Understanding Lease Operating Expenses (LOE) in Oil and Gas

What LOE Includes

Lease operating expenses cover every recurring cost of keeping a well in production. Pumping costs (electricity for rod pumps or submersible pumps), chemical treatment (corrosion inhibitors, paraffin treatments, scale control), well maintenance (rod and tubing repairs, pump replacements), water disposal (produced water hauling or injection wells), gathering and transportation fees (pipeline or trucking to market), compression (for gas wells), and regulatory compliance costs.

These aren't one-time costs. They recur monthly for the entire producing life of the well. Understanding LOE is as important as understanding drilling costs, because LOE determines whether a low-rate well remains economic or gets plugged.

Typical LOE Ranges

Conventional vertical wells in Oklahoma: $5-$15 per barrel of oil equivalent (BOE). The low end is a trouble-free well on rod pump with nearby pipeline access. The high end involves older equipment, high water production, or remote locations requiring trucking.

Unconventional horizontal wells: $10-$25 per BOE. Higher costs reflect more complex downhole equipment, greater water production volumes, and more extensive surface facilities.

Stripper wells (producing less than 15 BOE/day): LOE per barrel rises sharply as fixed costs are spread over fewer barrels. A well producing 3 BOE/day might have LOE of $30-$40 per barrel, making it marginal even at $70 oil.

How LOE Affects Your Returns

Your monthly distribution = Revenue - LOE - Severance Tax. If your well produces $8,000/month in gross revenue and LOE is $2,500, you net $5,500 before taxes. As production declines and LOE stays relatively fixed, that margin shrinks. Eventually, the well reaches its economic limit, the point where LOE equals revenue and there's nothing left to distribute.

Smart operators aggressively manage LOE. They negotiate competitive service contracts, optimize chemical programs, and invest in automation (SCADA monitoring, automatic well control) to reduce labor costs. The difference between a $7/BOE operator and a $14/BOE operator is significant over the life of a well.

Workover Costs vs. Routine LOE

Workovers are periodic interventions that go beyond routine maintenance: pulling and replacing rods and tubing, re-stimulating the formation, isolating water-producing zones, or converting from one lift method to another. Workovers cost $20,000-$200,000+ depending on scope and are deductible as operating expenses in the year incurred.

Good operators plan workovers strategically, timing them when production has declined enough that the improvement justifies the cost. A $50,000 workover that restores 10 barrels per day of production pays for itself in a few months at $75 oil.

What to Ask Before You Invest

Before investing in any program, ask the operator for historical LOE data on their existing wells. Compare those numbers against basin averages. If their LOE per barrel is significantly above the norm, find out why. If they won't share the data, that's your answer.

Low and predictable operating expenses are what separate a good well from a break-even one over the long run.
