Science of SIP
The closure of the SIP control valve backs up gas and pushes down the liquid column of oil and water in the well. This increases the bottom flow pressure and holds back the gas that is mixed in with the crude from being released. The oil is less viscous and more mobile than before as it is pulled towards the pump.
The mobility of the water, however, stays the same. The pressure slows down the water flow in both the well and the reservoir, while more oil than before moves up.
The pressure also breaks up large gas bubbles in the liquid, making the liquid’s texture more consistent and allowing the pump to operate more steadily and efficiently. Added crude is pushed to the surface.
The technology is especially effective for secondary and tertiary production in established reservoirs, invaded by ever more water.
Heavy oils disproportionately benefit compared to light ones.
THE SCIENCE VISUALIZED
Gas column is compressed when annular pressure is increased by the effect of the equipment pressurization, increasing multiphase fluid density (fluid volume), resulting in pumping and production efficiency.
