What is open hole logging?

Open-hole logging refers to logging operations that are performed on a well before the wellbore has been cased and cemented. In other words, the logging is done through the bare rock sides of the formation.

What is open hole completion?

Open hole completion means that the oil reservoir is completely exposed during completion of a straight or horizontal well. There are two types of procedures for open hole completion. After drilling to the top of the oil reservoir, the intermediate casing is run in and the well is cemented.

What are the different types of well logging?

Well Log Techniques

• Acoustic Logs. Cement Bond Log. Cross-Dipole Acoustic Log.
• Caliper Log.
• Chemical Logging.
• Density Log.
• Gamma Log.
• Image Logs.
• Mud Logging.
• Neutron Log.

What is Casehole?

A cased hole is the part of the wellbore with metal casing and cementing. A cased hole is in contrast to an open hole and is one in which casing has been run and cemented. In a cased hole, casing is run and cement is circulated. A cased hole is the part of the wellbore with metal casing and cementing.

Is there a course for open hole logging?

This course is covers the whole range of Open Hole, Cased Hole and Production logging tools and their applications. This is a wide ranging course that effectively covers all the logging techniques both Open Hole and Cased hole. The course starts with an overview of the reservoir rock properties and reservoir fluids.

What is the procedure for open hole wireline logging?

OPEN HOLE WIRELINE LOGGING Suggested procedure: 1. Read through the remainder of this section a find out how to process each log. Each log from the composite panel (previous page) is described seperately. 2. Working on the log panel use a combination of lithology and permeability indicators to identify the potential reservoir intervals.

What can open hole and cased hole be used for?

Log interpretations, both in open hole and cased hole, has applications to all branches and disciplines of the oil and gas industry. The workshop will also benefit geoscientists that are newcomers to the oil and gas industry. It will provide a foundation for future reference.

How is logging done in a well formation?

In other words, the logging is done through the bare rock sides of the formation. This is the most common type of logging method because the measurements are not obstructed and it’s done during or after the well has been drilled.
