Abstract
A system includes rotational ball seat (RBS), remote operated, and electrical/hydraulic sections. The RBS section includes a spring, a first internal sleeve, and an upper RBS. The remote operated section includes a lower rotational ball valve (RBV) disposed between second and third internal sleeves, and a setting sleeve operatively connected to the lower RBV. During miming-in-hole, the upper RBS is in a restricted position, and the lower RBV is in an open position. The spring compresses the internal sleeves, which sandwich the upper RBS and the lower RBV, until a shear event occurs. An inner diameter of the system closes to facilitate setting of hydraulic equipment. Thereafter, the shear event releases the spring, thereby pushing the internal sleeves, the upper RBS, and the lower RBV downhole, which rotates the upper RBS and the lower RBV into open positions, thereby opening the inner diameter of the system.
