Assessment of Petroleum Properties
This class teaches the methods and processes for assessment and evaluation of taxable values of petroleum properties.
- Production methods: primary recovery, enhanced recovery (waterflooding, thermal, miscible, polymer, surfactant, CO2)
- Estimation of reserves and future production: (a) definition of reserves - SPE, WPC, SPEE 468; (b) methods- analogy, volumetric, material balance, performance or decline curves, simulation, types of curves - hyperbolic, exponential, harmonic, WOR, GOR; (c) forecasting production
- General appraisal methods and assessment under proposition 13: (a) three approaches to value - sales, cost and income; (b) proposition 13, R&T code section 51, property tax rules 2,4,8,121, 122,5, 124, 468; (c) supplemental assessments: new discoveries; new construction - additions & deletions
- Petroleum property appraisal methods: (a) forecasting oil & gas production; (b) cashflow components & analysis, such as revenues - product prices; expenses - fixed & variable and what is allowed under rule 8; abandonment & environmental; real vs nominal dollar; working, net revenue, royalty interests; risking and discounting. (c) deriving discount rates, such as sales data, WACC or band of investment, and market surveys; (d) income multipliers / measures of success: payout, $ per daily bbl, profit to investment and $ per bbl of reserve
- Appraisal of wells and equipment: wells, production equipment & surface facilities, idle or surplus equipment
- Taxable value - market vs factored base year values
This course is for anyone that would like to expand their knowledge and skill-set in estimating oil and gas property value.
