Analyses of storage coefficient for a production well

الملخص EN

In case of Production or (single) well pumping tests the Storativities are overestimated, it depends on radial distance between effective well bore radius in single well test.

The objective of the paper proposed to drive the diffusion equation to find out the effective radial distance.

Applying AQTISOLVE and Aquifer win 32 software via Jacob method for well testing , we can obtain the Storativity value and the Transimissivity using specific capacity data to check the Transimissivity value .

The advantage of this method reducing the cost by having single well test (production well) without observation well.

Justification the parameters of aquifer is require because turbulent velocity and the screen of well (aquifer losses and well losses).

Application of single well test lead to understand aquifer layer and the management of reservoir.
