... 2, displacement of methane by flue gas (14% CO2 and 86% N2) was conducted under conditions similar to those of Test 1. Figure 4 presents the composition of the produced gas from each of the sand-packs as well as the combined effluent. It indicates that nitrogen concentration in the effluent from...

.... Separation of CO2 and nitrogen from natural gas requires substantial amount of capital and operational expenses. Thus, the objective of our laboratory tests was to identify the key factors that affect the extent of mixing during gas-gas displacement within porous media. Very few research reports relevant...

... with the addition of nitrogen or propane was much better. Significant improvements in design and operation of these processes were needed in order to promote override during the early phase, and obtain a stable and efficient process. The improvements included: a cold (gas fingering) and a hot (steam based...

Drilling with motors can be very effective but motors are susceptible to performance issues especially if high nitrogen ratios are required. Jetting the scale is possible...

... water (dry cores) to confirm and bench mark the results by other investigators. The tests on consolidated cores showed that for pure nitrogen and pure CO 2 , used as the displacing medium, the recovery was comparable. In case a mixture of CO 2 and nitrogen displaced the natural gas, it was observed...

... this, the hydrostatic head of liquid in the hole must be decreased, which can be accomplished by co-injecting nitrogen, natural gas, flue gas, vitiated air (air mixed with nitrogen), or de-oxygenated air (air with some of the oxygen removed). The oxygen containing gases are the least expensive but the possibility...
