Thick-Walled Cylinder

Thick-Walled Cylinders Measure Expelled Fluid to Sense Changes in Internal Wellbore Volume Increase Confining Pressure to Simulate Drawdown/Depletion/Underbalance Thick-Walled Cylinders Measure External Strain Geometric Analog Internal Monitoring Is Essential

This figure shows the two basic measurements made during the thick-walled cylinder testing. These are the volumetric strain sensed at the outer boundaries of the cylinder and the fluid expelled from the central wellbore (indicating changes in dimensions of this inner wellbore analog).

This figure shows the methodology for estimating the initiation and accelerated deformation from the volume of fluid expelled from a central wellbore during the thick-walled cylinder testing. Log-log plotting is used to emphasize inflections
