... permeabilities. Lower efficiencies have generally been compensated for by increased volume and/or injection rate. Treatment Volume In order to achieve optimum fracture area and satisfactory productivity in low permeability formations, volume requirements have increased tremendously. Long intervals and large well...

... by application of electrical energy. Formation of an electrically carbonized zone of 10 darcies permeability, high oil recovery, moderate thermal-productive requirements, and the production of qualitatively important proportions of elec~rocarbonization gas have been demonstrated with linear laboratory tar sand...

... of any magnitude is undertaken, it should first be determined just how record keeping and data handling fit into the overall organization of the production department and how it is linked with other departments of the company. Many of the requirements for production and engineering information from...
