Volumetric Methods Volumetric methods are used when subsurface geologic data are sufficient for structural and isopachous mapping of the objective field or reservoir. One of the objectives of this mapping is to estimate oil and gas initially in place. The fraction of oil and gas initially in place ...

• the maturity of a property, • the general methods used to estimate reserves for the property • the range of uncertainty in the reserve estimate. Methods to estimate reserves are categorized here as: • analogy/statistical (identified by Arps as the "barrels-per-acre period," or Period I)...

Methods of Estimating Reserves [align=center] http://fanarco.net/images/reservoir/reserve_images/5.JPG [/align] Methods of estimating reserves may be classified as deterministic (i.e., calculating a single "best" estimate) or probabilistic (i.e., calculating a range of estimates reflectin...

Undeveloped Undeveloped reserves are expected to be recovered (1) from new wells on undrilled acreage, (2) by deepening existing wells to a different reservoir, or (3) where a relatively large expenditure is required to (a) recomplete an existing well or (b) install production or transportation fac...

I will be back soon to continue this thread..
FANARCO, I noticed that some of my figures was deleted, can you upload it again ??

Power sections (which are actually pumping sections for downhole pumps) are supplied unthreaded by the subvendors, for subsequent completion by the "string" manufacturer. This commercial practice is part of a tradition, history, and culture in the oil industry dating back many years. PC p...

petrochemical plants, paper mills, utilities, wastewater treatment plants, etc. They require much less space than the complete "string" of downhole mudmotor applications. A surface pump manufacturer supplies a complete pump unit, often mounted on a base plate and coupled to an electric mo...

If such a pump is connected to a generator instead of an electric motor or any other load (e.g., a drill bit), and the rotor FIGURE 1 Typical progressing cavity pump (courtesy Monoflo Pump). is allowed to rotate driven by the differential pressure, the pump essentially becomes a hydraulic motor, per...

THREE MAIN TYPES OF PROGRESSING CAVITY MACHINES: PCPs9 DHPs5 AND DHMs As shown in Figs. 1 and 2, a PC pump basically consists of a hydraulic section (a rotor inside a stator) and a drive frame transmitting the shaft rotation to the hydraulic section by means of a connecting rod. The connection is a...

Another reason for PC pumps' larger size is their low speed, which requires a gear reducer (or a belt drive) between the motor driver and the pump. This can result in added cost. However, the recent advent of variable frequency drives (VFDs) has allowed elimination of gear reducers and, at the same...

PC pumps are excellent self-primers and have good suction characteristics. They are tolerant to entrained air and gases, and produce minimal churning or foaming. Another major feature of these machines is their high tolerance to contamination and abrasion. Often called a "lastresource pump,&qu...

Guys !!!!!! Below is some of PCP information : BENEFITS OF PROGRESSING CAVITY PUMPS From the standpoint of flow and pressure range, PC pumps compete well with any other type of pump design. They can handle pump flows from fractions of gallons per minute to several thousand gallons per minute. Pressu...
