Most of Myanmar considered prospective for hydrocarbons was covered by gravity surveys between 1964 and 1975. The results have been published as small-scale contour maps, but with gravity values referred to an arbitrary datum; there are also significant errors and ambiguities in the contouring. An approximate transfer to the current international IGSN71 system has proved possible, but correction of the contouring errors will not be possible without access to the underlying data.
