The diversity of our products and cement additives enables us to design and construct various types of cement slurries, ranging from lightweight to heavyweight, addressing challenges encountered during drilling, operation, and remedial operation in the oil and gas fields. This flexibility allows us to align with Key Performance Indicators (KPIs) set by our clients, and further positions us as best-in-class service and solution providers to domestic and international clients.



 Parallel to our Cementing Services, our Stimulation Services commenced operations in South Pars gas projects and oil wells in the Persian Gulf waters in 2009. Leveraging the capabilities of our company’s proprietary equipment, such as On-Platform/Onshore Mixing and Pumping Packages, we have been actively contributing to the client’s requirement. The operational bases on Kish islands and Ahwaz, coupled with the HCl acid storage facility at Pars Asalouye port, have consistently provided 24/7 support for Acidizing and well stimulation projects in both onshore and offshore fields.

A key distinguishing feature of our Stimulation Services business line is the possession of a proprietary well stimulation vessel equipped with an Acid On the Fly system. This cutting-edge technology positions us competitively on the global stage, offering top-notch quality and modern equipment within the field of Stimulation Vessels.

In fact, we proudly own the unique well stimulation vessel in the Middle East that incorporates a comprehensive array of capabilities, including High-Pressure Pumping units, Acid and Chemical Storage and Handling, a Well Clean-Up Burner and Choke Manifold System, a 180K N2 Pump along with 7000-gallon N2 Tank. This unique combination of features highlights our commitment to providing advanced and comprehensive solutions in the field.



Since the beginning of our Drilling Fluids Services in late 2022, coinciding with the South Azadegan project’s launch, we have harnessed the expertise of our skilled professionals to optimize Dana Energy’s internal drilling operations. As we expanded our operations to include the West Paydar 3 project and other exploration and production activities, our in-house team has been committed to delivering comprehensive drilling fluid and waste management solutions across all projects.

Successfully completing drilling fluid and supplementary fluid services for 7 wells in South Azadegan, along with 3 maintenance wells, and 6 wells in West Paydar 3, our team continues to provide engineering, design, and implementation expertise in drilling fluid management. This detailed approach ensures the utmost satisfaction of our clients.

In parallel with our drilling fluid services, we have designed and implemented our first drilling waste management complex, featuring:

  • A 900-barrel Buffer Tank equipped for mixing, aerating, and sedimentation-based solid particle separation.
  • A state-of-the-art, fully automatic dewatering unit for chemical separation and wastewater purification.
  • A high-pressure automatic filtration system based on particle size separation technology.
  • A versatile pump array, including Centrifugal, AODD, Cavity Screw, Dosing, submersible, and Sewage Pumps, capable of handling fluid and sewage at rates ranging from 1 to 100 gallons per minute.
  • A workshop container outfitted with maintenance equipment for on-site rig support.

Utilizing this equipment enables the implementation of a Zero Discharge method, initiated with the exploration management project in Changuleh 2 well. We are currently advancing the construction and commissioning of two additional drilling waste management sets to equip all our rigs.

To strengthen our support for ongoing projects at the Ahwaz base, we have optimized warehouse services, ensured timely material delivery, and established a quality control laboratory for drilling fluids. This strategic enhancement ensures high-quality service delivery.
