A method that allows the operator to re-enter a primary wellbore from a lateral wellbore after the lateral wellbore has been completed. Reentering lateral wells is necessary to perform completion work, additional drilling and/or remedial and stimulation work
An installation method based on the onshore assembly of long sections of rigid steel pipeline, about 1 km long, which are welded together as they are spooled onto a vessel-mounted reel for transit and subsequent cost-effective unreeling onto the seabed. Minimum welding is done at sea
A reel pipelaying vessel which provides for both coating a pipeline and unreeling the same for subsea disposition. With the latest methods joints of pipe are welded on deck and then spooled or wound upon a reel. At a desired location, the pipeline is then placed on the seabed by unwinding the pipe from the reel and straightening it before it is lowered to the seabed.
