Research ArticleOpen accessPhrase in the titleAutomatic Measurement of Drilling Parameters to Evaluate the Mechanical Properties of SoilsDaniele Pettinau, Pierpaolo Oreste, Marilena Cardu, Davide GuidarelliAny underground work, carried out either to perform excavations, should be based on detailed knowledge of the geological, hydrogeological and geomechanical conditions of the underlying materials. The continuous automatic diagraphy is a test that consists in the continuous surveying of drilling parameters, with total destruction of the core, which can be used, together with geognostic probing surveys and a detailed … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 17 Jun 2013 · 7,546 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleEffect of Parameters of Selection and Replacement Drilling Bits Based on Geo-Mechanical Factors: (Case Study: Gas and Oil Reservoir in the Southwest of Iran)Arzhang NabilouThe purpose of the present study was to explore the effect of drill bit selection parameters on enhanced oil and gas recovery fin Iranian oil and gas fields. In this study, many methods and parameters were discussed. These parameters are practically tested on many wells in southwestern field of Iran. Out of common drill bit selection methods, length unit drilling … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 9 May 2016 · 8,362 accessesView PDF Cite

Research ArticleOpen accessIn the abstractReal-Time Simulation Method Using Monte Carlo and Clustering Algorithms: A Case Study Covering Drill Bit WearRodolfo Wilvert Reitz, Paulo José de Freitas FilhoMinimization of the cost of drilling an oil well is primarily achieved by reducing the operation completion time, which in turn can be achieved by increasing the Rate of Penetration (ROP). The ROP is the result of a combination of factors, such as lithological formation, operational parameters and bit wear. This paper addresses bit wear during drilling, using a method … …Journal of Computer Science, Vol. 14, Issue 2 · 27 Feb 2018 · 8,210 accessesView PDF Cite

Research ArticleOpen accessIn the abstractESTIMATION OF AQUIFER PARAMETERS IN ERHO, NIGERIA USING THE COOPER-JACOB EVALUATION METHODOchuko Anomohanran, Ruth E. Iserhien-EmekemeThe aim of this study was to determine the aquifer parameters in Erho, Nigeria. This was carried out by drilling three test wells and three observation wells in the study location. Water was pumped from the test wells at a constant rate while the drawdown in the observation wells was determined as a function of time. The data obtained were … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 12 Nov 2014 · 6,910 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA COSSERAT-TYPE PLATE THEORY AND ITS APPLICATION TO CARBON NANOTUBE MICROSTRUCTUREAbdellatif Selmi, Hedi Hassis, Issam Doghri, Hatem ZenzriThe predictive capabilities of plate and shell theories greatly depend on their underlying kinematic assumptions. In this study, we develop a Cosserat-type elastic plate theory which accounts for rotations around the normal to the mid-surface plane (so-called drilling rotations). Internal loads, equilibrium equations, boundary conditions and constitutive equations are derived. The case of a Single Walled carbon Nanotube (SWNT) modelled … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 12 May 2014 · 6,930 accessesView PDF Cite
