This 1-hour training first introduces the flow behaviour and type of pressure response for several types of wells, including horizontal and frac wells. Then deconvolution is defined with its benefits and limitations. the 2nd part of the training shows a “live” exercise using a well test program on how to recover a reliable deconvolved response from the data and how to use it to improve the understanding of the pressure response.

Training Objectives

What are the training objectives ? 
The main objectives are to:
  • Build on the “Well Test Theory and Practice” and visualize the well flow behaviour with the derivative plot
  • Understand deconvolution, its benefits and limitations,
  • Be able to recover a reliable deconvolved response and use deconvolution in a well test analysis
 

Agenda

What will be covered ? 
After a quick refresher on the “Well Test Theory and Practice” course, the  flow behaviour and type of pressure response are shown for several types of wells, with some examples. Then the fourth well testing tool, i.e. deconvolution, is presented as well as its benefits and limitations. Some techniques are explained on how to recover a reliable deconvolution for the analysis of the pressure data. The 2nd part of the video shows a “live” exercise using a well test software for an appraisal well. A reliable deconvolution is derived and used to improve the understanding of the response and perform well test analysis
The areas covered are:
  • Quick recap of the Well Test Theory and Practice
  • Type of pressure response for several types of wells (limited perfs, horizontal, frac)
  • Definition of deconvolution and its benefits
  • Conventional versus deconvolved derivative
  • Limitations of deconvolution
  • Validity of deconvolution: recover a reliable deconvolved response
  • References
  • Case Study with software: contribution of deconvolution in the well test analysis of an appraisal well
