Answer 1

A ghost hole is an uncased section of well that cannot be reentered

Question 2

Abandoned Status

Answer 2

For a well that has been drilled and had some other well operation performed (i.e., production, injection, testing) and then subsequently abandoned downhole and at surface.

Question 3

Preset Surface Casing

Answer 3

is always assigned the initial well event sequence

Question 4

1. Closed Status
2. Blowouts
3. Kicks

1. For a well that has been shut in or closed by an AER order resulting in the company not being able to operate the well.
2. A blowout is an unintended flow of wellbore fluids at surface that cannot be controlled by existing wellhead and/or blowout prevention equipment or a flow from one pool to another pool(s) (underground blowout) that cannot be controlled by increasing the fluid density.
3. A kick is any unexpected entry of water, gas, oil, or other formation fluid into a wellbore that is under control and _can be circulated ou_t.

A volume of cement placed in the casing to abandon a well or isolate a completion interval (i.e., abandon a pool)

Question 6

1. Fracture
2. Multistage Fracture
3. Perforation

(gross completion intervals (GCIs))

Answer 6

1. Rocks split by applying pressure to the formation via the wellbore.
2. A system of fracture ports on a liner separated by external casing packers
3. Holes made through the casing and cement into a formation using a perforating gun or pneumatic drill in order to expose the formation. Include intervals in the GROSS COMPLETION INTERVALS (GCI)

Question 7

2. TVD

Answer 7

1. A device used to isolate the annulus from production tubing in the wellbore to allow separate production, injection, or treatment
