TimeVisuals and Notes (description of visuals used, props used, etc.)IntroductionIntroduction (Warm up, Motivation/WIIFM, Objectives, Route, Instructor intro and credibility, Transition)3 Min for Intro.Attention/Warm-up In 2015, 172,882,767 barrels of oil were reported as production to the Office of Natural Resources Revenue – a.k.a., ONRR – from federally owned minerals. This equated to approximately $ 11,798,913,584.24 in revenue from royalties So, why is it important to accurately calculate the barrels of oil an operator reports to Office of Natural Resources Revenue (a.k.a., ONRR) on their Oil and Gas Operations Reports (a.k.a.,OGORs)?Anticipated responses (Pass out miniature candy bars to those who answer):They pay money back to the federal government for each barrel of oilThe oil from federal reserves belongs to the American people.Introduction to topic and Instructor (Credibility)Good morning/afternoon. My name is Student 2. I work in the Pinedale, Wyoming BLM Field Office and am a Production Accountability Technician. Prior to joining the BLM in this position five years ago, I was the Vice President of Finance and Human Resources for White Mountain Operating – an oil and gas drilling company located in Pinedale. So, I’ve been around the industry for over ten years.Hook (WIIFM)The operators pay “royalties”, in other words, money, back to the US federal government for the oil they extract from federal mineral reserves. These royalties are paid because this oil belongs to all the American people. That means you (point), and you (point to someone else) and you (point to another person). This revenue stream collected go into the federal budget to the benefit all of us (sweeping arm gesture around the room). So, you can see why it is important to all of us to verify the accuracy of the volumes of oil that are reported and on which royalties are paid.Our Objective is: Given an oil run ticket, tank table, API Standards Petroleum Measurement Tables 5A and 6A, Oil Volume Calculation Form and OGORs, calculate oil volumes and compare/verify the results to the information reported in the OGORs.Now that you know what our objective is let’s take a look at what we will be covering to get you to that objective.RouteFirst, we are going to discuss how raw data for oil volumes is collected. Next, we will review the necessary formulas and handouts required to calculate oil volumes.Finally, we will learn how to calculate, and correct volumes of oil to compare to the operators’ reported volumes on their OGORs.TransitionYou now know who I am and what we will be covering, so let’s begin calculating and comparing some oil volumes! So let’s get to it!Est. TimeVisuals and Notes (Description of visuals used, props used, etc.)BodyPresentation content, Delivery strategies, Exercises/practice, Assessments3 Min MP1: How oil is measuredPP Slide truck sales animationHold up hydrometer and gauge lineTransition:So, how does the operator know how much oil they are producing or selling?One way is to sell by truck. (Show PPT graphic – explain – the truck pulls up on site. Using a hydrometer, the driver samples the oil to determine gravity and sediment and water and measures the depth of oil in the tank so he has a starting volume of oil. Then, he hooks up the truck and begins transferring oil. After he has pulled the oil, the depth of the tank gets measured again to determine how much oil he removed. The difference in the amounts provides the “raw” volume data.A characteristic of all liquids is that they expand and contract with changes in temperature. For example, 1,000 barrels of 39? API gravity crude oil at 80? Fahrenheit occupies about 1% (10 barrels) more volume than at 60? Fahrenheit. So, in order to calculate oil volumes and compare them to the volumes reported to ONRR on their (OGORs), we’ll have to make a few calculations and adjustments to bring standardize the API Gravity and Temperature. 10 Min MP2: How to correct the “raw” volumes to adjust for temperature, gravity and S&W.Distribute-handouts to studentsTo that note, we will first calculate the raw data from the run tickets using their corresponding tank strapping tables. Then, using the provided that volume has to be converted to a standard temperature and specific gravity and corrected for percentage of BS&W (sediment and water). Yep. More math. Once this net volume has been determined, you will compare the total to what the operator reported on their OGORs. Find your handouts labeled “Exercise 1”. Let’s do this exercise together.MP2: ContinuedHave the areas highlighted on the handouts.Demonstrate during presentation and conduct the each step with the students.Will flip back and forth through these slides as appropriate during the exercise.PP Slide Run ticket with areas highlightedPP Slide Tank Table with rows highlightedPP Slide with rows highlighted for table 5aPP Slide with rows highlighted for table 6aPP Slide with animation to walk through the oil volume calculation sheetPP Slide with OGOR volumesOn the paper labeled “Run Ticket #1”, locate the opening gauge, opening temperature, closing gauge, closing temperature, observed gravity, observed temperature and S&W.You’ll notice the gauges on the run ticket are in feet, inches and quarter inches. On the tank table labeled “A”, looking across the top, locate the feet which match the opening gauge feet on the tank table. View down the column until you are equal to the inches and quarter inches declared as the opening gauge inches and quarter inches. Note the barrels of oil at that intersection on your oil volume calculation sheet.Now, do the same for the closing volume feet, inches and quarter inches on the run ticket.From the run ticket, enter the open and closed gauge temperature, observed gravity, observed temperature and S&W on the “Tank Gauge Calculation Worksheet” as shown on this PowerPoint. To determine the correction factor needed for the calculations, find the copies of the 5a and 6a “Petroleum Measurement Tables” in your handouts.Table 5a will give us our true API gravity. Look across the top and find the “Observed Gravity” as shown on the run ticket. Now, look down the left column and find your “Observed Temperature”. Write in the “True API Gravity” spot on your oil calculation worksheet, the number rounded to the nearest whole number, where the column and row intersect.Table 6a will give us our correction factor to use in the calculation. Across the top of table 6a, locate the number for the “True API Gravity” you just found in table 5a. Look down the left column and find your “Opening Volume Temperature” from your run ticket. Note in the correction factor, where the column and row intersect on the table, on your oil volume calculation sheet in the cell on the first row in the Corr. Factor columns.Continued from above Do the same for your “Closing Gauge”, only place the correction factor on your oil volume calculation sheet in the cell on the second row in the Corr. Factor columns. The next step on your oil volume calculation worksheet is to multiple the opening gauge barrels (first row in the table) by the Correction Factor. Write the answer in the “Volume (BBLS)” cell for that row.Do the same for the closing volume.Subtract the opening gauge “Volume (BBLS)” from the close gauge “Volume (BBLS)” to get the “Total Gross Barrels” and note that number.Finally, we need to find the “S&W Factor” used to determine the “Net Standard Barrels.”Earlier, you noted the percent “BS&W” from your run ticket on your worksheet. To determine the “S&W Factor”, multiple the percent BS&W from the run ticket by .01.Multiple that value by the “Total Gross Barrels” on the worksheet. Write that number in the S&W Barrels cell.Subtract the value in the “S&W Barrels” cell from the “Total Gross Barrels” number. This gives you the “Net Standard Barrels”.Look at your OGOR B for this exercise. The rounded number of “Net Standard Barrels” from your worksheet should match the volume reflected next to disposition code 10. These volumes should match.Do you have any questions about this exercise before you tackle one on your own?Anticipated questions – could be some about the math steps.10 Min Leave PowerPoint slide up showing the completed Oil Volume Calculation Sheet from Exercise #1It is now your turn to calculate and correct volumes of oil using Exercise #2. Feel free to work together and I’ll be walking around if you have any questions.2 Min PP Slide Exercise#2 Oil Volume Calculation Worksheet with answers Transition:Let’s check your results. Did anyone calculate “Net Standard Barrels” that differed from the volume reflected on OGOR B Disposition 10? What might have caused the calculations to not match?Anticipated answers:Mathematical errorsOperator reported the wrong amount on their OGORsGreat job on the exercises! You are all “Rock Stars”. Pass out the rest of the candy. Let’s now wrap things up.Est. TimeVisuals and Notes (description of visuals used, props used, etc.)Conclusion(Review, Assess, Transfer) 2 MinConclusion:Objective (Re-Stated)As you recall, our objective was for you to be able to given an oil run ticket, tank table, API Standards Tables 5A and 6A, Oil Volume Calculation Form and OGORs, calculate oil volumes and compare/verify the results to the information reported in the OGORsSummaryIn order to get you to that objective, we first identified the required information on the run ticket.Next, we calculated the opening and closing volumes from information found on the tank tables.Then, using Tables 5a and 6a from the “Petroleum Measurement Tables” and our “Oil Volume Calculation” worksheets, determined the “Net Standard Barrels of oil. Finally, we compared our worksheet results to the volumes the operator reported to ONRR on their OGORs.Transfer (What can the student now do?)You are now ready to use your skills to ensure the operator has reported their oil volumes correctly.Close (Tie to Attention Step)And why is this important? (Their answer should tie to royalties.)BINGO! It’s about the money!Thank you for your attention and participation. ................
