Drilling machine operations and characteristics, including benefits and drawbacks
Abstract: The drill press's capabilities vary depending on the machine's electronic motor, pillar diameter, spindle nose, travel, speed, and spindle speed. These are widely utilised in the automotive, printing, and engineering industries to improve the machine's consistency and tensile strength while quickly transitioning to resistive materials with high-quality results. Industries that require the mixing and grinding of solid and liquid material frequently use milling cum drilling machines.Drilling equipment is classified based …

Determination of Well Loss and Aquifer Loss of New Construction Deep Water Well at Artesian Aquifer in Khulna City, Bangladesh
Abstract: This work studied the performance of water well installed as artesian aquifer in South Western Region of Bangladesh. The main activities were known to the properties of aquifer condition on that area. Well performance was also measured after development of water well. The well performance and aquifer performance were justified by Rorabaugh’s graphical methods. The total depth of drilling was 305 m from the ground level. Drilling was completed by …

Geotechnical study of a landslide reactivation in clay soils (central Piedmont, NW Italy).
Abstract: In March 2015, exceptional meteoric events occurred in southern Piedmont caused a remarkable rise of the rivers water level of the Tanaro Basin with flooding and many landslides. The engineering geological study reported here, concerns a triggering of a previous landslide occurred in 1982 in the hills, shaped in the marine sedimentary succession (Lugagnano Clay, lower Pliocene) of the southern Asti Reliefs, near San Martino Alfieri village. Detailed geological, morphological …

Estimation of Dulling Rate and Bit Tooth Wear Using Drilling Parameters and Rock Abrasiveness
Abstract: Optimisation of the drilling operations is becoming increasingly important as it can significantly reduce the oil well development cost. One of the major objectives in oil well drilling is to increase the penetration rate by selecting the optimum drilling bit based on offset wells data, and adjust the drilling factors to keep the bit in good condition during the operation. At the same time it is important to predict the …
