Abstract

This study evaluates the suitability of silica sand from Rupat Island, Indonesia, as a natural proppant candidate for hydraulic fracturing applications, based on API RP19C specifications. The investigation involved three samples: unmodified silica sand, 5 % resin-coated sand, and 10 % resin-coated sand. Key properties assessed include roundness and sphericity, bulk density, turbidity, acid solubility, and crush resistance. The results show a significant improvement in roundness and sphericity with resin coating, with the 10 % coated sample reaching a value of 0.7—meeting the API minimum requirement of >0.6. All samples exhibited bulk density values exceeding the API minimum of 1.5 g/cc, specifically 1.53 g/cc, 1.58 g/cc, and 1.60 g/cc, respectively. Turbidity values were also low, ranging from 20 to 38 NTU, well below the API limit of 250 NTU. Acid solubility decreased with increasing resin fraction, from 2.8 % (uncoated) to 2 % and 1.2 %, all within the acceptable API limit of <3 %. In the crush resistance test using 40/70 mesh, all samples demonstrated acceptable levels of particle degradation: 6.7% at 2000 psi for uncoated sand, and 9 % and 8 % at 6000 psi for resin-coated samples—each remaining below the API maximum of 10 %. These findings suggest that Rupat Island silica sand, when modified with resin coating, holds strong potential as an alternative proppant for hydraulic fracturing operations.

Abstract

The reduction in oil production rates due to the formation of calcium carbonate (CaCO₃) scale deposits on production pipes is a common problem in upstream oil and gas operations. This study aims to evaluate the effectiveness of acetic acid produced from pineapple peel fermentation, alone and in combination with hydrochloric acid (HCl), as an organic-based scale-removal agent, with EDTA-2Na used as a comparison via chelation. The research methods included acetic acid extraction via two-stage fermentation, characterization of functional groups by infrared spectroscopy (FTIR), and analysis of mineral scale composition by X-ray fluorescence (XRF). Scale testing was carried out using the weight-loss method with immersion times of 30, 60, and 90 minutes. FTIR results showed the presence of characteristic organic acid functional groups, while XRF results confirmed that the scale was dominated by calcium as the main component of CaCO₃. The test results showed that the mixture of acetic acid and HCl provided the highest effectiveness with a mass loss of 0.43 grams at 90 minutes, followed by pure acetic acid at 0.36 grams, while EDTA-2Na produced a reduction of 0.08 grams. These results indicate that biomass-based acetic acid has the potential to be a more environmentally friendly alternative for scale removal in oil and gas production piping systems.
