A multi-rate test may be characterized by a series of constant flow rates, or uncontrolled variable rate. In fact, pressure build-up testing is a special type of multi-rate well test. The flow meters can aid in the design of both kinds of tests, variable or constant flow rates, and as a direct consequence more accurate analysis and results of their interpretation can be obtained. The approach presented here is based on the assumption that the system is infinite-acting and the logarithmic approximation to the line source solution of the diffusivity equation is applicable. The pressure behaviour caused by a variable flowrate is given by the principle of superposition with time.

Hole cleaning relying on viscous fluids in laminar flow for drilling has proved to be inefficient because of the inability to rotate the string to agitate bedded cuttings. Alternatively, a high fluid flow to induce turbulent flow regime is more effective for hole cleaning, but difficult to achieve because of high friction pressures in the drillpipe. Therefore a bed of cuttings is almost always present in non-vertical boreholes. For laminar flow, the distance that a particle will travel (downstream) before it falls across the annulus clearance can be calculated using Stokes’ law and the local viscosity while flowing can also be calculated. This analysis may be easily applied to optimize mud selection and wiper trips. Applying this model to high low-shear rate-viscosity (LSRV) gels shows that they may perform well inside casing but are expected to do a poor job of hole cleaning in a narrow openhole horizontal annulus without rotation.

Every simulation study is a unique process, starting from the geological model and reservoir description to the final analysis of recovery factor optimizations. In petroleum engineering area, numerical reservoir simulators are often employed to obtained meaningful and reliable solutions for most actual cases due to extreme complexity of reservoir systems. In this work, a three-dimensional numerical reservoir simulator is developed for expansion-drive reservoirs. The governing equation is discretized using finite difference approach; conjugate gradient method with the aid of MATLAB 9.0.0R code is used to solve the system of linear equations to obtain reservoir pressure for each cell, until bubble point pressure is reached; cumulative production at bubble point is computed as sum of expansion from each cell and oil production rate is determined at each time step. The average reservoir pressure is determined as a weighted average based on the stock tank oil that is left in the reservoir, and finally the recovery factor at the bubble point pressure is computed.
