... lithology, drivemechanisms and oil density. Productivity Improvement Factors (PIF, the ratio of production of a horizontalwell to a vertical well for the first 12 months) and the key benefit(incremental oil recovery versus acceleration) of horizontal wells were alsoexamined. Overall, the horizontal wells...

Results obtained demonstrate that the systems without stinger installed yielded a sharper water cone profile, earlier water breakthrough, and a significantly lower oil recovery than those with stinger did. Installing a stinger flattened the water...

Abstract This paper set up a mathematical model of three-dimensional transient flow to describe the pressure behavior for horizontal well with wellbore storage and skin effect in naturally fractured infinite and box-shape-bounded reservoirs. On the basis of obtaining solutions of mathematical...

... the process of air injection involved a producer well arrangement, such that the combustion front propagation and hence displacement of oil occurred in a toe-to-heel manner. This is called the ‘Toe-to-Heel’ - Horizontal Wells Process (THHW). Five experiments were conducted, using two base homogeneous...

... Abstract A 3-D physical model has been developed to investigate the Combustion Override Split-Production Horizontal well (COSH) process. The 3-D model was rectangularbox with I8 cm by 54 cm by I2 cm dimensions. The vertical well was used as anair injection well and top horizontal well was used...
