A drilling spool is the necessary equipment used to join other tools during the drilling procedure. It functions as a “master valve” to regulate the passage of fluids (e.g. oil and gas) during drilling. The drilling spool is an ideal choice to make sure the drilling machinery functions properly and safely.
A properly constructed drilling spool is imperative to the success of the drilling procedures. A good drilling spool can keep leaks and spills from occurring which are damaging to the environment and dangerous to the workers on the rig.
An well-engineered drilling spool is also essential to preserving the well bore and facilitate a smooth drilling operation. A nonoperating drilling spool can slow or shut down drilling, resulting in downtime and possible risk.
A drilling spool facilitates operations of the rig, as it acts as a point where the flow of fluid used in drilling can be controlled in one location. This enables rig workers to easily oversee and adjust the flow of oil and gas flowing from the well to the rig, dissipating complications and unsatisfactory performance in the drilling process.
A drilling spool also substantially reduces the possibility of any leaks, or without limitation any spills, from the hole, by incorporating means for sealingly connecting various tools together. This is also friendly for the environment and makes rig workers safe.
The casing head supports the weight of the casing and provides a pressure-tight connection with the wellhead. The tubing head, meanwhile, also supports the tubing string and controls the production flow of fluids. The gate valve controls the liquids along the drilling spool.
A good drilling spool is also able to enhance efficiency of the drilling process by simplifying rig activities and reducing non-productive time. This saves both time and money knowing that the drilling process is done as promptly as possible.
