Abstract This paper will describe in detail the four-year and six-well journey that was taken by a major operating company in the Norwegian Sector of the North Sea, to perfect the processes required to successfully place two different types of chemical-based chalk consolidation treatments. It will detail the objectives of the operations, the methods employed and the lessons learned. Extensive laboratory testing was initially employed to both verify the efficacy of the treatments in the chalk formation and to qualify all the materials that would be employed (including, but not limited to, coil tubing metallurgy, polymer seals, completion materials, tank linings and high-pressure pumps). This was particularly important as one of the consolidation chemicals employed was corrosive. Further testing was performed at a yard scale, in order to optimise the mixing and pumping processes, and to confirm the general material compatibility. Actual operational procedures varied widely over the course of the six treatments. Lower completion strategies placed in long horizontal laterals included open-hole sections, cased-cemented & perforated intervals as well as sliding sleeves (often with multiple variants on the same wellbore). Additionally, the completion approach utilised both extensively propped fractured and unfractured intervals, adding a further level of complexity. Placement methods included bull-heading down the completion, bull-heading down coiled tubing, bull-heading with diversion and selective zonal placement with coiled tubing-deployed straddle packers. Furthermore, four different methods of storing and pumping the treatments were employed: - platform deck-based with tanks, Heavy-Duty Jack-Up (HDJU) deck-based deployment, dedicated stimulation vessel treatment and fit-for-purpose Platform Supply Vessell (PSV).
