Background: Several challenges exist in obtaining an optimal biopolymer material that is cost-effective, resilient under harsh conditions, and environmentally friendly. Currently, only xanthan and Schizophyllan biomaterials have been applied at a field scale. This study introduces a novel Samba biopolymer material for Enhanced Oil Recovery (EOR), which is economically viable, readily available, and stable.
Methods: Experimental tests were conducted to evaluate the Samba biopolymer. Infrared (IR), X-ray diffraction (XRD), and X-ray fluorescence (XRF) analyses were performed on the seeds before extracting the biopolymer solution. Subsequently, rheology, compatibility, membrane tests, particle size distribution, and filtration tests were conducted. A core flooding test was also carried out to measure the biopolymer's oil displacement efficacy; however, this test was performed for only one concentration scenario to serve as a preliminary evaluation of the polymer's performance under reservoir-like conditions.
Significant Findings: The extraction of the biopolymer solution from organic seeds was successful, with thermal extraction being sensitive to heating time and temperature. The Samba biopolymer enhanced water viscosity, recommended for reservoir conditions. Different concentrations revealed variations in rheological and filtration properties due to distinct morphology and surface functionality. Under optimal conditions, a remarkable 74% maximum oil recovery was achieved, demonstrating the biopolymer's potential as a promising EOR agent.
