The casings include: drive pipe, aquifer casing, coal protection casing, intermediate casing, and production casing.
The ID and OD of the coal protection casing, intermediate casing, aquifer casing, and drive pipe are listed.
The five string casing system will include the drive pipe, aquifer casing, coal protection casing, intermediate casing, and production casing.
There is one resin-based carbon fiber drive pipe one each end of the tensile lock which prevent involvement during deploying process.
After the initial setting and data entry, the model automatically selects proper casing size and grade for the aquifer casing, coal protection casing, intermediate casing, and drive pipe.
The user will provide the input parameters including depth of the coal seam and the fresh groundwater and the model will generate the results including a schematic view of the casings, the outside and inside diameter of the aquifer casing, the grade and type of aquifer casing, coal protection casing, and drive pipe.

A numerical investigation is carried out to study the mixing by chaotic advection in an electromagnetically driven pipe mixer.
For the suction driven pipe flow with the expanding wall (e.g. α= 2), we find a new solution numerically and classify it as a type VI solution.
In this study, the particle diffusive model proposed by Phillips et al. (1992), combined with general flow equations, was extended to solve the flow of concrete and predict the particle concentration distribution of suspensions in a pressure driven pipe flow.
