Stripping with Volumetric Control Steps and Example Calculations

This example demonstrates the calculations and the steps of the stripping with volumetric control so it will help you understand about what calculations required are and how to perform the stripping with volumetric control.

Practical Considerations for Stripping Well Control Operation

This section will discuss some practical stand points of the stripping operation with and without volumetric control. Additionally, this will summarize some key points for both methods of stripping for off bottom well control.

General Practical Considerations

Stripping operation requires accurate measurement of fluid bled off therefore it is very critical to have a small trip tank or a stripping tank for the operation. Furthermore, when the drillstring is stripped deeper, you might need to fill the pipe. You need to ensure that the volume filled up will not create any confusion with the bleed of volume. There are some cases when personnel don’t track the volume properly and finally the kick is unintentionally introduced into the wellbore. Continue reading

Stripping Procedure without Volumetric Control for Non-Migrating Influx

This article will teach you about the stripping procedure for non-migrating kick. This procedure is used to strip to desired depth but it won’t account for volumetric bleed therefore it is mainly applicable for stripping with non-migrating kicks as water or oil.

Basic Understanding of Stripping Operation Well Control with Gas Influx

In the previous articles, we discuss about the stripping operation and techniques with non-migratable kicks as oil and water kick. This article will focus on the stripping operation with gas influx and we are going to describe some additional considerations that you need to account for. Gas kick is different from the liquid kicks because gas can naturally migrate. The gas migration affects the stripping operation because increase in casing pressure due to gas migration must be taken into considerations.
