Well Test Analysis

Course content:

The main goal of the course is to train students to determine the reservoir properties and production capabilities of wells by means of standard computer programs used in petroleum and geoenergy industries. The well test analysis is based on the theory of fluid flow in a porous medium with the aim of determining the basic reservoir characteristics and hydrodynamic connections between the parts of the reservoir, necessary for the exploitation of oil, gas and geothermal field. Well tests are performed by causing fluid inflow into the well and its closure, and by measuring the consequences of such procedures on the pressure data response. Dynamic analysis of this data is necessary for monitoring production parameters and full reservoir engineering, as well as for its successful business management.

Course objective:

  • Introduction to well test analysis
  • Pressure Transient Analysis (PTA)
  • Rate Transient Analysis (RTA)
  • Methods for pressure build-up and drawdown test analysis
  • Applied analytical models for pressure analysis in software package Kappa Workstation (programme Saphir and Topaze)
  • Applied numerical models for pressure analysis in software package Kappa Workstation (programme Saphir and Topaze)
  • Reservoir models for pressure analysis cases with deviations from ideal conditions due to wellbore dynamics
  • Analysis of the pressure behaviour in vertically fractured wells, horizontal wells and in MFHW (Multy Fractured HW)
  • Analysis of wells in a Bounded drainage area (Semi-steady state) and in Constant pressure boundaries (Steady state)
  • Reservoir limit test and Interference test
  • Analysis of the pressure during the multiphase flow in the reservoir
  • Gas well testing (isochronal and modified isochronal test)
  • Well test analysis in reservoirs for underground gas storage
  • Digital connection of data analytics to production and reservoir models (intelligent systems)
  • Other test operations (DST-Drill Stem Testing)

Learning outcomes at the level of the course:

  • Define the theoretical concepts and industry standards for data analysis and interpretation of the well test results;
  • Select well candidates and to determine test objectives in oil, gas and geothermal reservoirs;

  • Analyse the pressure behaviour of fractured, horizontal and multiple fractured horizontal wells in oil and gas reservoirs;
  • Evaluate reservoir properties for underground gas storage by applied well test analysis;
  • Apply applications for digital connection of data analytics to production and reservoir models.
