Slant entry well system and method
View Patent ↗A guide tube bundle includes two or more guide tubes. Each guide tube includes a first aperture at a first end and a second aperture at a second end. The longitudinal axis of the first aperture of each guide tube is offset from the longitudinal axis of the second aperture of the guide tube Furthermore, the guide tubes are configured longitudinally adjacent to each other and are twisted around one another.
1. A guide tube bundle, comprising:
two or more guide tubes;
wherein the two or more guide tubes each comprise a first aperture at a first end and a second aperture at a second end;
wherein the guide tubes are configured longitudinally adjacent to each other;
wherein the longitudinal axis of the first aperture of each guide tube is offset from the longitudinal axis of the second aperture of the guide tube; and
wherein the guide tubes are twisted around one another.
2. The guide tube bundle of claim 1 , wherein the angle at which the guide tubes are twisted comprises approximately ten degrees.
3. The guide tube bundle of claim 1 , wherein:
the guide tubes are configured longitudinally adjacent to each other at their first ends; and
the guide tubes are separated at their second ends.
4. A method for orienting well bores, comprising:
forming an entry well bore from the surface;
inserting a guide tube bundle into the entry well bore, the guide tube bundle comprising:
two or more guide tubes, wherein:
the two or more guide tubes each comprise a first aperture at a first end and a second aperture at a second end;
the guide tubes are configured longitudinally adjacent to each other; and
the guide tubes are twisted around one another; and
the longitudinal axis of the first aperture of each guide tube is offset from the longitudinal axis of the second aperture of the guide tube; and
forming two or more slanted well bores from the entry well bore using the guide tube bundle.
5. The method of claim 4 , wherein:
the longitudinal axis of the first aperture of each guide tube is oriented vertically; and
the longitudinal axis of the second aperture of each guide tube is oriented at an angle offset from the longitudinal axis of the first aperture.
6. The method of claim 4 , wherein the angle at which the guide tubes are twisted comprises approximately ten degrees.
7. The method of claim 4 , wherein:
the guide tubes are configured longitudinally adjacent to each other at their first ends; and
the guide tubes are separated at their second ends.
