The system has a device in a portion of a conveyance mechanism comprising a cylindrical housing with at least one sensor that tracks a position of the portion during a drilling operation, the device being configured to obtain a plurality of drilling parameters, and a control system coupled to the device and configured to perform at least one reservoir simulation, and prepare a plurality of required parameters while drilling. The device uses an optimization box to simulate increasing an angle between a drilling direction and a maximum horizontal stress by calculating a minimum mud pressure required to prevent borehole collapse. The control system generates an engineering curve representative of each angle simulated and a corresponding mud weight or pressure, and the device and the control system identify an optimal direction corresponding to a minimum drilling mud pressure parameter.

Abstract: Examples of methods and systems for predicting a predicted breakdown pressure for a wellbore are disclosed. The methods include obtaining a set of wellbore length compensating breakdown pressure correction curves and obtaining an approximate breakdown pressure, wherein the approximate breakdown pressure is based, at least in part, on measurements taken in a laboratory-scale wellbore. The methods further include determining a predicted breakdown pressure from the approximate breakdown pressure and the set of wellbore length compensating breakdown pressure correction curves, where the predicted breakdown pressure predicts the breakdown pressure of a reservoir-scale wellbore.

Abstract: Methods and systems include obtaining a correlation and obtaining a salt sample from a salt formation. The methods and systems further include, for each of N cycles, exposing, using an injection system, the salt sample to an nth amount of a gas and determining an nth value of a property by subjecting the salt sample, using an atomic force microscopy (AFM) system, to an AFM test. The methods and systems further include determining a relationship using the N values of the property, determining, using the correlation, a macroscale relationship based on the relationship, and generating a fit constitutive model by fitting the constitutive model to the macroscale relationship. The methods and systems include generating a model of a salt cavern within the salt formation based on the fit constitutive model and designing a salt cavern for withdrawal cycles of the gas using the model.

Abstract: A method for evaluating potential damage to a cement sheath in an underground gas storage facility during an earthquake. A ground surface earthquake (EQ) wave is obtained on which a deconvolution analysis is performed, producing a subsurface EQ wave. Static and dynamic mechanical properties of a casing-cement-rock well system are obtained, and a computational model of the underground gas storage facility is generated. A gas pressure value is applied to the model, and, after boundary conditions are applied, a static equilibrium state is simulated. The subsurface EQ wave and boundary conditions are applied to the model, and, based on the gas pressure value, a dynamic seismic event is simulated. Based on the effect of the seismic simulation on the integrity of the underground gas storage facility, at least one parameter related to the operation of the underground gas storage facility may be adjusted.
