Production begins at Dukouhe-Qilibei

PetroChina has started production at Dukouhe-Qilibei, the last of three major sour gas fields in its high-sulphur Chuandongbei cluster in southwest China. The Dukouhe-Qilibei field’s hydrogen sulphide content reaches up to 17.1%, the highest of any integrated gas field currently in production in China. PetroChina confirmed that commissioning was completed on 30 June, with the Dazhou gas processing plant now running at its full design capacity of 4 million cubic metres per day. The Chuandongbei cluster originally comprised three key sour gas block: Luojiazhai, Tieshanpo, and Dukouhe-Qilibei, and was initially developed under a partnership between Chevron and PetroChina, with Chevron leading the early-phase project development. However, Chevron exited the project in 2020, transferring full control to PetroChina following operational delays and cost challenges. PetroChina says that the completion of Dukouhe-Qilibei solidifies its capabilities in handling high-sulphur content gas fields and marks a significant boost to China’s domestic gas supply, particularly in inland regions with growing industrial demand.

Agreement signed for gas separation complex

A formal signing ceremony has been held between senior company executives from KMG PetroChem, Tecnimont and the Kazakh government for the construction of the new Tengiz Gas Separation Complex (GSC) project. The ceremony was held at KMG PetroChem headquarters, in the Atyrau region of Kazakhstan. The Tengiz GSC project’s scope of work includes engineering, procurement, construction and commissioning works, with Tecnimont mainly responsible for the EPC works. Completion is expected by the first quarter of 2029. Once completed, the gas processed by the GSC will feed the Silleno petrochemical plant, another project currently being executed by Tecnimont in the region. The GSC is designed to recover at least 98% of ethane from dry gas, while the Silleno complex is expected to deliver high-quality petrochemical products. KMG PetroChem is a fully owned subsidiary of Kazakhstan’s national oil and gas company KazMunayGas.

BADC signs import deals

In addition to the above deal with Morocco, the Bangladesh Agricultural Development Corporation (BADC), part of the Bangladesh Ministry of Agriculture, has signed a contract to import both triple superphosphate (TSP) and di-ammonium phosphate (DAP) fertilisers from Malaysia. The agreement was signed on 17 July 2025 in Kuala Lumpur by Mohammed Ruhul Amin Khan, chairman of BADC, and representatives of Selcra Niaga. Under the contract, BADC will import 280,000 tonnes of TSP and 280,000 tonnes of DAP from Malaysia. According to BADC officials, this landmark deal is expected to play a crucial role in ensuring the timely delivery of non-urea fertilisers to farmers. The move aims to strengthen Bangladesh's efforts toward building an efficient and sustainable agricultural system.
