8. Q

9. Q

10. Q

11. Q

12. Q

13. list two functions of a packer:

Prevent downhole movement of the tubing string

Support some of the weight of the tubing

14. list two factors that affect a completion design

Packers ,Elastomers, Flow control equipment

15. what is the function of perforation

16. with respect to stimulation briefly describe the process of

acidizing

acidizing is performed below the reservoir fracture pressure in an effort to

restore the natural permeability of the reservoir rock

17. list two limitations and advantages of openhole completions

Adv- lower intial cost, max reservoir exposure

Dis- minimal inflow and outflow control, more difficuilt stimulations

18. Apart from hydraulic fracturing list two other types of fracturing

techniques used in stimulation of a well

matrix acidizing and fracture acidizing.

19. Remedial work to primary cementing job is called.

20. Given that a reservoir exists above the bubble point pressure for

the

21. hydrocarbon and also only water and hydrocarbon is

present.give an equation that will represent fluid saturation in the

reservoir

22. list two factors that can affect the values of porosity

Rate of Burial and Depth of Burial

23. How does overburden pressure affect the value of k?

Overburden pressure can reduce the value of k

24. What is effective porosity

Refers to the fraction of that volume in which fluid flow is effectively taking

place

25. Which of the following is relative permeability?

Relative permeability is defined as the ratio of the efffective permeability of a

fluid at a given value of saturation to the effective permeability of that fluid at

100% saturation

26. what is connate water saturation and what are the properties of

water that cause it to wet/adhere to the surface of the rock?

27. what information can be attained from the relative permeability

curve?

Rwo,Rto, Water satuation.

28. Q

29. Given that a rock has a volume of 1000cm3 and its porosity value

is 20% Calculate the space of this rock in m3. .2m

30. define a wet gas making reference to the stock tank conditions

A wet gas has a GOR

36. Reserves are calculated based on degrees of uncertainty What are

the two sets of data: Geological data,engineering data

37. Define the term bg (gas formation volume factor

The volume of gas at reservoir conditions of oil at stp

38. Define the term non-renewable resources

Resources in which the rate of use is faster than rate of formation

39. When would enhanced oil recovery be applied to a reservoir

Employed when reservoir pressures are not sufficient to bring

hydrocarbons to surface

40. What are two types of thermal recovery methods employed

Fire flooding,steam flooding

41. What is the location of where the first contracted agreement for

susbsurface hydrocarbon in the us -

Titusville

42. What was the name of the person contracted -Colonel Edwin

Drake

43. In your own words define the petroleum industry

44. Q

45. Q

46. Specific gravity is given by the formula API = 141.5/131.5 1

True or false (true) learn formula

47. What are the two pathways to the maturation of hydrocarbons :

diagenesis,kerogen

48. List the three basic requirements for the formation of a reservoir:

source rock, reservoir rock, trap rock or seal rock

49. List four pieces of evidence to support why geology is important

to the petroleum industry:

50.

FILL IN THE GAPS:

1. Why is it better to produce from a reservoir that has water wet rock

than one that has oil wet rock.

Because oil won't adhere to rocks with results in more oil within the

reservoir.

2. What is liquid loading?

Once Flowrate drops below a certain rate, the well will begin to load up The

amount of liquid produced does influence how quickly the subsequent loading up

process takes

3. Briefly describe method of acidizing

acidizing is achieved by pumping acid into the well to dissolve limestone, dolomite and calcite

cement between the sediment grains of the reservoir rocks

4. What are two problems that affect drilling a well-Multiple choice 4

choices

5. What is the drilling fluid in wells normally called

Drilling Mud

6. Give two functions of cementing

Restrict fluid movement between formations & Bond and Support casing

7. What are two things that can be done to optimize drilling:Rate of

penetration,Type of bit,Weight on bit,Rotating speed

8. Explain what is a work over

refers to any kind of oil well intervention involving invasive techniques,

such as wireline, coiled tubing or snubbing

9. How does the drilling company get the contract
