• Despite advances in horizontal completion methods over the past 10 years, multistage fracturing did not gain significant traction as a viable completion method in the eastern hemisphere until recently. Hampered by limited technical development and a shortage of both necessary equipment and experienced personnel, risk-averse operators couldn’t take a chance on large-scale application of the technology.

    National Oilwell Varco (NOV) decided to change this by introducing its Burst Port System (BPS™) and cup-to-cup tools, from the Completion Tools business unit, to address the unique needs of an operator in Eurasia. The operator needed to improve the initial production of wells in a challenging oilfield where reservoir rock was largely sandstone with low-permeability shale and hydrocarbons were trapped in anticline structural traps. 

    Implementation of the systems in a pilot test validated their performance, and actual field results saw two sets of wells achieving higher production than expected, with cumulative production almost doubling versus that of conventionally completed wells. The project validated not only that substantial production increases were possible using multistage fracturing in the region but that production increases correlated with increasing the number of stimulation zones. Furthermore, the operator determined that reducing the distance between zones didn’t negatively impact fracturing success.
