Figure A - wellbore schematic and PLT before WaterWeb service treatment. EASY TO USE AND FIELD PROVEN WaterWeb service requires no special placement techniques. It is unaffected by multivalent cations, oxygen, or acids. It does not require rig time or zonal isolation. WaterWeb service works by immediately adsorbing to the rock matrix as it is being pumped (it does not gel or “set up”), so the wellbore can immediately be brought back to production after the treatment. No shut-in time is required. To date, Halliburton RPM chemistry has been used in more than 3,000 wells around the world with excellent results. CASE HISTROY A cased-hole and perforated well producing from an onshore laminated sandstone oil reservoirwas completed in 15 different zones (681 ft gross interval, 155 ft of net perforations) with the following properties: 20°API oil, average permeability ~195- md, average porosity ~13 percent, and BHT~280°F. Water production had been a major challenge in this reservoir, limiting the economic life of many wellbores. Production rates for the well before WaterWeb service were reported as 1200-BFPD, 260-BOPD, 960-BWPD, and 80 percent water cut. Figure A shows the wellbore schematic and the results of a production logging tool (PLT) run performed before the RPM treatment. Although the PLT clearly identified the intervals contributing to most of the water production, the same intervals were also producing a significant amount of oil. The treatment consisted of pumping 180-bbl of WaterWeb service. After the treatment, the well began producing at 2400-BFPD, 1560-BOPD, 840-BWPD, and 35 percent water cut. Production had stabilized to 850-BFPD, 510-BOPD, 340- BWPD, and 60 percent water cut.
