In oil drilling operations, the performance of drilling fluids directly impacts drilling efficiency, wellbore stability, and reservoir protection. As a key component of Hoda Chemical’s five core product lines, polyacrylamide cellulose (PAC) is emerging as the “rheology control expert” in the global drilling fluid market, thanks to its exceptional heat and salt resistance and highly effective loss-reduction capabilities.
Performance Advantages: The Upgraded Alternative to Traditional CMC
Polyionic cellulose is a water-soluble anionic polymer derived from chemically modified natural cellulose. As an upgraded product of sodium carboxymethyl cellulose (CMC), it comprehensively surpasses its predecessor in multiple performance metrics:
- Outstanding Temperature and Salt Resistance: It can withstand temperatures of nearly 150°C and operates within a wide pH range of 3–11, consistently delivering viscosity-enhancing and loss-reduction effects in systems ranging from fresh water and seawater to saturated brine.
- High-efficiency loss control and viscosity enhancement: It forms a dense, thin filter cake on the wellbore wall, effectively reducing the infiltration of drilling mud into the formation. In 4% brine and saturated brine drilling mud, its performance outperforms traditional CMC.
- Strong inhibition and wellbore stabilization: It effectively delays the hydration, swelling, and dispersion of shale, playing a crucial role in stabilizing wellbores in formations prone to collapse.
Market Applications: Comprehensive Coverage from Onshore to Offshore
PAC is widely used in various oil drilling projects and performs particularly well in the overseas markets where Hoda Chemical has focused its efforts:
- South American Market: Addressing the high-temperature and high-pressure challenges of deepwater sub-salt projects in Brazil, high-viscosity PAC precisely regulates drilling fluid rheology to ensure the safety of deepwater drilling operations.
- Middle East Market: For drilling through salt-pancake formations in Saudi Arabia, the UAE, and other regions, polyacrylamide cellulose’s(PAC) salt tolerance effectively addresses complex formation conditions.
- Central Asia Market: To meet shale control requirements in large oilfields such as Tengiz and Kashagan in Kazakhstan, PAC’s strong shale control performance provides robust assurance for wellbore stability.
Market Outlook and Hoda Chemical’s Advantages
According to market research data, the global market size for PAC used in oilfield drilling fluids was approximately 4.22 billion yuan in 2024 and is projected to reach nearly 4.88 billion yuan by 2031. As global deepwater oilfield development and shale oil and gas exploration continue to gain momentum, the market potential for PAC will be further unlocked.
