Determination of formation damage in limestone reservoirs and its effect on production
Bagci, S.; Kök, Mustafa Verşan; Turksoy, U. (2000-10-01)
Reduction of injectivity of wells by formation damage can be of considerable magnitude during waterflooding of oil reservoirs. Variation of pH of the flowing fluid is an indicator of chemical activity occurring in the formation. High pH promotes formation damage by particle deposition within the porous media and consequently particle bridging at the pore throats. Permeability reduction is used as quantitative measure of formation damage. In this paper, the results of core flow experiments in limestone forma...
Determination of fracture and fatigue behaviours of 4340 steel
Şen, Gökçe; Gürbüz, Rıza; Ögel, Bilgehan; Department of Metallurgical and Materials Engineering (2015)
In this study both the characteristic and mechanical properties of received modified AISI 4340 steel -generally used in aeronautical and defense applications- has been examined. Mode I Fracture toughness (KIC) tests have been conducted with two different directional specimens of RL and LR. Fatigue crack growth behaviors of directional specimens are compared and discussed at three different positive stress ratios (R) which are 0.1, 0.3 and 0.5 under constant amplitude loading. Walker equation is used to perf...
Determination of hot crack susceptibility in various kinds of steels
Ankara, Alpay; Ari, Haldun Bülent (1996-01-01)
The aim of this investigation was to study the hot crack susceptibility of some Turkish and German structural steel plates with a modified varestraint-transvarestraint test method. Testing was accomplished using a Tungsten Inert Gas (TIG) welding process. The results of this study revealed that total crack length increases as welding current increases or punch radius or welding speed decreases. An attempt is made to provide explanations for these phenomena. (C) 1997 Elsevier Science Ltd.
