Water treatment systems in the North Sea differ from those in the deepwater Gulf of Mexico (GOM). This paper provides a detailed understanding of these differences and provides insight into the design of water-treatment systems in general. A recent webinar focused on hydrocyclones and their application for offshore oil and water separation. The discussion includes fundamental science, practical considerations, implementation and field experience. The author reviews advances in produced water treatment, particularly offshore, since the 1960s.
The well count and completion intensity of US tight oil and gas operations have grown in recent years, and rising pressure from environmental regulations means that produced water management has become a key focus for operators. While storage and logistics are critical elements of the viability of water reuse, if the water chemistry is not fit for gel fracturing formulations, it will not matter how much is stored in centrally located impoundments. This paper reports on performance of an advanced MVR system in north-central Texas. With inconsistent inlet water quality being the rule rather than the exception, sizing and operational considerations of the treatment system components must vary accordingly to make the most economic sense. The demands for the fresh water used in many hydraulic fracturing operations are placing pressure on water sources in some regions of the United States.
According to a new report from the EIA, the volume of natural gas reported as flared reached its highest average annual level in 2018, 1.28 Bcf/D. With production soaring in the Bakken, Permian, and Eagle Ford plays, North Dakota and Texas accounted for more than 80% of that total. After a planned acquisition of Goodnight fell through, private equity firm Tailwater Capital is boosting its total investment in the water midstream company to more than $500 million. Goodnight recently signed five long-term contracts with producers in the Delaware Basin and the Bakken. A new paper from ADI Analytics examines the circumstances in which natural gas could become an attractive method for fueling oilfield equipment.
Enhanced oil recovery processes, particularly offshore, create challenges for produced water treatment. Higher oil prices has created increased interest in chemical enhanced oil recovery (CEOR) using polymers, surfactants, and alkalis. This technology poses some special challenges, especially around water treatment.
Oil and gas extraction using water has opened up new hydrocarbon resources. However they can produce four times more salty water byproduct than oil. Desalination in shale gas and polymer-flood EOR remain niche markets for lowering cost and improving production. Aker Solutions and FSubsea have agreed to a joint venture, named FASTSubsea, to help operators increase oil recovery. High-concentration polymer flooding can improve oil-displacement efficiency but separation of oil/water mixture becomes more difficult because of emulsification.
A recovery in the energy industry is key to the oilfield water sector in the Permian. But the industry must address issues such as further research, regulatory changes, and technology. Cutbacks in oil and gas production and drilling and completions will result in a decrease in produced water and will also lead to a reduction in water infrastructure investment. The fact sheet, in conjunction with other IPIECA water management guidance, is intended as a guide to explore opportunities to reuse produced water. GWPC releases its third produced water report.
The company announced both contract awards simultaneously. The new contract awards could be worth up to $800 million. The FPSO, MODEC's largest size of "gas FPSO" to date, will be the first application of the contractor’s M350 Hull, a next-generation newbuilt hull for FPSOs. The deal for ConocoPhillips’s northern Australian portfolio will help the Australian company boost its position in the country’s gas market, as it gains majority ownership in a set of key assets including Darwin LNG and the Barossa project. Drones are becoming an important tool for energy companies looking to improve on-site safety and operational efficiencies, and the industry is looking for the best way to maximize their value.
The North Caspian Project in Kazakhstan covers the Kashagan, Kairan, Aktoty, and Kashagan South West fields. A recovery in the energy industry is key to the oilfield water sector in the Permian. But the industry must address issues such as further research, regulatory changes, and technology. Centennial said in its 10-Q report for Q1 that the economic downturn increased the likelihood that the transaction would fail to close by its original timeline. Sourcing water, flowback water services threatened as D&Cs decline. Cutbacks in oil and gas production and drilling and completions will result in a decrease in produced water and will also lead to a reduction in water infrastructure investment.
