Accepted items procured before April 1, 2000

Shell/ Anadrill/ 003 Richard Hailes, Shell Expro Shell Expro UESM Mobiles/ Anadrill Variable gauge stabiliser, Fluid Hammer Lot numbers numbers not specified on individual component. Lot numbers are traceable through unique serial numbers Accepted
Shell/ Anadrill/ 004 Richard Hailes, Shell Expro Shell Expro UESM Mobiles/ Anadrill Powerdrive Rotary Steerable Bias Unit and Control unit bevels not within NS-2 tolerances. For bevels to meet, ODs of 2 items would need to be different, exposing the face seal of one item to the annulas Accepted
Shell/ Anadrill/ 005 Richard Hailes, Shell Expro Shell Expro UESM Mobiles/ Anadrill Bent Subs No SRG in pin end. The angle of the pin prohibits cutting of the SRG Accepted as Limited Service
Shell/ Anadrill/ 006 Richard Hailes, Shell Expro Shell Expro UESM Mobiles/ Anadrill Near Bit Subs No bore back in box ends. Length prohibits the application of bore back without making tool to long for directional drilling purposes Accepted
Shell/ Anadrill/ 007 Richard Hailes, Shell Expro Shell Expro UESM Mobiles/ Anadrill Near Bit Stabilisers No bore back at bit end. Bit end bored for float, can not match BSR without reducing OD of stabilisers severely Accepted
Shell/ Anadrill/ 008 Richard Hailes, Shell Expro Shell Expro UESM Mobiles/ Anadrill Powerplus & impulse MWD/LWD No SRG or bore back. ID too large to apply SRG or bore back. Large ID allows tools to be secured inside collar Accepted
Shell/ Anadrill/ 009 Richard Hailes, Shell Expro Shell Expro UESM Mobiles/ Anadrill Driveshafts on all Powerpack mud motors No SRG or bore back. Application of SRG or bore back would lengthen shaft and increase susceptibility to failure Accepted
Shell/ Anadrill/ 010 Richard Hailes, Shell Expro Shell Expro UESM Mobiles/ Anadrill Rocky back stabilisers No SRG or bore back. Stabiliser too short to conform to minimum fishing dimensions Accepted
Shell/ Anadrill/ 011 Richard Hailes, Shell Expro Shell Expro UESM Mobiles/ Anadrill Mud motor internal connections, e.g. ACME threads No SRG or bore back. ID of stator tube housing too large to allow SRGs or bore backs Accepted

BSRs outside recommended range Accepted
Talisman/ Anadrill/ 004 Kevin Fearnley/ Fearnley Procter Group Talisman/ Anadrill 6" Hydraulic Adjustable Stabiliser Client third party inspector to verify on load-outs that this tool configuration is to be used in "near bit" BHA setup.

Talisman/ SPS AFOS/ 005 Kevin Fearnley, Fearnley Procter Group Talisman/ SPS AFOS MFCT Clutch Type The MFCT does not have the conventional stress relief features machined to pin and box. Although this tool is classified as non-drilling it still sees stress rotation, albeit is low cyclic stress and its inspection frequency is very routine. Exception is issued on the following: Thread roots are cold rolled after machining (this should be documented in tool history file). Client third party to witness MPI of connections or to verify suppliers inspectors are competent and certified. Accepted
