Activation of a dead well by injection of hot steam

In the context of oil and gas extraction, a dead well refers to a well that has ceased to produce hydrocarbons.This can occur because the reservoir has been depleted, the pressure has dropped too low to allow for extraction, or there are technical issues such as blockages or equipment failure.The main purpose of this paper is to activate the death well called K22 (for confidential reasons) by injecting hot steam into the reservoir to reduce the viscosity of oil and increase the production rate.PVT, reservoir, well, completion and injection data are entered via prosper and Reveal software's in order to analyze the performance of the initial well, to implement the hot steam injection method and to analyze the performance of the well K22 after the injection of hot steam using the nodal analysis method.The results initially obtained show that well K22 does not produce.To solve this problem, the injection of hot steam method provides from the nodal analysis for a liquid production rate of 2200 STB/day and a critical pressure of 2337.78 psi where the production rate of oil is 2187.8STB/day, the water production rate is 21.1 STB/day and the gas production rate is 0.10894 STB/day for water cut of 0.92 %.The hot steam injection method is appropriate to put in production in well K22 because it reduces the density of the oil which facilitates its flow towards the production well, even though it does not completely solve the problem of water.Therefore, it maximizes the oil production and it allows a profitability of $ 3158366.721with a return on investment after 3 months and 3 days for 4 years of production.This means that it is possible to recover all the initial cost of exploitation by steam injection within 3 months and 3 days with the production still profitable for up to 4 years.
