Patent ID: 8628121

Claim:
A system for use in a wellbore, wherein the system comprises: a. a tubular threaded seal connector comprising: (i) a coupling body, wherein the coupling body comprises: 1. a first coupling end; 2. a second coupling end; and 3. a J-area located between the first coupling end and the second coupling end; (ii) a first chamfer formed on the coupling body adjacent to the first coupling end; (iii) a first seal engagement portion formed on the coupling body adjacent to a first shoulder formed on a portion of the J-area, wherein the first seal engagement portion comprises: 1. a first anti-galling seal connected with the first shoulder by a first anti-galling relief portion; and 2. a first relief groove connected with the first anti-galling seal by a first seal guide surface; (iv) a first threaded engagement portion formed on the coupling body between the first chamfer and the first seal engagement portion, wherein the first threaded engagement portion comprises a first imperfect first thread adjacent the first chamfer and a first imperfect last thread adjacent the first seal engagement portion; (v) a second chamfer formed on the coupling body adjacent to the second coupling end; (vi) a second seal engagement portion formed on the coupling body adjacent to a second shoulder formed on another portion of the J-area, wherein the second seal engagement portion comprises: 1. a second anti-galling seal connected with the second shoulder by a second anti-galling relief portion; and 2. a second relief groove connected with the second anti-galling seal by a second seal guide surface; (vii) a second threaded engagement portion formed on the coupling body between the second chamfer and the second seal engagement portion, wherein the second threaded engagement portion comprises a second imperfect first thread adjacent the second chamfer and a second imperfect last thread adjacent the second seal engagement portion; b. a first tubular connected with the first coupling end; c. a second tubular connected with the second coupling end; and wherein the system minimizes torque applied to the first and second tubulars being coupled to the threaded seal connector.
