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...

Abstract Carbonate reservoirs in Iran are the most important and main sources of oil gas production. Hydrocarbon flow rates from carbonate heavily rely on development natural fractures. This study focuses role fractures reservoir quality considering Sarvak (southwest Iran) as second Iran. To identify small-scale around borehole walls, cores description image logs were utilized. Due to high cost...

Abstract The present paper introduces a Legendre polynomials based interval inversion method for processing multi-borehole logging data. allows the determination of lateral changes layer-thicknesses together with vertical and variations petrophysical parameters along 2D cross-section several boreholes. is assessed using noisy synthetic measurements model made two-layers structure related to hyd...

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.

Conventional diverting techniques may not be useful, and the use of advanced well-documented technique is needed to overcome complexity heterogeneity carbonate reservoirs. Nowadays, there have been a lot materials utilized for acid diversion. This paper aimed consider various utilization fiber-assisted self as system in acidifying One main reasons its ability uncertainty that fiber itself an in...

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...
