Sour field development plans are ongoing throughout the Middle East, given the gas demand and none more so than in the UAE where priorities in Adnoc’s integrated gas master plan include tapping into deep and sour gas reserves, improving the processing capacity of the Al Hosn Shah plant by 50 % to 1.5 billion cft/d and deploying innovative CCUS for EOR. Moreover, Al Hosn Gas has recently been appointed by ADNOC to appraise and develop the offshore Hail and Ghasha fields which are scheduled to come onstream by 2020. These fields are in water depths up to 15 metres but are in a very sensitive marine protection zone. Also plans continue for the development of the Shuwaihat field.
Within this region, Saudi Aramco and their Fadhili gas project with a projected value of $13.3 billion due for completion in 2019, will treat gas from onshore and offshore fields to the tune of 17 bcf/d by 2020. This project together with Wasit and Midyan, two other major new gas developments and the offshore Hasbah field will add to focus on KSA’s sour gas plans.
2017 will also see the start up of Qatar’s Barzan Project which will add over 1.4bcf/d together with significant additional increases in field condensate, ethane, propane, butane and sulphur.
PDO are moving forward with the Rabab-Harweel integrated project with the sour gas from Rabab injected into the sour oil Harweel field to enhance recovery. The YibalKhuff project, which is technically one of the most complex ventures undertaken in Oman, will require a sizeable investment in sulphur removal techniques. Also plans at Budoir for the first ever water injection into a sour oilfield are under review following the discovery of additional gas reservoirs.
Iran is also operating offshore drilling at Pars Phase 14 and will expect to produce 56.5 mln cm/d of sour gas.
A recent announcement from KOC involves targeting oilfields to produce 4 mlnbppd by 2020 and within this plan there are several gas considerations. Additionally sulphur treatment facility contracts have been recently awarded at Kuwait’s Sabriya and East Raudhatain gas treatment plants.
It could be said that this region is concentrating on gas sweetening technologies to deliver the ever increasing volume of sales to meet collective demand but they are not alone internationally given the recent announcement from Chevron of the expansion of the Tengiz development in Kazakhstan. This Future Growth Project will use sour gas injection technology to ramp up production. Lukoil has commenced the construction of the Kandym gas processing complex in Bukhara, southwestern Uzbekistan. Elsewhere Malaysia’s SapKen have been awarded a US$311 million project to install a 36”, 18 km sour gas pipeline in Mexico.
The technologies involved in sour field management and production are always progressing and the latest developments across the whole management spectrum including observations on capturing CO2 from sour gas processing facilities for use in EOR will be included in the SOGAT Conference Programme. This programme focuses on presentations primarily from operators case studies thus providing delegates with invaluable knowledge and data to employ in their own environments if required.
As usual practical Workshops on topical issues in these areas will be presented in the first two days of SOGAT 2017 and will cover: Sour Oil & Gas Process Optimisation; Amine Treating; Improving SRU Cost Efficiencies and Associated KPI’s; and Benefits of Hybrid Solvents for Mercaptan in Natural Gas.
The SOGAT Exhibition will see the world’s leading vendors and suppliers returning again and so SOGAT 2017 will continue its well known trend and reputation, as the international event that provides a one stop review of all the latest developments in global sour hydrocarbon management.
