Petroleum in Basement Rocks. The Properties of Petroleum Fluids. Reserves status categories define the development and producing status of wells handbbook reservoirs. J Can Pet Technol 24 4.
Some cherts exhibit dual porosity and have significant storage capacity in the matrix but that contributes little to reserves. Additional oil and gas expected to be obtained through the application of fluid injection or other improved recovery techniques for supplementing the natural forces and mechanisms of primary recovery should be included as “proved developed reserves” only after testing by a pilot project or after the operation of an installed program has confirmed through production response that increased recovery will be achieved.
It will be another 5 months until I get to test it on the road.
SEC in  stated that “there is no mitigating modifier for the word certainty. SEC definitions handbolk use “reasonable certainty” to describe the controlling condition for proved reserves, but neither offers quantification of the term. Jul 17, Oddometer: Fundamentals of Reservoir Engineering. The graphics module then can be used to compute a production forecast, given initial and final production rates, using any of the curve types exponential, hyperbolic, or harmonic that typically are programmed into the software.
Frequently, pumpers or lease foremen maintain records of well tests, pressures, and equipment changes in “daily gauge reports” that generally are not available elsewhere. Free ADV gear for annual subscribers: J Pet Technol 12 3: One should be alert to all circumstances in which reservoir extent may be limited by faulting, permeability changes, depositional discontinuities, or any other condition that might interrupt fluid flow. N p can be extrapolated to a local average ” f o cutoff,” but this cutoff might be too low for wells with low productivity.
Wedging in the handbookk area on the northwest side reflects truncation of HKO by the fault. Accordingly, such costs include labor only if shutting in the well or facility would save that cost. Hqndbook certain instances, proved reserves may be assigned to reservoirs on the basis of a combination of electrical and other type logs and core analyses which indicate the reservoirs are analogous to similar reservoirs in the same field which are producing or have demonstrated the ability to produce on a formation test.

The term 2P is a cumulative expression for the sum of proved and probable reserves; the term 3P embraces the sum of proved, probable, and possible reserves. In theory, vertical interference testing or vertical pulse testing can determine this parameter, as discussed by Earlougher,  but the test procedure involves two sets of perforations separated by a packer, an expense operators might be reluctant to incur. The Pitfalls section of this chapter discusses some factors affecting production forecast reliability.
State and federal income tax and corporate overhead usually are excluded from out-of-pocket costs.
Estimates of proved reserves do haandbook include the following: The method of estimation is called probabilistic [our emphasis] when the known geological, engineering, and economic data are used to generate a range of estimates and their associated probabilities. Although volumetric methods are the most widely used methods for estimating reserves, results from their use might be subject to considerable uncertainty, depending on the geologic setting and the amount and quality of geologic and engineering data.
In this context, the term “proved” refers to the actual quantities of petroleum reserves and not just the productivity of the well or reservoir. If such a well is in the transient stage, apparent b factors from curve fitting might not represent of the semisteady-state stage.

SPE Res Eng 11 handook Ok, this is not technically for the GS, but it is gonna result in more GS mileage this winter. Most laboratory compressibility data are measured using hydrostatic stress, which can be related to reservoir stress by Computer simulation that is used before production initiation is considered a static method. Behind-pipe reserves are expected to be recovered from zones in existing wells that will require additional completion work or future recompletion prior to the start of production.
During pressure reduction of reservoir fluids, the resultant stresses on reservoir rocks differ from those on core samples during hydrostatic testing in the laboratory. Your email or ADVrider name: Lacking such support, however, the projection should be confirmed through volumetric means before booking the forecast volumes as proved reserves.
Historically, production projections based on such analyses have been classified as proved reserves.
Sooo…what did Santa Bring Your GS?
Water Drive Gas Reservoirs: SEC engineering staff modified its application and interpretation of those definitions in light of the widespread technological advances in over the previous 20 years. Incremental probable P2 reservoir volumes typically are the result of subtracting P1 volumes from the isopach of 2P volumes.
This interpretation is supported by regional studies and the 2D seismic lines indicated on the net sand isopach. An alternative to isoultimate hansbook maps is the use of “bubble maps,” in which the size of the circle drawn around a wellbore is proportional to the parameter or measurement being compared.
