Comment:
Recovery pressure (Prec) as maximum pressure determined by use of a digital pressure sensor connected to the DAPC pressure chamber.
Volumes of dissolved and non-dissolved methane VdissCH4, VnondissCH4, hydrate volumes, and hydrate fractions are in terms of core volume (Vc)/pore volume (Vp) below the sulfate zone (SZ)
