The forces which operate in productive formations and oil
and gas accumulation drives. Oil-, gas- and gas condensate
recovery factor, its general characteristics and the methods of its
increasing.
Environment protection during wells drilling, productive
formations exposing, their completion and testing, and during well
remedial work and well work over.
Peculiarities of environment protection during the gathering
and treatment of well production and during the usage of methods
for increasing oil-, gas- and gas condensate recovery [1, 2, 3, 4, 5,
6, 7, 8, 9, 10, 11, 12, 13, 14, 15].

Control questions

the well affect its production rate?
3. Name and characterize the requirements for chemical
agents used in the processes of oil and gas production.
4. Reasons for deterioration of the state of bottom-hole
formation zone during drilling.
5. Reasons for deterioration of the state of bottom-hole
formation zone during the operation of wells.
6. Organization of reception, storage, delivery and control of
the quality of materials and chemical reagents.
7. Control of water encroachment of wells. Foaming agents
for removing water from bottoms of gas wells.
8. Name and explain the forces that hold hydrocarbons in the
productive formations.
9. Name and explain the forces that help hydrocarbons to
flow through productive formations.
10. Protection of depths and environment during repair and
isolation works in wells.
