Abstract As an important unconventional resource, shale gas can alleviate energy shortage, and its efficient development ensures the long-term growth of oil gas. The prediction production levels estimated ultimate recovery with high accuracy is necessary for development. Conventional methods are widely applied in industry owing to their simplicity effectiveness; however, none them accurately pr...

Many musical instruments have interfaces which emphasise the pitch of the sound produced over other perceptual characteristics, such as its timbre. This is at odds with the musical developments of the last century. In this paper, we introduce a method for replacing the interface of musical instruments (both conventional and unconventional) with a more flexible interface which can present the in...

A novel computationally highly e cient realization of sharp symmetrical bandstop FIR lter is proposed. The new structure is derived using the frequency-response-masking technique, where the bandedge-shaping lter is derived from half-band lter by substituting each delay of the half-band lter by M delays. The masking lters are unconventional. They are quadrature lters derived from linear combinat...

In this paper, based on error correction model by using panel data, an empirical analysis of demand for international reserves for 16 Islamic countries is investigated. Besides addressing conventional issues, the model explicitly incorporates the impact of expected export revenues and the impact of the exchange rate system on reserve demand. The results reveal that, short run money market diseq...

the purpose of establishing foreign reserves account in iran was mainly to secure iran's economy from the oil's price changes. it was to compensate for oil price reduction. but foreign reserves account withdrew excessively and did not allocate it optimally. that's why; it went for away from its practical purpose. this study focuses on the use of official assessment pattern to rev...

S tight reservoir is rich in oil and gas has good development potential. However, the lacks physical property, strong heterogeneity, lithology complex formation conditions, fracturing operation characterized by lack of fracture complexity difficulty initiation. For geological characteristics difficulties reconstruction, we actively follow principle fracture-controlled reserves, broaden understa...

As an unconventional clean resource with huge reserves and a wide distribution, natural gas hydrates (NGHs) have good application prospects. However, due to limited understanding available production technology for NGHs, there is still large gap between current tests commercial exploitation. A breakthrough in reservoir stimulation technologies key realizing the industrialization of NGHs future....
