Abstract Fluid flow is strongly affected by fractures in unconventional reservoirs. It essential to deeply understand the characteristics with for improving production and efficiency of reservoir exploitation. The purpose this work develop an accurate numerical model evaluate transient-pressure response well intersecting fractures. meshes generated from Fullbore Formation Micro-Imager (FMI) ima...

Gas-condensate reservoirs contain hydrocarbon fluids with characteristics between oil and gas reservoirs and a high gas-liquid ratio. Due to the large gas-liquid ratio, wellhead choke calculations using the empirical equations such as Gilbert may contain considerable error. In this study, using drill stem test (DST) data of a gas-condensate reservoir, coefficients of Gilbert equation was modifi...

Finding a representative fluid in a hydrocarbon reservoir is crucial for integrated reservoir management. In this study, a systematic approach for screening and selecting consistent fluid samples in a reservoir was developed. The model integrated quality control (QC) of well conditioning before sampling, QC of PVT data, thermodynamic modeling and compositional gradient within a reservoir. Well ...

Abstract Subsurface pressure quantification is the main goal for all drilling engineers due to its vital importance minimizing costs and preventing various excavating dilemmas such as stuck pipe, pipe collapsing, lost circulation, well kick. Formation measured directly in producing hydrocarbon zones using special equipment; however, it difficult obtain pore measurements other intervals; therefo...

The drilling length is an important parameter in the process of horizontal directional drilling (HDD) exploration and recovery, but there has been a lack of accurate, automatically obtained statistics regarding this parameter. Herein, a technique for real-time HDD length detection and a management system based on the electromagnetic detection method with a microprocessor and two magnetoresistiv...
