Provided is an acoustic housing including a cover including a first perimeter defining an open cover portion, the cover having a cover length, and a cover height, and a body including a second perimeter defining an open body portion, wherein either the first or second or both perimeters are chamfered, configured to receive one or more electrical components and to sealingly engage with the first chamfered perimeter, the body having a body length, a body height, and an under-surface, and the body including an engagement portion projecting from the under-surface and having an engagement length, an engagement height, and an engagement surface configured to engage an outer surface of a tubular.

Acoustic housing for tubulars

A system for downhole telemetry is provided herein. The system employs a series of communications nodes spaced along a tubular body in a wellbore. Each communications node is associated with a sensor that senses data indicative of a formation condition or a wellbore parameter along a subsurface formation. The data is stored in memory until a logging tool is run into the wellbore. The data is transmitted from the respective communications nodes to a receiver in the logging tool. The data is then transferred to the surface. A method of transmitting data in a wellbore is also provided herein. The method uses a logging tool to harvest data in a wellbore from a plurality of sensor communications nodes.

Wired and wireless downhole telemetry using a logging tool

A method of recovering hydrocarbons includes forming a first electrode by creating a first hydraulic fracture within the subsurface formation and pumping a first electrically conductive material into the first hydraulic fracture; forming a second electrode by creating a second hydraulic fracture within the subsurface formation and pumping a second electrically conductive material into the second hydraulic fracture; electrically connecting a first power transmitting mechanism to the first electrode; electrically connecting a second power transmitting mechanism to the second electrode; and heating the subsurface formation between the first electrode and the second electrode by transmitting an electrical current via the first power transmitting mechanism to the first electrode and via the second power transmitting mechanism to the second electrode and by flowing the electrical current from the first electrode to the second electrode. The electrical current substantially includes a frequency between 60 Hertz and 500 Kilohertz.
