Method for, and the construction of, a long-distance well for the production, transport, storage and exploitation of mineral layers and fluids

摘要

A method is described for the construction of an arrangement of Extended Reach Wells (ERW) for the production, transport, and exploitation of mineral layers, in that an offshore reservoir of fluids is initially penetrated by an initial well, followed by penetration by a multilateral well, close to or connected at the end of the drilling section of the multilateral well to the end of the drilling section of the initial well. A well of long distance is therefore formed, connected hydraulically at one end of the initial well to the production unit. The resulting long-distance well allows for the drainage of the reservoir in deep and extremely deep water from a platform in shallower water.
