“…A rough estimation of amount of methane is done in (Gerivani and Gerivani, 2015). According to their calculation in Gas Hydrate Stability Zone (GHSZ) in Absheron region, which is 100 km away from Baku, with thickness of 200 m extending for 10 km and only 5% of the sediments volume being composed of gas hydrates is assumed.…”

Some unique characteristics of the Caspian Sea, especially the South Caspian Sea, such as low geothermal gradient, rapid sedimentation, a great number of mud volcanoes, suitable temperature and pressure conditions make it worth for exploration of gas hydrate potential. In this study, gas hydrate potential of the South Caspian Sea is determined within the targeted coordinates, 39N -50E, 40N -50E, 40N -52E and 39N -52E, which includes Absheron area and several mud volcanoes but excluding the parts shallower than 100 m water depth. The total area is subdivided into three categories, namely gas hydrate concentrated zone, gas hydrate bearing zone and around craters of mud volcanoes. The mean of accessible resource volume is estimated as 2.1810 12 , 1.5310 14 , 1.6510 10 Sm 3 of gas for these three zones, respectively. The mean of total accessible resource volume of targeted areas is estimated as 1.7510 14 Sm 3 of gas.

Steam Assisted Gravity Drainage (SAGD) is a common thermal recovery technology that uses steam to heat and extract oil from bitumen reservoirs. It consists of an upper horizontal injector and a lower horizontal producer. Varied lateral extent, thickness, and frequency of shale layers can be observed and these shale layers can substantially impair the pay zone's vertical permeability and slow down the SAGD process by interfering with the flow of steam and oil. Henceforth, identifying shale problems and finding solutions to them has become critical in SAGD production.This study investigated shale issues in the SAGD process from the simulation perspective. Hypothetical shale cases were built in SAGD simulation models using the CMG STARS simulator. In addition, the vertical well pair spacing in the SAGD simulation model was changed to test it as a remediation technology to reduce the negative shale impact on the steam chamber, and the SAGD performance.
