Study Results

Because of reservoir heterogeneity around the horizontal section of horizontal well, which makes inflow profile and pressure drop unevenly distributed in horizontal section. It is easy to cause water coning in reservoirs with bottom aquifer and affect the ultimate recovery. With the development of horizontal-well drilling and completion technology, the demand of water control increases step by step. In this paper, we used the node analysis method to establish a wellbore multiphase steady state flow model based on the equivalent filtrational resistance principle, and compared two completions’ water control ability in a case study. Results show that this model can effectively assess the effect of water control in different completion methods, and ICD can give a better water control than slotted liner completion with packer. From our results, we provide a new theoretical reference to a better choice of water-control completion for horizontal wells applications.

Throat Width

 This paper aims to conduct a series of laboratory experiments in case of steady-state flow for the new size 7 ̋ throat width (not presented before) of the cutthroat flume. For this size, five different lengths were adopted 0.535, 0.46, 0.40, 0.325 and 0.27m these lengths were adopted based on the limitations of the available flume. The experimental program has been followed to investigate the hydraulic characteristic and introducing the calibrated formula for free flow application within the discharge ranged between 0.006 and 0.025 m3/s. The calibration result showed that, under suitable operation conditions, the suggested empirical formulas can accurately predict the values of discharge within an error ± 3%.

Aquifer Test

A simple, approximate but practical graphical method is proposed for estimating the storage coefficient independently from the transmissivity value, provided that quasi-steady state flow data are available from a pumping test. In the past, quasi-steady state flow distance-drawdown data have been used for the determination of transmissivity only. The method is applicable to confined and leaky aquifers. The application of the method has been performed for various aquifer test data available in the groundwater literature. The results are within the practical limits of approximation compared with the unsteady state flow solutions.
