Abstract
A technique for manufacturing a millable bridge plug for plugging of a wellbore during, for example, a fracturing operation. A bridge plug is constructed with an obstructed internal passage. The obstructed internal passage is formed by winding a composite material about a wrapping mandrel having at least one cylindrical part and a solid part coupled thereto. The cylindrical part is removed after a curing process leaving a mandrel with a plugged internal passageway upon which a seal member combined with a plurality of slips for engaging a surrounding wall, e.g. a surrounding wellbore wall, may be coupled.
