Abstract: A liner hanger and packer are set at different times in a single trip without intervention. The running tool has a ball seat that accepts a ball for pressuring up which results in movement of a mandrel with a magnet mounted to it past a valve triggered by the magnetic field. Potential energy is released to set the liner hanger. Further mandrel movement then releases the running tool once the liner is supported by the hanger. After a cement job that starts with confirmation of release of the running tool, the same magnet is moved past another valve adjacent the liner top packer. Another valve is triggered open to release potential energy and move parts that set the packer. The running tool is removed from the liner and brought to the surface.

Each of the one or more cutting elements may include a cutting edge comprising an arcuate peripheral cutting face portion for contacting the borehole. Cutting faces of at least one cutting element on a gage portion of the at least one blade may exhibit a cutting face back rake angle greater than a cutting face back rake angle of cutting elements on at least one other portion of the at least one blade.

Abstract: A magnetic sensor elastometry device (MSED) and a method to perform the whole blood thromboelastography assay. It contains key components, including sample cuvette, detecting head, rotating disc, optical motion detector, and etc; and measures viscoelasticity of whole blood samples. The device optically monitors the physical motion of the magnetically driven rotating disc immersed in the blood sample. The thromboelastograph is recorded by the optical motion detector reading high pulse counts through a gated time window passing through the rotating disc. The device also includes a microcontroller and its embedded firmware to perform the functions of driving the rotating magnetic disc, generating high-frequency pulses, controlling the data pulse time window, as well as handling the user's interface, data analysis, and maintaining communication with an external computer.
