Initial range of values tested for each parameter of three model types

ParameterRangeStep
Spherical reservoir models
Source radius (fixed and floating) (km)0.5–100.5
Source pressure (MPa)1–301
Source depth (km)2–201
Source centroid lateral location (east–north offset) (km)±101
Ellipsoidal reservoir models
Source pressure (MPa)1–301
Source depth (km)2–201
Source centroid lateral location (east–north offset) (km)±91
Horizontal (a) and vertical (b) semi-axis (km)0.5–100.5
Or
log­10e (for e, the ratio of horizontal to vertical semi-axes; fixed volume of c. 4.2 km3)−1–10.1
Double-reservoir models (fixed radius of 1 km)
Source pressure (upper and lower reservoir) (MPa)1–301
Source depth (upper) (km) Source depth (lower) (km)3–9 10–201 1
Source centroid lateral location* (east–north offset) (upper and lower) (km)±21
  • Lateral offsets are relative to the position of the SHV dome, taken as 587 990 m east, 1 847 880 m north (WGS84, UTM20Q).

  • *Two separate model runs, with fixed or free lateral centroid location, were considered.
