Abstract: A shear assembly used downhole to actuate a work string function includes a dampening subassembly to dampen the momentum of moving parts following shearing to avoid excessive acceleration and resulting jarring forces within the work string. A dual shear assembly is provided, in which the dampening subassembly prevents inertial force resulting from a first shear from exceeding the threshold for actuating the second, higher threshold, shear mechanism thereby allowing more precise control of the forces applied to the work string to prevent premature shearing of the second shear mechanism. In a specific embodiment, the dampening subassembly is a hydraulic dampening subassembly. The dual shear assembly may be used, for example, to first open a wash port above a tool lodged within the wellbore to loosen debris above the lodged tool, and then to shear the tool from the work string if necessary.

Abstract: A system and method for reporting according to the EU VAT related legal requirements and, in the preferred embodiment, within SAP environment is described. Because the report will aid in legally required reporting for EU VAT, it will also aid in the avoidance of penalties that may be legally imposed for non-compliance to EU VAT rules. This invention will also allow for better reporting and improved EU VAT Reclamation process. The present invention provides for data collection of EU VAT related invoice transactions made electronically based on additional fields which are provided in SAP. Additionally, a new report is created and is run based on input criteria.
