This section describes the procedures and practices that should be considered during the design phase of the casing to ensure that the casing performs as per design and the overall life cycle well cost is minimized.

- ordering casing;
- storage, handling and transport of casing;
- preparation of casing prior to running;
- running and testing casing;
- condition monitoring of installed casing.

Ordering casing

Ordering casing

Casing is one of the most critical well consumables with respect to timing. Total elapsed time for procurement of Oil Country Tubular Goods (OCTGs) varies from 6-18 months. This includes tendering…

Monitoring Casing Condition

Once a casing string has been successfully cemented in place and tested, subsequent operations must be planned to ensure that the casing remains fit for purpose. Condition monitoring systems should be…

Running and Testing Casing

Running and Testing Casing

To ensure that the casing is run efficiently to the correct depth and in the desired condition, specific equipment and techniques should be considered in the design phase.

Preparation for Running Casing

Preparation of casing before running serves two purposes. 1. ensure that the pipe body and threads are adequately protected from possible damage when being moved to the drill floor. 2. ensure that…

Casing Storage, Handling and Transport

This article describes the recommended guidelines for casing storage, handling and transport that need to be taken account in the design phase of the casing.

1 Storage

The design of pipe racks is…
