SPOC Automation Energy Savings Presentation DUG Eagleford

  1. 1. PRODUCE MORE. SPEND LESS Energy Savings Using Variable Frequency Drives (VFDs) On Beam Pumps Bryan Lile, Texas Regional Manager
  2. 2. PRODUCE MORE. SPEND LESS SPOC Automation: Who Are We? • Oil and Gas • Leader in Oilfield Variable Speed Drives • Specialists in Optimizing Pump Control with 200+ years of experience • 15+ Years in business • Family Owned • Based in Trussville, AL
  3. 3. PRODUCE MORE. SPEND LESS Energy Savings Using a VFD • VFD has Power Factor up to .97, eliminating penalties
  4. 4. PRODUCE MORE. SPEND LESS Energy Savings Using a VFD • Power Factor up to .97 eliminates penalties • Can use NEMA B motors to save 3-5% additional energy
  5. 5. PRODUCE MORE. SPEND LESS Energy Savings Using a VFD • Power Factor up to .97 eliminates penalties • Can use NEMA B motors to save 3-5% additional energy • VFDs eliminate regeneration
  6. 6. PRODUCE MORE. SPEND LESS Energy Savings Using a VFD • VFD can eliminate regeneration • When the heavier side of an unbalanced beam is moving up, the motor uses power • When the heavier side of an unbalanced beam is moving down, the motor becomes a generator • The generator sends power back into the electric grid • The utility does not give credit for this generated “negative” power
  7. 7. PRODUCE MORE. SPEND LESS Eliminating Wasted Energy in Regeneration • Most Beam Pump VFDs use Dynamic Braking to deal with regeneration. • Brake Resistors increase energy consumption 15-30% • Iron Horse drives do not require resistors
  8. 8. PRODUCE MORE. SPEND LESS Eliminating Wasted Energy in Regeneration • The area in the green is typical lost as heat in a VFD with a brake resistor • The area in the green is given back to the utility with a starter panel Wasted Energy
  9. 9. PRODUCE MORE. SPEND LESS Eliminating Wasted Energy in Regeneration • Recent Well Test by SPOC Automation with Laredo Energy in Odessa, 7.1 SPM, 50HP motor • With starter: 9.7KW of energy • With VFD: 7.3KW of energy 25% reduction in energy cost $4000 per year savings
