Lower producing rates will permit the maximum amount of free gas in the oil zone to migrate to the gas cap. Therefore gas cap drive reservoirs are rate sensitive, as lower producing rates will usually result in increased recovery. The cumulative production at that point is ultimate recovery and reserves can be estimated as above. At a set value of reservoir pressure, assume the cumulative amount of gas produced, G p. Effect of gas cap size on ultimate oil recovery.

Calculate G p using Equations 5-160 and 5-163. This larger recovery efficiency is also attributed to the fact that no gas saturation is being formed throughout the reservoir at the same time. As the expanding gas cap reaches the producing intervals of upstructure wells, the gas—oil ratio from the affected wells will increase to high values. When an oil well is brought on production at a constant flow rate after a shut-in period, the pressure behavior is essentially controlled by the transient flowing condition. Ultimate oil recovery: Oil recovery by gas cap expansion is actually a frontal drive displacing mechanism which, therefore, yields considerably larger recovery efficiency than that of depletion drive reservoirs.

Drive Reservoir

Conversely, extremely thin oil columns where early breakthrough of the advancing gas cap occurs in producing wells may limit oil recovery to lower figures regardless of the size of the gas cap. Gas-oil ratio: The gas-oil ratio rises continuously in upstructure wells. The simplest model that can be used to estimate the water influx into a gas or oil reservoir is based on the basic definition of compressibility. .

Hence, a strong influence by aquifer may be the most potent primary drive mechanism available in comparison to the others. As a result of creating a mobile gas phase in the oil zone, the following two events will occur: 1 the effective permeability to oil will be decreased as a result of the increased gas saturation; 2 the effective permeability to gas will be increased, thereby increasing the flow of gas.

Ultimate oil recovery : Oil recovery by gas cap expansion is actually a frontal drive displacing mechanism, which, therefore, yields considerably larger recovery efficiency than that of depletion drive reservoirs. Calculate N p by Equation 5-159. Compare the calculated G p with the assumed G p from Step 1. Lower producing rates will permit the maximum amount of free gas in the oil zone to migrate to the gas cap. Reservoir pressure remains high, and gas—oil ratio remains low during production. Aquifer volume is quite large in comparison to reservoir volume, 10 times or larger than the reservoir. It is suggested that if during any long period the production rate and reservoir pressure remain reasonably constant, the reservoir voidage rate must be equal to the water influx rate.

Iqbal, in , 2016 Role of material balance analysis in reservoir characterization Reservoir drive mechanisms can be identified by the material balance method by various plotting techniques described earlier. The degree of pressure maintenance depends upon the volume of gas in the gas cap compared to the oil volume. If the gas saturation exceeds the critical gas saturation, the evolved gas begins to flow in the oil zone. Compare the calculated G p with the assumed G p from Step 1.

When the gas cap is considered the main driving mechanism, its size is a measure of the reservoir energy available to produce the crude oil system. Gas cap drive reservoirs can be identified by the presence of a gas cap with little or no water drive as shown in Figure 4. These characteristic trends are summarized below: Reservoir pressure: The reservoir pressure falls slowly and continuously. The problem is that once you have gotten your nifty new product, the singer sewing machine manual gets a brief glance, maybe a once over, but it often tends to get discarded or lost with the original packaging. At a set value of reservoir pressure, assume the cumulative amount of gas produced, G p. This larger recovery efficiency is also attributed to the fact that no gas saturation is being formed throughout the reservoir at the same time. Water production: Absent or negligible water production.

When the gas cap is considered the main driving mechanism, its size is a measure of the reservoir energy available to produce the crude oil system. The primary difference between the Carter and Tracy technique and the van Everdingen and Hurst technique is that Carter and Tracy technique assumes constant water influx rates over each finite time interval. In fact, an efficiently operated gas cap drive reservoir must also have an efficient gravity segregation drive. If the assumed and calculated G p values agree, return to Step 1 and set a new pressure. Such recovery normally will be 20—40% of the original oil-in-place, but if some other features are present to assist, such as steep angle of dip, which allows good oil drainage to the bottom of the structure, considerably higher recoveries up to 60% or greater may be obtained.

If the gas saturation exceeds the critical gas saturation, the evolved gas begins to flow in the oil zone. Therefore, in order to achieve maximum benefit from a gas cap drive-producing mechanism, gas saturation in the oil zone must be kept to an absolute minimum.

Pressure tends to be maintained at a higher level than in a depletion drive reservoir. Calculate S o using Equation 5.

If the assumed and calculated values do not agree to a satisfactory degree, repeat the calculations from Step 1 for another value of G p. Such recovery normally will be 20% to 40% of the original oil-in-place, but if some other features are present to assist, such as steep angle of dip which allows good oil drainage to the bottom of the structure, considerably higher recoveries up to 60% or greater maybe obtained. Early water production is encountered at the downdip wells, and water production increases with time. Sanyo Model Dp19647 Manual File Name: Sanyo Model Dp19647 Manual.

The original pressure establishes values for B oi, B gi, and R si, and the pressure at the given level of depletion establishes values of B o, B g, and R s. It is found that the Carter and Tracy water influx model does not require superposition and allows direct calculation of water influx. Under favorable conditions, oil recovery efficiency under aquifer water drive could be as much as 50% or more.
