... is the primary choice for data acquisition in these high-angle development wells. Abrar et al. (2018) also presented the options for methods of fluid identification in the Kujung formation that are available by using LWD tool conveyance. A similar data acquisition selection process was conducted...

... column is shown in Fig 14 . In 2003 a pilot vertical well was drilled to make a high-angle cuasi- horizontal well whose objective was to develop areas with remaining oil and to avoid production problems due to high water volumes of previous hydraulically fractured vertical wells. From the log...

... factor. This inversion method takes the viscoelastic impedance inversion algorithm as the basic framework which is informative and has high fidelity. Synthesizing geological, well logging and seismic data, we can calculate the parameters reflecting lithology and fluid properties by this method. We take...

.... Tectonic fractures are mainly high-angle fractures and intersect with bed fractures. The identification of the imaging logging data in the study area shows that the bed fractures are significantly higher than tectonic fractures. Structural fractures are mainly high-angle fractures and intersect with bed...

... Effective fluid bulk modulus can reflect reservoir fluid content more exactly. Therefore, we applied joint inversion of PP and PS wave in synthetic model of well logging. From real log data, we used equation (5) and (6) to calculate ppR and PSR of angle 0 to 30. Then, ppR and PSR SEG New Orleans Annual...
