Abstract: A field instrument and system for obtaining pressure, flow and temperature data from a facility. The field instrument includes an enclosure having an opening therein. An integrated analog sensor is sealingly contained within the opening. The field instrument further contains an external analog sensor. An analog to digital converter converts the analog signals to digital readings. An external digital sensor is also provided, with the digital output being communicated through a second opening within the enclosure. A control member that receives, stores and processes the digital readings is positioned within the enclosure. A communication module is included to transmit the digital readings to a remote computer. The communication module allows for two way communication between the field instrument and remote computer. The remote computer may be a server that allows for access by many users. The communication module also allows for locally accessing the digital readings via a serial port to a local terminal.

Abstract: A method of drilling a well includes calculating and estimating the dip angle, wherein said estimated dip angle being based on offset well data, seismic data, core data, pressure data. Next, the method includes drilling a well with a logging while drilling tool using the estimated formation dip angle so that real time logging data is generated along with the drilling data and calculating an instantaneous formation dip angle. Next, the real time logging data is obtained and a target formation window is projected ahead of the well path that includes a top of formation and a bottom formation. The method includes monitoring the real time logging and drilling data and drilling the well through the target formation window. The method further includes changing the estimated instantaneous formation dip based on the obtained data and adjusting the target formation top window and the bottom formation window.

Abstract: A tubular handling device. The device includes a plurality of slips, and wherein the slips have an arcuate inner face that has a longitudinally disposed slot and a ledge therein. The device further comprises an insert having a shoulder that is configured to fit within the ledge, and wherein the insert is capable of transferring a load from the shoulder to the ledge. In one preferred embodiment, the outer portion of the slips have a taper of greater than 11 degrees and a complementary bowl insert is provided that has a matching taper. A method of handling tubular members on a drilling rig is also disclosed.

Abstract: A downhole cleaning tool (10) for oil and gas wells. Brushes, scraper, wipers (32) and the like are mounted on a sleeve (14) over a tubular body (12), and the members successively moved towards and away from an inner surface of a tubular to be cleaned. Movement is created by a jarring action on the tool with the sleeve traveling over undulating profiles (26) on the body to actuate the cleaning members. The tool may be deployed on a slickline or wireline.

Abstract: A downhole tool (10) for selectively circulating fluid in a borehole is disclosed. The tool operates via the use of a combination of deformable drop balls (36) and smaller hard drop balls (40). In use a deformable drop ball (36) moves a sleeve (20) exposing a radial port (30,32) to provide fluid circulation radially from the tool. The smaller drop ball (40) can then obstruct the radial port (32,30) and by the increased pressure the deformable drop ball (36) is extruded through the tool. The resulting pressure differential as the drop ball (36) moves causes the sleeve (20) to rise, releasing the smaller drop (40) ball and closing the radial port (32,30). The process can be repeated to selectively circulate fluid through the tool.

Abstract: A reciprocating full flow tester valve is provided with a shock absorber and tolerance adjustment device for absorbing an impact between a power mandrel of the tool and an operating assembly of the tool. An improved hydraulic impedance system is also provided for providing a time delay in telescopingly collapsing movement of the tool when weight is set down on the tool to open the tester valve.

Abstract: A progressive cavity pump for inflating downhole inflatable packers. The pump includes a case defining an inlet port and an outlet passageway therein in which the outlet passageway is in communication with the inflatable packer at a location below the pump in the well bore. An elastomeric stator is disposed in the case between the inlet port and the outlet passageway, and the stator has a convoluted inner surface. A rotor is disposed in the stator and rotatable with respect thereto. The rotor defines a convoluted outer surface thereon engaged with the inner surface of the stator such that a plurality of progressive pumping cavities are defined therebetween. As the rotor is rotated within the stator, fluid is moved from one cavity to the next, thereby pumping fluid from the inlet to the outlet. The rotor has a central opening therethrough which provides communication between the packer and an upper testing string portion. The rotor is supported on bearings and/or bushings.

Abstract: A burner apparatus for burning hydrocarbons. The apparatus comprises a body defining a plurality of nozzle ports therein, each port facing in a different direction, a discharge nozzle disposed in each nozzle port, and a water ring assembly disposed around the body. Each nozzle is held in place by a retainer such that a first gap is defined therebetween, and a retainer nut is attached to the body adjacent to the retainer such that a second gap is defined between the retainer and the nut. This second gap acts as an air discharge orifice and is in communication with an air passage defined in the body. The water ring assembly comprises an outer ring and an inner ring which combine to define an annular water chamber therebetween. The water chamber is in communication with a plurality of notches in the outer ring which act as water discharge nozzles for directing a water stream toward the burning petroleum and air stream discharged from the apparatus.

Abstract: Method for determining the volume of fluid produced and other production characteristics from a subterranean formation during a drill stem test based on determining the location of well fluid within the drill stem tubing by measuring the travel time of an acoustic signal reflected from the well fluid.

Abstract: A burner nozzle for burning petroleum products. The burner nozzle includes a tube portion with a burner nozzle insert disposed therein. A nut is threadingly engaged with the tube portion to hold the insert in place. The insert has a substantially conical nozzle portion with an inlet portion extending substantially perpendicular to a longitudinal axis of the nozzle portion. The inlet portion defines a plurality of inlet ports therethrough. The inlet ports are angled with respect to the longitudinal axis and have an outlet end adjacent to an inner surface of the nozzle portion.
