From gas work to oil rigs, there is a lot of different work that occurs offshore today. If your business is involved in this sector, one area you may have to deal with regularly is well intervention. Or, perhaps you want to know more about this because it is something you could be coming into contact with for the first time? Project managers and those venturing into other career paths can often experience this. Either way, below you will find out more about these projects to help you get a better understanding.

Well intervention projects are varied and regularly carried out. This relates to any type of operation that is carried out on gas or oil wells, either at the end of its productive life or during. These operations can take place in order to enhance production management, to retrieve well diagnostics, to alter well geometry, or to alter the state of the well itself.

Consequently, well work makes up an imperative part of offshore asset management for businesses, as there are many approaches to well intervention and lots of different costs involved. With that being said, let’s take a look at some of the different types of well work below.

1. Subsea Well Intervention

Let’s begin with one of the most complex forms of well work. Subsea well intervention is something that demands a lot of advance planning, as it poses many challenges. This type of intervention is expensive and they tend to be executed using mobile offshore drilling units (MODU) or light/medium intervention vessels.

2. Snubbing

Snubbing involves performing the required well work by forcing a string of pipe into the well against wellbore pressure. It is also commonly referred to as hydraulic workover.

3. Coiled Tubing

Coiled tubing is used in various tasks. It can be used in instances where the well deviation is severe to the point whereby a wireline tractor cannot be used. It is also ideal when you need to pump chemicals directly into the bottom of the well, for example, during a chemical wash or circulating operation.

4. Maintenance On The Wellhead

Annual maintenance can involve testing valve pressure and greasing the hardware. Pressure testing can often occur on the downhole safety valve too. This all depends on the condition of the wellheads.

5. Pumping

Let’s end with the simplest form of well intervention – pumping. This approach does not involve any hardware being put into the well itself, and it is often used to pump chemicals into the well and lifting and rigging up to kill wing value on the oil well.

As you can see, there are many different types of well intervention projects that can be carried out. Hopefully, you now feel like you have a better understanding regarding this work and what it means for offshore businesses, whether you work for one or you are looking to find a company to provide such services for you.
