Whether looking for a new job or interested in the field, you should know five things about rigless suitable intervention needs. These things include the cost of rigless good intervention, the current applicability of semi-submersible rigs, riserless healthy intervention vessels (RLWI), and light construction vessels (LCV) for different phases of subsea P&A operations, and the use of robotized machines in crewless operations.
Mechanical Conditions
Some mechanical conditions, like offshore well intervention, need to be considered during the excellent intervention process. These conditions include the ability of the rig to lift and carry the equipment. Also, the rig floor activities require autonomous control.
To determine the lifting capacity of the rig, it is essential to decide on the weight of the component associated with the well. The element’s weight is then compared to the maximum lifting capacity of the structure. If the weight exceeds the structure’s degree, the lifting component associated with the well is terminated. However, the lifting member is resumed if the weight is within the structure’s power.
Typical wireline operations involve perforating, cleaning wells, logging, dumping cement, and running tools into the well. Wireline operations can also be conducted on the wellbore under pressure.
Energy Conditions
Typically suitable interventions, such as rigless intervention systems, include remedial cementing, selective stimulation, and reservoir management. These are typically performed to remedy production problems and increase production. However, performing well interventions to access additional hydrocarbon pay zones is common. The decision to perform such an intervention depends on the reservoir, infrastructure, and economics.
The most common reason for good intervention is remedial cementing. This involves injecting cement slurry into the main reservoir. The slurry is then tested for strength, and a cement plug is inserted. Cementing operations are typically performed on the wellbore, although some operators use wireline techniques.
Another common well intervention is reservoir abandonment. This is part of the excellent barrier envelope and isolates the reservoir from the wellbore. To isolate the pool, a wellhead system and wellbore system are required.
Current Applicability
During a recent seminar held at the Petroleum Institute of Norway, researchers from Norway, the USA, Canada, and Singapore presented an overview of the current applicability of semi-submersible rig (SSRI), riserless healthy intervention vessel (RLWI) and light construction vessel (LCV) for different phases of subsea P&A operations. In addition, the research team introduced and illustrated the key features of these types of containers.
The RLWI vessel uses a riserless system that allows entire P&A operations to be carried out on subsea wells. The ship is held in position by a dynamic positioning (DP) system. It also includes a turret mooring system, which allows the vessel to rotate.
The riserless system allows the vessel to be dynamically positioned over the well when underbalanced drilling. RLWI vessels can also be used for multi-well P&A operations. The RLWI vessel uses an optimization approach to plan the multi-well P&A operation. The system allows planners to evaluate the impact of different strategies. It also allows the planners to assess the impact of a changing rental rate.
Robotized Machines
Whether in a factory, on an oil and gas well, or in the field, robotic technologies are advancing to improve operations and reduce costs. Increasingly, they are also becoming more innovative and versatile. With these technologies, real-time data-driven decision-making and inspection capabilities are integral to oil and gas operations.
A new generation of ground robots is being developed to support crewless field operations. These robots are highly maneuverable and able to support surveillance and inspection. They are also designed to integrate top-mounted robotic arms, enabling local panel control.
Robots can inspect shorelines and land mines on the battlefield or perform rescue missions. They are also being used in financial services and agriculture.
Oil and gas companies are using robots to enhance operations, reduce costs, and ensure the safety of employees. They are also being used to help streamline surgical procedures, deliver food packets during emergencies, and prep IVs.
Cost of Rigless Suitable Intervention Needs
Performing well intervention and remedial operations are increasingly important for oil and gas companies. With the increase in energy demand and deep water activities, the rigless intervention services market is expected to grow at a CAGR of 10 percent during the forecast period.
Well, intervention is typically performed to increase production, remedial cementing, or access additional hydrocarbon pay zones. However, these operations can be costly. To decrease costs, operators can implement rigless healthy intervention techniques. In addition to eliminating the need for a conventional workover rig, rigless techniques also reduce downtime, transportation costs, and crew movement.
A rigless healthy intervention method allows the operator to perform downhole applications in live wells. This approach can improve scheduling flexibility and increase oil recovery rates.
