Identification of cavities in Kepulauan Tanimbar
Our team has just completed our project in the Kepulauan Tanimbar. The objective of this project was to identify cavities for potential drilling, which can later serve as a guide for future construction. Below are some key conclusions from our microgravity survey:
The identification of voids/cavities during the initial drilling was based solely on the visual observation of the drill string’s faster downward movement, without any additional verification method.
Diagraphy drilling continuously records five (5) parameters during the drilling process. The results indicate no voids or cavities up to a depth of 30 meters at several locations.
The microgravity data was processed using a 3D modeling technique, incorporating the recorded diagraphy drilling parameters as calibration values.
The microgravity surveys conducted in the test area were validated by data from the diagraphy drilling.
The microgravity survey in the main area is expected to yield reliable data for detecting potential cavities.
