Abstract:
Prediction of rock fracturing capacity demands particular requirements for the exploitation of mineral resources, especially for the parameter design of conical pick performance for hard rock fragmentation, which must take into account differences in rock mechanical properties. Among these parameters, the peak cutting force (PCF) is important in designing, selecting, and optimizing the cutting head of mining equipment and a cutability index of rocks. Taking high lithological tolerance as demand traction, this study proposes a theoretical model for estimating the peak cutting force of conical p

Abstract:
The interpretation of rock lithology is inaccurate if it only uses cutting data, so it must be assisted with other data, including logging data. The purpose of this study was to determine the lithological arrangement of rocks based on cutting data and logging data and to compare the cross section results of cutting data and logging data. This study uses cutting data and logging data (gamma ray log and density log). Cutting data and logging data will be interpreted and processed into 2D and 3D sections which are corrected with topographical data including coordinates, elevation values, strike d

This study presents a comprehensive lithostratigraphic characterization of the MI Well in the Niger Delta Basin through microscopic examination of ditch cutting samples. The aim was to identify the lithological units and assess the presence and distribution of petroleum system elements. A total of seventy-two samples ranging in depth from 4500ft-11460ft (1372m-3493m) were analyzed, revealing four lithological units: sandstone, shale, sandy shale, and shaly sand. Through interpretation of the lithological log, the cap/seal rock, reservoir rock, and probable source rock units were identified. Th

Abstract:
The seismic image of deep rock, interesting for the petroleum industry, can be distorted by the heterogeneous near-surface layers, characterized by low wave propagation velocity. The conventional methods used in counteracting this effect seem less effective in complex areas with rough topography such asthose commonly found in Colombia, which are also affected by stronger tropical weathering. Characterizationof the near-surface layer was conducted in this work with the purpose to investigate these relationships. Geological and geophysical methods were applied using data from a 2D seismic survey

Abstract In the realm of oil exploration, there is an increasing demand for precise lithological analysis, particularly in the rapid and accurate identification of fine rock cutting images. Therefore, a novel rock cutting image recognition method based on the fusion of color and texture features is proposed. This method utilizes the color histogram and grayscale co-occurrence matrix techniques to extract color and texture features from target images, respectively. Compared with the traditional single-feature recognition methods, this integrated feature method can greatly improve the accuracy o

Abstract:
Abstract The task of automating the detection of lithology in drill cuttings is an essential aspect of reservoir engineering. As a wellbore is drilled, the rotating bit breaks down the rocks at the bottom of the hole, and these fragments are then transported to the surface through the drilling mud. These fragments are separated from the mud by a shaker upon reaching the surface, enabling the mud to be recycled. The leftover rock fragments, known as drill cuttings, can provide a wealth of information about the geology of the wellbore, drilling speed, and the oil and gas content in the rocks. On
