An Investigation Of The Use Of Surface-Active Agents In The Secondary Recovery Of Oil By Water Flooding, Robert P. Schafer

Masters Theses

"The importance of producing oil cannot be emphasized enough in this modem world. Therefore, when primary methods of production seemingly exhaust the oil reservoirs, a secondary method of producing more oil is a necessity. At the present time, secondary methods of oil recovery have developed into a large industry. They are not a new development. The need of introducing compressed air or air-gas mixtures into the wells to increase production was quickly realized. Water flooding methods followed, and at first were restricted to the Eastern fields. Later, about 1935, systematic water flooding methods were developed and applied all over the …

Plastic Deformation Of Rocks, Muhammed Abdul Waheb

Masters Theses

"The purpose of this investigation is to search for a method by which the strength properties of a rock may be described.

For this purpose, an attempt has been made to find out some relationship by which the rooks may be classified or described. For the solution of problems of mine stability, the mechanical properties of a rock should be known, i.e., hardness, toughness and strength. It is difficult to make a study of some method of classification or description of a rock without knowledge of these properties.

With a view to achieve the solution of a general classification for …
