Slide 5: Baroid's Solution
Baroid’s SOLUTION N-SQUEEZETM lost circulation material is a non-damaging cross- linkable water soluble polymer that helps cure lost circulation in many different applications. N-PLEXTM cross-linker contains a retarding agent to achieve a crosslinking time of approximately 2-4 hours, allowing time t
Slide 6: Applications
Applications N-SQUEEZE / N-PLEX Lost Circulation Material Applications: Helps cure lost circulation in vugular or fractured formations Temporary plug to run in front of cement squeezes Improve casing shoe integrity Seal unconsolidated formations © 2012 HALLIBURTON. ALL RIGHTS RESERVED. 6
Slide 7: Features
key FEATURES Acid soluble Single sack product Adjustable, time-delayed cross-linking capabilities Biodegradable, non- damaging to production zones © 2012 HALLIBURTON. ALL RIGHTS RESERVED. 7
Slide 8: N-SQUEEZE / N-PLEX Data
N-SQUEEZE / N-PLEX Data Reaction is a pH/temperature dependent mechanism Higher temperatures require a higher pH for cross-linking The figure above depicts the relationship of concentration of available cross-linking agent with pH and temperature in 5% KCl brine. © 2012 HALLIBURTON. ALL RIGHTS R
Slide 9: N-SQUEEZE / N-PLEX Data
N-SQUEEZE / N-PLEX Data Must be pH-balanced to set the conditions for the optimal cross-linking at a given temperature. Can be tuned to react and thermally degrade at desired rates based on temperature by altering the concentration of cross-linker in the formula. © 2012 HALLIBURTON. ALL RIGHTS R
