... curve. First, a dynamic permeability model was proposed to describe the filtration rate of the fracturing fluid during hydraulic fracturing. Combined with the point source function, the flowing bottomhole pressure ( p wf ) can be quickly calculated based on the fracture morphology and displacement...

... of penetration (ROP). The results show that the turbine can rotate continuously under hydraulic drive. The turbine torque/velocity and the tool’s pressure drop increase with increasing displacement. The cuttings transport in the annulus is jointly affected by factors such as turbine velocity, fluid velocity...

... in subsea wells with long lead-in lengths. Hence, it would be desirable to acquire the temperature response from LF-DAS data to use as a multipurpose tool for in-well monitoring. Here, we show that when purely investigating the response to an initial displacement of the fluid column (i.e., from rest), LF...

... been studied using a rheometer, and the resulting R -factor, which indicates the degree of compatibility between fluids, has been calculated. An increase in the flow curve was observed for the mixture of the fluids. However, based on the R -index, these fluids are compatible with displacement...

... efficiency increases with the increase of turbine speed, drilling fluid displacement, and viscosity and decreases with the increase of cuttings particle size. Each of these influencing factors has a critical value. When the turbine speed and drilling fluid displacement are higher than the critical values...

..., with displaced fluid becoming easily trapped and leading to poor isolation. Here, we investigated spiral displacement of washout, which is one kind of irregularity, where the spiral flow is induced by a cyclone centralizer. The features of spiral flow with sudden hole enlargement, differences between spiral...

...Lucas Mejia; Yujing Du; Matthew T. Balhoff Summary An efficient tertiary chemical flood involves the chemicals displacing the oil in a stable manner, so the initially disconnected trapped oil ganglia coalesce into a bank as the flood progresses. However, the location of surfactants and polymers...

Our simulations on the capillary rise in dual-wettability tubes are compared with theoretical predictions, which...

They also depend on the history of the displacement ( Killough 1976 ). The pressure dependence of these parameters is important in some...
