Abstract

Hydraulic fracturing is commonly practiced worldwide in the oil and gas industry to enhance production, particularly in wells with low permeability or formation damage around the wellbore. The design of fracturing fluids used in hydraulic fracturing primarily consists of water. However, using water as the main component presents challenges, especially in remote locations with limited access to clean water, and when clean water is available, it can be expensive. Therefore, research has been developed to create fracturing fluids using formation water obtained from the field, supplemented with synthetic brines.
The research methodology involved creating fracturing fluids with various compositions: distilled water (aquadest), aquadest with 200 ppm barium ion content, aquadest with 300 ppm barium ion content, and formation water from the RTP field. The viscosity of the fracturing fluid samples was measured, heated until breakdown, and the amount of residue was quantified.
The analysis revealed that fracturing fluid samples with higher barium ion content had lower viscosity and higher residue. Additionally, samples with higher barium ion content exhibited lower proppant transportability under high temperature and pressure compared to those with lower barium ion content.
