Block 3/29a was awarded to BP (50%) and NIOC (50%) as a 4th round licence in March 1972.
RHUM gas and condensate field lies in block 3/29a. It is located 380 km NE of Aberdeen and 44 km N of the Bruce platform in the mid North Sea. The field is a high pressure, high temperature (HP/HT) reservoir, with pressure of up to 12,000 psi and temperatures of 150°C with recoverable gas reserves of 23 billion cubic meters (800 billion cubic feet).
RHUM has been developed via a multiphase, high pressure production line tied back to the Bruce facilities.
The RHUM gas and condensate field development is a high pressure, high temperature (HP/HT) reservoir, with pressure about of 12,000 psi and temperatures of 150°. Overcoming the HP/HT issue was a major challenge and strategically important for future North Sea HP/HT gas condensate discoveries. RHUM is the first BP/IOC HP/HT development with subsea High Integrity Pressure Protection System (HIPPS).The High Integrity Pressure Protection System, located subsea at the production manifold, consists of three pressure transmitters, voting logic and two high integrity fully rated isolation valves.
There is an electro hydraulic chemical control umbilical from Bruce to the manifold and from the manifold to each tree.
As well as transfer of control signals, the umbilical is also used for chemicals supply and power supply to the field.
