Preslug

A preslug of brine solution is often used to condition the reservoir by displacing the reservoir brine.

Usually preslugs were injected to realize optimum salinity in the reservoir and also to control cation exchange.

In the first preslug, the foaming concentration was 1.5% and the polymer was 1800ppm.

Los Alamos concluded that the use of preslugged material is beneficial, 10 tsi is the optimum pressing pressure, and binders are not necessary.

One structure consists mainly of spherical porosity; the other consists largely of nonspherical interconnected porosity surrounding high density regions, typical of the material produced by the high pressure preslugging process.

Pellets will be preslugged and granulated, binder will be added as needed and the powder will be fed to a high speed pellet press and apparatus to check density, load the pellets into boats and transfer them to the loading and sintering operation.

Either header sheets or dark-mark coding directly on the answer document itself provides the input to the computer memory for pre-codable information such as test, level, or form, while response spaces to be marked by the user take care of all kinds of unique identifying information, such as community, school, grade, name, sex, and so forth. Preslugging on a line printer is used for a student identification code.

The reaction to the computer-prepared preslugged answer sheets was unanimously favorable. The preprinting of the applicant's identification number and name on a tear-off end strip made positive identification quick and easy.
