In oil and gas operations, wellhead equipment is the component that connects the casing and tubing to a gas or oil pipeline. As worldwide demand for oil and gas continues to increase, the industry is consistently working to maximize their output by using safe and reliable processes. And that extends to wellhead monitoring equipment.
Since oil and gas worksites are often in remote and rugged locations such as sub-sea locations, onshore, or offshore platforms, many of them are designed to run unattended for prolonged periods.
Typically, wellheads are fixed in one spot. However, with exploration wells, wellhead equipment is subsequently reused.
Wellheads are designed to provide support, particularly to the tubing and casing strings. Wellhead equipment seals the different tubing and casing strings. It also permits operators to access the space between the strings.
The main parts of wellhead equipment are the casing head, casing hangers, casing spools, isolation seals, pack-offs, test plugs, bowl protectors, tubing heads, tubing head adapters, tubing hangers, and mud-line suspension systems.
Downtime is equivalent to lost revenue. Thus, oil and gas companies make it their priority to have top-of-the-line wellhead monitoring equipment.
Choosing a Wellhead Equipment
When selecting suitable wellhead equipment for your oil and gas operations, consider the following factors:
Operators tend to go with shorter polished rods. If you have a problematic well, shorter polished rods may cause an issue when operators drop it at the bottom of the well. When you have an adequately sized polished rod, it can entirely drop the stuffing box during each stroke.
The upper part of the polished rod must cover the bridle carrier bar while giving it enough space to attach a clamp. It must also have additional space for the string to descend to the bottom.
Polished Rod Clamp
Polished rod clamps are used in transportation. These clamps strengthen the rod string, whereas the bridle and carrier bar hold the additional weight. Polished rod clamps are also heavily used to prevent different types of spills. Thus, when choosing a wellhead equipment, pay particular attention to polished rod clamps.
Polished Rod Liner
A polished rod liner protects the polished rod from deterioration. The liner is placed on top of the polished rod. To make sure that you’re getting a good-quality polished rod liner, add an extra two feet to the stroke length.
If the polished rod liner is not the correct length, it tends to click to the obstructions in the wellhead during operations. Worse, it can create issues when trying to reach the bottom of the well.
Are Wellhead Monitoring Equipment Important?
The short answer is yes. Until recently, wellheads were built with pressure sensor alarms. These alarms get activated when monitoring the outflow pressure and if it drops below a specified level.
Nowadays, wellhead monitoring equipment are built with more sophisticated features.
Acquiring real-time data is critical – so much so that it has become the main driving force of the oil and gas industry to ensure success in their operations.
Oil and gas companies have learned that as they acquire better and more reliable data and information, the more they can come up with better business decisions – which ultimately leads to success and growth.
Digital Innovations in the Oilfield Maximizes Productivity
The concept of a digital oilfield is now a reality for oil and gas companies. Wellhead monitoring equipment can be connected through secure satellite networks nationwide or worldwide to function as centralized control and monitoring unit. This is especially beneficial for oil and gas companies with national or global offices.
Digital innovations, when applied in oil and gas operations, maximize productivity, reduce downtime, and help diminish operational costs.
Wellhead monitoring equipment typically uses cellular connection and service.
However, when the operations extend past national borders, that may become an issue. Secure satellite networks can create a seamless wellhead monitoring equipment function.
Wellhead Monitoring Equipment Maintenance
Regular maintenance mainly increases the wellhead monitoring equipment’s lifespan. It also ensures that operators can proactively deal with any impending issues on the wellhead monitoring equipment.
However, because of the remoteness and ruggedness of the worksites, as well as extended exposure to the elements, wellhead monitoring equipment may have problems – even with scheduled maintenance and upkeep.
