Video Allegro CD Service: Improving Well Economics
Directional casing-while-drilling service.
Specifically designed to access additional reserves in thru-tubing reentry drilling applications, the CTDirect coiled tubing directional drilling system enhances reservoir exposure and eliminates the need to remove existing completions or production tubing. The result is maximized production and improved rig and cost efficiency without interrupting production operations or incurring reservoir damage.
The CTDirect system is specifically designed to access bypassed reserves and extend production in underbalanced, short-radius, and thru-tubing reentry drilling applications. The system features a 410° continuously variable electrical toolface orienter with real-time bidirectional data communication.
For underbalanced or managed-pressure drilling operations, the CTDirect system minimizes the risk of reservoir damage while keeping your well live. Compared with overbalanced conventional drilling, underbalanced wells drilled with the system typically have earlier payout and lower well stimulation costs.
The CTDirect system provides measurement of downhole drilling mechanics data, shock and vibration, inclination, azimuth, and toolface data. This data is seamlessly transmitted to surface, where it is continuously monitored at the wellsite for precise directional steering and immediate motor stall detection.
Eliminating a dedicated liner run through a high-loss gassy salt zone reduced rig time by multiple days.
Allegro CD service eliminates NPT and saves >4 d, offshore Dubai.
Anchors the BHA to casing to enable casing while drilling using the Allegro CD service.
