Abstract: A bridge plug for a well includes an actuator member that moves from a first position such that the bridge plug is in a retracted position and a second position such that the bridge plug is in a deployed position. The bridge plug includes a slip section comprising one or more slips that grip a surface radially outward of the bridge plug in the deployed position and a petal section positioned downward of and adjacent to the slip section, the petal section comprising a plurality of petals that fan radially outward from the bridge plug in the deployed position to catch a slurry. The bridge plug also includes a centralizer section positioned downward of and adjacent to the pedal section, the centralizer section having a plurality of centralizers that ramp outwardly in an upward direction in the deployed position for centralizing the bridge plug.

Abstract: Wire retrieval device to cut and recover wire or cable from a well. The wire retrieval device is suited for, among other applications, the retrieval of metallic, non-metallic, or composite wires from a wellbore. A method and system for retrieving a wire or cable from a well using a wire retrieval tool operable to cut a downhole wire and retain the cut segments in a holding cavity within the tool.

Abstract: Disclosed is an improved tension member or slickline used in wellbore intervention operations. One exemplary tension member includes a first portion comprising a metallic material and having a distal end, a second portion comprising a non-metallic material and having a proximal end, and a joint coupling the proximal end of the second portion to the distal end of the first portion.

Abstract: An emergency shelter includes a number of reinforced walls that define a substantially enclosed interior space in which people can enter in emergencies; a doorway opening formed in at least one of the walls to permit entry into and exit from the interior space; a door mounted over that doorway opening; and a latching assembly for latching and locking the door in its closed position. The door is configured to slide horizontally relative to the doorway opening between an open position and a closed position so that it can be opened even when debris is blown up against it. The shelter also includes a door jamb adjacent the doorway opening for receiving and partially surrounding a leading edge of the door to prevent movement of the door along an axis transverse to the horizontal sliding direction of the door so that the door does not cave in when struck by debris.

Abstract: Cables, systems, and methods are disclosed that provide for the monitoring of a cable being deployed to a borehole. Such systems may include a cable having one or more markings at regular intervals. Each marking includes marking data that may be alphanumeric characters, bar codes, ring codes, or a quick-response code. The system also includes a controller that is operable to receive, store, and transmit marking data, and a reader that is operable to read the markings and to transmit marking data to the controller. The marking data may be associated with cable data that is stored in a database to convey information about the cable, such as the origin, mechanical properties, and usage history of the cable.

Abstract: A single phase fluid sampler system and associated methods. A fluid sampling method includes the steps of: receiving a fluid sample into a sample chamber of a fluid sampler; pressurizing the fluid sample using a pressure source; and increasing pressure in the pressure source while the pressure source is in the well, thereby applying increased pressure to the fluid sample in the sample chamber. Another method includes the step of applying pressure to the well to thereby increase pressure in the pressure source, and to thereby increase pressure on the fluid sample. A fluid sampler system includes a fluid sampler with a sample chamber, a pressure source for pressurizing the sample chamber, and a device which operates to increase pressure in the pressure source while the fluid sampler is in the well.

Abstract: A disclosed method of downhole tool system development comprises: receiving specifications of a downhole tool system that comprises multiple strings, each string having one or more components; and checking for interference between the multiple strings in an initial position. A disclosed system comprises: a memory that stores software; and a processor coupled to the memory to execute the software. The software causes the processor to provide a graphical user interface that enables a user to specify a downhole tool system having multiple strings, and to test the strings for diametrical overlap attributable to relative motion of the strings.
