摘要： A tubular string includes a first tubular member with a pin end with pin threads and a pin external load shoulder. The tubular string also includes a second tubular member with a box end with a box external load shoulder and box threads, the pin threads being threadable into the box threads to form a connection, wherein the pin external load shoulder has an outer diameter (OD) that is different than an OD of the box external load shoulder. A load distribution sleeve is locatable between the first and second tubular members when threaded together and includes a first end facing the first tubular member and a second end facing the second tubular member, wherein the ODs of the load distribution sleeve first and second ends match the ODs of the pin and box external load shoulders respectively. The load distribution sleeve contacts the pin and box external load shoulders and distributes a make-up load between the pin and box external load shoulders when the connection is made up.

摘要： A plugging system for plugging a cased well in a single trip downhole. The plugging system may include a tool string positionable within the cased well and including a bore and a downhole tool coupled to the tool string. The downhole tool may include a first perforating gun, an upper resettable packer, a lower resettable packer, and a flow-through assembly. The first perforating gun may be operable to perforate the casing of the cased well. When the downhole tool is positioned in the cased well, the upper resettable packer may be uphole of the first perforating gun. When the downhole tool is positioned in the cased well, the lower resettable packer may be downhole of the first perforating gun. The flow-through assembly may be positioned between the upper resettable packer and the lower resettable packer and operable to flow fluids into a bore of the cased well.

摘要： Embodiments relate generally to systems and methods for pre-cooling a natural gas stream to a liquefaction plant. A system may include a compressor configured to receive a first natural gas stream at a first pressure and produce a second natural gas stream at a second pressure; an exchanger, wherein the exchanger is configured to receive the second natural gas stream as the second pressure and cool the second natural gas stream to produce a cooled natural gas stream; and an expander, wherein the expander is configured to receive the cooled natural gas stream and expand the cooled natural gas stream to produce a chilled natural gas stream from the second pressure to a third pressure. An LNG liquefaction plant system, wherein the refrigeration content of the external or internal refrigerant is used to liquefy and sub-cool a natural gas stream to produce liquefied natural gas (LNG) in a cold box or cryogenic exchanger. The refrigerant may be an external gas (N2) or an internal (CH4 - BOG) refrigerant working fluid expanded and compressed in a twin compander arrangement and compressed by a refrigerant compressor, or an external single mixed refrigerant (SMR) working fluid compressed by a refrigerant compressor and expanded thru a JT valve.

摘要： A method and systems for perforating a formation surrounding a borehole that include placing a perforating gun assembly into the borehole, the perforating gun assembly including a gun body comprising a connector and a shaped charge within the gun body. The shaped charges are detonated, thereby producing a shock wave in the gun body. The shock wave propagating through the gun body is attenuated using a shock attenuation feature in the gun body to decrease a stress from the shock wave communicated to the connector.

摘要： A system and method for analyzing a gas in a drilling fluid involves a degasser operable to separate the gas from the drilling fluid. A gas analyzer in fluid communication with the degasser receives a sample of the separated gas and determines a property of the gas. A controller in communication with the gas analyzer automates the operation of the gas analyzer by adjusting a parameter of the separated gas sample as the gas sample is supplied to the gas analyzer.
