oil and gas pipeline is API 5L and can be mild, medium and high. Vref1 titleMonobore completion techniques as potential solutions m dateNovember 2013 accessdate locationNottingham, UK Reference Copied to Clipboard. Kinematic Seal The conventional rubber pack-off ring is divided in to a collection of paired tapered blocks on the basis of the validated concept of unidirectional blow-out preventer seal ram that can undo the above mentioned limitations of the sealing element. It has been found that the tubing sized monobore completions can develop effective and efficient complex multi-layer reservoirs. With the contingency plan the goal is then set to allow the operator to isolate zones possessing reactive shales, formations of low fracture gradient or other drilling limitations with out reducing the casing and size of the hole in the reservoir.

Furthermore, this system enables the operator to efficiently and effectively exploit the multi-zone wells, which also include high temperature reservoir, since it inhibits the wire tracking caused by the landing nipple seal bores and the completion packer based on the rubber seals.
The contingency shoe run accompanied by the intermediate liner works as the normal casing shoe, however, it also provides a recess area and location profile for the liner, if required. The most serious disadvantage is its low resistance to corrosion which makes it a requirement for internal and external protection, with galvanising the most commonly used method6.

It is also useful for pipelines in cold regions because it also retains its strength in low ambient temperatures9, for example down to -400c. 10.4 Performance of Monobore Systems. It could be seen from the chart that the cost for 30 inches carbon steel line is 83 points compared to 187 points for Duplex steel of the same size. So, this chapter will focus on the various methods of monobore completions since the application of the right method will be most beneficial for the well completion. Studies and researches on the reliability of carbon capture and sequestration storage (CCS) wells have been carried out.
