Coiled Tubing Applications Training Course

Introduction:

Coiled tubing (CT) has many applications within the petroleum industry, including drilling (CT drilling), cementing, wellbore cleanup, oxidizing, and hydraulic fracturing. In contrast, excessive frictional pressure loss, due to the relatively small tubing diameter and the curvature of the coiled tubing (which is thought to be secondary to the flow), often restricts the maximum achievable fluid injection rates. Therefore, it is of practical importance to study the flow regularity and friction properties in coiled tubing operations.

A comprehensive look at coiled tubing components, tools, and the breadth of operations possible with this technology. Participants will learn about the tools that make coiled tubing operations successful and the essential components that ensure the tubing withstands the harsh conditions of the oil and gas environment.
