Application

Plug & Abandonment

The primary objective is to ensure that no leaks to surface exist and that no formation fluid migration occurs even many years after the well has been abandoned.

Application

Zonal Isolation

Most oil and gas wells have different zones. Zonal isolation seeks to segregate undesirable intervals from production.

Application

Sustained Casing Pressure

Regardless of definition, either SCP, SAP or CCA, it is a well integrity issue with a failed barrier. It requires management or workover.

Application

Casing Leak

Casing leaks are often a result of leaking casing threads, burst casing from pressure, corrosion or from casing wear due to extended periods of drilling operations.

Application

Lost Circulation

Lost Circulation means you are losing your circulation of fluids off to a low-pressure and permeable formation somewhere in the well.

Application

Control Line

Many wells have a hydraulic control line running down along the casing or tubing. Control lines can develop an undesired leak.

Wellcem solves your land-based and offshore well challenges

How we work

This process start when we have an identified well candidate.

Our Project Engineer will follow the project from start till finished.

Collect relevant data

Collect relevant data

The project engineer will communicate with the relevant engineer in the client team, collect all necessary information and work out and agree on a detailed technical plan

Design

Design

Do tentative lab tests. Work out technical solution. Upon agreement of the work (PO), the project engineer will ensure our lab designs a recipe that meets the agreed properties

Prejob

Prejob

Perform final lab tests. When timing of the job is established, the project engineer will arrange for all logistics and also coordinate as needed with other service providers

Execute

Execute

The project engineer will be on the rig ensuring the job is executed as planned

Post job

Post job

The project engineer will make an “End of Job” report to summarize up the result, lessons learned and recommendation for future work

Sustained casing pressure problem

Case Study

In order the fix the problem: A chemical would have to be gravity fed into the annulus and allowed to fall on to the top of cement. This will be followed up with a squeeze, in order to squeeze the chemicial into the micro annuli.  The fluid in the annulus was waterbased, which eliminated cement as an option. Wellcem resin system was ...

Plug & Abandonment through A-Annulus

Case Study

An Operator in the Norwegian sector had a well which was a candidate for first phase P&A. The well had low reservoir pressure, i.e. well on vacuum. Among other options, the customer considered and selected ThermaSet to solve their challenge.

Plug & Abandonment through tubing

Case Study:

Due to a collasped tubular using cement to isolate this well was not a good option. Using cement would run the risk of bridging off and not being to pump the desired volume below the collasped area. Wellcem Resin System gave the ability to pump below the collasped area, setting a plug to fully isolate the in the well.

Gas Channeling in Cement behind Casing

Case Study

After several attempts to solve the problems with cement and being on location much longer than planned. It was decided to use a Wellcem Resin System to squeeze and isolate the gas channels. The low visicosity of the resin allowed in to get into the micro channels and seal of the movement of gas to the surface.

Casing leak – Fairview Field, Queensland

Case Study

The Operator on the Fairview Field in Queensland, Australia had a challenge with casing leak. A cement plug would fail to plug this well, because the formation pressure cannot withstand the weight of cement.

Placement of reservoir plug in well - UK.

Case Study

The Operator on the UK Sector of the North Sea had a challenge with low reservoir pressure and tubing integrity. The customer needed something that could be pumped passed the damage area in the tubing without the risk of bridging or blockage.
