The estimation of non-stationary random medium parameters petrophysical is the key to application theory in fine seismic exploration. We proposed a method for estimating using data. Based on linear model, relationship between data and porosity, clay volume, water saturation was described, principle autocorrelation parameter were introduced this study. Subsequently, specific steps applying power...

Geomechanical characterization plays a key role in optimizing the stimulation treatment of tight reservoir formations. Petrophysical models help classify rock as conventional or unconventional type and determine hydrocarbon-saturated zones. petrophysical are fundamentally based on well-log data that provide reliable high-resolution information, used to various relationships between measured bor...

The sand intervals of the Lower Goru Formation of the Cretaceous age, widely distributed in the Middle and Lower Indus Basin of Pakistan, are proven reservoirs. However, in the Sawan gas field of the Middle Indus Basin, these sandstone intervals are very deep and extremely heterogeneous in character, which makes it difficult to discriminate lithologies and fluid saturation. Based on petrophysic...

In our last SEP report, we introduced an AVO dataset consisting of seismic, petrophysical and well-log information which was provided by Mobil as part of an AVO workshop (?). The prestack seismic data are heavily contaminated by free-surface and water-bottom multiple reflections, and thus represent a challenge for true-amplitude processing. We described our preliminary preprocessing work and di...

Although shale gas plays have been in the spotlight recently, natural gas in tight sandstones is actually also an important hydrocarbon resource. In many cases, tight gas sandstone resources can be developed more easily than shale gas reservoirs as the rocks generally have higher quartz content, and are more brittle and easier to complete for production. This chapter first gives an overview of ...

The work is carried out approbation of the algorithm for complex interpretation geophysical data using classification algorithm. Distributions by class are obtained and compared with petrophysical materials from published sources. This geological composition studied area obtained. applicability this approach integrated shown, including low-level areas a structure.

In this paper, I introduce a new mathematical model of the IP effect based on the effective-medium theory, which provides a unified mathematical method to study heterogeneity, multi-phase structure, and polarizability of rocks. The geoelectrical parameters of a new composite conductivity model are determined by the intrinsic petrophysical and geometrical characteristics of composite media: mine...
