Abstract: Method and system that permits explosive operations to be conducted concurrently with drilling and other wellsite operations involving an electrical top drive mechanism or other components that utilize electricity are disclosed. A platform is placed at a location where subterranean operations are to be performed. A first well bore is drilled in a formation using drilling equipment on the platform by activating a top drive. Concurrently with drilling the first well bore, a perforating operation is performed in a second well bore extending from the platform. The perforating operation is performed using a perforating gun that comprises at least one of an electric isolator and an explosive isolator. The perforating gun is activated when the perforating gun reaches a safe depth.

Abstract: Packers may be inflated within the wellbore to engage and isolate a portion of the wellbore wall. Charges included within the packers may then be fired to perforate the formation. According to certain embodiments, the charges may be located within drains in the packers that can be subsequently employed to sample the surrounding formation.

Abstract: This disclosure is related to a perforator tool and a method of using the perforator tool to perforate a formation. The perforator tool can include a first and second sleeve and optionally a third sleeve. The perforator tool can also include at least one perforation opening and at least one circulation port. The sleeves are slidably disposed within the perforator tool and can be displaced to permit perforation of the formation, block the perforation openings and open circulation ports.

Abstract: Methods and apparatus are described to drill and complete wellbores. Such wellbores include extended reach horizontal wellbores, for example in shales, deep subsea extended reach wellbores, and multilateral wellbores. Specifically, the invention provides simple threaded subassemblies that are added to existing threaded tubular drilling and completion equipment which are used to dramatically increase the lateral reach using that existing on-site equipment. These subassemblies extract power from downward flowing clean mud, or other fluids, in an annulus to provide additional force or torque on tubular elements within the wellbore, while maintaining circulation, to extend the lateral reach of the drilling equipment and completion equipment. These added elements include combinations of The Leaky Seal™, a Cross-Over, The Force Sub™ and The Torque Sub™. The use of such additional simple elements allow lighter drilling equipment to be used to reach a given lateral distance, therefore reducing drilling costs.

Abstract: The exemplary embodiments relate to apparatus and methods for increasing the longevity of an RCD at a wellbore, including a bearing assembly configured for operating in the RCD. The bearing assembly is configured for reducing pressure proximate the bearing assembly including reducing pressure in a radial seal. Top and bottom seals are mounted against a wear sleeve adjacent to an inner member housed within the bearing assembly. The wear sleeve is configured to be sealed by the top seal and the bottom seal as the inner member rotates in the RCD. A pressure reduction system mounted with the RCD is configured to apply pressure via a wellbore pressure between the top seal and the bottom seal, which is lower relative to a pressure above the top seal, and which is higher relative to a pressure below the bottom seal.

Abstract: A tubular string is run into a wellbore with a remotely actuated valve near a lower end adjacent a cementing shoe. The valve is triggered to operate without intervention such as by mud pulses generated at the surface and recognized by a sensor linked to a processor adjacent the valve to trigger the valve to close. Alternative actuation systems are envisioned for the valve that is located near the cementing shoe.

Abstract: Methods and apparatus for diverting fluids either into or from a well are described. Some embodiments include a diverter conduit that is located in a bore of a tree. The invention relates especially but not exclusively to a diverter assembly connected to a wing branch of a tree. Some embodiments allow diversion of fluids out of a tree to a subsea processing apparatus followed by the return of at least some of these fluids to the tree for recovery. Alternative embodiments provide only one flowpath and do not include the return of any fluids to the tree. Some embodiments can be retro-fitted to existing trees, which can allow the performance of a new function without having to replacing the tree. Multiple diverter assembly embodiments are also described.

Abstract: A flow control assembly for regulating fluid flow in a wellbore is disclosed. A remote-open ICD is opened in response to swelling of a swellable actuator. The swellable actuator can move a flow regulator radially, circumferentially, etc., such that flow is allowed through the regulator. Alternately, the swellable actuator can move one or more valve members to an open position thereby allowing fluid to flow across the valve and to the flow regulator. The swellable actuator can be swelled in response to introduction of chemicals or heat. A guide mechanism can be used to control swelling of the actuator or movement of the regulator device or valve member.
