Well control technique is particularly important in oil and gas operations such as drilling, well work over, and well completions because of higher drilling costs, waste of natural resources, and the possible loss of lives of rig personnel. It is known very well that the larger the volume of influx, the more difficult to bring the well under control. The aim of this study is to lessen volume of influx from the formation by shut-in the well with a new well control approach. This approach is based on decreasing the difference between the formation pressure and the bottom-hole pressure by pumping drilling mud after shut-in. A multiphase dynamic well control simulator has been used to demonstrate results of study. It was observed that when this new approach was applied, the volume of formation fluid invasion and stabilization time decrease.

The Use of capacitance-resistive models for estimation of interwell connectivity & heterogeneity in a waterflooded reservoir: a case study Gözel, Mustafa Erkin; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2015) Increasing the oil recovery from the hydrocarbon reservoirs is becoming the most important issue for the oil & gas industry with the increase in energy demand and developing technologies. Waterflooding is one of the most preferable methods because of its success ratio, application ease and cost efficiency. Beside mentioned advantages, this method must be carefully planned and performed by considering reservoir heterogeneities to avoid unexpected poor recoveries. As an alternative to the reservoir modeling a...
An Experimental study on the effects of different chloride sources on the properties of API Class G cement Ramazanoğlu, Özge; Yaman, İsmail Özgür; Akın, Serhat; Department of Cement Engineering (2014) In the petroleum industry, oil well cements are used in the form of slurries during the construction of oil or natural gas wells. Preserving the integrity of the well and the casing, providing zonal isolation are some of the uses of these special cements. Oil well cement slurries used in the petroleum industry are subjected to different exposure conditions than ordinary Portland cement slurries used in the construction industry. Therefore, oil well cements are required to possess different engineering prope...
An Experimental investigation of the shale inhibition properties of a quaternary amine compound Taş, Baki Tuğrul; Sınayuç, Çağlar; Gücüyener, İsmail Hakkı; Department of Petroleum and Natural Gas Engineering (2013) Depleting oil reserves and increased costs of the oil and gas recoveries have created the need to drill in challenging formations. When drilled through, shale formations in particular always generated a wide variety of problems if conventional water-based muds are used. Furthermore, the complexity and variations in shales have compounded the task of developing suitable drilling fluids. In light of these problems, the study of shale properties and their interactions with fluids will continue to be a muchneed...
Evaluation of limestone incorporated cement compositions for cementing gas hydrate zones in deepwater environments Hıdıroğlu, İnanç Alptuğ; Parlaktuna, Mahmut; Yaman, İsmail Özgür; Department of Petroleum and Natural Gas Engineering (2017) One of the potential problems which must be overcome during oil or gas exploration in deepwater environments is to complete the drilling operations without decomposing the gas hydrates. Gas hydrates remain stable as long as the thermodynamic conditions are not changed. But, especially by increasing temperature during drilling operations, there is always a possibility of change in thermodynamic conditions, which will cause decomposition. Another factor which may disturb the thermodynamic conditions is the ev...
A Comparative study of cuttings transport performance of water versus polymer-based fluids in horizontal well drilling Allahvirdizadeh, Payam; Parlaktuna, Mahmut; Kuru, Ergun; Department of Petroleum and Natural Gas Engineering (2015) High drilling fluid circulation rate is often needed for effective transportation of cuttings in horizontal and extended reach wells, which may not be always achievable due to the risk of fracturing the rock by increased bottom hole dynamic pressure and also limit of pumps capacity. Keeping the bottom hole pressure low enough while increasing the flow rate is, therefore, a major challenge in horizontal well drilling operations. A potential solution to this problem would be to use drag reducing additives in ...
