Baker Hughes Leading Technologies are Critical to Success of Deepwater Project

• Dynamic Kill Drilling – an innovative riserless drilling technique – was used to batch drill and set 20" casing in 15 wells from the subsea template. A record 193,110 barres of DKD fluid were deployed from our Port Fourchon facility.
   
• RHEO-LOGIC constant-rheology drilling fluid was used to reduce fluid losses by 91% compared to previous wells.
   
• LWD density and gamma ray borehole imaging and while-drilling pressure measurements enabled hazard mitigation, precise well placement, and accurate formation evaluation.
   
• The AutoTrak rotary steerable system and CoPilot drilling optimization service were used in 14.5" X 16.5" hole sections, to perform reaming while drilling and directional work in laminated sand/shale formations. This hole section was drilled in one run on five consecutive wells.
   
• Genesis PDC bits, designed specifically for this project, reduced vibration while drilling interbedded sequences with expandable reamers.
   
• Baker Hughes completion tools include Neptune Safety Valves, the CK Frac system for sand control, and Intelligent Well Systems to adjust flow without intervention.

PDC Bits and Integrated Drilling/LWD Systems Access Deepwater Reservoirs

Baker Hughes is providing ongoing directional drilling, LWD and Reservoir Navigation services for deepwater horizontal wells, including pre-salt plays. PDC bits, integrated bottomhole assemblies – with rotary steerable systems, logging measurements, imaging, formation pressure testing and drilling dynamics sensors – are drilling complext well profiles and long horizontal sections. Reservoir Navigation services use real-time measurements to guide the well path, keeping it in the most productive part of the reservoir. On a recent well, the horizontal section was adjusted eight times to stay in the pay and extend the later 67% farther than the original plan. Another geosteered well was drilled in two runs (compared to five planned) and placed more than 2700 ft of hole in the productive zone.

Innovative ESP Systems Boost Subsea Production

Baker Hughes has been an innovative supplier of Electric Submersible Pumping system technology for subsea applications in Brazil’s deepwater fields. We have provided subsea booster systems, variable speed drive technology, and the first subsea ESP system used to produce heavy oil.

Permanent Monitoring Installed in 100 Deepwater Wells

Since 2003, Baker Hughes has installed permanent monitoring technology in 100 wells in the Kizomba project, including 158 Dual Star gauges rated to 10,000 psi and more than 500 miles of control lines.

Drilling and Evaluation Services Reduce Costs and Improve Efficiency

After comprehensive pre-well planning, Baker Hughes provided drill bits, directional drilling, drilling motors, rotary drilling systems, surface logging and LWD imaging, acoustic and pressure testing services. This technology package improved wellsite safety, drilling efficiency and target accuracy on complex 3D wells, while drilling nearly 500,000 ft of hole.

Four Wells Drilled and Evaluated 23 Days Ahead of Plan

Baker Hughes helped an Australian operator mobilize to West Africa to drill a four-well exploration/appraisal program in a frontier area. Services included project management, drill bits, wireline logging, directional drilling, LWD, coring, drilling fluids, packers and well screens. Equipment and personnel were mobilized from Europe, Angola and the USA. The project was completed successfully in 102 days, 23 days early and 22% below AFE.

Interventionless Packer Setting Saves $35 million

The Baker Hughes SB/3H Interventionless packer setting mechanism saved $35 million for the operator by reducing operational risk and saving rig time. The remotely set mechanism, rated at 10,000 psi and 350°F, saved an estimated $1 million per well on 35 wells in the field.

High Performance WBM Protects Hole Through Typhoon Delay

PERFORMAX HPWBM was applied to drill 12-1/4" and 8-1/2" sections of an exploratory well. The system achieved excellent wellbore stability without bit balling or drill string accretion. When a typhoon approached, the hole was left open for 21 days during the evacuation. Drilling resumed without problems and all drilling, coring, logging and casing objectives were met.

High Performance WBM Meets Environmental and Performance Objectives

PERFORMAX HPWBM was used to drill 12-1/4" and 8-1/2" sections in an exploratory well as an environmental alternative to SBM. The 12-1/4" section was drilled with a PDC bit in one run. ROP exceeded expectations with excellent wellbore stability.
