The Relevance of the Most Irrelevant BHA and Drillstring Component (Why I decided to mess with the conventional blade stabiliser) Tom Newman March 10 th 2016
BAT-2 Downhole Dynamics Vibration Related Issues Directional Problems Poor BHA response, energy transfer & MWD Interference BHA Damage MWD/LWD, PDM, RSS failures, excessive stabiliser wear Poor Hole Quality Poor energy transfer, trip time (ledges), csg running issues
Whirl as Shape Is a sine wave Bit tilted by wave, reduces ROP & increases MSE Shape crosses wellbore = quiet (nodes) Mechanical Specific Energy best indicator Source: Fred Dupriest, Thus the Lowly Stabiliser
Fit for Purpose?
Fit for Purpose Solution?
Poor Hydrodynamic Design
Static Flow Modelling Research
Rotational 100 rpm Flow Modelling Research
Switchblade Enhanced Hydrodynamic Weight Stabiliser Design Transfer
Retention Method Research
Test bolts Test bolts Test blade Pull and push
Final Retention System An integral, interference fit pin, with precision radii and a locking bolt array
Run History Wells drilled Hours drilled Meters drilled 20 > 7,000 hrs > 56,000m / 183,000ft Run in Dutch North Sea, UAE, KSA, France, Turkey, and Belgium Less balling up, stick/slip, vibration & little wear with more stable torque. All other BHA components in good condition.
Case History: Weight Transfer & Less Balling Dutch North Sea OBJECTIVE: 16" hole section 659m - 1,566m Motor BHA (1.15 ° ABH) + 2 x Switchblades 15" & 15 ¼" Build to and hold @ 25˚ inclination CONCERNS: Packing off Balling
Case History: Weight Transfer & Less Balling DRILLING OBSERVATIONS: No motor stalls No hanging up Good tool face control POOH OBSERVATIONS: No clay ball problems No packing off
Fixedblade Known gauge ODs Tangent sections Lower cost applications
Case History: Weight Transfer & Less Balling Western Gulf Region OBJECTIVE: 8 1/2" hole section 6,428ft – 9,598ft Motor BHA (1.50 ° ABH) + 1 x Fixedblade 7 7/8" (8") Hold horizontal with azimuthal left turn @ 27˚ CONCERNS: Sliding ROP Torque levels
Case History: Weight Transfer & Less Balling Run Results (Spiralblade vs. Fixedblade) Backflow induced packing off (L0 above) Minimal surface weight transfer / hang up POOH No motor stalls
