ABSTRACT

Cementing is the most important part of well construction and requires effective compatibility with nitrogen (N2) additives. Some of the challenges associated with this process are high temperatures, brine corrosion, and CO2 gas. The cementing process in geothermal wells is similar to oil and gas with high displacement efficiency to ensure adequate processing during low velocity. This study, therefore, aims to determine the function of foam cement using nitrogen to improve zonal isolation. The low use of variable density and relatively high strength of the foamed cement help operators to achieve long-term hydraulic bonds and zonal isolation by preventing hydrostatic pressure damage. In Indonesia, geothermal wells are developed with the fracture and low temperature gradients using lightweight foamed cement. This ensures job success, proper engineering, and control.. The results foam cementing are to establish good bonds and zonal isolation, the engineering process allows operators to adjust slurry density during cementing as needed. It is first mixed then pumped into a hole, and stabilized to create foam. This study concludes foam pumping has the ability to improve zonal isolation in oil and gas drilling wells.
