This article explores the features, benefits, and applications of these advanced rigs, highlighting their contribution to enhancing efficiency and safety in oilfield operations.

Enhanced Mobility and Self-Propulsion

Heavy-duty self-propelled workover rigs are designed with mobility in mind. Equipped with powerful engines and rugged chassis, these rigs have the capability to traverse challenging terrains on their own. They eliminate the need for external transportation and positioning, saving time and resources. Whether it's rugged landscapes, off-road locations, or remote oilfields, these rigs can efficiently reach the desired well site, reducing downtime and enhancing operational flexibility. Their self-propulsion feature ensures quick deployment and easy relocation, allowing oilfield operators to efficiently carry out workover activities across various wells in a timely manner.

Versatility and Adaptability

Heavy-duty self-propelled workover rigs are highly versatile, capable of performing a wide range of workover operations. These rigs are equipped with various integrated hydraulic systems, well servicing equipment, and lifting mechanisms, enabling them to handle different types of well intervention tasks. From routine maintenance, well cleanouts, and completions to more complex activities like sidetracking and re-entry operations, these rigs can adapt to the specific requirements of each workover operation. Their versatility allows oilfield operators to optimize well performance, minimize production downtime, and address well integrity challenges effectively.

Increased Efficiency and Cost Savings

Heavy-duty self-propelled workover rigs are known for their efficiency and cost-effectiveness. Their self-propulsion capability eliminates the need for additional equipment and transportation, reducing logistical complexities and associated costs. These rigs are designed for rapid rig-up and rig-down processes, minimizing downtime and increasing overall operational efficiency. The integrated hydraulic systems and well servicing equipment enable efficient execution of workover tasks, resulting in shorter well intervention durations. With faster turnaround times and optimized well performance, operators can maximize production levels and minimize revenue loss. The efficiency and cost savings offered by these rigs make them a valuable asset for oilfield operations.

Wide selection

workover rigs for service depths ranging from 1,600 m to 8,500 m (5,250 ft-27,900 ft), and workover depths from 2,000 m to 9,000 m (6,600 ft-30,000 ft) for 2 7/8″ DP.
