A Study To Determine Necessity of Pilot Holes When Drilling Shallow Gas Zones Using Top Hole Dual Gradient Drilling Technology

When drilling offshore, shallow gas hazards are a major concern because of their potential to cause a major blowout. This is a special concern when drilling in shallower water, where the gas influx reaches the rig sooner. A common practice used to avoid the potential dangers of shallow gas is to dri...
