Kick

Kick

The "kick" is an undesirable flow of formation fluid into the wellbore. It is one of the drilling problems that may suddenly turn into a disaster if it is not controlled.

1. Introduction

The kick phenomenon is an undesirable phenomenon during the Drilling Operations. The reason is that we are not prepared to receive the pressure that comes out of the Formation, which mostly accompanied by water, gas or oil. But the occurrence of this flow during the production process may be desirable, as in this case we are prepared to receive any flow from the Formation.

2. Causes of kick

A kick occurs when the Hydrostatic Pressure is less than the Formation Pressure.

The reasons behind this are:

• 75% of kick occurs during Tripping.
• The failure to keep the hole full of mud.
• The increasing in pit volume, mud pit volume should remain relatively stable during Drilling Operations.
• The increase in Rate of Penetration (ROP)
• Decrease in Mud Circulation Pressure
• ncrease in Chloride Concentration
• Swabbing and Surge
• Low Density Fluid
• Abnormal Pressure
• The Crew Errors

When do I know if there is a kick?

• If the incoming Mud Barrels are less than the Outgoing Barrels from the well, or if there is an increase in the number of Barrels in the Mud Tank.
• Increase in (ROP)
• Increase in Volume of Cuttings

Methods to control the kick if it happens

1. Primary control: In this method we increase the hydrostatic pressure by increasing the Mud Density.
2. Secondary control: If the 1st method didn't succeed, I could use the 2nd method, which is to Blowout preventer (BOP), which shuts off and kills the well completely.

Once kick occurs, the well should be Shut in and a killing operation is carried out to prevent further development of Blowout.

How to avoid the kick?

• Mantian Accurate Trip Sheat
• Great concern while POOH Wet Trip
• Great concern while POOH with Drill Collar
• Great concern while RIH with Casing
• Caculation of Pressure Drop perfect
