+ | '''Estimation and modelling of reservoirs properties through seismic attributes and geostatistics in gas fields, southern Spain. SOVG, XIV Venezuelan Geophysics Congress''' | ||
+ | |||
+ | I was co-author of a paper published in the XIV Venezuelan Geophysics Congress, in 2008. In this paper is performed a study of Seismic reservoir characterization (it's when you use seismic data for the estimation of rock properties). We used geostatistics to integrate seismic data and well logs. | ||
+ | |||
+ | Also, because in this area we found clear amplitude anomalies, we analyze the origin of the anomalies in one of the reservoirs in this area. | ||
+ | |||
+ | There are many methods trying to find a relationship between seismic attributes and well logs. The most basic method would be to plot a seismic attribute against a rock property and make a linear regression to find a relationship between the seismic attribute and the rock property. | ||
+ | |||
+ | The geostatistical methods are much more complex than linear regression but they are more reliable. | ||
+ | |||
+ | The attributes we used were: the instantaneous amplitude, amplitude RMS, instantaneous frequency and phase. | ||

El modelo mostrado en la Figura 7 (a) exhibe el efecto de máxima entonación a un espesor de aproximadamente 7 m; esto implica que nuestro yacimiento no es lo suficientemente espeso como para poder diferenciar la reflexión del tope y la base del mismo, produciéndose una superposición de ambas reflexiones. Este modelo comprueba la hipótesis de un incremento de las amplitudes sin relación alguna con la presencia del gas. | El modelo mostrado en la Figura 7 (a) exhibe el efecto de máxima entonación a un espesor de aproximadamente 7 m; esto implica que nuestro yacimiento no es lo suficientemente espeso como para poder diferenciar la reflexión del tope y la base del mismo, produciéndose una superposición de ambas reflexiones.
