Cameron installs world's first deepwater scale squeeze using MARS
Chevron has completed its first deepwater scale squeeze treatment using the Cameron’s MARS (Multiple Application Re-injection System), on well LDN4 in the Lobito Tomboco field, Angola.
HOUSTON -- Chevron has completed its first deepwater scale squeeze treatment using the Cameron’s MARS (Multiple Application Re-injection System), on well LDN4 in the Lobito Tomboco field, Angola.
The MARS system can be described as "a USB port for wellheads" and has previously been used for BP and Total for deepwater subsea pumping and metering projects. The MARS system, previously used for chemical injection operations by Shell in North Sea, has now been extended for deepwater scale squeeze operations up to 600 m (1,969 ft) with further plans for extending the technology to 1500 m (4,921 ft).
Chevron will use this system on 13 specially modified wells within the same asset to maximize production throughout the life of field. The total scope of supply from MARS-PS included the deployment and chemical handling interfaces in addition to the MARS hardware.
Roger Bradley, Subsea Superintendent for Chevron says, "The ability to use this technology in deepwater has a significant impact on our ability to undertake subsea well scale squeezes to mitigate scale formation from a MSV support vessel, and allows us to undertake the work without the use of a drilling rig."
Ian Donald, VPof MARS Production Systems adds, "The Lobito Tomboco project is our largest export order to date and confirms the MARS systems ability to provide cost effective deepwater liquid intervention from a MSV vessel. We are pleased to be working alongside with Chevron on such a high profile project and delighted they have chosen MARS as part of their production optimization strategy."
