Even with the fractured wells, primary oil recovery of low-permeability reservoirs is still poor in Block X Shengli Oilfield. To further enhance recovery, water injected into reservoir. Different from conventional injection scheme, maximum daily rate proposed scheme by Oilfield reaches 2000 m3, and average around 1500 m3. Thus, well spacing certain pattern not suitable for novel scheme. In pape...

in this research, the appropriateness of drainmod-n model was evaluated for the simulation of nitrate transport with subsurface drainage in paddy fields. during a canola growing season from november 2011 to april 2012, the nitrate concentration of drainage water and soil saturation extracts of two depths of 30 and 60 cm was measured in consolidated paddy fields of sari agricultural sciences and...

BACKGROUND A woman's health seeking behaviour during pregnancy has been found to have significant repercussions on her wellbeing and that of her unborn child. For example, the risk of poor pregnancy outcomes and maternal death is higher among women who do not receive antenatal care. METHODS The study described the characteristics of women who reported wanted, unwanted and mistimed pregnancies...

The vapor extraction (VAPEX) process, a solvent-based enhanced oil recovery process has been found promising for some heavy oil reservoirs. In this work, the VAPEX process is studied using a compositional simulator on a number of single-block and multiple block fractured systems. PVT data of one of an Iranian heavy oil reservoir are used to tune the equation of state. Effects of fracture sp...
