Tool Enables One-Trip Completions in Multiple Deepwater Pay Intervals

摘要

When designing deepwater wells with long or multiple pay zones, completion specialists face economic and technical problems whose solutions are often in conflict. Typically, these long pay zones include variations in fracture pressures, permeability, or other reservoir parameters. In trying to stimulate the entire length as one zone, it can be difficult to manage the many stimulation requirements, such as volume, rate, and pressure factors. The result can be poor reservoir coverage and uneconomic production. On the other hand, traditional multizone sandface completions can impair well economics because of the rig time required.
