Abstract: A mill (400) is provided for milling an opening in a tubular, comprising a body (402) having an upper end connectable to a drill string, a lower end provided with milling and/or cutting material, a first fluid flow bore (406) extending generally axially of the body, a second fluid flow bore extending from the first fluid flow bore and opening in the exterior of the body (402) substantially on the rotational axis thereof, and a plurality of inclined fluid flow bores (416) extending from the first fluid flow bore (406) and opening in the exterior of the body around the second fluid flow bore. The second fluid flow bore is lined with a layer of milling and/or cutting material (414).

Abstract: A tool for milling an item in a wellbore includes a number of cutting blades 210 which protrude from a surface 208 of the tool. The blades 210 are attached to the face 208 in a non-planar configuration which can be in the form of an L-shape (fig 7). A reinforcing member 216 may be present to prevent buckling of the blades 210.

Abstract: Det er utviklet en metode som gjør det mulig for operatøren å gå inn igjen i et primært brønnhull fra et lateralt brønnhull etter at det laterale brønnhullet er blitt fullført. Metoden omfatter generelt steg for å lokalisere en skjæreanordning slik som et fresehode nært et rør slik som et foringsrør inne i et brønnhull, og rotasjon av fresehodet mens man opprettholder en aksial posisjon av fresehodet i forhold til foringsrøret for å initiere en åpning, og rotere og aksialt føre fresehodet fram for å fullføre åpningen. I tillegg omfatter metoden en nedre hullsammenstillling som forenkler gjeninnføringen i det primære brønnhullet fra et lateralt brønnhull. Den nedre hullsammenstilllingen omfatter generelt en drillkrage eller en armen tung rørstruktur, og en fresemaskin. Fresemaskinen har en kropp og skjærestrukturer. Skjærestrukturene påfører lateralt trykk mot et omliggende rør for å danne en innledende skjøt gjennom veggen av røret.
