Abstract
An optical device (32) transfers an optical signal to or from an electronics unit (30) used in relation to downhole equipment of a drilling operation. The device includes a body (38) and an optical signal direction or light path altering means (40), the body having a light path arranged to allow the optical signal from a light source (16,18) associated with the electronics unit to pass to the optical signal direction altering means, the optical signal direction altering means arranged to cause the optical signal to change direction of travel within the body of the optical device.
Claims40
A device that transfers at least one electromagnetic signal to or from an electronics unit of downhole equipment, the device including a body and an electromagnetic signal direction altering means, the body having a light path arranged to allow the electromagnetic signal from an electromagnetic wave source associated with the electronics unit to pass to the electromagnetic signal direction altering means, the electromagnetic signal direction altering means causing the electromagnetic signal to change direction of travel, the device, in use, configured to transmit or receive the electromagnetic signal through at least one aperture through a side wall of a component of downhole equipment.
A downhole data gathering system, including a communication device arranged to communicate wirelessly with an electronics unit of downhole equipment, the downhole equipment including an electronics unit configured to obtain data relating to a borehole into which the electronics unit is inserted or to obtain data relating to equipment used within the borehole system, and a device that transfers electromagnetic signals to or from the electronics unit of the downhole equipment, the device including a body and an electromagnetic signal direction altering means, the body having a light path arranged to allow the electromagnetic signals from an electromagnetic wave source associated with the electronics unit to pass to the electromagnetic signal direction altering means, the electromagnetic signal direction altering means causing the electromagnetic signal to change direction of travel and wherein the device is configured to enable the electromagnetic signals to be transmitted to or received from the electronics unit whilst the electronics unit is connected to the downhole equipment, the device enabling transmission of the electromagnetic signals from the electronics unit to the wireless communication device, or from the wireless communication device to the electronics unit, through at least one aperture in a side wall of the downhole equipment.
