Integrated Solution for Oilfield Produced Water

In the wave of high-quality development in the energy industry, the efficient treatment and resource utilisation of oilfield produced water is both an environmental necessity and a core issue in ensuring stable oilfield production. With its deep technical accumulation and innovative practice in water treatment, SINOKLE provides a highly efficient, stable and adaptable full-process solution for oilfield produced water treatment, making it a trusted partner in the industry.

1. Core Process: A Precise Transformation from Produced Fluid to Reinjection Water

Targeting the complex characteristics of oilfield produced water, SINOKLE has developed an integrated treatment process of "three-phase separation + cyclonic dissolved-air flotation + advanced filtration", achieving efficient conversion from produced fluid to qualified reinjection water:

1. Efficient upstream separation: the three-phase separator completes the initial separation of oil, water and solids, reducing the load on downstream treatment;

2. Two-stage cyclonic dissolved-air flotation (CDFU): a first-stage plus second-stage series cyclonic dissolved-air flotation technology efficiently removes floating and dispersed oil from the water, greatly reducing the oil content while recovering the floating oil for resource reuse;

3. Customised advanced treatment: three differentiated schemes are provided according to the permeability requirements of different formations:

a. High-permeability formations: a single-stage KFM active filter media filter quickly brings water quality up to standard;

b. Low-permeability formations (A2): two KFM active filter media filters in series further improve effluent precision;

c. Ultra-low-permeability formations (A1): a combination of KFM active filter media and a modified inorganic membrane filter meets the stringent reinjection requirements of ultra-low-permeability formations.

This process both guarantees the stability of treatment performance and adapts flexibly to project scenarios, truly "applying measures suited to local conditions".

2. Technical Advantages: Hard-Core Strength Sets the Industry Benchmark

SINOKLE's core competitiveness stems from continuous investment in technological innovation and an extreme pursuit of quality:

• Efficient oil removal: the two-stageCDFU process combined with KFM active filter media can reduce the oil content of produced water to an extremely low level, far better than industry standards;

• Strong adaptability: modular solutions are provided for high-, low- and ultra-low-permeability formations, with no need for repeated modification, reducing project costs;

• Stable and reliable: the equipment runs smoothly with a high degree of automation, reducing manual intervention and safeguarding the continuity of oilfield production;

• Green and environmentally friendly: floating oil is recovered and reused with no secondary pollution, achieving recycling of water resources and supporting the oilfield's green, low-carbon transition.

3. Value Empowerment: Injecting Momentum into the Oilfield's Sustainable Development

Against the dual background of the "dual carbon" goals and energy security, SINOKLE's produced water treatment solution not only solves the oilfield's environmental pain points but also creates multiple values:

• Ensuring stable production: qualified reinjection water effectively maintains reservoir pressure, supporting long-term stable production;

• Reducing costs and increasing efficiency: modular design and efficient operation lower O&M costs and energy consumption, improving project economic benefits;

• Meeting compliance standards: precisely matching environmental regulations and reinjection water quality standards, avoiding environmental risks;

• Technology empowerment: providing the technical foundation for the water treatment link of the oilfield's digital and intelligent transformation.
