ft to 6969 ft we did not encounter any problems. From 11,980 ft to 10,105 ft with drags of 40 to 60 Klbs, from 13,975 ft to 11,396 ft Pipe was pulled free with pump and rotation from 13,066 to 11,424 ft. The concentration of Thuslick™ was increased from 4 to 5 ppb to solve the drag problem. The 12 1/4" hole was TD at 14,720 ft. Caliper log was run to 11,950 ft. without any problems. 9-5/8 casing was run without problems.Due to problems such as drag, high torque, bit balling and low ROP in the 12- 1/4" section in the Ceuta Field Block VII, Area 8, and the elimination of the use of the VASSA LP-90 Mineral Oil from the formulation because of environmental concerns, MI and Foramer de Venezuela (Pride) decided to use the product called Thuslick™ in conjunction with the liquid lubricants (VEN-LUBE + LUBE 100) in the 12 1/4 phase of the VLG-3854 and VLG All problems previously exposed were reduced utilizing a concentration between 4 and 5 ppb of Thuslick™ and 1.7% to 2.28% (6-8 ppb) of the liquid lubricants in the system.1.65Caustic Soda4.00Thuslick™3.86Ven Lube0.826Lime0.09XCD1.89Ventrol0.10Mix II0.70Lube 1672.35CaCo33.14Lube 1000.60Dril Kleen1.40SP 1010.54Pac R4.45Asphasol3.13Tannathin7.72Spercene4.31Gel143.69BariteConcentration PPBProductsReturn
16 DenmarkOperator was drilling a horizontal section in a North Sea development project. With about 300 meters of horizontal hole drilled, the operator began to experience severe drag and torque, and metal shavings appeared in the cuttings. Thuslick™ was added to the water based mud system at this point. Torque came down immediately, and stabilized at a figure 15 Kft.lbs. for the rest of the well. Metal shavings disappeared at once and the cuttings have remained free of metal shavings since. The well was drilled to T.D. (and additional 1600 meters) without further problems.The operator was very pleased with the performance, and has included Thuslick™ in future mud programs for the development program.Return
17 ArgentinaOperator was drilling an extended reach well offshore to onshore in Tierra del Fuego.The well was drilled to 1800 Mts. where the curve was built to 90 Degrees. Drilling continue to 5580 Mts. where 9-5/8" casing was run and cemented.The casing shoe was drilled and Thuslick™ was added to the mud to relief torque problems.The concentration of Thuslick™ was 4.8 ppb.BEFORE adding Thuslick™ the operator was sliding at a rate of 5 to 10 Mts. per Hour. AFTER adding Thuslick™ the sliding rate increased to 18 to 20 Mts. per Hour with a bit weight of 5 to pounds. The normal coefficient of friction in the area is .20 to .25 with the addition of Thuslick™, the coefficient of friction was reduced to .13 to The operator felt that Thuslick™ was very successful in this application.Rotary drilling resumed, and the Thuslick™ increased to 5.5 ppb. Drilling rates were 66 Mts. Per Hour with a torque 25 to 28 thousand foot pounds. The well was drilled to T.D. at 6450 Mts. The final angle of this well was 91 Degrees.Return
18 Subject: Thuslick™ Test Location: North Sea - Eldfisk AlphaDate: 10/11/2000Operator: Phillips Petroleum Co.Well: 2/7A-22NorwayIt is beyond any doubt, that Thuslick™ was extremely efficient in this application, and it may well have been one of the main contributors in TDing the well as per plan. When drilling 8.5" section on Eldfisk Alpha well no. A-22 excessive drag and torque were experienced. This caused severe directional problems as steering and sliding became more and more difficult. Thuslick™ was added twice in 50 bbl pills with 4 PPB concentration, but with little or no improvement in sliding. When pills returned to surface we found that Thuslick™ plugged the screens. On the VSM 300 shakers we were running 240 as bottom screens to take out the majority of drilled chalk form the mud to keep mud weight as low as possible. As the pill of Thuslick™ returned screens were plugged and we had to change to 120 mesh screens to avoid losses. As a total of 400 lbs Thuslick™ was added to a circulation system of 1000 bbl it was not really expected to see any positive effect from these two Thuslick™ pills. A couple of days later severe losses were encountered and we could not keep up with mixing mud. As reservoir pressure is extremely low form depletion, an inexpensive mud of drill water with polymer normally used. Due to severe mud losses, we now changed to seawater only, without any additives. Losses leveled off at 200bbl/hr. while circulation at a rate of 800 bbl/hr. Now high and erratic torque was experienced, and Thuslick was added to the seawater. CONCLUSION: Conclusions drawn from using Thuslick™ when drilling 8.5" chalk reservoir section was very positive and contributed greatly in completing the section as planned.Positive findings: Adding Thuslick™ had an immediate effect on drilling parameters. Torque was significantly reduced an made it possible to continue drilling to target. The reduced torque also resulted in increased ROP (Rate of Penetration), with less WOB (Weight on Bit). Even when we stopped adding Thuslick™ for some time, the torque remained low, indicating that Thuslick™ had successfully added a lasting coating in the well bore and casing.Return
