the year 2015 also experienced volume declines and added margin pressure as crude oil prices continued to decline . previously , a key factor in unit margins was the value difference between crude oil supplies in the mid-continent region of the united states versus crude oil supply costs in the eastern region of the united states . the company was able to capture some of this value difference by shipping crude oil from the texas gulf coast to points east . due to competitive pressures during 2014 , the opportunity for the company to capture this location-based unit value difference evaporated which reduced earnings . further , depreciation charges increased as new equipment was added and driver commissions increased in 2014 and 2015 as a result of driver shortages in 2014 and longer hauls in 2015 , necessitated by the competition to retain volumes . an adverse claims experience increased insurance costs in 2015 but this experience cycle is not expected to recur in 2016. initially in 2015 , operating earnings benefited from reduced fuel costs but this advantage has been largely lost as competitive pressures necessitated passing such savings back to suppliers in the form of higher purchase prices . historically , prices received for crude oil have been volatile and unpredictable with price volatility expected to continue . see ‟item 1a , risk factors – fluctuations in oil and gas prices could have an adverse effect on the company ” . 19 - transportation the transportation segment revenues and operating earnings were as follows ( in thousands ) : replace_table_token_12_th ( 1 ) represents the percentage increase ( decrease ) from the prior year . the company 's revenue rate structure includes a component for fuel costs such that fuel cost fluctuations are largely passed through to the customer over time . to illustrate , a calculation of revenues net of fuel cost is presented below ( in thousands ) : replace_table_token_13_th revenues net of fuel costs appear relatively flat while reported mileage as shown above has been decreasing from 2013 to 2015. this apparent paradox results because of rate increases necessitated by higher driver and equipment costs in the more recent years . the operating earnings trend line has declined since 2013. this is caused by two primary factors . first and most recently , mileage is reduced reflecting a drop off in demand originating in the third quarter of 2015. second , maintenance expense and depreciation following new equipment additions has steadily increased . partially offsetting these higher costs is reduced insurance expense for 2015 resulting from favorable claims experience . the net result is still an adverse impact on operating earnings and management is working to reverse this situation . the demand problem is being addressed with increased marketing efforts . the cost problem is being addressed through sales of older inefficient equipment , a revamp of the approach to equipment maintenance and certain personnel layoffs that occurred in january 2016 . 20 equipment additions and retirement for the transportation fleet were as follows : replace_table_token_14_th the sale of retired equipment produced gains of $ 16,000 and $ 432,000 in 2015 and 2014 , respectively . the company 's predominate customers are the domestic petrochemical industry . contributing to customer demand is low natural gas prices ( a basic feedstock cost for the petrochemical industry ) and high export demand for petrochemicals . lower natural gas prices beginning in 2011 stimulated and provided an opportunity for increased profitability and this was evident in 2011 and 2012 results . however , increased operating expenses and an industry wide shortage of qualified drivers affected the company by suppressing revenues and results of operations during the heavy demand cycle of 2014 and early 2015. more recently , the united states economy appears to have weakened with demand slackening . in addition , the recent strengthening of the u.s. dollar relative to foreign currency may weaken demand for u.s. sourced petrochemical products . as transportation revenues increase or decrease , operating earnings will typically increase or decrease at an accelerated rate . this occurs because the fixed cost components of the company 's operation do not vary with changing revenues . as currently configured , operating earnings achieve break-even levels when annual revenues average approximately $ 60 million . above that level , operating earnings will grow and below that level , losses result . - oil and gas oil and gas segment revenues and operating earnings are primarily a function of crude oil and natural gas production volumes and prices . comparative amounts for revenues , operating earnings and selected expenses were as follows ( in thousands ) : replace_table_token_15_th ( 1 ) represents the percentage increase ( decrease ) from the prior year . ( 2 ) includes gains from property sales of $ 2.5 million in 2014 . 21 as shown in the table below , declining crude oil , natural gas and natural gas liquid prices coupled with declining volumes acted to reduce revenues and earnings for the comparative years presented . the sales volume decrease followed normal production declines as persistently low prices curtailed the development of natural gas properties in 2013 and 2014 and curtailed crude oil properties in 2015. contributing to operating losses were property impairments as shown above . property impairments resulted in 2015 and 2014 following fourth quarter declines in crude oil prices while impairments in 2013 followed adverse drilling results . comparative volumes and prices were as follows : replace_table_token_16_th during 2015 , the company participated in the drilling of 14 wells with one dry hole . no wells were in process as of december 31 , 2015 and no drilling is currently planned for 2016. an independent

as the skill and judgment of petroleum engineers in interpreting such data . the process of estimating reserves requires frequent revision ( usually on an annual basis ) as additional information becomes available . calculations of estimated future oil and natural gas revenues are also based on estimates of the timing of oil and natural gas production , and there are no assurances that the actual timing of production will conform to or approximate such estimates . also , certain assumptions must be made with respect to pricing . the company 's calculations assume prices will remain constant from the date of the engineer 's estimates , except for changes reflected under natural gas sales contracts . there can be no assurance that actual future prices will not vary as industry conditions , governmental regulation , political conditions , economic conditions , weather conditions , market uncertainty , and other factors , impact the market price for oil and natural gas . the company follows the successful efforts method of accounting , so only costs ( including development dry hole costs ) associated with producing oil and natural gas wells are capitalized . estimated oil and natural gas reserve quantities are the basis for the rate of amortization under the company 's units of production method for depreciating , depleting and amortizing oil and natural gas properties
