Abstract:

Gas, dissolved in the deep water of Lake Kivu, is geochemically similar to gases derived from the oil and gas fields situated in the Green tuff region. The water of Lake Kivu at about 400 m (1,310 ft) in depth contains 22 millimoles of methane and 77 millimoles of carbon dioxide per kilogram. Therefore, the water may emit gas of about 2.02 cu m (FOOTNOTE 1)/kl at the lake surface. Thus, Lake Kivu gas may be recoverable by means of self-flowing through long pipes. Abiogenic gas resources are expected in some east African rift lakes, caldera lakes, and in some volcaniclastic rocks attributed to large-scale magmatic activities.

FOOTNOTE 1. In this paper, cu m of gas are expressed in Normal cu m, or Nm3, i.e. cu m at 0° C and 1 atm.
