/* Schlumberger */
-The technique involves drilling and fracturing a first lateral wellbore; plugging the first lateral wellbore; and then drilling and fracturing a second lateral wellbore, plugs or other suitable isolation devices to isolate lateral wellbores and to enable the fracturing of specific lateral wellbores.
Method enables the continuous pumping of fracturing fluid during fracturing of multiple lateral wellbores due to a single rig mobilization....[Contd]
 ===Information from the Articles=== 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]
