About MeUltrasonic Transducer,
In 1988 the Ocean Odyssey drilling platform exploded killing the radio operator. The explosion occurred due to various human factors as well as an inability to control the escape of hydrocarbons to the surface via the borehole itself.
This ultrasonic Transducer was used in 1980’s/1990’s offshore. The hydrocarbons that the offshore industries produce are highly dangerous if not controlled. A release of gas or condensate could result in a catastrophic explosion, leading to death of the crew, destruction of the installation, as well as ecologic damage. Prevention of such releases is a primary concern of all those in the industry. This has led over the years to the development of sophisticated equipment to monitor the state of all aspects of the installations and processes. When drilling, mud is pumped down the well and a steel casing introduced. The ‘mud’ is a means of controlling the pressure of the encountered hydrocarbons so preventing their uncontrolled release which would cause a kick potentially destroying the installation. It also ensures that the cuttings (rock drilled out) are brought to the surface keeping the well clean and productive. The process is monitored using various remote sensors to ensure that the borehole itself is not fractured leading to a flow of mud into the reservoir to prevent pollution as well as rapid changes in pressure down the borehole.
This ultrasound transducer was used to monitor the condition of the borehole wall and the internal metal of the well.
