NFS-Super Squeeze™ “The Hole-In-One” Process

Description NFS-Super Squeeze™ Process is a dewatering system that can be applied directly into the well bore to create a strong bridge. A broad PSD range can assist reducing or eliminating major mud losses by filling all vugular and cavernous formations. This unique process can be applied with open ended or bypass sub. NFS-Super Squeeze™ can cure mud losses instantly without time or temperature dependency.

Advantages Single sack systemEasy mixing No spacer required No setting time required

Benefits Mixes in all types of fluids Environmentally acceptable; complies with all LC 50 requirements Contaminant friendly Temperature stable up to 400°F

Physical Properties Appearance:Powder Color:Brick Red Specific Gravity:1.89

Packaging: NFS-Super Squeeze™ is packaged in 25 lb paper sacks or 2000 lb super sacks.

Mixing Recommendations 25 barrel increments (in fresh or salt water, diesel, or base oil): In a clean mixing tank, prepare 25 barrels of fluid, then mix 90 bags (90 ppb) of NFS- Super Squeeze™ through the mud hopper, add Barite for desired density

Placement: Prepare the NFS-Super Squeeze™ slurry in a clean tank. Simply pull one stand or pull to the last casing shoe to avoid stuck pipe. Pump ahead with the rig pumps. Pump through the bypass sub or through an open ended drill string. Close the Hydril, perform a gentle squeeze ( psi). Hold for 30 minutes. Open Hydril. Break circulation.

Additional Technical Information: NFS-Super Squeeze™ has a broad PSD range to address sealing and bridging of large-fractures and cavernous formations. Discharged water which is squeezed from the slurry will have a significant chemical reaction from the polymer technology in the mixture. Once into the formation the fluid discharged will bond with any clay or gumbo shale to form a cement like bridge inside the fracture. After the water is discharged into the formation, a solid bridge will form at the tip of the fracture Dewatered plug has a compressive strength of >4000 psi

Laboratory Testing/ Results: Prepared 350 cc slurry with 90 grams of NFS-Super Squeeze™ placed in a PPT device with a 190 micron disk then squeeze filtrate out with 100 psi pressure. Placed 17.0 ppg oil base mud on top of the disk then pressured to 1000 psi Results: Held 1000 psi pressure for 30 minutes with zero spurt loss and zero filtrate, thus NFS-Super Squeeze™ plug was solid and no fluid could penetrate through the disk

Laboratory Testing/ Results: A PPT results 200 psi at 5 minutes= 6ml B PPT results 400 psi at 5 minutes= 4ml C PPT results 600 psi at 5 minutes= 3ml D PPT results 800 psi at 5 minutes= 1ml E PPT results 1000 psi at 5 minutes= 0 ml

Laboratory Testing/ Results: Compression testing: Prepared a plug by squeezing 90 ppb of NFS-Super Squeeze™. Placed the plug under the cement compression testing device model RF- T15 according to ASTM 1633 Test Procedure and applied gradual pressure on the plug. ( Unlike Cement no WOC ) it hardens instantly. Resulted in 4000 psi which flattened the cake without crumbling as demonstrated in the pictures below. Pressure psi results = 4000 psi

Laboratory Testing/ Results: NFS-Super Squeeze™ Before Compression Test NFS-Super Squeeze™ After Compression Test 4000 psi * formed plug before applied pressure* After applying 4000 psi was flattened but not crumbled, thus showing real compressive and tensile strength ASTM 1633 Test Procedure
