You’ve come to the right place if you are looking for more information about rigless well interventions. This article will go over the advantages and disadvantages of this type of intervention, the equipment used, and the costs. Whether you’re looking to replace a conventional well or install a rigless one, here are some facts about rigless intervention.


Advantages and Disadvantages of rigless well intervention

There are both advantages and disadvantages to rigless well intervention. While its cost advantage is clear, it has drawbacks. There are several ways to reduce risks, including the need to maintain a large rig. In addition, rigless well intervention may require significant manpower and equipment, which can be prohibitively expensive in the SSA region. However, its benefits outweigh the disadvantages. Read on to learn more. A rigless well intervention has several advantages over traditional rig-based methods. Firstly, rigless well intervention vessels can perform Phases 0 and 3 without a drilling rig. Another major benefit is that they are less costly than rig-based methods. Rigless rigs are particularly useful for performing pre-P&A operations on subsea wells, while a conventional rig is used for the remaining operations.


In the past, rigs were used in workover operations. A rigless well intervention, or RI, can involve coiled tubing, a slickline, or a wireline. Each of these methods can be used to solve specific well problems and improve the performance of a well. 

The apparatus used in rigless interventions is a substructure frame to perform the various well intervention and workover operations. These operations can include running completions, measuring cavern cavities, pulling damaged pipes, and testing inflatable plug systems. The rigless intervention apparatus includes a computer-monitoring system to ensure a successful rigless intervention. There are several advantages of using a rigless intervention apparatus. It is safe to operate, requires minimal equipment, and requires a minimum certification for operators.

The method uses a structure associated with the wellbore and has a maximum lifting capacity. It measures the weight of the component related to the well to determine whether the weight exceeds the lifting capacity of the structure. Lifting is stopped if the weight exceeds the capacity; otherwise, it is resumed. These methods are less complex than other well-completion and construction procedures. The rigless well intervention process is beneficial for oil and gas operations.

Equipment used

Rigless well interventions, also known as fracking, can be conducted without a rig at the site. Instead, they use coiled tubing, wireline, slickline, and other downhole tools. This course will provide you with a basic understanding of rigless well interventions, including their applications and operational contingencies. In addition to providing first-hand knowledge of what can be done without a rig, the course will also use real-world examples to demonstrate how rigless well intervention works.

The main benefit of a rigless well intervention is that it can be executed without a rig. It is also much faster to mobilize than a rig and offers more certainty of success. It can also be used in case of unexpected problems. However, the cost savings from a rigless well intervention can be significant. It is essential to find out more about the equipment used in rigless well interventions for such reasons.


The costs of rigless well intervention are typically higher than a rig-based insertion. Typically, a service like PRT Offshore deepwater well access interventions require a huge drilling rig, costing $100 million or more per well. However, in the future, engineers envision vessel-based interventions. They are also more flexible and can be dispatched quickly in unexpected difficulties. In addition, as oil prices rise, operators are looking for more and deeper oil resources, increasing the need for deepwater intervention services and rigless alternatives.

Light well intervention costs are lower than a rig-based intervention because a few personnel are required. Furthermore, light well interventions take less time to complete. Further, they can often be carried out by a single supplier, reducing the complexity and cost. It is one of the primary advantages of rigless well interventions. But, before investing in light well interventions, be sure to assess your options.
