... Abstract Downhole temperature monitoring, either by production logging or fiber-optic sensors, has been used in many applications for production/injection/stimulation diagnosis and design optimization. To quantitatively generate flow profiles at downhole conditions, we need theoretical models...

... Abstract The presence in the outflow of sand or minerals coming from the reservoirs is of course undesired, and generates a series of technical challenges and threats to installations. Sand diagnosis (through conventional acoustic methods) is generally a frustrating process, with frequent...

... and transmission of the surface dynamometer card. Besides the diagnosis of downhole issues, some new research has expanded the application of dynamometer cards. For example, some typical applications include acquiring pump inlet pressure from dynamometer cards ( Rowlan et al. , 2011 ; Ahmed and Ghareeb 2012...

... Abstract Downhole temperature measurements is one of the solutions to understand downhole flow conditions, especially in complex well/reservoir domains such as multi-stage fractured horizontal wells. In the past, models and methodologies have been developed for fracture diagnosis for multiple...

...Wellhead Pressure Buildup Diagnosis Model Development Once the ESP suffers problems, the pressure buildup curve appears different and deviates from the one in normal conditions. Therefore, the analysis of wellhead shut-in pressure buildup should be a practical diagnosis of ESP malfunction...

... distribution from the temperature model presents consistent trend with PLT measurement. Fracture diagnosis is more sensitive to the fluid entries (fracture locations) and less sensitive to the influence of multiphase flow inside the wellbore when compared with PLT tools. production control hydraulic...

... Abstract Although various logging challenges in highly deviated and horizontal wells have been addressed in many previous studies, only a few investigations have focused on emulsion diagnosis and multiphase production log (MPL) solutions in such difficult conditions. The emulsion discussed...

An integration of these experiences at a corporate level was decided and in November 2005, a pilot project was kicked-off to set-up a Well Performance Monitoring tool (WPM). The Beta...

.... The concept is called Geosteering Diagnosis. We identify a monitored trajectory as composed of a real-time and a project-ahead section. The bit and the MWD/LWD sensors are monitored objects attached to the trajectory. A number of targeted objects (i.e. horizons, contacts, faults, targets, planned...
