Study of potential gas eruption by seismic survey in Lake Kivu
2011
SEG Technical Program Expanded Abstracts 2011
unpublished
We have investigated potential risk of gas eruption by air gun operation in a seismic survey on the Lake Kivu, East Africa, which contains a huge amount of gas dissolved in the water zone below a depth of 260 m. Measured data suggest that gas nucleation and bubble growth in a large body of water require super-saturated condition (pressure significantly lower than the bubble pressure (B. P.) and significant long relaxation time (> 1 second). Initial homogeneous gas nucleation in water enhances
