Ceramic screens control proppant flowback in fracture-stimulated offshore wells

Maersk Oil operates a large portion of Danish oil and gas fields, producing some 300,000 boepd. The reservoirs are mainly tight Cretaceous carbonates with low permeability, which means many wells must be stimulated with propped hydraulic fracture treatments to produce economically. To address wells that required additional stimulation, the operator implemented controlled acid jetting liner and perforate-stimulate-isolate (PSI) completions. The latter completion method is generally used along with frac treatment, and benefits reservoirs with permeabilities ranging 0.5–2.5 mD.
