TwinWells™ Ranging System, HyperLine™ Motor Drill 4,400-ft SAGD Injector Lateral in 7.75 Hours

Drill steam-assisted gravity drainage (SAGD) well pairs, placed 16 ft (5 m) total vertical depth (TVD) on top of one another.
Use the TwinWells active magnetic ranging system to determine accurate wellbore separation.

Weatherford field personnel deployed a bottomhole assembly consisting of the following equipment: a magnetic ranging system, the enhanced electromagnetic (EM) MWD system, the MFR tool, the UGR tool, the Inc-Sonde tool, and the HyperLine 250 drilling motor.
The combination of the non-magnetic drilling motor, Well Placed Survey Management, and the Inc-Sonde tool allowed close-to-bit continuous dynamic rotating inclination for accurate landing of the drilling well.
The TwinWells system provided precise magnetic measurements to determine the proximity of the drilling well to the offset producer wellbore for the entirety of the lateral section.

The Weatherford solution enabled the operator to achieve a faster average rate of penetration (ROP) for the injector lateral.
The drilling technologies provided accurate placement of the injector well to the producer.
The operation only required a sliding time (the amount of time needed to make directional change to the wellbore) of 8%.
