EXAMPLE WELL KILL CALCULATION

This example is based upon the following situation: nnn

floating rig diverter system

TD 12 u00bdu201d hole

13 3/8u201d shoe depth

Water depth

RKB-sea level

Drill pipe

Drill collars

0.0049 bbl/ft

1097 psi

Company policy is to keep the choke and kill lines full of seawater to avoid settling.

A kick is taken and the well is correctly shut in and the pressures recorded. There is no Float in the string.

The choke line pressure drop is known to be as follows (with 13.0 ppg mud).

3.5 bbl/min

The recorded slow circulating rates down the pipe and up the riser are:

3.5 bbl/min

800 psi

NOTE: CLFL = Choke Line Friction Loss
