Saldungary et. al., 2008 of '''Schlumberger''', studied on Efficient Multifractured Horizontal Completion change the economic equation in Latin America; they have discussed the effect of '''Effective Multistage Fracturing System (EMFS). '''The system consists of mechanical open hole packers, are capable of withstanding high differential pressures at high operating temperatures, with specially designed fracturing ports (FracPorts), are located between the packers. It shows completion of horizontal wells in a time efficient manner (Time savings of 10 days were observed while increasing the number of frac stages from 3 to 5), and reduction in completion cost can be done easily, maximized reservoir contact and productivity in treated wells. MEFS had increased the gas production rate to 543000m<sup>3</sup>/day per well....[Contd]
===Summary of Multi Stage Fracturing===
From the patents, it's observed that Schlumberger employs a continuous multistage fracturing of lateral wells and focused fracturing placement....[Contd]
From the articles, it can be concluded Schlumberger, is focused on effective multistage fracturing system (EMFS)....[Contd]
