Organic acids derived from petroleum fluids and dissolved in formation water might suffer decarboxylation upon postentrapment heating within the aqueous inclusion chamber, thereby generating excess CH4 in the inclusions. Fused silica capillary capsules (FSCCs), mimicking aqueous inclusions, were filled with acetic or formic acid solution and heated to 250°C in closed-system conditions. Thermal decarboxylation of acetic acid producing CH4 (and CO2) in the FSCC is observed, which confirms the possible enrichment in CH4 in aqueous inclusions after entrapment.
