Roc Oil Company Limited (ROC) has started drilling the second of two planned exploration wells, QK12-3-1D, in Block 09/05 in the Bohai Bay Basin, China.
According to AWE Limited, a partner in the project, the well will be drilled to a planned total depth of 3,600m MDRT (Measured Depth below Rotary Table) and drilling operations are estimated to take 26 days to complete.
The QK12-3-1D well has been designed to test the oil potential of a 3-way dip closed structure matured by 3D seismic data. QK12-3-1D has two primary stacked objectives (Miocene age Guantao reservoirs and Pliocene age Minghuazhen reservoirs), and a secondary objective (Oligocene age Dongying reservoir).
Block 09/05 is located in the western part of the prolific Bohai Bay Basin in China, approximately 10km southeast of Tanggu, the largest port in China. The block covers an area of 335 km2 with water depths from approximately 5m to 10m.
The block has the benefit of low drill and development costs, proximity to existing infra-structure and attractive fiscal terms, AWE said.
The joint venture partners in Block 09/05 are AWE Limited with 40% interest and Roc Oil, operator, with 60% interest.
