A proper understanding of reservoir fluid phase behavior is the first crucial step in the development and production of an oil/gas field. This paper addresses the challenges and errors associated with the fluid sampling that may arise before, during and after the sampling operation. For this aim, DST and PVT data of exploration and production wells of a supergiant offshore gas condensate reserv...

Based on the analysis of seepage mechanism of fracturing wells in low permeability reservoir, this paper establishes the capacity model of the vertical fractured well production under the factors of Start-up pressure gradient, pressure sensitive effect and the artificial fracture length. The numerical simulation is compiled and software calculates the capacity model by using numerical simulatio...

Reservoir depletion and subsequent CO2 injection into the depleted geological reservoir induce stress changes that may mechanically damage top seal and wells, or trigger existing faults, creating the leakage pathways for CO2 escape from the reservoir. The role of geomechanics is to assess the mechanical impact of stress changes on seals, wells and faults. Since many hydrocarbon fields are geome...

Aircraft hydraulic systems are composed of several components connected and distributed along the aircraft. Monitoring leakage of these components are time consuming tasks, and often cover only some parts of the system. The objective of this work is to present a method to estimate hydraulic leakage and recommend maintenance and servicing tasks using aircraft standard sensors such as fluid tempe...

Noble gases record fluid interactions in multiphase subsurface environments through fractionation processes during equilibration. Water the presence of hydrocarbons at acquires a distinct elemental signature due to difference solubility between these two fluids. We find atmospheric noble gas produced water is partially preserved after production and disposal unlined ponds surface. This from met...

In the enhanced geothermal system (EGS), injected fluid will induce shear sliding of rock fractures (i.e., hydroshearing), which consequently, would increase fracture aperture and improve heat transfer efficiency reservoir. this study, theoretical analysis, experimental research numerical simulation were performed to uncover permeability enhancement mechanism Hot-Dry-Rock (HDR) mass under impac...
