OSG measured total and spectral gamma ray (GR & SGR) inside the drill string in Lake Malawi. Due to the recognizable very high risk of losing a sonde when re-entering the drill bit, we decided not to run sondes into the open borehole section. Water depth was 601 m.
This is the only OSG logging campaign at LMDP.
