Abstract—Well logging records can help to answer many questions from a wide range of special interested information and basic petrophysical properties to formation evaluation of oil and gas reservoirs. The accurate calculations of porosity in carbonate reservoirs are the most challenging aspects of the well logging analysis. Many equations have been developed over the years based on known physi...

Manpower scheduling means assigning a work pattern (shift day) according to the wants and needs of system workforce with goal minimum cost. Many production service systems require multiple scheduling. This problem is generally NP-complete, it takes long time solve through current method. Today, several innovative methods have been proposed such problems. In this paper, simulated annealing metho...

Abstract The Mamuniyat sandstones represent the main reservoir in “A” Oil Field, NC115 Concession, Murzuq Basin of Libya. As a result, primary objectives current work are to evaluate and define Formation’s petrophysical parameters using well-logging analysis. For this study, available data from ten exploratory wells were provided. Several cross-plots used lithologic constituents fluid saturatio...

As a kind of clean energy, the exploration and development coalbed methane (CBM) are great importance significance. In this paper, CBM reservoir parameters working area in Western Guizhou Province, China, were predicted by using 3D seismic technology, sweet-spot was evaluated based on prediction results. terms data interpretation, while traditional technology is extended to study CBM, new techn...

Central Sumatra basin is located on Island, Indonesia, and considered an oil prolific that produces heavy oil. The believed to have unexplored potential. Therefore, this study aims map the potential distribution in using surface subsurface lineaments analyses interpreted from satellite imagery gravity data, assisted by well log/petrophysics analysis. A thorough analysis was conducted based surf...

Biyad Formation is mainly made up of clastic sediments that contain substantial amount of proven crude oil in the eastern Yemen. The Byiad clastic is divided into Upper and Lower Biyad clastic units. Several vertical wells have been drilled and penetrated this formation. This study is concerned with the petrophysical evaluation by means of well log data of the Lower Cretaceous rocks at the East...

The aim of this study is to investigate the feasibility underground storage gas in Um El-Radhuma formation /Ratawi field. This an aquifer consisting a high permeable dolomitebeds overlain by impermeable anhydrite bed Rus formation. Interactive petrophysics (IP), Petrel REand Eclipse 100 softwares were used conduct well log interpretation, build reservoir simulationmodel and predict behavior dur...

Pore space of tight sandstone samples exhibits fractal characteristics. Nuclear magnetic resonance is an effective method for pore size characterization. This paper focuses on characteristics from nuclear (NMR) samples. The relationship between the dimension NMR with structure and water saturation parameterized by analyzing experimental data. Based it, a characterization classification water-sa...
