Manifold implemented in multi-channel system for controlling flow of fluids in oil well

Abstract

Disclosed is a manifold implemented in multi-channel system deployed in an oil well for controlling flow of fluids. The multi-channel system includes plurality of passageways to transport one or more fluids from the oil well. The manifold includes body having plurality of inlet ports and plurality of outlet ports, and a flow control arrangement provided in the body. The flow control arrangement including a channel formed between each one of the inlet ports and one of the outlet ports, and a check valve arranged in the channel at each one of the inlet ports of the body. The channel is adapted to receive fluids through the inlet port of the body creating a differential pressure between the inlet ports and the outlet ports. The check valve is configured to regulate flow of fluids into the channel based on the created differential pressure.
