Knowledge Check

1. What is the purpose of gas lift?

To inject water into the reservoir To reduce the hydrostatic head in the tubing so reservoir pressure can push more oil to surface To fracture the formation To measure downhole pressure

2. What happens when you inject gas beyond the optimal gas lift rate?

Production doubles Production gains diminish and excessive friction can actually reduce output The well shuts in automatically Water cut drops to zero

3. Why might an engineer choke back a well?

To increase production rate To prevent sand production, water coning, or protect downstream equipment To increase reservoir pressure To measure gas-oil ratio

4. What does a Voidage Replacement Ratio (VRR) of 1.0 mean?

Production equals injection at surface conditions Every barrel of fluid withdrawn is replaced by injection at reservoir conditions The field has reached abandonment Water cut is 100%

5. In nodal analysis, what determines the well operating point?

The maximum pump rate The intersection of the IPR and VLP curves The choke size alone The separator pressure alone

6. What is a Capacitance-Resistance Model (CRM) used for?

Designing surface facilities Quantifying injector-producer connectivity using rate and pressure data Measuring tubing corrosion Calculating drilling costs
