Production data analysis techniques have been widely used for estimating reservoir properties such as gas in place and average pressure. Knowledge of this information is crucial for proper reservoir management. The present study discusses the roadmap, challenges and uncertainties for analyzing production data in an Iranian gas-condensate offshore field. This work is an integrated study in...

abstract at present study constant rate of strain (crs) consolidation under non-darcy condition was investigated. in this study a governing conditions of drainage pore water were investigated using proposed equation. the crs experiments under different rates of strain were conducted on different soil samples. results these experiments and there comparison with proposed equation showed that flow...

Since Dual Gradient Drilling (DGD) is a new and advanced drilling technology, currently its methods, procedures, simulations and experiments are still underdeveloped. It requires more study, research and advanced methods on DGD systems. The motivation of the paper is to study DGD systems, design good operational drilling parameters, and work on automated DGD systems to further realize safe and ...

The hole drilling method is based on the measuring of the surface relaxed strains when a small hole is drilled on the examined component. From the relaxed strains, measured generally by using special strain gage rosette, the residual stresses is computed by using proper influence coefficients, provided also by the ASTM E837-08 standard. Such influence coefficients are obtained by numerical simu...

In this paper, the stress concentration around a hole in the single layer composite materials with long fibers is examined. The single layer has an infinite length, limited with and instant thickness and is loaded by a constant tension force p at infinity. The width of the lamina is considered to be finite and bears a hole as a defect. Due to presence of excessive shear stress in the matrix bay...

In this paper, we will analyze a five-dimensional Yang-Mills black hole solution in massive gravity's rainbow. We also investigate the flow of such with scale. Then, discuss scale dependence thermodynamics for hole. Also, study criticality extended phase space by treating cosmological constant as pressure solution. Moreover, use partition function to obtaining corrections system and examine the...

After hydraulic fracturing, some treatments intended for production enhancement fail to yield predetermined effects. The main reason is the insufficient research about fracture propagation mechanism. There compelling evidence that I-shaped fracture, two horizontal fractures at junction of coalbed and cover/bottom layer, one vertical in have formed part after fracturing. Therefore, this paper ai...

In this paper, a new family of Hawking-Page transitions, i.e., transitions with reentrance and triple point, is introduced for the first time by investigating transition hyperbolic AdS black holes in extended thermodynamics Gauss-Bonnet gravity. The reentrant composed two high low temperature, point corresponds to small hole, massless large hole phases all coexisting. We discuss temperatures br...

The high-Tc cuprate superconductors are characterized by a quasitwo-dimensional layered structure where most of the physics relevant for high-Tc superconductivity is believed to take place. In such compounds, the unusual dependence of critical temperature Tc on external pressure results from the combination of the nonmonotonic dependence of Tc on hole doping or hole-doping distribution among in...
