The issue of vertical wells curvature is important, especially when conducting wells in complex geological conditions of drilling, due to the increasing depth of the wells and the corresponding rise in the cost of drilling. The cause of this circumstance lies in the large time and financial costs while flattening of the bent wells. Moreover, it should be noted that during the subsequent drilling of a curved well the risk of key-seating and the corresponding complications increases. That is why large oil field service companies and drilling enterprises are paying more and more attention to solving the problem of vertical wells curvature. This article is devoted to investigation the effect of rotation of the drill string on the deflecting force on the bit while drilling a vertical well in a rotary way. We suggest using of eccentric drill collars for drilling vertical wells in difficult geological conditions. Also, we create an expression for the dynamic milling force on the bit, taking into account the usage of an eccentric drill collar in the composition of bottom-hole assembly.

Military Production

Middle East militaries can be arrayed along a continuum from more to less involvement in national economies, albeit with a few outliers. At the maximum engagement end are Egypt and Iran. In both countries, as in Pakistan, one can reasonably refer to the existence of a “Military, Inc.” The Egyptian Ministry of Defense and its subordinate Ministry of Military Production preside over a sprawling economic empire that directly owns companies active in the industrial, agricultural, construction, telecommunications, and service sectors. The Iranian Islamic Revolutionary Guard Corps presides over a similar economic empire that has particularly strong positions in the oil field service, construction, port operation, and media and telecommunications sectors. Both countries also have what might be described as parallel “officer economies.” These have come into existence as a result of officers, many of them retired, capitalizing on their regime connections by gaining ownership of privatized state-owned enterprises or by forming companies that thrive on state contracts. These two military economies are subject neither to the effective oversight of legislative or nonmilitary executive authority nor to the scrutiny of civil society, including the media. Both provide essential patronage resources to ensure the loyalty of their officer corps. And in both countries, military preparedness and overall capacities suffer as a result of preoccupation with the management of and benefits from military economies.

Composite Pipes

AbstractGlass-reinforced epoxy (GRE) pipes are used as an alternative to carbon steel pipes in desert oil field applications owing to their good properties such as chemical resistance, thermal resistance and mechanical properties. In the desert oil field service, the pipes are exposed to different harsh environmental conditions such as high temperature, humidity and ultraviolet radiation. The harsh environmental conditions can affect the properties of GRE pipes, which, in turn, can impact their performance. The present study covers the effects of environment factors such as crude oil and well stream chemicals on the properties of GRE pipes. The pipe samples were aged in wet crude, effluent water and scale inhibitor to simulate the exposure to desert oil field service. The aged samples were evaluated for their mechanical properties, thermal stability and chemical resistance. The compositional change in the composite structures was characterized using Fourier transform infrared spectroscopy and matrix deterioration by scanning electron microscopy. Swelling studies revealed no significant diffusion by the chemical media. Tensile testing showed a slight change in tensile strength with aging in crude oil. In addition, all the pipe samples showed adequate thermal stability to withstand harsh environmental conditions.
