Perform Vertical Pass-By Ranging to 3 Wells on a Single Lateral Leg

Objectives

Drill a 6-leg multilateral well in a heavy oil reservoir in Alberta, with one leg required to be drilled in close proximity to three vertical wells.
Prevent wellbore collisions and maintain a planned separation of 32.8 ft (10 m).

Our Approach

Weatherford field personnel deployed a bottomhole assembly comprising of the following equipment: a rotating magnetic ranging system, the enhanced electromagnetic (EM) HEL system, the MFR tool, the HAGR tool, the dual IDS tool, and the Hyperline 250 drilling motor.
The combination of the non-magnetic drilling motor and the dual IDS tool enabled close-to-bit continuous dynamic rotating inclination, ensuring precise directional placement of the drilling well.
Weatherford wireline services deployed the DeepGuide sensor inside three offset vertical wellbores and used it to conduct gyro surveys of the three wells, thereby reducing positional uncertainty.
The DeepGuide system provided accurate magnetic measurements to ascertain the proximity of the drilling well to the offset vertical wellbores.

Value to Customer

Weatherford expertise and technology enabled accurate measurements of distances to offset vertical observation wellbore to prevent any collisions or damages to either wellbore.
The results accurately measured separation distances between wells for monitoring purposes.
