Polymer injection is one of the EOR methods using chemical which is injected into the reservoir to increase oil recovery. The polymer functions to maintain the flow of fluids, especially water, so that it does not boil ahead of oil towards production wells. This is due to the ability of the polymer to increase the viscosity of the fluid in the rese...

To determine the performance of terrafloc polymer, we must first know the characteristics of the polymer because all of these will affect the increase in oil recovery. Many factors affect the performance of the polymer. Here, using a micromodel to see the movement of oil in 2D, the sweep efficiency of the polymer injection can be seen clearly. The...

Given the current public need for oil and gas as a primary energy, all oil and gas companies need to increase production to meet this demand. One of the things companies usually do to achieve this is to evaluate and analyze the productivity of each well. Of course, production decreases from time to time, so the company must try to increase its prod...

The Enhanced Oil Recovery method is a method that can be attempted to increase the recovery of petroleum. One of the materials that can be used is Methyl Ester Sulfonate surfactant from palm oil, as a vegetable surfactant whose raw materials are widely available in Indonesia. In this study, the compatibility test of Methyl Ester Sulfonate surfactan...

One of the efforts that can be done to evaluate the performance of water injection in a field is by monitoring the injector wells. Observations can be made by looking at the flow rate and injection pressure at each injector well. The response given by each injection well will be able to represent the injection performance on a field scale. The EX s...

In the petroleum industry, Enhanced Oil Recovery (EOR) technology has been developed to obtain increased oil recovery from reservoirs. One of the EOR methods is chemical EOR using a surfactant known as the surfactant flooding method. Surfactants have the ability to reduce the interfacial tension between oil and water in the rock matrix so that resi...
