Patent number: 9488046Abstract: A method for downhole communication and an apparatus for remote actuation of a downhole tool is disclosed. The method comprises the steps of: programming at least one tag (20) to emit a radio frequency identification signal in the form of a frequency change in a carrier wave; locating a reader (10) responsive to signals emitted from the at least one tag downhole; moving the at least one tag (20) past the downhole reader (10) such that the downhole reader (10) is capable of reading data from the tag (20) when the tag (20) passes the reader (10); and thereby communicating data from the tag (20) to the reader (10) downhole. Typically, the method includes programming the tag (20) and the reader (10) to communicate data by at least one of the following means: transitions between discrete frequencies; use of specific discrete frequencies; and length of time in which a carrier wave emits a specific frequency in preference to at least one other frequency.Type: GrantFiled: August 23, 2010Date of Patent: November 8, 2016Assignee: Petrowell LimitedInventor: Daniel Purkis

Patent number: 9115573Abstract: A method and apparatus for operating a downhole tool is disclosed. The method involves providing a conduit for the passage of fluid. The conduit includes at least one reader which can read data and is arranged for the passage of fluid. A downhole tool is coupled to the reader and has at least one tag capable of containing data. The tag is moved within the conduit and at least partially through the reader such that the reader can read data from the tag when the tag passes. This enables remote operation of the downhole tool. An antenna is provided for use in a downhole tubular. The antenna comprises a generally cylindrical housing and a coiled conductor located within a portion of the housing and separated therefrom by insulating material. The portion of housing has a greater internal diameter than an external diameter of the coiled conductor.Type: GrantFiled: September 22, 2005Date of Patent: August 25, 2015Assignee: Petrowell LimitedInventors: Daniel Purkis, Iain Morrison MacLeod

Patent number: 9103197Abstract: The switching device comprises an electronic switch (111) embedded within a downhole tool (100) and an activator (20) for remote switching of the electronic switch (111). The activator (20) may be a handheld unit that is used at the surface of the wellbore by an operator or may be a wireline run unit. The activator (20) permits wireless and contactless activation of the electronic switch (111) without the need for mechanical switches which could provide a point of failure for the downhole tool (100). The electronic switch (111) comprises an electronics module and a power source such as one or more batteries (126) wherein in the active configuration, the switch (111) can allow electrical connection between the electronics module and the power source (126) and in the inactive configuration, the switch (111) prevents electrical connection between the electronics module and the power source (126).Type: GrantFiled: March 6, 2009Date of Patent: August 11, 2015Assignee: Petrowell LimitedInventor: Daniel Purkis
