The industry of drilling for oil, gas geothermal, and storage purposes necessitates construction of challenging wells in recent applications. Challenging wells are required to be designed prior to the drilling to selection of the equipment to be utilised while drilling. A poor engineering planning may result in losing time and effort to remediate torque and drag related troubles which might be encountered. Adequate planning is significantly important which is going to reveal possible drawbacks in planned well prior to commencing operations. The drag and torque calculations are required to be estimated and monitored accordingly whilst drilling of the wells. This paper gives the details of torque and drag calculations for every one-metre interval, so that the rig crew can see what is the theoretical calculated magnitudes and compare them to the actual. Implementation of this study is going to identify limitations due to torque and drag allowing safe drilling.

Trajectory estimation in directional drilling using bottom hole assembly(bha) analysis Doğay, Serkan; Kök, Mustafa Verşan; Department of Petroleum and Natural Gas Engineering (2007) The aim of this study is to combine the basic concepts of mechanics on drill string which are related to directional drilling, thus finding a less complicated and more economical way for drilling directional wells. Slick BHA, which has no stabilizers attached and single stabilizer BHA are analyzed through previously derived formulas gathered from the literature that are rearranged for this study. An actual directional well is redrilled theoretically with a slick BHA and a computer program is assembled for c...
Drilling of gas hydrate reservoirs Merey, Sukru (2016-09-01) With the consumption of conventional hydrocarbon reserves and advancement in drilling technology, recently there is a high interest in gas hydrates in the world. Due to lack of experience and sensitive nature of gas hydrates, drilling in gas hydrate reservoirs were considered as risky. However, recent drilling data in gas hydrates shows that successful drilling operations in gas hydrate reservoirs are possible with some special measurements such as specially designed drilling fluid and cement slurry etc. In...
Analysis of finite element method solution of sinusoidal buckling behaviour of drill string in vertical, directional, and horizontal wellbores and comparison with analytical solutions Cebeci, Mehmet; Kök, Mustafa Verşan; Gücüyener, İ. Hakkı; Department of Petroleum and Natural Gas Engineering (2017) The buckling of drill string in oil, gas and geothermal wells is a critical problem that has been of interest to many researchers in the industry. Prevention of buckling of drill string is important since it may negatively affect the drilling operations. When buckling of drill string occurs, it may cause deviation control problems while drilling, inefficient load transfer to the bit, excessive torque values, even pipe failures due to fatigue. The first rigorous treatment of stability of drill strings for ve...
Torque and drag applications for deviated and horizontal wells: a case study Çağlayan, Burak Kağan; Kök, Mustafa Verşan; Eren, Tuna; Department of Petroleum and Natural Gas Engineering (2014) One of the most critical limitations during hydrocarbon exploration, especially during directional drilling, is torque and drag generated by the contacts between the drill string and the borehole or casing. Therefore, torque and drag analysis and calculations are very important for well design to prevent equipment and economical losses. Proper modeling is highly important to predict and prevent downhole problems related to drill string and borehole, beforehand commencing to the activities if not during the ...
Investigating the relationship between unsafe acts and organizational safety climate in drilling industry Aydınlı, Hakan Oktay; Öz, Bahar; Department of Occupational Health and Safety (2019) Drilling for oil, gas, and geothermal both onshore and offshore is classified in a very hazardous job category. Thus, drilling site employees are expected to maintain high levels of job safety awareness. The aim of the current study is to investigate the relationship between unsafe acts and organizational safety climate in drilling industry. In the light of Reason’s human error taxonomy, Unsafe Act Questionnaire (USAQ) was developed. USAQ and Integrated Safety Climate Scale (ISCQ) were applied to drilling s...
