Exploration Technique Information
Exploration Group: Downhole Techniques
Exploration Sub Group: Well Testing Techniques
Parent Exploration Technique: Downhole Techniques
Information Provided by Technique
Lithology: Enable estimation of in-situ reservoir elastic parameters
Stratigraphic/Structural: Fracture distribution, formation permeability, and ambient tectonic stresses
Hydrological: provides information on permeability, location of permeable zones recharge rates, flow rates, fluid flow direction, hydrologic connections, storativity, reservoir pressures, fluid chemistry, and scaling.
Thermal: Temperature variations with time

Extrapolate the true temperature of formation

Well Testing Techniques:
Tests conducted on a well to learn about the reservoir conditions, estimate the wells production/injection potential, and quantify the overall resource.

Introduction
Property "IntroText" (as page type) with input value "Well testing procedures are carried out on all newly drilled wells to determine the characteristics of the well and the formations it passes through. Most often the main goal of the well tests is to determine the productivity potential of a new well. Well testing involves an array of measurements and multiple types of downhole instruments for gathering information on the well characteristics." contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.

Use in Geothermal Exploration
Property "GeoUse" (as page type) with input value "Well tests are conducted to quantify well characteristics, production potential, and reservoir properties. Well tests are essential for exploration and production drilling, well maintenance, and geothermal field management. The tests ultimately help in optimal and sustainable utilization of the geothermal resource." contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.

Field Procedures
Well testing involves lowering numerous types of sensors down the well. Most often a well logging truck equipped with a wireline winch is used.

Best Practices
Well tests are normally conducted upon completion of drilling, but before removal of the drill rig so that the drill rig pump can be used for some of the tests.
