The Effect of 4% NaCl Concentrations Addition on the Properties of High Performance Water-Based Mud Polyamine on Laboratory Scale

Abstract

Drilling mud is used as a fluid that plays a role in achieving the success of a drilling program. Failure to control the physical properties of the drilling mud will result in its failure. High Performance Water Based Mud (HPWBM) mud systems different with water base mud (WBM) conventional Which where is HPWBM can act like oil base mud (OBM) in matter lubrication and resistance to solid contamination. NaCl contamination causes stability drilling mud decreased so that the mud's ability drilling. This research aims to determine the effect of NaCl addition on the properties of High Performance Water Base Mud (HPWBM) Polyamine on a laboratory scale. This research was conducted at the BPPMGB Lemigas Laboratory, an institution that plays an important role in the development of oil and gas technology. This research evaluated the effect of 3%, 4%, and 5% NaCl contamination on the properties of Polyamine HPWBM mud. The results showed that the addition of NaCl changed the physical and rheological properties of the mud. Under BHR conditions, 3% NaCl gave the results closest to specifications, while under AHR conditions, 4% NaCl showed the best performance. Increasing the NaCl concentration increased the viscosity and stability against swelling clay, but also increased the potential for corrosion due to changes in the chemical properties of the drilling fluid.
