Halliburton makes splash in deep water saving operator USD 1.2M

Challenges

An ultradeep, ultrahigh-pressure well in a deepwater environment posed challenges for data acquisition and tool conveyance.

The operator wanted to:  

• Perform formation testing services  
• Recover a high rate of quality rotary sidewall cores  
• Acquire high-quality VSP data and time-depth measurements  
• Minimize sticking risks and cable damage 

Solutions  

Halliburton had confidence that its industry-leading technology could acquire the data and provide the necessary solutions. Key technology included the Reservoir Description Tool (RDT™) technology for fluid sampling, the  Xaminer® Coring Tool for core retrieval, 5 x 30,000-psi DeepSuite™ receivers with quad-pack geophones for borehole seismic data acquisition, Super Combo Unit, derrick-mounted 18,000-lb Powered Capstan, 35,000-lb PowerPull™ cable, Releasable Wireline Cable Head (RWCH™), and the LockJar^® system for successful conveyance.

Results  

Halliburton ran its unique integrated solution to successfully acquire all required data safely and efficiently, while minimizing HSE exposure and operating expenses, saving the operator USD 1.2 million in rig time.

• The acquired sidewall cores were the deepest, highest pressure cores ever cut in Halliburton history with over 88% core recovery.
• The RDT formation tester successfully captured the deepest sampling and pressure readings ever taken by Halliburton.
• Halliburton provided excellent VSP data where the competition was unable to retrieve similar quality VSP data in nearby offset wells.
• The conveyance system reduced HSE exposure to personnel and prevented damage to the cable and tools.
