What is drill-stem Testing (DST)?

One of the most important stages of completing a well is discussed in this report which is the Drill-Stem Testing (DST). This report discusses three main aspects of this technique, it indicates the detailed function of each component of the tool assembly. Then it discusses the required decisions to be made to perform a test.

How to perform drill-stem testing?

The simplest way to describe the process of Drill-Stem Testing is to present a typical DST pressure chart of an open hole, see figure (10) and describe each segment of it. When all the factors for performing a DST are taken in consideration as mentioned in the previous section, the plan for the DST is ready to run.

How many indenters are used in a full hole drill?

Also, all drilling in this study is full hole drilling and conducted by one drilling machine with the same DTH hammer and drill bit. The bit wear of the 16 semi-spherical indenters is insignificant and its effect is negligible since the total length of the six drillholes in this study is about 60 m.

Can a drilling process be used as a geotechnical testing method?

If the drilling data can be collected and analyzed properly, the subsurface geomaterial can be profiled based on their strength difference. Hence, there is a potential to use the drilling process as an in situ testing method for geotechnical investigation.
