... Abstract This paper presents the case studies of the reservoir performance while under-balanced drilling. The increase of the length of the well bore provides a unique transient effect that, with an appropriate mathematical model, some reservoir parameters can be obtained. The mathematical...

... Abstract This paper set up a mathematical model of three-dimensional transient flow to describe the pressure behavior for horizontal well with wellbore storage and skin effect in naturally fractured infinite and box-shape-bounded reservoirs. On the basis of obtaining solutions of mathematical...

... Abstract Hydraulic fracturing of low permeability reservoirs with multiple fractures is an effective stimulation treatment in the serial techniques of horizontal well production. The comprehensive mathematical model of predicting the production performance of a hydraulically fractured...

... Abstract A newly developed mathematical model has been used for formation damage analyses of two hydraulically fractured horizontal wells in the Daqing field, China, and twelve vertical wells in the naturally fractured reservoirs of the Spraberry Trend Area, West Texas. Application...

... Abstract A mathematical model is developed in order to evaluate the productivity ofmultilateral completions. The model may also be used to understand and discernthe pressure behaviour of multilateral completions. The ability to incorporatethe location of each lateral rigorously is the unique...

... with a peripheral aperture for solids removal, can undertake concurrent three phase separation of liquid-solid-liquid. This hybrid hydrocyclone is referred to in this study as the Concurrent Three-Phase (CTP) separation hydrocyclone system. A mathematical model based on the CTP concept and its hydrodynamics has...

... to assemble and collect the data. Therefore, reservoir simulation is often impractical for small fields. This paper presents the development and results of a comprehensive and rigorous material balance mathematical model which simulate an oil reservoir bounded by a gas-cap and a finite aquifer. The model...

... Abstract The importance of accurate reservoir description is illustrated using reservoirstudies of various pools in Alberta. Special emphasis is placed on reservoirdescription for mathematical models. Studies show that deficiencies in certainbasic data, often considered to be of minor...
