GEOCONN ApplicationsGeothermal Wells: Prevention of turbulence flow SAGD: Liner for SAGD Wells
Drilling with Casing: For high torque resistance Shale Plays: Full string for shale or tight plays
API BTC
Problem
1. The gap at the center of the coupling can cause turbulence flow.
2. Possible scale buildup at center gap or J area.
3. The Buttress threads have poor leak resistance against gas/steam.
GEOCONN
Solution
1. GEOCONN prevents turbulence flow.
2. The abutment works as a metal seal during production at a high temperature.

HIGH TORQUEThe GEOCONN connection features a high over-torque resistance and a high fatigue resistance. Additionally, the connection offers prevention of turbulence flow as the abutment works as a metal seal under medium tension loads.
BUTTRESS COMPATIBLEGEOCONN is completely interchangeable with API Buttress. All accessories with API Buttress threads can be used in conjunction with GEOCONN.
COMPETITIVE PRICINGThe shorter coupling length of GEOCONN means less material per coupling which equals a lower price per connection.
GEOCONN is compatible with API Buttress accessories, reducing the need to purchase any additional accessories. The same threading tools used for API Buttress are used to manufacture GEOCONN.
Manufacturing of GEOCONNThe manufacturing of GEOCONN is very similar to Buttress with one of the main differences being the shorter coupling length.
GEOCONN Mill Make-up Position The mill end is made up slightly deeper than the center of the coupling to prevent mill end rotation during field make-up. The make-up distances were chosen to provide good leak resistance and prevent any increases in hoop stress.
