WaterWeb Service

APPLICATIONS WaterWeb offers a range of relative permeability modifier (RPM) polymers depending on the permeability range of the reservoir. This service is ideal for use in wells that have: » Permeability greater than 0.1 mD and less than 8000 mD » Bottomhole temperatures of up to 325°F (163°C) » Multi-layered formation without crossflow within the reservoir » RPM formulation optimized for different lithologies, including sandstones and calcite-rich formations BENEFITS » Reduce water production » Increase hydrocarbon production » Reduce costs associated with produced water » Extend the economic producing life of the well » Increase recoverable reserves OVERVIEW Halliburton WaterWeb service uses unique polymer chemistry to selectively reduce water effective permeability in the reservoir, helping impede water flow and enhancing hydrocarbon flow to the wellbore. With WaterWeb, the resulting improved oil/gas recovery potential stems from a reduced water column giving improved natural lift for the residual oil and/or gas. In addition, it helps prolong and sustain production by enhancing reservoir drainage. WaterWeb is applicable to sandstone and carbonate lithologies. WaterWeb works by adsorbing onto the rock surface, reducing effective permeability to water by more than 90 percent with little to no damage to hydrocarbon permeability. In effect, WaterWeb creates resistance that holds back water while allowing oil and gas to pass freely. WaterWeb ® Service SELECTIVELY REDUCING WATER PRODUCTION FOR IMPROVED PRODUCTION PROFILES AND WELL LIFE EXTENSION WaterWeb polymer adsorbs to the rock surface, selectively decreasing effective water permeability with little to no damage to hydrocarbon flow. The above graph shows the response of an oil saturated core and a water saturated core before and after treatment with WaterWeb service. In this case, the effective permeability of the water saturated core was significantly decreased while the effective permeability in the oil saturated core was minimally impacted. Both permeabilities were measured at residual oil and water saturations, respectively. LEVEL 1 CAPABILITY | Level 2 Capability (if applicable) WELL INTERVENTION | Custom Chemistry
