Abstract
A method and system are provided for installing an oriented conduit section in a well-bore having a substantially non-vertical axis. In one example, the system comprises: means for inserting a conduit a the well-bore, wherein the conduit comprises a section to be oriented, means for applying, in the well-bore, a rotating force to the section to be oriented, whereby an oriented section results, and means for fixing the conduit in the well-bore. An instrumented conduit section is also provided, for orientation in a well-bore having a substantially non-vertical axis. Further, a method is provided for using a tool in a well-bore, the method comprising: inserting a casing in the well-bore, orienting the casing in the well-bore, wherein an oriented casing is defined, inserting the tool in the oriented casing, and orienting the tool in the oriented casing.

16. A method of orienting a portion of a conduit in a non-vertical wellbore, the method comprising the steps of:
-
providing an elongated conduit having a conduit portion for orienting in the wellbore, running the conduit into the wellbore; and orienting the conduit portion in the wellbore by detachably connecting a weight to an inner surface of the conduit portion offsetting the center of gravity of the conduit from its rotational axis. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
