Noteworthy amongst the deployed technologies are: A Smart Isolation Plug (smart plug) which was deployed during the first-of-its kind replacement of the gas export (GE) riser flex joint (FJ) in the Gulf of Guinea...

... properly, the abandonment plan was broken down into three zones. The first, or lower zone covered the open hole with cement plugs across Oligocene age sands to prevent crossflow and secure reservoir integrity. The next, or middle zone, covered the Miocene age gas sand behind 14" casing. It included two...

... temperature and high pressure, and in the presence of free water molecules, gas-hydrate crystals will start to form. These gas hydrate crystals may accumulate and cause partial or complete plugging of the pipeline in the vertical or horizontal sections of the pipe. Methanol was previously found to be the only...

... Abstract A premium bismuth-based alloy plug system has been developed to achieve a gas tight seal in annuli that cannot be achieved with traditional cement plugs, providing a new methodology for abandoning wells. To date, 35 plugs in total have been run in 30 wells, with this technique...

... and triaxial stress compression experiments on five and seven groups of core samples, which were from well P6 and well P8, respectively. Each group of samples had five plugs with similar depth, one of which was designed for the uniaxial strain experiment and the other four for the triaxial stress experiment...
