Question

An oil reservoir was originally undersaturated and was known to have no water influx. The field is to be waterflooded and part of the preflood strategy is to determine the new bubble point for this state of depletion. The initial reservoir pressure is 3,000 psia(20,684 kpa) with an initial oil saturation; s oi

Answer 1

Answer:

A petroleum engineer might typically tackle problems such as the following: “Critical rotary speed longitudinally (rpm*) is calculated by rpm* = 258,000/L,. where L is the total length of the drill string (ft).

⏩⏩ A pressure buildup test is run on a well producing dry gas. ⏪⏪ ...

.Current average reservoir pressure is about ..........3,012 psia (20.77 × 103 KPa) and the flowing bottomhole pressure at the time of shut-in was.......... 1,126 psia (7.76 × 103 KPa).

,'''An oil reservoir was originally undersaturated and was known to have no water influx. The field is to be waterflooded and part of the preflood strategy is to determine the new bubble point for this state of depletion. ,,, .......The initial reservoir pressure is 3,000 psia (20,684 KPa) with an initial oil saturation; Soi = 0.90. The abandonment pressure is 1,200 psia (8,274 KPa). At the abandonment pressure the oil formation volume factor is 1.20. ..... .

.

Cumulative oil production to the bubble point is 250,000 stb (39,750 m3 ). Using the above production information and saturations, assume Bob = 1.460 rb/stb (res m3 /m3 )
