A casing expansion tool or CET would be inclusive of an expansion module for expanding casings along with a drive module for driving the expansion module. It would be pertinent to mention here that the diameter of the open hole could be kept consistently by the expansion tool. It would be done so that the drilling of mono-hole well along with the completion operations could be carried out with ease. In addition, the expansion tool has also been specifically suitable for the constructions in complex, deep, and ultra-deep wells.
The emphasis laid on safety
During the oil and gas filed well drilling operations, it would need you to put casings downhole to make the most of stratum blocking. It would be essential to make sure about the safety in the target layer. In the sequence of wellbore casing structure, with the increase in the number of casing layers in the well, the casing size along with the size of the borehole would be reduced progressively. It would also increase the borehole taper. It would be done so that the target depth could not be reached in the complex, deep, and ultra-deep wells of subsequent operations. It would be affected by the relatively small sizes of boreholes.
Therefore, it would need you to improve the wellbore structures along with the drilling and completion techniques. It would help you ensure that a continuous borehole size along with the completion of the inner diameter is secured along with the drilling of deeper wells.
The casing expansion tool would be able to maintain a continuous borehole size in the drilling operations. These would be specifically suitable for the construction of the complex, deep, and ultra-deep wells. The present disclosure would further relate to a method of expanding casings by using the same process.
The casing expansion tool could expand under the hydraulic pressure exerted on the casing expansion tool from on the ground. It would be done to facilitate the operations.
Claims made by the casing expansion tool
The casing expansion tool comprises an expansion module to expand a casing along with a drive module for driving the expansion module to expand. The casing expansion tool comprises a support area downstream along with a transition area for supporting the area along with the connection area. The support area would be constructed to form a cone with the small end facing upstream.
It would be pertinent that you look for the right company to handle your specific casing expansion tool needs in the best manner possible.
