Maintaining well integrity often feels like an uphill struggle. Collar and casing leaks are an ever-present menace, thief zones threaten oil recovery rates and the ingress of water, sand or gas can quickly bring production to a grinding halt.
With the advent of modern casing patches, isolating most of these problems has become much more straightforward. But isolating these problems without sacrificing the ID (internal diameter) of your well? That’s the real challenge.
Larger problem zones often span hundreds of feet and traditional big-bore straddles don’t stack neatly, which means that isolating several perforation intervals often limits the internal diameter of your well – Severely impacting your overall production rates.
Restricting the ID of your well also means that any future work on downhole intervals will be significantly more complicated, and it’s also important to note that most conventional straddles need to be deployed via a rig, which means bringing in expensive equipment and personnel for an extended period of remedial work.
That’s why we developed ReLine WL - a wide-bore casing patch that’s deployable via rig or wireline, capable of isolating multiple perforations in one trip and infinitely stackable – allowing you to tackle larger problem zones without decreasing the efficiency of your well.
