The investigation of elemental sulfur solubility plays critical roles on sour gas reservoir development. In this paper, the solubility of elemental sulfur was directly measured by static method with gas samples from well M1 of a sour gas reservoir in Sichuan Basin. The results show that the solubility of elemental sulfur ranges from 0.001 g/cm3 to 0.968 g/cm3 at 40–98.9 MPa and 15–49.8 MPa. The elemental sulfur solubility increases with increasing temperature and pressure, especially when the pressure is greater than 30 MPa. Moreover, the H2S content in sour gas mixtures is also an important factor affecting elemental sulfur solubility. The elemental sulfur solubility increases with increasing H2S content of the sour gas mixtures. The experimental data in this paper display a consistent trend with the reported experimental data. Based on the experimental results, the chrastil-type model, Robert’s model and Hu’s model were investigated and compared. The results show that the chrastil-type model by fitting experimental data in this paper has less error and higher accuracy in calculating elemental sulfur solubility in M gas reservoir. The chrastil-type models proposed in the literature, meanwhile, are only based on the regression of specific gas components and experimental conditions, which lead to a large error in the calculation of elemental sulfur solubility of sour gas samples in this research. The research results provide important basic data and technical support for the development of M gas reservoir.

A 1980 field survey of earthquake activity near Rocky Mountain House, Alberta, using one digital and six conventional seismographs, recorded 146 microearthquakes (M ≤ 3.4) in 23 days and located 67 of them. The located events, and probably the unlocated events as well, all occurred in a small zone approximately 4 km north–south by 4 km east–west by 1 km thick, centred near 52°12.5′N, 115°15′W at a depth of 4.0 km, with an uncertainty of ±2 km on each of the location coordinates. The activity occurred below and (or) in the Strachan D-3A sour gas reservoir, which is a Devonian-aged limestone reef complex in a section of nearly flat-lying, unfaulted sediments. The earthquakes had a composite thrust-faulting mechanism with generally north-trending, intermediate-dipping planes in the presence of a regional deviatoric stress field that was horizontally compressive and oriented approximately east–west. The earthquake activity may be related to the extraction of the natural gas and related fluids from the reservoir, but the exact relationship cannot be documented at this time.The earthquake activity in the region increased dramatically after the production of gas from the reservoir began in the early 1970's. The tight cluster of activity found by the field survey suggests that all the activity in the region occurred in the same small zone but that earlier events may have been mislocated. Earthquake activity in western Alberta generally is not induced and occurs within a regional seismicity belt spatially continuous with the Intermountain Seismic Belt of the northern United States, but the earthquake activity in Canada seems to be tectonically distinct from that in the U.S.A., being characterized by thrust faulting and horizontally compressive stress.
