The Driller’s Method

During drilling operation of oil wells, there may be inflow of formation fluids into the well, which is an undesirable condition. The driller should detect such events and closing the well immediately. Record information after the closing of the well corresponding to stabilization of pressure, volume gain, SIDPP (Shut-in Drillpipe Pressure) and SICP (Shut-in Casing Pressure. In the case of operations on floating units (subsea stack), this term could be redefined as Shut-in Choke Pressure).
The control method to be applied is the driller’s method. That is to circulate the influx even with the original weight of the mud, keeping constant the circulation pressure named ICP – Initial Pressure Circulation. The second circulation should be made with the kill mud weight in two steps:
1. Fill the drill string until the bit by keeping the pressure at the Choke (at the KILL, on subsea stack) constant and equal to SIDPP.
2. Complete circulation of the annular to the surface keeping the pressure of circulation with the kill mud constant named FCP – Final Circulation Pressure. On subsea stack, after the choke fully open, the pump pressure increases until FCP 2.

Attention: about drill bit off bottom

This method should only be applied with the drill bit in the bottom hole or when the kick is completely in annular of the drill string. To minimize errors of calculation of the kill mud weight, the calculations made in this application considers the depth of the drill bit instead of the depth of the well to calculate the kill mud weight.
The formation pressure consider the depth of well. In case of top of the kick bellow the bit, it is recommended to apply the volumetric method until kick go through the drill bit to the annular, following then the driller’s method.

Formulas:

ICP = Pks + SIDPP

  ICP =  Inital Circulation Pressure, psi
  Pks = Recorded pump pressure at the kill rate speed, psi
  SIDPP = Shut-in Drillpipe Pressure, psi

  Notes about floating units:
     a) Pks must be recorded by circulating riser;
     b) Record the friction loss in the choke line at the kill rate speed, psi;

KM = OM + SIDPP / (0.052 x TVD)

 KM = Kill Mud Weight, ppg
 OM = Original Mud Weight, ppg
 TVD = True Vertical Depth, ft

FCP = Pks x KM / OM

   FCP = Final Circulation Pressure, psi

FCP 2 = (Pks + ΔPcl) x KM / OM

   FCP 2 - Final Circulation Pressure with Kill Mud at Choke, psi
   ΔPcl - Choke Line Friction, psi

 

Summary of method

STEPS PUMP PRESSURE KILL PRESSURE CHOKE PRESSURE VOLUME TO PUMP
Bring the pump to kill speed SICP SICP – Choke line friction loss
Circulate out the influx to surface ICP Bit to Surface
Circulate to fill drill string with kill mud SIDPP SIDPP – Choke line friction loss Surface to Bit
Circulate to fill annular with kill mud FCP Bit to Surface
