Abstract
A connection apparatus is adapted to allow connection of one substantially tubular member to another substantially tubular member. The connection apparatus includes a male connecting member and a female connecting member. Cooperating attachment mechanisms are provided on the male and female connecting members. Each of the male and female connecting members includes at least one primary surface adapted to form a primary joint and at least one secondary surface adapted to form a secondary joint. The at least one primary surface may be adapted to form a primary load bearing shoulder joint. The at least one secondary surface may be adapted to form a secondary load bearing shoulder joint. The connection apparatus may provide a double shoulder high torque connection for downhole tubular members. A double acting hydraulic jar is also disclosed.
