Spider Diagram for Tubular Expansion with Restraints

Franz Marketz, Saif A. Al-Hiddabi · المجلة العُمانية للبحوث الهندسية · 2013 · 10.24200/tjer.vol10iss1pp1-10

The aim of this study is to explain the mechanics of tubular expansion in irregularly shaped boreholes such as those frequently observed in the upper Natih reservoirs. Statistical analysis of borehole data does not indicate a strong correlation between the non-circularity and expanded tubular’s in such boreholes. A two …

Dynamic Analysis and Vibration of Beam Inside Annulus for Ultra Short-Radius Water Jet Drilling

Tasneem Pervez, Saif A. Al-Hiddabi, Amer S. Al-Yahmadi وآخرون · المجلة العُمانية للبحوث الهندسية · 2012 · 10.24200/tjer.vol9iss1pp55-63

Conventional water-jet nozzle systems have been developed and partially used in the oil and gas industry to drill horizontal sidetracks. However, this technique still presents a few shortcomings associated with tube buckling and water jet sagging. Due to these problems, the drilled hole deviates from the desired path a …
