To extract additional reserves from an aging well stock offshore Italy, a customer had been performing conventional sidetracked operations followed by stacked cased-hole, frac-pack completions. Despite continuous efficiency gains, the frac-pack operations were too time consuming and costly, and the system designs inherently limited how the wells could be completed. Multiple vertical wells had to be drilled to intersect the multilayered pay zone, and only three to five large, evenly spaced intervals could be completed per well. The well profiles were also limited to low inclination due to gravel pumping.
