Well Kicks Guide While Drilling Oil & Gas Wells
1) OBJECTIVES

The objectives of this section are to Highlight the Causes of Kicks and Influxes.

Primary control is defined as using the drilling fluid to control formation fluid pressure.  The drilling fluid has to have a density that will provide sufficient pressure to overbalance pore pressure. If this overbalance is lost, even temporarily then formation fluids can enter the wellbore. Preventing the loss of primary control is of the utmost importance.
