1. FinesWedge™ Conductivity EnhancerImprove Long-Term Production Rates by Inhibiting Fines and Scale Damage in Proppant Packs

2. Challenge: Unconventional/Offshore - Sandstone Fines ControlSolution: FinesWedge™ Conductivity Enhancer Surface modification agent that can: • minimize the invasion and inhibit the migration of formation fines into the proppant pack • increase porosity and permeability in the proppant pack through better vertical distribution, leading to higher conductivity and increased production • inhibit scale formation in treated proppant packs, preventing flow restriction and corrosion • provide improved HSE performance and reliability. Non tacky material can enable efficient pumping operations and clean up

3. Fines Control Fines catching performance: • Comparison between treated and non-treated proppant samples with various fines Silica fines Carbonate fines Coal fines

4. Enhanced Proppant Distribution The increase in volume (by 25%) of the coated sand can result in higher downhole conductivity endurance Non-treated sand Sand treated with FinesWedge agent

5. Cyclical Stress Endurance Silica flour was used in simulating the unconsolidated formation. Carbo-Lite 20/40 Mesh™ proppant was used at a loading of 5 lb/ft2. Results indicate that the treatment effectively stabilized the unconsolidated fines and resulted in up to a 22 fold conductivity performance improvement for treated proppant relative to control.

6. Packed layers after removal from each conductivity cell; (left) untreated proppant; (right) proppant treated with FinesWedge enhancer. Amount of silica fines produced in the effluents of conductivity cells that have been treated with FinesWedge enhancer or without treatment.

7. Scale Inhibition Proppant without FinesWedge agent Proppant with FinesWedge agent

8. Where will it work? • Can be highly effective both in hard rock and in unconsolidated formations, on-shore and off-shore • Primary and remedial applications • Applicable for BHST 75°F (24°C) to 350°F (177°C) • Versatile – compatible with wide variety of proppants and all Halliburton fluid systems. • High salt and temperature tolerance

9. FinesWedge Agent Summary of Benefits • Surface Benefits • Non-tacky to the equipment • More uniform coating • Dry-coat or wet-coat • Less viscous-easier to pump • Pumpable with surface temperatures -20°F (-29°C) to 140°F (60°C) • Compatible with Halliburton services • Downhole Benefits • Scale inhibition in proppant pack • Higher initial conductivity • Higher conductivity endurance • Fines immobilization • Higher long term production • Aids in fluid residue cleanup • Passed all GOM HSE requirements • High salt and temperature tolerance • SPE-169802-MS Maintaining Production of Frac-Packed Wells by Inhibiting Scale Buildup and Fines Migration • http://www.halliburton.com/public/pe/contents/Data_Sheets/web/H/H011055.pdf
