Abstract This paper describes the practical applicacion of a method known as Flowing Gas Material Balance FGMB (L. Mattar and Mcneil, 1997) for reserve's estimation using bottomhole flowing pressure data in two dry gas fields in Mexico. The main purpose of this work is to apply the method in real cases having enough data and make a comparison with other standard methods of reserves estimation (J. Lee, 1996 and G.J. DeSorcy, 1994) such as Volumetric, Decline Curve Analysis, Conventional Material Balance and Numerical Simulation to see the results and validate the efficacy of its application. There are some premises should be considered before its application that will be explained, besides the advantages and results of this comparison which showed differences no greater than 10% with respect to the method more trustable to report reserves for these reservoirs.

<div class="WordSection1"><p><em>The purpose of this thesis is to calculate the original oil in place of ENH zone in X field. There are two methods to calculate the original oil in place of ENH zone, which is volumetric method and material balance method. From the calculation of original oil in place of ENH zone using volumetric method is 5.860.310 STB.</em></p><p><em>In Havlena - Odeh straight line material balance method needs the number of water influx. The water influx can be determine using Van-Everdingen Hurst method. The constant number of water influx of ENH zone is 311 BBL/psia. The original oil in place calculation of ENH zone using material balance method is 6.000.000 STB. Decline curve analysis is a method to determine the production performance and estimate ultimate recovery (EUR). By knowing the economic limit rate of ENH zone at 40 BOPD, it can be searched the oil rate and cumulative oil production of ENH zone. The economic limit rate of ENH is reached in March 2019 with recovery factor at 57,95%.</em></p><p><em>Keywords: original oil in place, volumetric, material balance, decline curve analysis</em></p></div>

Original Oil In Place

<p><em>The purpose of calculating the Original Oil In Place (OOIP) is to know the potential of reservoir to be produced. Calculation of OOIP in field Y based on determining the type of drive mechanism at the beginningfollowed by calculation the value of Underground Withdrawal and parameters of fluid expansion. All parameters then used to draw the graphic using Havlena and Odeh Method. The value of OOIP is </em>354,766 MMSTB<em>.</em></p><p><em>Along with the time and production activity, the OOIP will be reduced. Therefore it is important to forecast the production itself. Constant Decline is determined using Trial Error and X<sup>2</sup> Chisquare Test Method with value of constant decline b = 0 and decline rate 0,01855. This means that the type of decline curve is exponential curve. This type of decline curve is used to forecast the production until q economic limit. As a result, the value of Estimated Ultimated Recovery is 296,0386 MMSTB, Recovery Factor 83,4461%, and Remaining Reserve 51,9415 MMSTB</em>.<em></em></p><p align="center"> </p><p>Keyword: <em>Original Oil In Place</em>, <em>Decline Curve Analysis, material balance straight line, Recovery Factor, Remaining Reserve</em></p><p> </p>
