摘要

2142112 9429562 PCTABS00034 A scoophead/diverter (510) is presented which is installed at the junction between a primary (16) wellbore and a lateral branch (72) and which allows the production tubing (298) to be oriented and anchored. This scoophead/diverter (510) further provides dual seal bores (380) tying back to the surface with either a dual packer completion or a single tubing string completion utilizing a selective re-entry tool (460). The scoophead/diverter (510) comprises a scoophead (292), a diverter sub (294), two struts (296, 297) as connecting members between the scoophead (292) and diverter sub (294) and a joint of tubing (298) communicating from the scoophead (292), through the diverter sub (294), and to the primary wellbore (16). The scoophead (292) has a large (302) and a small (300) bore. The large bore (302) is a receptacle for a tie back sleeve (350) run on top of the lateral wellbore string, and the small bore (300) is a seal bore to tie the primary wellbore back to surface. Below the scoophead (292), a joint of tubing (298) is threaded to the small bore (300).
