Calfrac’s Smithfield, Pennsylvania operation performed above and beyond customer expectations on the first annular coiled tubing fracturing completion technique executed in the Pennsylvania Marcellus Basin. Using NCS Multistage casing sleeves, the treatment was performed with Calfrac’s CWS-600 Slickwater System.
Formations in the Western Canadian Sedimentary Basin are continuously being completed in the pursuit of optimizing sand placement during hydraulic fracturing operations. Typical fracturing techniques in the Montney and Cardium area have included placing proppant into clusters between zones, which does not homogeneously distribute stimulation fluid between the multiple perforation intervals.
Calfrac has specifically designed surface equipment and operating procedures to complete a +6,000m annular fracturing operation beyond the previously defined 10,000 psi pressure limitation.
Calfrac has done extensive research and incorporated theoretical and empirical results to extend pumping rates with annular fracturing to 7m3/min in 4.5” casing and to 10m3/min in 5.5” casing.
