“…Meanwhile, there is equal importance applying these deterministic models into the unsampled locations or points for uncertainty analysis, serving as both prediction tools and inspection tools at the same time. Take physical property (e.g., porosity and permeability) modeling as an example; all types of data including those obtained from production sites and laboratory tests are analyzed in order to find the internal mathematical relationships between well logging curves and rock physical properties (Qi et al 2007;Kohshour et al 2013;Nazarpour et al 2014), and the electrical logs are also used for fluid saturation explanation such as oil saturation and water saturation with the help of reservoir engineering methods. For example, Masoudi et al applied Archie equation to figure out the relationship between electrical resistivity logs and water saturation (Masoudi et al 2011).…”

“…Borgomano pointed out that the challenge of well correlations is to relate the heterogeneities measured at core and well scales to the spatial heterogeneities at reservoir and flow unit scales (Borgomano et al 2009). 3D geological modeling technology makes use of all the well logging curves not only to preserve the heterogeneity of the tested wells but also to predict certain parameters of flow units with no data (Qi et al 2007;Kohshour et al 2013). Reservoir parameters can be considered explanations from well logs and certain mathematical relationships can be drawn through analysis.…”

Geostatistical modeling for fine reservoir description of Wei2 block of Weicheng oilfield, Dongpu depression, China

et al. 2015

The Wei2 block of Weicheng oilfield is characterized by complicated structure mainly caused by high degree of fault development. Multiple reservoir types are found in this block and the reservoir heterogeneity is severe. The oil and gas reservoirs have already stepped into the stagnant stage of a great water-cut degree together with a rapid production decline rate. Thereby, both stabilizing the oil and gas production and optimizing adjustment for further exploitation make it urgent for geomodelers to build a useful model to predict the inter-well parameters and the distribution of the remaining oil and gas. A three-dimensional geological model established with the help of stochastic modeling technique may provide a perfect window and carrier for fine structure interpretation and reservoir heterogeneity description, compared with a traditional two-dimensional model. Hence, based on stratigraphical layering points, significant surfaces and fault points as well seismic interpretation, an integrated structure model is developed. Using the truncated Gaussian simulation and taking the existing geological maps as references, the sedimentary microfacies model was successfully constructed. Through the use of sequential Gaussian simulation method and the facies-controlled modeling method, the reservoir physical properties are populated. Meanwhile, the comparison between facies-controlled and non-facies-controlled property models indicates that the former is more loyal to previous researching and the representation of heterogeneity is ideal. Finally, the ideas of sample density and reserves fitting are proposed to evaluate the practicability and accuracy of the property models.

The knowledge of the behavior of pressure, flow rates and flow patterns during displacement of the fluid from the wells to the production lines is critical for the oil industry. The choke appears in this context as a device that imposes a restriction on the flow line and it is generally located between tubing and the discharge line. It not only protects surface equipment and provides controlled back pressure in the production line, but it is also used to control and optimize production. This work aimed to elaborate an Excel® spreadsheet to analyze the performance of chokes with single -phase oil flow. The equations found in the literature were implemented in the program and the data from a well were used to show their application. The spreadsheet enabled the calculations to be performed quickly and straightforwardly. It could be observed from the results an agreement with those found by analytical solution. KEYWORDS: chokes, single phase flow, oil production. SIMULAÇÃO DA QUEDA DE PRESSÃO EM CHOKES DE PRODUÇÃO DE ÓLEO RESUMONa indústria do petróleo, é fundamental conhecer o comportamento da pressão, vazão e padrões de fluxo durante o escoamento dos fluidos nas tubulações. O choke é um dispositivo que impõe uma restrição ao fluxo, e geralmente, está localizado entre a coluna e a linha de produção. O uso desse dispositivo protege os equipamentos de superfície por meio do controle da vazão e da pressão. Este trabalho teve como objetivo a elaboraração de uma planilha em Excel® para análise da queda de pressão em chokes de produção de óleo. As equações encontradas na literatura foram implementadas no programa e os dados de um poço foram usados para mostrar a aplicação do simulador. A planilha permitiu que os cálculos fossem realizados de forma rápida e prática. Os resultados encontrados na simulação estão de acordo com os obtidos na solução analítica do caso estudado. PALAVRAS-CHAVE: chokes, fluxo monofásico, produção de óleo.

“…It is obvious that the development of new efficient types of beds and technologies of composing soil properties improvement is possible only based on detail studying of deformation processes under loading, by soil mechanics methods and further technologies validation of their mass construction [15][16][17][18][19]. There are various design solutions and processes aimed to reduce heat losses in oil and oil products transport and storage [20][21][22][23][24][25][26][27][28]. As a rule, they require additional energy consumption and specialized equipment.…”
