Course Description:

The benefit of this course is triple. First amont the upcoming categories of courses (Advanced,Theoretical, and Applied) this one is Applied. Second, it is based and built upon a real Case Study.Third, it applies to an increasingly important part of the hydrocarbon reserves , unconventional reserves in this case Tight Gas.

Key Points:

  • Case Study:Re-interpretation of Well test results in Tight Gas sandstone for an Exploration project.
  • Detailed analysis of Flow periods in DST (Tight formation,Low reservoir pressure)
  • Review of DST characteristics on specific Tight gas fields.                       

Preliminary Resources

Step 1: Read the following Context Explanation:

The course shows typical real life examples of elements to understand and solve based on a typical Exploration project of a field renamed ''ALPHA'' and  located in North-Africa. The field is a Tight gas field , and the formations are Devonian formations with permeabilities between 200-300 mD, and Ordovician formations with heavily cemented Quartzite sandstones with average permeability ranging from 0,01-0,1-1 to 10mD up to 50 mD.

Step 2: To help get you started, it is recommended to view the following video on Pressure vs. time on a typical DST:

Pressure Transient Analysis

Very Good course! the Lecture gives a sound approach of practical situations for the beginner or experienced well test interpreter...One of the few focalizing on Unconventionals such as Tight Gas and Oil sandstones...
