Question 29

What are the two primary well stimulation techniques

Answer 29

Acidizing and fracturing

Question 30

What are the two principal types of acid used in a well acidizing stimulation treatment

Answer 30

– Hydrochloric which is used to dissolve calcium carbonates | – Hydrofluoric which is used to dissolve silica

Question 31

How hydraulic fracture treatment works?

Answer 31

Fluids are pumped into the well at high rates and high-pressure that creates fractures information

Question 32

In fracturing what is used to keep the fractures open?

Answer 32

A proppant, which usually is a specially selected sand carry into the frak in a viscous fluid called a gel

Question 33

What is hydrostatic pressure?

Answer 33

Is the pressure exerted by the column of fluid

Question 34

What is the hydrostatic pressure of water!

Answer 34

9.8 kPa per meter of depth

Question 35

The fluids used during a completion or workover for killing the well, as frac fluid are known as

Answer 35

Load fluids

Commingling production

Question 37

Before production may be commingled, approval must be granted by the Alberta energy regulator under which restrictions?

Answer 37

– Pressure in the zone must be comparable – Fluid in the zone must be compatible – The rights of all parties must be conserved

Question 38

Any work on the wellbore which changes the flowing characteristics of the well or repairs a problem within the wellbore can be classified as

Answer 38

A workover

Question 39

What is considered a capital versus an expense workover?

Answer 39

Generally the cost of the initial completion of a productive zone will be capitalize and any other subsequent work on the well will be considered as an expense work
