Abstract: A sand separation system for continuous sand disposal is disclosed. It includes a sand catching vessel to receive a multi-phase fluid stream (e.g., oil and gas production) containing settleable solids such as sand. A siphoning conduit connected to the vessel's lower end facilitates for continuous sand disposal. Continuous sand disposal is an operational improvement over conventional batch sand disposal systems. The separation system may feature a control valve on the siphon conduit to regulate sand flow and a water inlet to inject water into the sand collecting vessel. This continuous sand disposal design improves operational efficiency by avoiding separator downtime caused by batch removal of accumulated sand.

The piston sleeve is axially shiftable upon application of external annular pressure against the atmospheric chamber shearing a shearable connection, such that the piston sleeve axially shifts to disengage the anchor latch mechanism.

Abstract: The position of a droppable object (e.g., a cementing plug or drillpipe dart) in a cased wellbore may be determined in real time during a cementing operation. A pressure data acquisition system is installed at a wellsite and a pressure transducer is installed at the wellhead. As the droppable object travels through casing it encounters regions with a positive or a negative change of inner cross-sectional dimension. The droppable object generates a pressure pulse as it passes through the regions. The pressure pulse and associated reflections are detected by the pressure transducer, and the signals are processed mathematically to determine the position of the droppable object. Special casing joints may be installed that comprise positive dimensional upsets that have a size of at least 3 mm. Such upsets may ensure the generation of pressure pulses of sufficient magnitude for detection by the pressure transducer.
