Leaving the separating tank, the oil and water were directed to their original tanks. The liquid volume flow rate was monitored by a mass flowmeter (CMF100, Micro Motion), whose accuracy was ± 0.1%. Measuring equipment Measurements included water holdup, pressure drop, and flow patterns,...
In the “zipper-fracturing” operation of Pad A, obvious instantaneous shut-in pressure differences were observed in the fracturing operation of each stage in Well 1 and Well 2. The pressure and fracture propagation of three wells were monitored in real time by pressure monitoring and micro-seism...
in the case of ignored wellbore pressure loss,the optimal length of water recovery well is close to the production well,this measure could be more effective to reduced water-cut in different water recovery time;the larger the quantity of water recovery is,the better water control is,and water...
Selection of separators and reserve tanks for UBD involves using a method to predict reservoir fluid inflow rate and volume. Such a method is not available in the literature for UBD horizontal wells. This study filled the gap. In this study, we derived an equation for pressure distribution in...
9.9.3.2.2Thermal relief, thermowells, and pressure taps Heat exchangers should be inspected to determine if thermal relief has been provided for cold-side service to prevent overpressure if cold flow is blocked while hot side flow continues. If none is provided, a piping spool with a relief ...
Method and device for avoiding losses due to filling and release of vapors in the case of volatile substances stored in horizontal cylindrical tanks, through the use of a sheet member. The invention is characterized in that the sheet member is inserted or attached to the tank containing the liq...

Horizontal wells can also be used for remediation purposes....
