3D obstacle-surrounding horizontal well

In September 2008, Orion has designed a 5 well using the same horizontal well farm (1 for 5 multiple branches horizontal well project) at xxx block for PetroChian, after vertical well drilling and for avoiding vertical well from entering into coal production face, Orion has exercised a connection of vertical well with a nearby well program in the southwest direction and re-deployed the main borehole and branches borehole in the northwest direction. Orion has accomplished 3D directional drilling in 3 weeks and met the challenges of difficult drilling job, achieved 4500 meters drilling footage. The well group’s average single well drilling footage was 4700 meters and achieved average single well production in excess of 30,000 cubic meters.

Casing window-opening and side track multiple branches connection horizontal well

It was in 2012 at xxx block in Henan, a casing window-opening and side track multiple branches connection horizontal well, after connection of horizontal well at 215.9 mm borehole with remote (displacement 710.93mm) vertical fiber galss casing external diameter (177.8mm), run in hole 139.7mm casing, run in again inside the casing the retrievable hydraulic multiple-stage anchoring kick off device to run side track and window-opening, drilled in 4 branches wellbores and run in the branches with screens.
