... sidetrack operation can be challenging, particularly when the milling assembly has to cut dual-casing due to the existing well condition and the geological target requirement. The centralizer and casing collar position inside the wellbore is considerably to select the kick-off point and optimize the well's...

After the first phase of re-entry well drilling evolution is established, the second...

... production was always unwanted. The deployment of traditional rig or coiled tubing unit to help restoring production came with considerable cost due to the equipment and personnel requirements. Consequently, PHM continually looked for new techniques to reduce this challenge. Milling on wireline, where...

... or restriction during the next velocity installation. However, operational histories and field performance in terms of the capability to mill resin inside 3 1/2-in. casing were rare. This paper discusses a case study of applying the epoxy resin system, a rigless operation using fiber-optic coiled tubing (FOCT...

... Abstract All wells eventually come to an end, and proper Plug and Abandonment is necessary. To properly abandon a well, casing must be removed and barrier plugs set. There are many viable methods that remove casing; section milling, pilot milling, or cut and pull. While all are effective...
