| titleOfInvention | Method of forming a wellbore junction |
| abstract | An apparatus (10, figure 1) for creating wellbore junction comprises a diverter / whipstock 14, and a cutting / milling tool 12 to drill a branch wellbore 72 extending outwardly from a main wellbore 66. The diverter / whipstock 14 comprises an inner core 34 and a structure 32 outwardly disposed relative to the inner core 34, the structure 32 being more readily milled than the inner core 34. After a portion 70 of the branch wellbore 72 is drilled, the intersection of the wellbores 66, 72, is sealed by injecting a substance 74, eg. a hardenable epoxy resin composition, into the formation 76. The branch wellbore 72 is then drilled further outward so that a second portion 78 is formed. A liner 80 is cemented in the branch wellbore 72 with its upper and lower ends positioned in the portions 70 and 78 respectively. |
