Literature Review of Water Alternation Gas Injection mohammed Alsharif Samba; Mahmoud Omran Elsharafi
Journal of Earth Energy Engineering Vol. 7 No. 2 (2018): OCTOBER
Publisher : Universitas Islam Riau (UIR) Press

The Water Alternating Gas (WAG) process is a cyclic method of injecting alternating cycles of gas followed by water and repeating this process over a number of cycles. WAG injection is to improve oil recovery, by both increasing the macroscopic and microscopic sweep efficiency and to help maintain the reservoir pressure. Also, WAG injection is to postpone the gas breakthrough. The WAG process provides mobility control in fast zones which extends gas project life and oil recovery. This paper provided a comprehensive literature study about WAG injection. This paper has collected most of the requirements of the petroleum engineers that has to know about the WAG injection started from basic concepts until the design parameter for WAG injection.

Oil recovery process is an essential element in the oil industry, in this study, a laboratory study to investigate the effect of temperature and aging time on oil recovery and understand some of the mechanisms of seawater in the injection process. In order to do that, the sandstone and carbonate cores were placed in the oven in brine to simulate realistic reservoir conditions. Then, they were aged in crude oil in the oven. After that, they were put in the seawater to recover, and this test is called a spontaneous imbibition test. The spontaneous imbibition test in this study was performed at room temperature to oven temperature 80 oC with different sandstone and carbonate rock with aging time of 1126 hours. The result shows that the impact of seawater on oil recovery in sandstone is higher than carbonate. At higher temperature, the oil recovery is more moderate than low temperature. Likewise, as the aging time increase for both sandstone and carbonate rocks the oil recovery increase.

In oil and gas drilling activities, drilling mud is one of the most important commodities. The main mineral used as a reactive solid that works to suck fresh water and form drilling mud is bentonite. Bentonite which is used as a drilling mud in the market is mostly imported from the United States. In Indonesia there are several areas that have enough potential for bentonite minerals, namely Java, Sumatra, parts of Kalimantan and Sulawesi with reserves estimated to be more than 380 million tons. This study uses bentonite in Kulim area, Tenayan Raya City, Pekanbaru, in hopes of providing useful information input, especially in the use of bentonite minerals in drilling mud. Using local bentonite the price is cheaper and more efficient. The object observed was the effect and number of bentonite mixed with fresh water so that the rheological properties of drilling mud such as viscosity, gel strength, mud cake and filtration loss were obtained and would be in accordance with API specification 13A standards. Whereas to find out the composition and structure of local mineral clay, SEM and EDX analyzes were performed to determine the characteristics and composition of these minerals. From these tests add additives NaCO3 and NaOH as ion exchangers and add the element Na to the sludge. From SEM and EDX analysis, two samples taken in central Sumatra Sumatra can be categorized as clay Illite fe-rich and Clay Illite Platty. Rheological testing of drilling mud and chemical composition analysis of clay Illite fe-rich minerals and Clay Illite Platty in Riau, Central Sumatra and with the addition of additives NaCO3 and NaOH to local Clay, Rheology in mud based on Clay Illite Platty is obtained with Bentonite. commonly used as a basic material for the manufacture of oil and gas drilling mud with API Spec13 A.

Spontaneous Imbibition Test of Low Salinity Injection at Low Saline Waxy Crude Carbonate Fiki Hidayat; Tomi Erfando; Borry Frima Maulana

Low salinity waterflooding (LSW) is categorized as one of emerging EOR technologies. It is done by injecting water with different salt composition and/or concentration. The research has been carried out for both sandstone and carbonate with the results looks promising. However, most of this research still concentrated in the north sea, middle east and North America region. This article discusses the applicability of low salinity waterflooding methodology in Indonesia. Spontaneous imbibition test is carried out to observe the recovery gain from a various combination of concentration and composition of the injected brine. The change of pH of the brine is also examined in order to confirm the pH effect mechanism. Three different concentration of brine (500 ppm, 5.000 ppm, and 10.000 ppm), three different brine composition (NaCl, CaCl2, and MgCl2) and high paraffinic crude oil are used as the fluid sample. It is found that the increased oil recovery is significant at a salinity of 10,000 ppm for MgCl2 and 5,000 ppm for NaCl ions. While the lowest recovery was shown by the test at a salinity of 500 ppm

The Critical Investigation on Essential Parameters to Optimize the Gas Lift Performance In “J” Field Using Prosper Modelling Fitrianti Fitrianti; Dike Fitriansyah Putra; Desma Cendra

The declining reservoir, oil production and pressure depletion with the well being produced, the results of the investment of the well will also decrease. For that there needs to be energy that can help to lift the fluid to the surface. One of the artificial lift methods that can be used is a gas lift. Gas lift is a method commonly used when there is a natural gas source as an injection gas supply. The selection of the artificial lift method is based on several considerations, namely the reservoir conditions, fluid conditions, well conditions, conditions on the surface, availability of electricity, availability of gas, and sand problem. The influential parameters in the selection of gas lifts include: Productivity Index (PI), Gas Liquid Ratio (GLR), depth of the well and driving mechanism from the reservoir. The Gas Lift that the production optimization wants to do is the injection system in a Continuous Gas Lift. Used in wells that have a high Productifity Index value. Where in the LB field to be analyzed, the Productifity Index value is 2.0 bpd/psi. This study intends to optimize a gaslift well performance as an effort to maximize the results of well production. Based on the research that has been done using Prosper Modeling on the “J” field, the following conclusions are obtained the effect of pressure and viscosity on the gas lift well flow rate in this condition can be said to be efficient, because the conditions / pressure given at temperatures below 300 F can reach the miscible condition and from the results of determining the optimal conditions to get the best well performance, obtain an optimal liquid rate of 1829.4 STB/D with an oil rate of 36.6 STB/D.
