SPOC Automation Energy Savings Presentation DUG Eagleford
- 1. PRODUCE MORE. SPEND LESS Energy Savings Using Variable Frequency Drives (VFDs) On Beam Pumps Bryan Lile, Texas Regional Manager
- 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. PRODUCE MORE. SPEND LESS Energy Savings Using a VFD • VFD has Power Factor up to .97, eliminating penalties
- 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. 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. 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. 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. 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. 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
