Some researchers have suggested that if the flowing bottomhole pressure is not lowered beyond the equilibrium pressure corresponding to the freezing point of water, then ice formation may be avoided. This argument is based on the premise that the lowest temperature would occur...

... reservoir. The simplified form of this equation for a volumetric hydrate-capped gas reservoir can be written as (Gerami et al., 2006): Equation (1) (Available in full paper) In the above equation, G p and G g are cumulative gas production and generation, respectively, and G f is the initial free gas...

... Abstract In this study, we have investigated a gas production system from methane hydrate layers using hot water injection using horizontal wells including a production well and multiple injection wells. Experiments on the gas production were performed using scaled two-dimensional physical...

Horizontal drilling was introduced in 2004 to improve water inflow, accelerate dewatering and decrease the amount of time to initial gas production. Surface footprint was also significantly...

... Abstract Gas hydrates are being considered as a future-alternate energy resource due to enormous quantities of natural gas deposition in hydrate form in the permafrost and offshore regions of the world. This study introduces an analytical numerical model for simulation of gas production...

... are critical to developing a successful commercial project. Introduction Fractured shale reservoirs include some of the oldest known oil and gas production in North America. Natural gas was produced from the Devonian shales near Fredonia, NY as early as 1821, which pre-dates any known oil production...

... dioxide and hydrogen sulphide) already governs the behaviour of these gases at temperatures above approximately 180 ° C, well below the critical point. This behaviour has been used to develop a theory of gas production in SAGD, according to which gas production in SAGD largely occurs via dissolution...

In North America, gas resource from tight sands is estimated to be around 1371 Tcf (1). Unconventional gas production was only 1 Tcf / year in the 1970s, but has increased to around 4 Tcf / year...

The implications of this work include an effect on simulation studies of bitumen production, and on the possible effect of cap gas production via the produced water. This may be an equity issue in the Athabasca...
