Well Log Evaluation

The typical characteristics of carbonate reservoir is heterogeneous. The reservoirs were deposited in slope of marginal neritic carbonate plat form and marginal reefs in Middle East Oil Field. The vuggy carbonate reservoir pore systems include intergranular pores, mould pores, intercrystal pores, micropores and dissolution fracture. I t can be divided into separate vugs and touching vugs on the basis of vug interconnection. The goal of well-log evaluation is to describe the spatial distribution of petrophysical parameters, such as porosity and permeability. Well-log evaluation and core analyses provide quantitative measurements of petrophysical parameters in the vicinity of the well bore. The key for quantifying physics models is buildup the relationship between the log data and the core analyses result. The purpose of reservoir evaluation is to use the Interactive Mineral Solver module of Interactive Physics software to solve for mineralogy, porosity and permeability. The result of the analyses shows that calculated parameters has high coherence with core sample test. For vuggy carbonate reservoir evaluation, It shows that accurate values of physics parameters can be predicted using selected module in well-log data processing and interpretation.

In order to explain the creation of OPEC, Chapter 2 describes the spread of protests in the oil fields as well as the rise of nationalism in the Arab world, together with the radicalization of Venezuelan politics at the end of the 1950s. It explains in detail the organization of the first Arab Oil Congress in Cairo in 1959, the emergence of a group of oil technocrats in the Middle East and then the creation of OPEC in Baghdad in September 1960. The chapter further explores the nature of OPEC showing why, contrary to common beliefs, it cannot be defined as a “cartel,” while analyzing at the same time the first “operative” resolutions it approved in 1962.

Porosity And Permeability

The evaluation of shaley formations has long been a difficult task. Presence of shale and shale types in some of the Iranian formations are one of the most important factors. Shale types have to be considered, because existence of shale reduces, porosity and permeability of the reservoir to some degree. Shale Distributed in formations in three basic types, Dispersed, Laminar and structural. Each of these shale types has different effect on porosity, permeability and saturation. Dispersed shale reduces porosity and permeability to a great degree, but, laminar shale and structural shale have little effect on petrophysical parameters. In this investigation, shale types, Shale volume and effective porosity of Kangan Formation have been determined from well log data and compared with crossplotting. In other words, a triangle Density-Neutron cross-plot is used to determine above parameters. The area of study lies in central oil fields of Iran, where one of the well is used (Tabnak Well C). Tabnak Well C selected to study Kangan Formation from Iranian oil field, in Pars onshore. This study illustrates that distribution of shale types in Kangan Formation is mainly dispersed shale with few of laminar shale, and percentage of effective porosity (φe) decreases with increasing depths for Kangan Formation.
