Material Balance an overview | ScienceDirect Topics

11.3 MATERIAL BALANCE. Material balance treats a reservoir like a tank, with areal and depth pressure equilibrium. For undersaturated oil reservoirs (i.e., those for which the pressure remains above the bubble point), oil is produced by the expansion of the liquid phases and connate water, the shrinkage of the pore volume, and the influx of

Chapter 4 MATERIAL BALANCES AND APPLICATIONS

A material balance is an accounting for material. Thus, material balances are often compared to the balancing of current accounts. They are used in industry to calculate mass flow rates of different streams entering or leaving chemical or physical processes. 4.2. The General Balance Equation Suppose propane is a component of both the input and output streams of a continuous process unit shown

Mass balance Wikipedia

A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem

Material Balance Analysis Theory fekete

Material balance analysis is an interpretation method used to determine original fluids-in-place (OFIP) based on production and static pressure data. The general material balance equation relates the original oil, gas, and water in the reservoir to production volumes and current pressure conditions / fluid properties. The material balance

Petropedia What is Material Balance Equation

During hot conditions the evaporation of connate water takes place and hence the hydrocarbon content decreases. Material balance methods are used, with the help of static pressure and production data so as to determine the original fluid in place. This material balance is used to calculate the hydrocarbon volume in a reservoir. In simple words

Material balance in waterdrive reservoirs PetroWiki

Example 1: estimating water influx with material balance. Table 1 summarizes the cumulative oil and gas production as a function of time and average reservoir pressure for a black-oil reservoir. The discovery (initial) pressure is 1,640 psia, and production data

Material Balance for a Bottom-Water-Drive Gas Reservoir

Abstract. A material balance is developed for a gas reservoir in which the rising gas/water contact remains horizontal. The time-integrated cumulative water influx is introduced, which for numerical computations is sometimes more advantageous than the van Everdingen and Hurst integral.

MBAL petex

The streamlines tool is to be used when the Material balance and numerical simulation approaches are not adequate (i.e. MBAL will need history, and numerical simulations are computationally expensive when considering multiple producer injector patterns) and a fast way of finding breakthrough and water-cut profiles is required.

Water Balance | A Level Geography

The water balance affects how much water is stored in a system. The general water balance in the UK shows seasonal patterns. In wet seasons precipitation is greater than evapotranspiration which creates a water surplus. Ground stores fill with water which results in increased surface runoff, higher discharge and higher river levels. This means

Pressure and PVT Uncertainty in Material-Balance

Material balance is a simple and one of the most important reservoir engineering tools. Calculations require production/pressure data, PVT data, and aquifer parameters, so that original oil in place and drive mechanisms can be quantified. Data quality is an important issue in material balance calculations. Uncertainty due to data errors can be

Material Balance Equation an overview | ScienceDirect

The material balance equation is directly linked to original gas in place. In order to consider production of an unconventional gas reservoir, a sufficient amount of gas in place within the reservoir is a concern. For shale, this usually means it is a hydrocarbon source that generated large volumes of either thermal or biogenic gas. To have
