... (Tc), and extended into a generalized model to include crude oils. To address its practical applicability, the Sutton model was modified by extracting Tc from routinely measurable properties such as density and viscosity, resulted in not only improved predictive accuracy and reduced uncertainty...

... ABSTRACT Global equations for predicting GOR , API gravity and saturated viscosity from downhole testing and sampling measurements have been developed using a symbolic regression (SR) machine learning method. Nearly 700 fluid samples collected from more than 500 wells from many parts of world...

... ABSTRACT Breidablikk is a green field on the Norwegian Continental Shelf and just started the pre-production drilling of 23 wells in two structures. We have two reservoir fluid samples from exploration wells in each structure with relatively high viscosity of 4 cP and 8 cP, respectively...

An alternative explanation to support short T2 is associated with heavy oil could be that the sampling collects the lighter oil...

... Annual Logging Symposium held in The Woodlands, TX, USA June 17-19, 2019. ABSTRACT Severe biodegradation of crude oil is widely known to increase viscosity quite significantly. Water washing is known contribute to this increase under some circumstances. What has been less understood is the spatial...

... drilled in complex clastic and carbonate reservoirs. NMR logging data is paramount to the petrophysical evaluation of complex rocks such as silty sands, heterogeneous carbonates and reservoirs with variable hydrocarbon viscosity in many fields of the region. Fractionalized porosity obtained by NMR logs...

...-temperature NMR relaxometry experiments were conducted on both low- and high-frequency NMR systems to enable comparison with the logs and to obtain the highest-resolution data, respectively. It has been demonstrated that the relaxation-time dependence of light oil is proportional to viscosity over temperature...

... ABSTRACT At low viscosities, it is well known that the NMR T 1 and T 2 relaxation times of bulk fluids are inversely proportional to viscosity. However, one of the much debated mysteries in NMR relaxation measurements of crude oils is the departure from expected theoretical trends...

... Abstract Modern formation testing and sampling tools are equipped with a variety of unique sensors. The measurement data provided from the sensor modules includes, but is not limited to, temperature, pressure, density, viscosity, refractive index, sound speed and compressibility. For sampling...
