Horizontal wells can significantly improve the gas production and are expected to be an efficient exploitation method for industrialization of natural hydrates (NGHs) in future. However, near-wellbore hydrate is highly prone decomposition during drilling process, owing disturbance aroused by factors such as fluid temperature, pressure, salinity. These issues result engineering accidents bit sti...

Reservoir simulations are used to forecast the long-term gas production from hydrate reservoirs. In present work, we explore different well placements and configurations analyze strategy for an oceanic, unconfined, class-2, reservoir using in-house three-dimensional finite volume simulator. past, depressurization in unconfined class-2 reservoirs, isolation of aquifer zone by placement is sugges...

There are numerous risks associated with mining and owning cryptocurrencies, exploring producing oil natural gas highly risky, costly, controversial. A marriage of digital has reduced the major costs for both crypto miner petroleum industry. On one hand, requires an enormous amount electricity, which is not environmentally friendly. other when drilling resources, often discovered, but due to a ...

The process of formation and deposition gas hydrates on the walls a well during its joint operation with reservoir heat exchange environment is modeled. problem reduced to solving differential equations describing non- isothermal flow an imperfect both in porous medium well, propagation rocks appropriate coupling conditions. It shown that for wells temperature significantly exceeding equilibriu...

The main challenge facing the oil industry is to reduce development costs while accelerating recovery with maximizing reserves. One of the key enabling technologies in this area is intelligent well completions. Intelligent well technology (IWT) is a relatively new technology that has been adopted by many operators in recent years to improve oil and gas recovery. Intelligent well completions emp...

the effect of three levels (0, 28.65, 57.31mg /200mg substrate) of golpar (heracleum persicum: hp) on in vitro rumen ecosystem and on methane production was assessed. gas production (gp) was recorded from 1 to 54h past of incubation. the parameters studied were in vitro gas production (ivgp), methane production, ammonia-n concentration (nh3-n), in vitro organic matter degradability (ivomde), pa...

A proper understanding of reservoir fluid phase behavior is the first crucial step in the development and production of an oil/gas field. This paper addresses the challenges and errors associated with the fluid sampling that may arise before, during and after the sampling operation. For this aim, DST and PVT data of exploration and production wells of a supergiant offshore gas condensate reserv...

The objective of this work is to develop deep theoretical methods that are based on the solution of the integral boundary layer equations for investigating film cooling in liquid rocket engine. The integral model assumes that heat is transferred from hot free stream gas to the liquid film both by convection and radiation. The mass is transferred to the free srteam gas by the well-known blowing ...
