Selection of the most suitable drill bit type is an important task for drillers when planning new oil and gas wells. With advancement intelligent predictive models, automated selection possible using earlier drilled offset wells’ data. However, real-field well data samples naturally involve unequal distribution points that results in formation a complex imbalance multi-class classification prob...

a r t i c l e i n f o Keywords: Avoidance Bakken Grassland birds Oil development Piecewise regression Sprague's pipit Oil development in the Bakken shale region has increased rapidly as a result of new technologies and strong demand for fossil fuel. This region also supports a particularly high density and diversity of grassland bird species, which are declining across North America. We examine...

Production data analysis has extensively been applied to predicting the future production performance and field recovery. These applications are mostly on a single well basis. This paper presents a new approach to production data analysis using Artificial Intelligence (AI) techniques where production history is used to build a field-wide performance prediction models. In this work AI techniques...

in the this research, the hydrocarbon generation potential of the gadvan formation as a probable source rock was investigated in the central part of the persian gulf at the borders of iran. type and maturity level of kerogen were investigated in six wells using the results of rock-eval pyrolysis and compared with results yielded by the modelling software program known as pars basin modeler (pbm...

In the article, authors talk about ways to improve quality of core sampling from methane coal seams in Kuznetsk basin. Core is carried out at exploration wells Naryksko-Ostashinskaya square. Methane extraction remove gas seams. Moreover, can be used as unconventional energy sources. Thus, safety mining facilities increases, and we receive additional income for sale end consumers. To develop a t...

Recent coal seam gas to liquefied natural developments have revitalised the Bowen and Surat basins provided impetus explore further for plays with sufficient scale target both export domestic markets. Over last decade, several wells were drilled through Permian-age sediments in southern Basin stimulated assess commerciality of various tight formations. Thorough data collection included log, cor...

Carbon capture and storage is considered as an amelioration technique to address the increasing level of carbon dioxide in atmosphere. Depleted oil gas reservoirs are potential candidates for long sequestration captured dioxide. The huge number drilled wells these hydrocarbon around world, however, pose a threat integrity geological CO2 projects. These direct connections Earth’s surface even wh...

Abstract Nukhul Formation is one of the primary oil reservoirs in Gulf Suez Basin. Rabeh East an producer field located at southern border Suez. The present work deals with geophysical investigation using seismic lines and well log data four wells, namely RE-8, RE-22, RE-25 Nageh-1. interpreted profiles display that RE-8 Well only drilled within up-thrown side a significant horst fault block bo...

A deliverability test performed in a gas well is one of the fundamental steps to determine flow potential wells reservoir surveillance. Dynamic models need robust AOF (Absolute Open Flow), productivity index, permeability for calibration, history matching, and predictions. In this study, Pliocene sandstone was validated using “Modified Isochronal Testing” method. This study aims mitigate effort...

Geomechanical studies are very important in the development stages of oil fields to solve many problems such as wellbore instability and sand production. However, this study is not complete without availability mechanical properties rocks. These estimate from petrophysical logs based on compressional shear wave velocities. But often missing most wells, reason might be cost-saving. Therefore, ai...
