Hyperspectral data as a proxy for porosity estimation of carbonate rocks
نویسندگان
چکیده
Rock porosity is one of the most significant parameters in fluid-flow simulation context carbonate reservoirs. The hydrocarbon industry uses to assess production potential oil and gas environments. Traditional methods determine are limited discrete measurements generally demand extra resources associated with careful analysis logs, rock sampling laboratory analysis. This paper investigates an alternative estimate rocks using pointwise hyperspectral data machine learning. method contiguous, does not require was validated various plug samples collected from two distinct outcrops. were analysed ground-truth values for effective reflectance visible infrared regions spectra. supervised regression applied able a robust relationship between spectral behaviour characteristic features carbonate, hydroxyl, molecular water Fe/Mn. results obtained here suggest soundness indirect approach models trained achieving coefficient determination above 0.8 mean absolute deviation less than 2%.KEY POINTSHyperspectral can be used as proxy estimation rocks.All tested learners achieved R2 greater 0.7.Regularised linear porosity.Support vector achieves error 1.0249 our dataset.

Thin Sections Images Processing Technique for the Porosity Estimation in Carbonate Rocks
In present paper we used program Cluster Image which was created in Java to process thin section image of carbonate rock to estimate its porosity on image of any format and with a strong color contrast between the mineral part and pores in thin sections under polarized light. For the experiment the images of thin sections of carbonate rocks of the Carboniferous age were used. Cluster Image does...
متن کاملA Physical-based Model of Permeability/Porosity Relationship for the Rock Data of Iran Southern Carbonate Reservoirs
The prediction of porosity is achieved by using available core and log data; however, the estimation of permeability is limited to the scare core data. Hence, porosity and saturation data through the framework of flow units can be used to make an estimation of reservoir permeability. The purpose of this study is to predict the permeability of a carbonate gas reservoir by using physical-based em...

15 صفحه اولCharacterization of Bitumen Bearing Carbonate Rocks
Several countries, including Canada, contain sizeable bitumen resources in highly fractured carbonate rocks. Any possible recovery of bitumen from these reservoirs will be highly dependent on proper understanding of the rock and fluid properties and how they vary in the reservoir. These carbonates are extremely heterogeneous, and as a result proper reservoir characterization is challenging. In ...
