Reliable Testing Made Easy.  

When we mention subsea trees to someone outside of the petroleum industry, we are likely to be greeted by stumped gazes and general confusion. This can just go to show just how complicated the realm of drilling for petroleum can be. Drilling for petroleum requires not only the highest safety standards, but also requires an immense amount of vigilance and needs those on the project to constantly be on the lookout for any irregularities or problems. One small mistake can lead to the whole project failing in the best case scenario, and in the worst case scenario it can cause immense destruction as leaks of natural gas or petroleum by-products can end up polluting our environment. Therefore, a large amount of equipment is used to monitor the wells and the underwater drilling equipment at all times. Alongside using deep sea pressure monitors, subsea trees are also part of the equipment that closely monitors the flow and controls production from a subsea well. With catastrophes such as the Deepwater Horizon incident still on our heels, and the environmental damage being set to last for ages to come, ensuring safety should be the utmost priority of anyone attempting to get oil from underwater reserves.  

Subsea trees are well known in the petroleum industry to be used whenever we need to drill underwater for oil or natural gas reserves. Designed somewhere around the 1950’s, subsea trees are used to cover underwater well heads to monitor and control flow. Of course, these trees aren’t actually trees, but rather a connected system of valves, spools and other fittings that form a large web system. These trees can be either horizontal or vertical, depending on the need and also the location of the deep sea wells. Then from here, the trees can further come in a number of different specifications. Nevertheless, no matter what the specification, the subsea trees are used mainly to monitor production and flow through the pipes. 

However, while the subsea tree manufacturers monitors flow of oil or natural gas, the subsea tree itself needs to be monitored as well. This can be an exceptionally difficult task as the subsea tree is underwater, and can require diver intervention to ensure that all systems are working well. The lifespan of these underwater trees can be super hard to monitor should we not have the right equipment, as even if we do manage to arrange for diver intervention, human checks cannot be relied upon. Here is where pressure testing equipment can enter and help. A simple plug in to your ROV or subsea tree can help you monitor the pressures and temperatures on the go. These testers can withstand depths of up to 4000 meters and provide to you objective and reliable data from which you can easily judge the safety of operations. 

Whereas the technology in use earlier had remained largely not updated ever since the 1800’s, this subsea tree testing can be the safe and modern way of staying in check with safety regulations. Furthermore, this new technology gets rid of all the subjectivity of the past, where it was up to the regulator to decide whether or not the test was passed or not. This testing equipment can provide solid statistics rather than vague statements and can tell you in a few moments whether the oil rig is safe or not. This can be a relief for everyone involved – all the stakeholders can have the information delivered to them by email so that anyone involved can know just how safe and smooth the project is running, and just what they can expect to come from it.  

Drilling for oil can be a complicated and unsure process even for those who have been in the industry and are well-versed. Recorders from DARTT can help take some of the confusion away and can help you monitor the safety and the efficiency of the subsea trees accurately. A simple plug and play system can give unparalleled objectivity and efficiency to make sure that your systems are safe and secure not just for the personnel but also the environment. No matter what kind of subsea system you have, these pressure recorders can be very helpful.
