Abstract
In this thesis, we are going to present a new technique to analyze the skin and permeability of the gas condensate reservoirs using flowing production data, which are the rate and pressure. We performed this technique in four steps to reach our conclusion of the study. The first step is determining the permeability and skin of the reservoir using pressure transient analysis “PTA”. The second step is determining the permeability and skin of the reservoir using rate transient analysis “RTA”. The third step is comparing the data obtained from the PTA and RTA to assess the quality of RTA in gas condensate reservoirs. The last step is using the data obtained from the rate transient analysis to take quick decisions about well intervention. RTA is now a proven method to estimate the reservoir parameters of skin, permeability, and the gas or oil in place. The main benefit of RTA is that it uses the production data, which are already available, as a good practice of production for most of the companies. Therefore, we can constantly update our status of the reservoir parameters to facilitate our decisions concerning our reservoirs. PTA is a proven method to characterize the reservoir, so we are not trying to replace the PTA with RTA; we just want to use each one of the two methods in their perfect position. PTA requires shutting the well and stopping production in addition to the cost of service itself. Finally, this study provides a new technique to analyze the gas condensate reservoir using RTA to dynamically update the reservoir and help in facilitating the decision-making process even in the well that has not been subjected to PTA. The study uses the daily production data in RTA to analyze only the transient period to extract the skin and permeability in the gas condensate reservoir.
