System and method for rotationally orienting the whipstock assembly
The present invention discloses a downhole subassembly system and method of use. A downhole subassembly is oriented whipstock system subassembly, comprising: a whipstock apparatus, said apparatus comprising a whipstock operable to direct a cutting tool into the sleeve to deflect the side wall surface of the outlet sleeve ; and orienting joint, said joint comprising orienting operatively coupled to said whipstock device at least an upper portion of the lower coupling member and the coupling member engages the upper portion of the coupling member, the lower coupling member when in the unfolded configuration and may be rotationally fixed with respect to the upper coupling member with respect to the rotational movement of the upper coupling member when in the collapsed configuration.
Abstract A very promising spin physics programme will be soon on the way at the BNL Relativistic Heavy Ion Collider (RHIC). By studying the spin asymmetries for various processes (single photon, single jet and W ± production), we will compare the different predictions obtained using some sets of polarized parton distributions, available in the recent literature. We will put some emphasise on the analysis of the anticipated errors, given the event rates expected from this high luminosity new machine and the current acceptance for the detector systems at RHIC.
