Tight oil reservoirs have been a concerned of the industry due to their substantial influence on production. Due poor permeability, numerous problems are encountered while producing from tight reservoirs. Petrophysical and geomechanical rock properties essential for understanding assessing fracability reservoirs, especially enhance permeability. In this study, Saadi B reservoir in Halfaya Iraqi...

The spatial distribution of petrophysical properties within the reservoirs is one of the most important factors in reservoir characterization. Flow units are the continuous body over a specific reservoir volume within which the geological and petrophysical properties are the same. Accordingly, an accurate prediction of flow units is a major task to achieve a reliable petrophysical description o...

This paper presents an innovative solution for estimating the proximate parameters of coal beds from the well-logs. To implement the solution, the C# programming language was used. The data from four exploratory boreholes was used in a case study to express the method and determine its accuracy. Then two boreholes were selected as the reference, namely the boreholes with available well-logging ...

Abstract The present work aims to investigate the reservoir characterizations of Lower Cenomanian Baharyia Formation by creating isoparametic maps calculate petrophysical parameters and detect favorable parts for oil accumulations using available well logging data. is one main hydrocarbon sandstone reservoirs in northern Western Desert Egypt. About 90% field produces form Formation. This has be...

Abstract Although reservoir characterization has been carried out by many researchers on the sedimentary package of Bengal basin hydrocarbon province, integration petrophysical and seismic sequence-based evaluation is rarely taken into account. This paper focuses identification gas zones, reserve estimation new prospects in Srikail field within eastern fold belt integrating four wireline logs 2...

more often clay matrix is the major factor to reduce the porosity and permeability in sandstone facies. consequently determination of clay minerals is of prime importance in reservoir quality assessment. the present study aims to identify four different types of clay mineral namely kaolinite, illite/cholorite, halloysite, and montmorilonite from petrophysical logs (pls) using cation exchange ca...

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 ...

In this paper, 2D seismic data and petrophysical logs of the Pabdeh Formation from four wells of the Mansuri oil field are utilized. ΔLog R method was used to generate a continuous TOC log from petrophysical data. The calculated TOC values by ΔLog R method, used for a multi-attribute seismic analysis. In this study, seismic inversion was performed based on neural networks algorithm and the resu...
