Oilfield Fluid Loss Prevention



One challenge faced by the oil industry is maintaining the structural integrity of the well while crude oil is being removed. This is done by lining the well with a compound that essentially prevents the well from caving in on itself. This ‘cement’ must endure a wide range of temperatures and pressures and must be both environmentally and economically viable. The Celanese Premiol line of products hasbeen proven perfect for this application.



Celanese Introduces Premiol Fluid Loss Control Additives for Oilfield Cementing Applications
New technology initiative to offer new levels of temperature performance, environmental friendliness and cost control in off-shore, mid-range and deep well applications

The emulsions and polyvinyl alcohol (PVOH) business of Celanese has announced a new initiative to develop high performing chemistry for oilfield operations aimed at meeting current challenges for improved performance and economics. Based on intensive R&D, Celanese’s new Premiol™ line of performance chemicals will target a range of applications initially starting in the areas of cementing and drilling. The first offerings in the Premiol line include three fluid loss control additives for off-shore, deep well and mid-range well cementing applications. Celanese is supporting the new product lines with in-house cementing and drilling fluid labs and experienced personnel dedicated to oilfield customers and optimal performance of Premiol products in the field.

According to Mike George, Global Marketing Manager, Innovation Segment, the Premiol initiative is part of Celanese’s on-going effort to create value for customers from its strong technology position across a range of chemistries. “The introduction of these first Premiol lines of oilfield performance products represents a new beginning in the oilfield industry for Celanese.

Building on a thorough analysis of market trends and needs, we are engaging in an intensive R&D effort to develop new products and to tailor solutions that will resolve issues in productivity, performance, cost control, environmental compliance, safety and more,” George said. “These first three products have been evaluated by oilfield service companies and by independent laboratories. It is clear that they will create real value in the oilfield applications they serve,” George emphasized.

Three new fluid loss control lines
Three new technology pushes from Celanese in the area of fluid loss control for cementing operations are represented by three distinctive product lines. These include: Premiol DWC high temperature performance fluid loss control additives for deep well cementing; Premiol OSC high performing, environmentally friendly fluid loss control additives for off-shore cementing; and Premiol MRC, a line of versatile, cost-effective fluid loss control additives for mid-range well cementing applications. Each of these lines begins with a single product, with additional products to follow in the coming months.

Premiol DWC-50: High performance, “all temperature” technology
Premiol DWC-50 is a powder-form fluid loss control additive for deep well applications that delivers high temperature performance (up to 150ºC) at cost levels below traditional high molecular weight polymers. At the same time, this advanced additive demonstrates excellent, cost-effective performance at low temperatures (50ºC to 60ºC). With a single product that functions across a wide range of conditions, the oilfield service industry can consolidate inventory of fluid loss control products.

Premiol OSC-10: A highly concentrated, environmentally sound alternative
Premiol OSC-10 is a proprietary water-based, fluid loss control additive designed for offshore cementing or onshore applications where liquid delivery is desired. This product delivers performance equivalent to the best of traditional low temperature, mineral oil-based fluid loss control agents. The aqueous nature of Premiol OSC-10 offers a better environmental profile than typical mineral oil-based products. The defining feature of this product is its high concentration that allows for economical delivery and cost efficiency when compared with competing technologies.

Premiol MRC-33: Predictable performance with excellent economics
Premiol MRC-33 is a powder-form fluid loss control additive for mid-range temperatures in oilfield cement applications. At temperatures between 75ºC and 120ºC, this product provides the excellent fluid loss and preferred, low surface rheology without settling. These benefits provide the oilfield industry with a cost effective alternative to current polymer technologies.

Celanese in the oilfield
Celanese technology is being considered for a broad range of applications in the oilfield industry, with a current focus on cementing and drilling. In the future, Celanese will support oilfield customers across a spectrum of downhole applications, with target areas including acidizing, stimulation, workover, water management, and fracturing.

The R&D effort is supported by in-house cementing and drilling fluid labs and experienced personnel dedicated to oilfield customers and their applications. The primary mission of this group is the development of laboratory and field data to ensure optimum performance and cost advantages are made available with leading-edge technology.
