Abstract: An improved baseplate design is described that correct the flexure with a plurality of actuators mounted on top of the base plate. Sensors and a feedback circuit enables the detection of flexure and a corresponding compensating scheme to correct and/or prevent the flexure in order for the baseplate to complete couple with the ground for more accurate seismic survey.

Abstract: Methods and systems operate multiple downhole tools in wells based on hydraulic pressures supplied in control lines. The methods and systems pair each of the tools with a manifold enabling selective actuation of each of the tools from a remote location. Some embodiments include between three and twelve manifold and tool pairs configured for control independent from one another with four of the control lines.

Abstract: A liquefied natural gas (LNG) facility that employs a system to remove incondensable material from one or more refrigeration cycles within the facility. One or more embodiments of the present invention can be advantageously employed in an open-loop refrigeration cycle to remove at least a portion of one or more high vapor pressure components that have accumulated in the refrigerant cycle over time. In addition, several embodiments can be advantageously employed to stabilize facility operation in the event of drastic changes to the concentration of the natural gas feed stream introduced into the facility.

Abstract: Methods and systems for enhanced capture and recovery of core samples from unconsolidated or friable formations are provided using drilling fluids that permit increased overpressures to preserve the ability to cut core samples and to strengthen the core samples obtained. Drilling fluids used during capture and recovery of core samples may comprise a solid particulate loss prevention material having a size range from about 150 microns to about 1,000 microns. The solid particulate loss prevention material prevents fracture initiation and propagation in the subterranean formation to allow the use of higher overpressures than would otherwise be possible. Thus, by circulating drilling fluid in the borehole while drilling a core sample, higher overpressures may be achieved, which have been found to be beneficial during core capture and recovery by maintaining core integrity and avoiding core loss. In this way, core sample integrity is improved, yielding more accurate representations of the subsurface.

Abstract: Methods, systems and designs are provided for removing mercury from crudes. Crude oil is heated to a temperature above 100° C. in a stabilization column for a time sufficient to convert all of the forms of mercury in the oil into the elemental mercury form. The elemental mercury is then stripped from the crude oil by flashing, or preferably by gas stripping with a gas injected at the bottom of the column. Either process transfers the elemental mercury from the oil phase into the gas phase. Elemental mercury can then be removed from the gas phase by methods such as condensation, precipitation, or absorption either alone or in combination.

Abstract: A liquefied natural gas facility employing a heavies removal column having multiple reflux streams. The reflux streams can have different compositions and can be operable to reduce the critical pressure of the fluids within the heavies removal column in order to permit the column to operate at higher pressures without adversely affecting the horsepower requirements of plant compressor/driver systems.

Abstract: The invention relates to a process for two separate seismic crews to work in proximity to one another that would otherwise require expensive time sharing where one crew is a conventional seismic acquisition system and the other is a phase encoded seismic acquisition system. Typically, each recording system would receive seismic energy from the other that neither data set would be very useful. The invention primarily envisions some collaboration between the crews where each adjusts its sweeps to comprise a different time duration so that the energy the other crew's sources are distinguishable in the data set and easily eliminated therefrom. Distinctions may be further enhanced when the two crews use construct their sweeps so that each crew has a distinctly different start frequency and a distinctly different end frequency.

Abstract: An electric sweep type seismic vibrator source of the type used in seismic prospecting for hydrocarbons is provided. In one example, the source uses an engine and generator combination to create electric power for all systems on the source such as driving a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion along with driving the source from location to location through a survey area. A foot is arranged on the bottom end of the rod or piston for contact with the ground and by engaging the grid of motors to push down against the ground in a rapid progression, acoustic energy is created and delivered into the ground for geophones to sense and record.

The source uses an engine and generator combination to create electric power for all systems on the source such as driving a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion along with driving the source from location to location through a survey area. Preferably a foot is arranged on the bottom end of the rod or piston for contact with the ground and by engaging the grid of motors to push down against the ground to create impulses that deliver acoustic seismic energy into the earth for geophones to sense and record. However, the pulses of seismic energy are delivered in a distinctive fashion where different linear motors are deliberately and concurrently providing different signals that create a distinctive composite signature or signal that can be identified in the data record for source separation purpose.
