‎A conditional test based on quadratic form using type-2 censored sample for testing exponentiality against Weibull alternative is proposed‎. ‎The simulated percentage points and powers are given‎. ‎The proposed test performs well for identifying Weibull DFR alternative even for small sample‎. ‎An example is also given.

This paper presents a new semi-analytical solution and the related methodology to analyze pressure behavior of multi-branch wells produced from natural gas hydrates. For constant bottom-hole production, transient flow is obtained by Laplace transforms. The interference among various branches investigated using superposition principle. A simplified form proposed model validated published analyti...
