| Description |
This is a Joint
Industry Project (JIP). This is the second phase of a project that was completed in 1994;
this project will build on the results of the first phase. The first project identified
several issues with Blast Furnace Slag (BFS) in muds. Phase II will focus on other
applications of BFS/Mud systems, BFS-Cement, or BFS by itself in comparison to Portland
cement studies. The first part of Phase II will be a literature search on the hydration of
BFS. The second part of Phase II will be gas leakage tests simulating geo-pressured
reservoirs with various slurry compositions. The third part of Phase II will measure the
plastic state shrinkage simultaneously with total hydration volume reductions under
different pressure conditions for all the systems in question. Part four will test the
ability of various systems to seal gas in an annular configuration over long times with
applied high stress. Part 5 involves testing the systems for kickoff plug applications. |
| Progress |
Complete. BFS can be
as effective as Portland cements when properly designed. In addition, the gas migration
model design and test procedures evolved into a system that produces sensitive, reliable,
and accurate comparative gas migration results. The annular seal test device provided a
reliable way to test the long term seal of various cement systems under high stress
conditions. |
