| A unique new product used to cure severe and total loss of circulation in synthetic, oil and water muds. |
| A mixture of inert material and cellulose fiber used to prepare a high solids pill to be squeezed into loss circulation zones. Once in place in a loss zone, the liquid is squeezed out leaving behind a solid plug. |
- Eliminates need to maintain LCM in total mud system.
- Cures lost circulation rather that temporarily reducing losses.
- Eliminates risk of side-tracking such as occurs with cementing.
- Can be acidized if necessary.

- Color: Off white
- Form: Fine Powder
- Specific Gravity: 2.0
- Bulk Density: 12-15 lbs./cu. ft.
- pH: 6-8
- Packaging: 25 lb moisture proof bags
|
- Mix 50-100 bbl pill containing 50-100 bl/bbl of material. Mix in water (oil can be used) and add barite to obtain desired density.
- Squeeze into loss zone and hold pressure for 10-15 minutes.
- Pull up to safe place for 2 hours and resume operation.
|
| Mixing & Spotting Procedure: |
- Calculate hole volume to cover all potential loss zones and mix twice this amount. (Excess slurry is needed for squeeze procedure.)
- Mix in clean tank. (It is recommended that water be used for oil muds; however, oil can be used.) Mix 60 lbs./bbl. Frac Pak with water, then add barite to desired mud weight. Once desired mud weight is obtained, another 20-40 lbs./bbl. of Frac Pak will be added to slurry depending on the weight of the slurry.
- If bit nozzles are 10/32" or larger, it is not necessary to go in open-ended.
- Place bit or open ended drill pipe near the suspected theft zone before pumping squeeze.
- Pump slurry at rate of 3-4 bbls/minute maximum, until bottom of pipe is reached. Stop pumping and fill up back side if not full.
- Close well in and slowly (± 1 bbl/min) pump 3/4 of pill.
- When squeeze pressure reaches 50 psi, stop pumping and hold pressure for 10 minutes. Begin pumping again slowly and if squeeze pressure continues to rise, again stop pumping and hold pressure. Continue this procedure until 200-300 psi squeezed is reached. At this point, open well up and spot the remainder of slurry near theft zone. (Make sure all of slurry is completely out of drill pipe.) Once this has been done, pull up in hole to safe area. Again, shut well in and put 50-100 psi squeeze on formation and hold 3-4 hours. Open well up and circulate there for 30 minutes.
- Run pipe back to bottom slowly. Wash out any bridges and continue operation.
Note: The most important factor determining the success of this squeeze procedure is determining the location of the losses. Precise monitoring of the drill pipe and casing pressures are also important.

| PRODUCT PERFORMANCE REPORT FRAC PAK
DATE: April 26, 2001
PARISH: Lafayette
CASING SIZE: 8.535" ID
CASING SET AT: 13,540’
MUD TYPE: Oil
BIT SIZE: 8.5"
DEPTH: 15,028"
MUD WEIGHT: 16.1 ppg
PROBLEM ENCOUNTERED: Operator lost circulation at 15,028 MD with 16.1 ppg oil base mud. After trying 2 competitors products without success, Boysenblue/Celtec was called for their recommendation. PRODUCT APPLICATION: A 50 bbl slurry containing 80 lbs/bbl Frac Pak and 15 lbs/bbl Blen-Plug was pumped down hole and a balance plug was set. At 14,978 MD, we then pulled up inside the casing and applied 50 psi and held 15 minutes then raised the pressure to 150 psi and held for 15 minutes, finally we brought the pressure up to 200 psi and held for 5 hours. End result 24 hours after Boysenblue was called to location the operator was drilling ahead with no more losses. |

OPERATOR: Prize Operating Company
PARISH: Acadia
WELL: Floyd #1
FIELD: Perry Point
RIG: Grey Wolf 85
CASING SIZE: 9 7/8
CASING SET AT: 13300'
MUD TYPE: Oil
BIT SIZE: 8 1/2
DEPTH: 13990'
MUD WEIGHT: 17.2 ppg
PROBLEM ENCOUNTERED: Operator lost circulation at 13990' with 17.2 oil base mud. Several LCM pills were tried to solve problem without success. Boysenblue/Celtec was then called for their recommendation. PRODUCT APPLICATION: Frac Pak was mixed in a 50 bbl slurry and pumped down hole, then squeezed into theft zone. A total of 35 bbl’s was squeezed into formation at 400 psi. Annulus was then opened and remainder 15 bbl’s was pumped out of drill-string and spotted in open hole. Drill pipe was then pulled up into casing and a 250 psi squeeze was applied against formation and held for 2 hours. RESULTS: Operator then tripped back in hole and washed down last 100' with no losses. Remainder of hole was drilled to T.D. at 15105' with no problems. |
