In this study, the comparison of dry gas injection for vertical and horizontal production well scenarios are investigated by means conducting a reservoir simulation study tight condensate reservoir. order to conduct pattern has been defined. The selected is 420x420 m in areal extend 50 thickness. All necessary rock properties, fluid specifications together with compositions have determined cons...

Ultrashort-Radius Horizontal Well (URHW) drilling engineering plays an important role in increasing the recovery factor of old oilfields. By sidetracking wellbores at a very high build-up rate, URHW can effectively exploit residual oil near wellbores. Currently, main problem faced is reduced torque received by drill bits owing to increased friction between flexible assembly and wellbore as hori...

This paper presents the viewing angle improvement of integral imaging (II) three-dimensional (3D) display system using horizontal and vertical multi-directional projections and elemental image (EI) rearranging method with pepper and salt noise reduction. Through this way, each elemental lens of micro lens array gathers horizontal and vertical multi-directional illuminations of multiple EI sets ...

This study determines the optimum insulation layer thickness to be applied external building walls considering heating degree-day (HDD) method, then energy saving costs, payback periods, and carbon dioxide (CO2) emissions are calculated accordingly. The optimisation analysis is performed for four different thermal materials (glass wool, rock extruded polystyrene, expanded polystyrene). Natural ...

In this paper, we consider the axial motion of a directional multi-sectional drill-string. The drill-string dynamics are represented by distributed dynamical model (wave equations) coupled with an ordinary differential equation at downhole boundary (bit-rock interaction). interaction between drill-bit and rock can introduce severe vibrations in result safety performance issues. Consequently, dr...

The use of multilateral well is becoming an emerging method to improve oil recovery efficiently and to drain reservoirs more efficacious. By developing drilling technology, completing the oil wells as multilateral wells become more interesting especially from economic point of view. On the other hand, lack of any means for forecasting the performance of this type of wells causes drilling of...
