Saga Texas Electrical Load Costing
This month we added Oil and Water data to wells and compared fluid variations to electrical demand variations
Steady: Majority time spent in pump off state w 125KW load cycling. One 2 hour outage. [~200KW, 60% Volatility]
Changes: TXL Steady; Foster 10 had fluid data superimposed on KW data and correlations were evident.
Load Vairation: Irregular and very frequent 300KW cycling.on/off pattern. [1400KW, 14% Volatility]
Solid: Good operation. [750KW, 24% Volatility; World 2 50KW, 10%]
Equipment offline: 1 anomaly at 5am Sep-10. [175KW, 347 Volatility]
Mostly Steady: 2 meters shown, with 30KW and 70KW avg loads. Cycling on/off. Changes: TXL Steady; Foster 10 had fluid data superimposed on KW data and correlations were evident. [30KW, 33%; and 70KW, 60% Volatility]
Rrecurring issue: Drop in load of 400KW happening. Opportunity to improve this large load? [1200KW, 17% Volatility]
Andrews / University
Regular cycling. Andrews 1 has some large spikes and drops, average is 20KW. Andrews 2 peaks at 35KW with outages on Aug-8th, 11th, 12th but steady cycling other times. [20KW, 14%; 35KW, 57%]

Volatility Percentage: A/B
Volatility Ratio: A/C
1. “Volatility Percentage” is the percentage Volatile Power (A) over Total Power (B).
2. “Volatility Ratio” is the Volatile Power (A) over Base Power (C)
Sept-1 extended 135KW off for 8 hours. Then ramp to 240KW, then 24 hour ramp down back to original base of 210 KW
Sept-7 @5p total field outage for 2hrs. Recovery spike by 30KW to 235KW. Visit VFD programming for better peak control.
Base increased by 25KW for 24 hours. Looks to be in correlation with ramping of water injection.
Approximately 48hrs of additional 200 BBLS of fluid per day with no affect in electrical load or oil cut.
This graph has fluid data date matched to KW data (no 1-day lag on fluid)
2 ESPs: 80 HP & 100 HP. 12 PJs: 40-50HP per well. 1 Injection Pump: 250 HP. Total Nameplate: 730 kW

South COWDEN - TXL – Sept
A=146 B=152 C=6
Septt’15 KLD Field Survey Results:
Erratic equipment behavior. At Sep-7 @7pm it came on only 75% of prior power level for 30 minutes. Then off for the typical 3.5hrs, then ON for a double cycle (10 hours instead of typical 5 hours). Looks like an ESP is running the well dry too quickly.
Sep-18 ON for a double cycle again
Huge on/off hits of 146KW is energy inefficient and hard on equipment
4 water pumps, 1 pump jack
