    5.1 Making Connection with Top Drive while Drilling

    5.1.1 Once stand is drilled and the Top Drive is just above the drill floor. The Driller stop

    rotating, ease off on spin control to prevent backlash and pick up to ensure pipe is

    free. (back ream and wash as per requirements or Drilling Program). 5.1.2 The Driller lowers the string to the connection depth and upon the Driller’s

    instruction, the floormen set slips with Top Drive weight plus 2,5 tons (5 k lbs).

    Note: if Top Drive stalls while rotating, release torque carefully to prevent backlash. 5.1.3 The Driller stops pumping, bleed off any back pressure through the trip tank. 5.1.4 The Driller close the IBOP on the T D (the light will come on) visually check that

    the valve is closed fully.

    5.1.5 The Driller breaks the save sub connection with the Top Drive torque wrench by

    pressing and holding the torque wrench button until the top jaws stop turning,

    release the torque wrench (wait until the torque wrench is back to the rest position

    before attempting to rotate).

    5.1.6 The Driller locks the rotary table, switches the Top Drive to reverse and rotate out,

    keeping 2,5 ton (5 k lbs) overpull while rotating until pin end is out of box, stops

    rotating, switch the Top Drive to forward and unlock the rotary table. 5.1.7 If applicable, a Floorman removes the drill pipe screen, cleans and puts it in the

    drill pipe screen ring or basket mounted on the Top Drive.

    5.1.8 A Floorman applies dope to the saver sub pin.

    5.1.9 The Driller picks up the drill string with the elevators and lower the string to a

    manageable height for the floormen to stab in the next stand. Floormen set the slips

    and the Driller unlatches the elevators.

    5.1.10 The Driller engages the drawworks and raises the elevators of the Top Drive to the

    finger board (wait for the elevators to be about 3 m (10 ft) above rotary table before

    extending the link tilt for the derrickman), using the TV camera for viewing the

    Derrickman if applicable).

    5.1.11 Floormen are to prepare to tail the stand to the rotary table with a rope. Stabbing

    guide may be used if necessary.

    5.1.12 Derrickman latches the stand in the elevators and ensures that the safety latch is

    properly closed.

    5.1.13 The Driller retracts the link tilt and picks up the stand while the Floormen guide it

    over to the rotary table and the pin is doped.

    5.1.14 Floormen stab it into the joint in the rotary table.

     HSE operation procedure BHDC/SOP5-01 5.1.15 The Floormen position the break out tong on the box connection, ensure snub line

    is tight, tong must be at angle of >90 deg when torquing up the connection. 5.1.16 The Driller, with the “spin” switch, starts rotating while lowering the Top Drive

    over the stand. With the help of the TV camera (if applicable) lowers the saver sub

    into the box of the stand in the slips and makes up both the top and the bottom

    connections to full make-up torque.

    5.1.17 The Driller releases the torque wrench, switches over to drill mode and floormen

    remove the tongs.

    5.1.18 The Driller raises the string to allow the Floormen to pull the slips. The Driller

    notes the pick-up weight and establishes that the string is free.

    5.1.19 The Driller starts rotation, opens the I.B.O.P., and then engages the pumps and

    ensures that circulation is established.

    5.1.20 The Driller, after checking that the pump pressure is correct, lowers the string and

    resumes drilling as per the Drilling Program.

    5.2 Making Up of Single Joint from Mouse Hole While Drilling

    5.2.1 Once stand is drilled and the Top Drive is just above the drill floor. The Driller stop

    rotating, ease off on spin control to prevent backlash and pick up to ensure pipe is

    free. (back ream and wash as per requirements or Drilling Program). 5.2.2 The Driller lowers the string to the connection depth and upon the Driller’s

    instruction, the floormen set slips with Top Drive weight plus 2,5 tons (5 k lbs).

    Note: if Top Drive stalls while rotating, release torque carefully to prevent backlash. 5.2.3 The Driller stops pump; bleed off any back pressure through the trip tank. 5.2.4 The Driller close the IBOP on the T D (the light will come on) visually check that

    the valve is closed fully.

    5.2.5 The Driller breaks the save sub connection with the Top Drive torque wrench by

    pressing and holding the torque wrench button until the top jaws stop turning,

    release the torque wrench (wait until the torque wrench is back to the rest position

     HSE operation procedure BHDC/SOP5-01

    5.6.2 The Driller extends the link tilt and Floormen remove the elevators. 5.6.3 The Driller lowers the Top Drive until it is about 2 inches from the dolly track stops,

    ensures that the links are kept outside the link tilt arms while lowering the Top

    Drive. Note: The Driller can’t see the link tilt arms from the console,

    communication with Floormen is a must.

    5.6.4 Floormen (or Mechanic) remove the link tilt chains from the arms and secure them

    to the links (taped).

    5.6.5 Floormen secure link with an appropriate sling on the tugger line. 5.6.6 Floormen (or Mechanic) remove the bolt from link hook, pull up slowly with the

    air winch and the manoeuvre the link until it is off the hook.

    5.6.7 The Floormen lay out link.

    5.6.8 Repeat steps 5 to 7 to remove the second link.

    5.7 Changing Top Drive Saver Sub (6 5/8” REG)

    5.7.1 The Driller lowers the Top Drive, extends the link tilt, continues to lower the Top

    Drive until the bell guide is about 1 m (3 ft) from rotary.

    5.7.2 Floormen (or Mechanic or Driller ?) remove the bottom spacer clamp from the Top

    Drive torque wrench.

    5.7.3 Floormen (or Mechanic) move the torque wrench lever to the break position. 5.7.4 The Driller pushes and holds the torque wrench button. Hydraulic pressure should

    be set at approx. xxx bar (1100 psi ) to make up 4 ?” IF connection.

    5.7.5 The Driller increases hydraulic pressure slowly until the connection breaks,

    releases the torque wrench, waits until it comes back to rest and repeats, decreases

    pressure.

    5.7.6 Floormen (or Mechanic) screw out and remove the saver sub, clean the box end

    connection and apply 60% lead base drill collar dope to box and pin end. 5.7.7 Floormen (or Mechanic) screw in the new saver sub.

    5.7.8 Floormen (or Mechanic) move the torque wrench lever to make position. 5.7.9 The Driller pushes and holds torque wrench button, repeats until top jaws stop

    moving.

    5.7.10 The Driller observes pressure gauges and increases pressure until make up torque is

    reached (minimum; maximum).

    5.7.11 Once desired torque is reached and with torque wrench engaged, the Driller

    decreases hydraulic pressure to xxx bar (1100 psi), making up torque for 4 ?” IF

    connection, releases the torque wrench.

    Page 7 of 8

     HSE operation procedure BHDC/SOP5-01 5.7.12 Floormen (or Mechanic) install the spacer clamp. Note: If the saver sub is new,

    make and break the connection twice (clean and re-dope).

    NOTE

    Different Top Drive requires different procedure for changing Saver Sub, for example, for some type hydraulic Top Drive, the I-BOP cam sleeve and cam have to be removed, and the I-BOP cylinders to be swung out before changing Saver Sub. Company may need to update this procedure based on the type of Top Drive used.

    6 Close-out

    Changing of saver sub and link must be reported in the daily drilling report and in the Driller’s tour book.
