Planning and Interpretation of Pumping Tests, Well Efficiency and Slug Tests

Aquifer tests are procedures that provide essential information for the characterization of the underground environment such as hydrodynamic parameters, the type of aquifer evaluated, the performance of pumping wells and their potential impact on the aquifer.

In this course, participants will learn to plan and interpret data from different types of tests, including slug tests, pumping tests and aquifer tests with multiple observation wells. Through exercises, they will analyze data obtained from these tests using different methods using the AquiferTest software. They will also learn to extract information from the tests, in addition to the hydrodynamic parameters, relevant to the characterization of the evaluated aquifer.

The topics included in this course are:

– Calculation of relevant hydrodynamic parameters;

– Determination of the type of aquifer based on the results of the tests;

– Different methods used in the interpretation of the test results;

– Performance evaluation and pressure loss in wells.

Instructor: Danilo Almeida

Geologist graduated from the Federal University of Minas Gerais. He acted as a consultant performing mathematical modeling of aquifers, springs registration and lowering water level projects for mining, with a focus on drainage and also on the possible impacts on surface and underground water availability. After a few years he joined Companhia Vale, acting as a hydrogeologist responsible for lowering the water level at the Timbopeba mine in Mariana and in the Itabira mines. He coordinated the institutional group of water resources, working to rationalize the use of water in the company’s operational units, in addition to requesting and monitoring grants. He represented the company on a river basin committee, with direct involvement in legal issues related to water use.
