Definitions
- the present invention relates to the injection of fluids into oil reservoirs for pressure maintenance. More particularly, the present invention relates to simultaneously and alternately injecting water and gas into subsea wells for increased production and the oil recovery factor.
- the WAG method may have better oil recovery rates when compared to the water-only injection method.
- the WAG method including the simultaneous injection of gas and water in one well.
- Another problem of using a line to flow either gas either water, if gas contains a percentage of C0 2 above 1% is the need for special metallurgy and fluid switching operational procedures by displacement with an inert fluid beds, avoiding that CO 2 reacts with water to form carbonic acid, a substance which has a high corrosivity.
- multifunctional submarine systems that is, that combine injection to increase the factor of recovery of reservoir with a greater robustness of hydration mitigation, and also with the possibility of injecting water captured directly from the seabed, may become attractive.
- the present invention is intended to solve the above-described problems of the prior art in a practical and efficient manner.
- the present invention aims to provide an integrated gas and water injection recovery system which avoids the need for an underwater manifold,
- the present invention further aims to provide an integrated gas and water injection recovery system having a higher hydrate robustness.
