Abstract
The M field is a deep-water field in Sabah, Malaysia, in early stages of production. The field, composed of multiple turbidite reservoirs, is considered structurally complex heavily faulted and compartmentalised, and underlie a rugose sea bottom and complex overburden with presence of gas. After the first development phase, the velocity model was assessed against data acquired during drilling, e.g. well logs and other well-based information. Vertical incidence VSPs acquired in deviated and S-shaped wells indicated that the lateral velocity variations within the overburden is larger than previously modelled, due to a complex overburden. Further refinement of the velocity model is essential for further development planning, reservoir management, and updates to resource estimation.
