摘要:
An improved well packer for use in sour gas wells is disclosed. The improved packer includes a cylindrical mandrel encircled with a resilient metal seal ring, means for anchoring the packer at a predetermined vertical depth, means for radially expanding the seal rings so as to cause sealing engagement with the casing and mandrel, and ratchet means for maintaining the seal rings in expanded form. The packer is adapted to be run into the cased wellbore on tubing and is particularly useful in sour gas wells.

Systems, methods, and computer program products are provided for tracking one or more items. In one exemplary embodiment, there is provided a method for tracking one or more items. The method may include periodically detecting, by a sensor device, sensor information of the one or more items, and periodically transmitting, by the sensor device, the sensor information. The method may also include determining if the one or more parties is authorized to receive the sensor information. The method may also include transmitting the sensor information to the one or more authorized parties. The method may further include determining if the one or more parties is authorized to receive the sensor information and the periodically transmitting the sensor information to the one or more authorized parties based on a set of one or more permissions that grants or restricts access of the one or more parties to the sensor information based on the set of one or more permissions.

Systems, methods, and computer program products are provided for accessing information regarding one or more shipments. There is provided a computer-implemented method for accessing information regarding one or more shipments. The method includes receiving sensor information associated with the one or more shipments at a tracking center. The method also includes analyzing rules associated with a party to determine whether the party is authorized to access the received sensor information. The method further includes restricting the party from accessing the received sensor information based on the analyzed rules.

A high performance carbon steel tubular for critical Oil Country applications and an improved process for its preparation are disclosed. The tubular is particularly adapted for use in deep wells where the tubular may be subjected to high pressure, wide temperature ranges, and/or corrosive environments, which may include hydrogen sulfide, carbon dioxide, and brine water, together with hydrocarbons. The process comprises forming a bloom from a modified 41XX killed steel, upset forging and piercing the steel bloom into a cylindrical extrusion billet, cold machining the inside and outside diameters of the extrusion billet to be concentric and cold machining the nose of the extrusion billet, reheating and extruding the billet to form an extruded shell, intercritically heat treating the shell, removing surface defects, cold working the tubular shell to finished dimensions, intercritically heat treating the sized tubular, and quenching and tempering the finished tubular.

摘要:
Certain high strength alloys lacking resistance to hydrogen embrittlement are cold worked and heat treated utilizing critical preselected conditions to result in a unique alloy having increased resistance to hydrogen embrittlement without unacceptable loss of strength. It is theorized that this unexpected improved resistance correlates with the concentration of certain elements, such as phosphorus and sulfur as impurities on the crystallographic boundary surfaces of the alloy.

摘要:
A high pressure, antigalling, thread interference pipe connection for use with well pipe includes pin and box members, the thread pitch lines of which are curved at the entrance of the box member and at the nose of the pin member so that sharp corners on the threads at the end of one member do not engage the threads of the other mating member and, also, so that pressure due to thread interference is built up in a smooth fashion over several threads rather than as a sharp pressure spike created by the first threads of one member engaging the threads of the other mating member. In addition, the pitch diameters of the threads of the pin and box members are selected so that makeup of the pin and box members occurs only on full height threads.
摘要:
Controlling information resources involves accessing a control definition of a number of control definitions associated with a first party and a second party. The first party has a first information resource and the second party has a second information resource, where the first information resource is in communication with the second information resource. The control definitions define a practice for monitoring the second information resource, where each control definition has a condition and a consequence. Meta-data is received from a second monitor of the second information resource, where the meta-data describes operation of the second information resource. The condition is applied to the meta-data in order to monitor the second information resource.
