Abstract

The current Plug and Perf (PNP) method used for multi-stage hydraulic fracking in horizontal wells (for shale gas and unconventional reservoirs) relies on a geometrical approach to determine the zones to be perforated, where shots (zones to be fracked) are evenly distributed along the horizontal section at a consistent spacing, with the intent of covering as many of the viable zones across that section as possible. Although this way of designing the perforating plan has been satisfactory to some extent, it does not guarantee that all the producing zones are hit and fractured. It also implies that zones of lower hydrocarbon content or less prone to fracking are being shot and tentatively fractured, using unnecessary Frac crew time and horsepower. Shooting in the plane of minimum principal stress also makes the fracking process more time and energy consuming. The intent of this invention is to come up with a perforating platform that will allow positioning the perforating guns at the best spots and in the right direction before they are fired to ensure an efficient and optimum fracking operation.

Detailed Description:  The platform will allow perforating systems to correlate to mineralogy and geology data acquired by previous services ran in the well, such as imagingand production logs will determine the In Zone/Out of Zone positioning in the well (IZ/OZ), the Total Organic Carbon Index (TOC...
