Thailand's PTT Exploration and Production said it plans to accelerate the development of its portfolio of exploration discoveries offshore Malaysia, but at home the company is still at loggerheads with Chevron over access permission to the Erawan gas field.

The company has been very successful this year discovering new fields offshore Sarawak, Malaysia, and said in its latest quarterly financial results that it plans to accelerate the development of the discoveries including Dokong-1, Sirung-1, Kulintang-1 and Lang Lebah "to increase reserves for supporting long term growth".
