WELL CONTROL KICK SHEET (SUBSEA ONLY) Pressure Step Down Chart 1) Calculate I.C.P. 2) Calculate F.C. P. 3) Calculate Step-down. 4) In the left column record strokes in 100 stroke intervals, ΔP x 100 until final circulating pressure is reached 5) Record I.C.P. in top right column, and deduct the pressure step down Δ down ΔP P until F.C.P. is reached (psi/100 stks) 6) Calculate adjusted choke line friction (using Kill Mud).
