Black Powder and Innopipe

“Black Powder” is a catch-all term for solids residues found in all manners of oilfield tubular materials, from casing to piping to transmission lines. Black Powder is seen as an impediment to safe and economic operations of gas pipeline operations. OilPro customer Mr. Peter van Beugen, M.Sc. University of applied Physics, Delft, the Netherlands and Managing director of Pipesurvey International, the Netherlands, identifies Black Powder issues well in his paper New Frontiers in Black Powder Removal, Causes, Consequences and Combat, including a Case Study, published in:
The Pipeline and Gas Journal, March 1st, 2006.  

Van Beugen  identifies causes of formation/ They include sour gas, liquids and just accumulations of mill-scale. Effects of black powder in pipeline systems range from:accumulations of black powder in low spots (sometimes caused by pigging, and potentially leading to false smart-pig wall thickness readings); wear on elastomers in the system or on pigs; irregular pig velocities leading to data loss and tool damage; decreased efficiency; decreased product quality; downstream equipment fouling. 

Black Powder is a problem because it can damage all sorts of components in a system. Conventional filtration, separation and magnetic solutions offer the cure while, for over 20 years, Innopipe offers the prevention of the problem in the first place by removing the liquids required for black powder formation. Innopipe  has no filters to plug, no filter element changes, no reduced production, no restrictions, less stress on interdependent systems, less horsepower losses, while remaining bi-directionally piggable.

The constituents of Black Powder range from metallic elements to bacteria-produced material to silica and calcium. These abrasive or corrosive materials tend to form in the presence of liquids and manifest themselves often as iron sulfides and iron oxides. Therefore, strategic placement of the Innopipe in your transmission system can prevent the formation of black powder before it becomes a problem.

Although Innopipe offers an excellent solution for mitigating formation of the powder, it should be understood that a while pigging intervals likely can be reduced, they will still be necessary, and Innopipe efficiency can be further enhanced by the inclusion of additional filtration systems such as magnetic solutions, integrated with our system. Your Innopipe solution provide will be glad to walk you through these available system options.

Steam distribution System phase management and Innopipe
SAGD (Steam Assisted Gravity Drainage) as well as Expanding Solvent-SAGD (ES-SAGD) and Cyclic Steam Stimulation (a.k.a. “Huff and Puff”) use steam generators to provide the steamflooding required for Enhanced Oil Recovery (EOR)
Steam generators are meant to provide vapor, but can unintentionally also make liquids doe to heat loss and condensation. Producers pay particular attention to insulation of steam lines for this reason. Steam Pressures trend in quite high pressure ranges (2,700 psig and up) and temperature ranges. Innopipe design easily adapts to such design standards.

Common SAGD liquids problems:

  • Phase Splitting
  • Condensation Induced Water Hammer (CIWH)

Phase Splitting

This variability can cause phase changes from vapour to liquid, resulting in what is known as “Phase Splitting”, seen in piping tees and branching causing unintended separation. Phase splitting in turn results in inconsistencies in the delivery of steam to the reservoir and commensurate interference ” with the optimization of steam-injection rates, oil recovery, project economics.”  (per
This variability can be dealt with using steam separators which are expensive due to the required size when engineered using conventional 2 phase separation methods.
Innopipe offers an economical option due to its relatively small size, improved efficiency and much shorter retention time requirement.

Condensation Induced Water Hammer (CIWH)

CIWH, also know as “Steam Hammer” is described by Jeff Dancey of Baker Engineering and Risk Consultants, Inc.. Water hammer can:

  • rupture piping, 
  • Cause valve failure
  • require large expansion tanks
  • require surge-relief, pressure-relief and/or control valves
  • cause slug  flow,
  • cause steam blow-through to producer well

Innopipe is custom designed, yet built quickly, to match your piping’s specifications and built as a fitting for smaller diameters, or a smaller-than-conventional pressure vessel for larger line sizes.
These can be built to be either piggable or non-piggable also, depending on location and preference.

We look forward to helping you optimize delivery of steam to your system.
