Wellcem Applications

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 ...

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.

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.

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.

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.

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.
