29
Q

What are the two primary well stimulation techniques

A

Acidizing and fracturing

30
Q

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

A

– Hydrochloric which is used to dissolve calcium carbonates

– Hydrofluoric which is used to dissolve silica

31
Q

How hydraulic fracture treatment works?

A

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

32
Q

In fracturing what is used to keep the fractures open?

A

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

33
Q

What is hydrostatic pressure?

A

Is the pressure exerted by the column of fluid

34
Q

What is the hydrostatic pressure of water!

A

9.8 kPa per meter of depth

35
Q

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

A

Load fluids

36
Q

The mixing of production in the wellbore is known as?

A

Commingling production

37
Q

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

A

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

38
Q

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

A

A workover

39
Q

What is considered a capital versus an expense workover?

A

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
