... DAS, flow-noise correlations could be derived. Specifically, it will be demonstrated that the flowinduced noise can be reliably predicted based on a single parameter that encompasses the impact of both flow rate (Q) and inflow geometry, where the latter is represented by the diameter of the orifice (D...

... lead to a 20-30% difference in oil recovery. Therefore, updating the viscosity distribution in the reservoirs along with the drilling activities is important. For advanced mud gas data, the ethane/iso-pentane ratio is the best parameter correlated to reservoir oil viscosity. The approach based...

... but the explosive charge was conservatively selected to reduce the risk of over-filling the bullet and compressing the core fabric. The average core lengths on Well 1 was 1.27in and 1.43in on Well 2. Although there is a positive correlation between core length and depth (Fig.8), possibly better core length...
