摘要： The invention provides a jockey wheel assembly (1) for a caravan (4) or other trailer. The jockey wheel assembly includes a wheel (28) for engaging the ground, a body member (10) for secure attachment to the caravan, a top portion (8) and a bottom portion (12). The body member (10) is elongate and substantially hollow and extends along a first axis between the top portion (8) and the bottom portion (12). The wheel (28) is rotatably mounted to the bottom portion (12) and the top portion (8) includes a first rotatable member (14). The jockey wheel assembly (1) further comprises drive means for coupling the first rotatable member (14) to the wheel (28) such that rotation of the first rotatable member (14) causes rotation of the wheel (28). The drive means includes a drive shaft (46) that extends through the body member between the top and bottom portions (8, 12). At least one of the top portion (8) and the bottom portion (12) is removable by a user.

摘要： A method and system for determining a position of a second production wellbore. The method may comprise inducing a first current into a first conductive member with a first source, emitting a first magnetic field generated by the first current from the first conductive member into a formation, inducing a second current into a second conductive member with a second source, emitting a second magnetic field generated by the second current from the second conductive member into the formation, disposing an electromagnetic sensor system into the second production wellbore, recording the first magnetic field with the at least one sensor from the formation, and recording the second magnetic field with the at least one sensor from the formation. The system may comprise a first source, an electromagnetic sensor system, at least one sensor and an information handling system configured to determine the position of the second production wellbore.
