The Wenchang oil field is located in the western Pearl River Mouth Basin, about 400 kilometres southwest of Hong Kong in the South China Sea. Husky holds a 40 percent working interest in the field, which began production in 2002.

The Wenchang field is producing from 30 wells in 100 metres of water into a floating production, storage and offloading (FPSO) vessel stationed between the fixed wellhead platforms.

Blended crude from the field averages approximately 35 API; similar to the Minas blend (Indonesian crude benchmark).
