Programming general overview

To understand the approach taken in developing the QA program at DCLS, it is necessary to have a general overview of the organizational structure of the laboratory, and of the program itself. 

As far as the temperature program is concerned, reasonable results have been achieved using T = Tof (n = 0...nmax), with m MC-steps between temperature updates. Here, To, f, nmax and m should be chosen according to the size of the system, the moveclass and the objective of the current optimisation run. The latter refers to the fact that different strategies have to be chosen, if one wants to find as deep a minimum as possible for a given amount of computer time or whether one tries to gain a general overview over the statistical distribution of local minima and their accessibility 16. ... 

The LHASA program is exceedingly complex - about 400 subroutines, 30,000 lines of FORTRAN code and a data base of over 600 common chemical reactions. To describe it in detail is well beyond the scope of this paper. A general overview is relevant as it puts the functions of the data base in a reasonable perspective. Figure 1 shows a global view of LHASA. 

The objective of this paper is to present Conoco s current methodology for the systematic evaluation of different gel systems for permeability modification. First, the beaker and core test techniques used in the evaluation of gel systems are reviewed. Then, the experimental approach followed for a complete gel evaluation is discussed. Laboratory results are included in this discussion to Illustrate the Importance of the various steps in the evaluation process. In addition to the general overview of our testing program, results are presented that demonstrate the usefulness of the beaker tests in identifying trends observed in core tests. 

For the environmental consultant, an extensive overview of corrective action technologies is provided. Topics covered are the general concepts of corrective action programs, facility investigation principles, treatment technologies for wastes and waste streams, post treatment technologies and engineering considerations for corrective measures implementation.
