Black Mamba
Sucker rod stabilizer, centralizer, and guide.
Complete Rod Control is now possible! Sucker rod buckling and instability during compressive moments is in the past.
Complete Rod Control allows for pushing the pump, pumping the curve, and eliminating loss of down-hole plunger travel through perfect, ideal behavior and control of the rod string.
Black Mamba Rod Lift can assist in the placement and count of Black Mamba Helical Stabilizers by way of our proprietary iterative algorithms which analyze SPM, Rod Design, Deviation, and Stroke to populate maximum potential compressive loading and stresses leading to buckling; this compression analysis is much more specific than the outputs of predictive sucker rod programs and guarantees extended run times.
Keep wells pumping - reliably.
Design Benefits
- Bending Moment Mitigation A patent-protected centralizer which truly reduces fatigue cycles on the sucker rod, preventing axial deflection and excessive, unintended localized stress along the sucker rod body.
- Erodible Wear Volume (EWV) Greater EWV than any other centralizer on the market, leading the industry in product life and sucker rod protection. Part-for-part, nothing compares.
- Fluid Flow Bypass Area A single fin allows for 70% more fluid flow area than legacy product. Bye-bye fluid turbulence. Further, the singular fin and helical design provide unmatched performance Progressive Cavity pumping.
- 360 Degree Protection The Black Mamba sucker rod stabilizer (its more than a sucker rod guide!) circumferentially occupies the free space around the sucker rod, allowing sucker rod flexibility, but taking the space of potential movement.
- Paraffin Movement With a single-fin helically surrounding the sucker rod body, paraffin continues to move up the well-bore.
CFD
CFD analysis allows us to understand fluid flow behaviors around sucker rod guides and molded sucker rod stabilizers during the down-stroke of the rod lift pumping cycle. As fluid rushes past sucker rod guides, chaotic flow patterns occur which can induce erosion, corrosion, and lack of protection beyond the sucker rod guide regarding chemical corrosion inhibitors.
Often rod parts and sucker rod failure occurs at the edge of sucker rod guides. Sucker rod guides are large, foreign objects inhibiting ideal fluid flow patterns and can create areas of concern due to a variety of reasons: Fluid Turbulence, Bending Moments (Compression on Legacy Sucker Rod Guides) and lack of inhibitor to name a few.
Take a look below to learn more. Stagnate, low velocity flow patterns are consistent with foreign legacy 4-fin sucker rod guide design.
A few notes:
- Slant Vane Design – Introduced nearly 40 years ago, slant vane sucker rod guides do a great job at moving paraffin but do redirect fluid flow at a different vector.
- Symmetrical Straight Vane Design – Pressure drop is observed behind the sucker rod guide, creating stagnate fluid flow and low velocity/fluid movement.
- Asymmetrical Straight Vane Design – Chaotic fluid turbulence is observed as fluid crashes back together behind the sucker rod guide.
- Unique Products – Various sucker rod guide designs can feature high EWV but have gnarly fluid flow patterns.
- Black Mamba – Less restrictive than a 3/4″ slim hole coupling, this design provides the highest EWV on the market with the lowest flow turbulence.
Erodible Wear Volume & Bearing Surface Area
Erodible Wear Volume is the volume of plastic outside of the sucker rod coupling. Our products offer nearly 3x the volume of available plastic before the guide is worn to the coupling diameter.
Bearing Surface Area is highlighted in green on the image to the left. As BSA is increased, the side-load is acting on a larger surface area, REDUCING the compressive stress on the plastic.
Optimizing EWV and BSA together, along with sound material science and manufacturing quality parts is the best way to enhance product and system life.
