Drilling Rig

• Is a machine which is used for creating a hole in ground.

There are many factors to be considered in selecting the best rig for the job, a few are especially critical. They are:

– Surface location (land, inland water, offshore).– Estimated maximum hole depth.– Horsepower requirements.– Cost.– Availability.

Land Rigs

As the name implies, these rigs are primarily used on land.

Offshore rigs

Offshore rigs

Inland Barges are composed of two types:

a. Barge mounted rigsThis type rig is capable of drilling in water depths from 0 to 12 feet. After being towed on location, the rig’s hull is filled with water until it rests on bottom

b.Posted barge mounted rigsPosted barges are capable of drilling in water depths from 0 to 20 feet

Offshore rigs

Submersible Rigs :These rigs and are capable of working in water depths from 18 to 70 feet or (90-1000)m.

Offshore rigs

Offshore rigs

Fixed jacket:Depth:Shallow…500m or less.

Offshore rigs

Drill Ship:Depth:deep…2500m or graeter than.
