Directional and horizontal drilling operations are increasingly conducted in all over the world, especially parallel to the growth of the technological developments in the industry. Common application fields for directional and horizontal drilling are in offshore and onshore when there is no way of drilling vertical wells. During directional and horizontal well drilling, many additional challenges occur when compared with vertical well drilling, such as limited weight on bit, harder hole cleaning, trajectory control, etc. This makes even harder to select the proper drilling parameters for increasing the rate of penetration. This study aims to propose a rate of penetration model considering many drilling parameters and conditions. The proposed model is a modified Bourgoyne & Young’s model which considers formation compaction, formation pressure, equivalent circulating density, and effective weight on bit, rotation of the bit, bit wear, hole cleaning, inclination, fluid loss properties and bit hydraulics. Also, a bit wear model is developed for roller cones and PDCs. The model performance is tested using field data obtained from several directional and horizontal offshore wells drilled at Persian Gulf. It is observed that the model can estimate rate of penetration with an error of ±25 % when compared with the field data.

A study on the application of e-commerce in Turkish mining industry
Mutlu, Yakıcı İçli; Güyagüler, Tevfik; Department of Mining Engineering (2005)
In this thesis, a road map/strategy that must be followed by firms that want to utilize e-commerce facilities is established. For this purpose, road map suggestions that were taken from literature were examined and a road map which can be followed by mining companies is developed. First, a questionnaire was applied to mining firms to understand the attitude of mining sector to e-commerce. Then a firm that had involved in the questionnaire and was interested in e-commerce was selected to work with. The studi...
A methodology for detection and evaluation of lineaments from satellite imagery
Koçal, Arman; Karpuz, Celal; Department of Mining Engineering (2004)
The discontinuities play an important role both in design and development stages of many geotechnical engineering projects. Because of that considerable time and capital should be spent to determine discontinuity sets by conventional methods. This thesis present the results of the studies associated with the application of the Remote Sensing (RS) and the development of a methodology in accurately and automatically detecting the discontinuity sets. For detection of the discontinuities, automatic lineament an...
A new concept on sampling systems by air cannon application
Yünel, Ufuk; Hiçyılmaz, Cahit; Department of Mining Engineering (2004)
The most important criterion in industrial production processes is to control the required product quality and comply with the standards pre-described for the application during any stage of the process. This control begins from the entry of raw material to the plant and continues with pre-determined points. Mainly two different types of inspection and analyses are used to examine the material quality and content. These are physical and chemical analysis.In most of the production plants above mentioned anal...
Flocculation behavior of two different clay samples from Kırka tincal deposit
Çırak, Mustafa; Hoşten, Çetin; Department of Mining Engineering (2010)
Kırka Boron Plant in EskiĢehir region has been producing tincal contentrate and boron products since 1972. Depending on the industrial demand for boron products, the plant capacity has been gradually enlarged by reaching over 1.5 million metric tons per year. This increase in the capacity has caused serious tailings disposal problems. In addition to the great amount of the tailings (400.000 ton solid waste per year), the tailing material contains mostly clay minerals that show colloidal character. Their sus...
Life cycle assessment of off-highway trucks and belt conveyors for sustainable mining
Erkayaoğlu, Mustafa; Demirel, Nuray; Department of Mining Engineering (2011)
In recent years increasing growth rate of all industrial fields generated an emerging energy demand and consequent environmental problems worldwide. Defining environmental profiles of products and systems using environmental tools, such as Life Cycle Assessment (LCA), is a critical issue for sustainable mining. In order to tackle the increasing environmental challenges and air emissions induced by surface coal mining, alternative material handling options are needed to be evaluated. This research study aims...
