Well Swivel 00000

Welltec® Swivel

Introduction

The Welltec® Swivel is a sub that mitigates the torque from the wireline cable to be transferred to the downhole intervention tool allowing continuous tractoring. In addition, it provides live measurement of the tension level of the wireline on the cable head, allowing the operator to manage the risk of over-pull while keeping the wireline in tension during the operation.

Overview

With the hydraulically compensated Welltec Swivel, the risk of unintentionally wrapping the wireline cable due to torque build up through the toolstring is minimized. An integrated measurement of tension at the cable head is being sent to the surface continuously during an operation, providing live data which allows the operator to optimize downhole intervention tools functionality, such as tractoring speed, weight on bit for milling, etc. As well as allowing to manage the risk of over-pull while keeping the wireline in tension during the operation. The Welltec swivel with head tension integrates fully with Welltec equipment and surface read out and increases safety on the operations it is used in.
