This is one of excellent VDO demonstrating shock and vibration in the drillstring by Schlumberger. In this VDO, you will learn about mechanisms of shock and vibration, types of whirls and how these will damage your drillstring and BHA. Moreover, we provide the VDO transcript to help you get more understand about the content of this VDO as well.
Full VDO Transcript
Vibration in drillstring is one of major downtime associated with drilling operation. Therefore, it is very important to learn and understand what each vibration mechanism is. This VDO created by Sperry Drilling Services well explains various of vibration modes that is happened downhole with the drillstring. You can watch the VDO here and we also provide full VDO transcription to help learns get more understanding about the content if the learners cannot catch all wordings from this VDO.

Ouija Board is a method that directional drillers use to calculate inclination and azimuth at the bottom or distance and tool face to drill at required direction. Figure 1 is an Ouija board.

Have you ever seen this VDO?
In the VDO, it stated that this was a false calculation which was result this directional drilling disaster. However, when we see this footage, we don’t really believe that this situation was happened for oil and gas drilling.
Magnetic and gravity tooสface are terms in directional drilling world to describe the direction of the well. They are different in meaning and application therefore this article will teach you about these terminologies and how to read it.
Magnetic Toolface
The magnetic toolface is an angle projection onto the horizontal plane between the tool face and magnetic north. Typically, directional tools use the magnetic tool face when the inclination is less than 5 degree. The Figure 1 demonstrates that the mud motor is lined up to kick off at 30 degree azimuth magnetic.
