Abstract
As time goes by, there will be a decline in formation productivity, as reflected in the decline in the rate of oil production from production wells. The decline in the rate of production was caused by many things such as a decrease in reservoir pressure, also formation damage. Where damage to the formation will result in a decrease in rock permeability. The decrease in rock permeability is caused by the blockage of rock pores due to the invasion of solids and drill mud filtrate, cementing, fluid fluids or previous stimulation. Besides the small rate of oil production can also be caused by the low natural permeability of rocks. With the decreasing productivity of the formation, it is necessary to make efforts to increase the productivity of the formation again, where one of them is by the method of hydraulic fracture stimulation. In this analysis, we will discuss the difference between conventional stimulation methods and flow channel fracturing. Flow channel fracturing is a fracturing process by making a network around proppant granules to form proppant pillar, so that a path is formed for the fluid to flow more easily. What distinguishes between conventional hydraulic fracturing with flow channel fracturing is the resulting fracture form, fracturing fluid injection pattern, and the amount of proppant used.
Highlights
Stimulation is the process of stimulating wells to increase the flow of fluid in the reservoir layer that is experiencing formation damage
Hydraulic fracturing operation can be done in two ways namely the conventional method and the flow channel fracturing method
Flow channel fracturing operations have various names according to the company that applies the method, such as EC Prime on Baker Hughes and HiWay Fracturing at Schlumberger, the fracturing fluid injection pattern and the number of proppants used will vary according to the provisions of each company
Summary
Stimulation is the process of stimulating wells (to repair) to increase the flow of fluid in the reservoir layer that is experiencing formation damage. The stimulation process has been used to increase oil and gas production from underground reservoirs for more than forty years. The stimulation method most often used to increase the productivity of wells that have experienced formation damage is acidification, or hydraulic fracturing. Hydraulic fracturing operation can be done in two ways namely the conventional method and the flow channel fracturing method. The purpose of this study is to analyze the differences from conventional fracturing with fracturing flow channels
