EXERCISE 2 Find the definitions to the key words, using the information after the text and translate them into Russian.

The definitions:

A)a piece of equipment used to prevent the rotary motion of the kelly (or drill string) from being transferred to the drilling line.

B)a device that is attached to the bails of the traveling block and used to gripjoints.

C)a device that has several independently mounted sheaves or pulleys and used to lift and lower elevators.

D)the part of the drive assembly which transmits motion to the kelly and permits the kelly to move vertically while it is rotating or still.

E)a shallow cased hole close to the rotary table. When making up a string, each single is stood here so that it can be connected quickly and easily to the kelly.

F)a piece of equipment designed to mix and prepare drilling mud.

G)a wire rope made up of a number of strands wound around a steel core, used to lift or lower drill pipe.

H)a double or a triple, two or three joints connected together.

I)a piece of equipment used to transfer rotary motion through a master bushing to the kelly, to drillpipe and, eventually, to the drill bit.

J)a device on the top of the derrick that provides means of taking drill line from the hoisting drum to the travelling block.

K)a structure above the well used for drilling string tripping, location of stands and protection of drilling crew against wind and precipitation.

EXERCISE 3 Are the following statements true or false? Correct the false ones with the right information and discuss your answers with a partner.

1. Drilling crew members use scratchers to scratch each other and thus clean themselves of oil.

2. Conductor is a person who knows everything at the drilling site. He is in charge of coordinating work of drilling crews.

3. Elevator is a device for lifting derrickman to the monkey board.

4. Doghouse is a room where security guard and patrol dog live.

5. Drilling cuttings are washed out to the surface with drilling mud made of clay and water.

6. Drill pipe is hollow. The reason for this is to make it possible for the mud to pass through it.

7. Cement job is performed only when quality of casing is poor.

8. Cuttings in a well mean cracks on wellbore walls.

9. The kelly is hexagonal. The reason for that is to make it possible for the rotary table to turn the kelly without slipping.

10. Shale shaker is used for separating fluid from drilling cuttings.
