Halliburton
deploys largest-ever coiled tubing intervention system for deepwater
Gulf of Mexico operations
Posted: 28 May 2003
Halliburton recently demonstrated a new, massive coiled tubing
intervention system at its New Iberia, Louisiana, Training Facility.
The system, which includes the largest, most powerful, and strongest
components ever deployed, consists of Halliburton's V135HP coiled
tubing injector, a reel capable of handling 36,000 feet of 2-3/8-inch
coiled tubing, and a 750-ton capacity tension lift frame.
The coiled tubing string, which will be the longest ever deployed,
is constructed of 120,000 pounds yield strength alloy steel making
it the strongest ever built. The lift frame is twice the size of
normal lift frames.
Designed for high pressure, high temperature (HPHT) operations,
the intervention system is headed for BP's Thunder Horse development
in the Gulf of Mexico.
It will be used primarily during the completion phase of the wells
for operations such as fill removal, fluid swap, milling, backup
for e-line perforating, fishing, jetting, plug retrieval, and tubing
cuts.
To add to the efficiency of intervention operations, the tension
lift frame is equipped with a track that enables moving the injector
without completely rigging down in order to quickly change to wireline
operations.
Located in the deepwater Mississippi Canyon area, the Thunder Horse
project is in over 6,000 feet of water, the limit of current subsea
production technology. Well depths may exceed 30,000 feet measured
depth.
The water depth combined with well depth necessitates the high
capacity equipment. Specifications of the system include 15,000
psi working pressure; 135,000 pounds pull rating; zone 2 power package;
5-1/8-in. 15,000 psi, H2S rated BOP; air-purged zone 2 operator's
cabin and electronic data acquisition system.
"This technically advanced, record-size coiled tubing equipment
is the result of our continuing commitment to helping operators
meet the challenges of deep water operations and improve return
on investment on their projects," said David King, senior vice
president, Halliburton's Energy Services Group.
Currently contracted to BP, under certain circumstances the coiled
tubing equipment can be deployed for other operators. Halliburton
expects to have another similar system ready in the near future.
