Overview

Rock Capillarity - CIR

About the Course

 Conventional reservoirs are covered in this course.

 The course covers in great detail how capillarity influences the distribution of hydrocarbons in reservoir rocks and how the strength of capillary forces can be utilized to infer important details about the features of rocks, such as pore throat widths, pore network geometry, porosity, and permeability. Numerous in-class exercises help students practice using capillary pressure data for reservoir characterization while reinforcing the material covered in the course. Spreadsheet software will be used to complete exercises on the computer.

Target Audience

 geoscientists, petrophysicists, reservoir engineers, and research and development personnel who aim to understand the capillary characteristics and hydrocarbon distribution in reservoir rocks at the fundamental and intermediate levels.

 Course Objectives

 Participants will pick up skills in:

•  For a certain set of outcomes, choose the right capillary pressure measuring technique. Set of mercury/air capillary pressure data closure correction
• Using the Thomeer, Leverett-J, and Brooks-Corey methods, fit and examine capillary pressure data. Identify the zone of interest's capillary pressure curves' representativeness Using a mercury/air capillary pressure curve, calculate permeability.
• Using a capillary pressure curve, determine the size of the pore throats.
• Create a fake capillary pressure curve, then use a petrographic investigation to determine the air permeability.
• Obtain interphase tension values.
• Hydrocarbon/water capillary pressure curves to mercury/air capillary pressure curves Find the distribution of saturation height in a rock with a single pore system or one with several pore systems.
•  find the water saturation that cannot be reduced Determine a transition zone's length
• Using partial penetration, forecast downdip water level Utilize the Klein-Hill-Shirley method to identify clay-bound water. Data from capillary pressure and NMR should be compared.
• Calculate the highest hydrocarbon column that a certain sealing layer can withstand without leaking.
