Seasonal storage of heat in shallow aquifers for increasing the efficiency of geothermal energy systems requires a proper monitoring strategy. We expanded our earlier work on harmonic pulse testing (HPT) to incorporate the effect of a temperature front moving into the reservoir due to injection of hot (or cold) water. Our analytical solutions...

Harmonic Pulse Testing (HPT) has been developed as a type of well testing applicable during ongoing field operations because a pulsed signal is superimposed on background pressure trend. Its purpose is to determine well and formation parameters such as wellbore storage, skin, permeability, and boundaries within the investigated volume. Compared...

Harmonic testing was developed as a form of well testing that can be applied during ongoing production or injection operations, as a pulsed signal is superimposed on the background pressure trend. Thus no interruption of well and reservoir production is needed before and during the test. If the pulsed pressure and rate signal analysis is...

For decades, well tests have been widely used in the oil industry for evaluation of well productivity and reservoir properties, which provide key information for field development and facilities design. In conventional well tests equilibrium conditions are required in the reservoir before the test. Furthermore, a single well only can be produced...

A geomechanical and fluid-flow coupled model was developed to simulate natural-fracture-network reactivation during hydraulicfracturing treatments in shale gas reservoirs. The fractures were modelled using the continuum approach in a commercial finitedifference code, labeled the "softening ubiquitous joints" model, with randomly distributed...

The economic production from shale gas reservoir depends on the success of hydraulic stimulation, which is aimed at the creation of a permeable complex fracture network. This is achieved by the reactivation of a natural fracture network; however, the reactivation may be accompanied by unwanted seismicity. Coupled modelling is required to...

We present a semianalytic method for modeling the productivity testing of vertical, horizontal, slanted, or multilateral wells. The method is applicable to both oil and gas reservoirs and automatically accounts for well interference. The use of analytic expressions ensures that short-time transient behavior and long-time semisteady-state...
