The present disclosure generally relates to systems and methods for correlating gas condensates and wet gases in unconventional shale plays based on an equation of state. More particularly, the present disclosure relates to correlating gas condensates and wet gases in unconventional shale plays based on an equation of state using a condensate gas-ratio, a separator pressure and a separator temperature.
In the absence of pressure, volume and temperature (“PVT”) data, it is almost impossible to generate the data files that are needed to conduct a reservoir engineering analysis and, in particular, a numerical reservoir simulation for modeling fluid behavior in hydrocarbon reservoirs. The typical PVT analysis involves collecting down-hole and/or surface samples, conducting quality control tests and then performing either one of a constant mass expansion (CME) or constant volume depletion (CVD) test to create extended black oil tables needed for the reservoir engineering analysis. Even the most popular oil correlations listed in table 1 below do not work reliably with gas condensates (also referred to as retrograde condensates) and wet gases because the extended black oil correlations are generally prone to errors and inconsistencies.
Therefore, the current trend is to use commercial PVT simulation software to first obtain a mathematically recombined composition, fit the data to an equation of state (EOS) model and create PVT data files for the numerical reservoir simulation in full compositional 7mode. Because this technique can be time consuming and expensive, it is common practice to create reduced compositional models by combining some of the components together and selecting the reduced compositional models that provide a good match with the full compositional models.
The present disclosure is described below with references to the accompanying drawings in which like elements are referenced with like reference numerals, and in which:

In yet another embodiment, the present disclosure includes a non-transitory program carrier device tangibly carrying computer executable instructions for correlating gas condensates and wet gases in unconventional shale plays, the instructions being executable to implement: i) calculating a CGRS value using a reduced pseudo-component fluid model and data for each fluid at multiple data points for a reservoir temperature, a separator temperature and a separator pressure; ii) calculating a CGRA value using the reduced pseudo-component fluid model and data for each fluid at atmospheric conditions; iii) plotting a relationship between the CGRA value and a respective C7+ mole fraction value from the reduced pseudo-component fluid model for each fluid, the relationship representing a CGRA relationship equation; iv) plotting a relationship between the CGRS value and a new parameter X, which is a product of a predetermined scaling parameter W and the CGRA value for each separator pressure for each fluid, the relationship representing a CGRS relationship equation; v) creating a fluid database using a compositional simulation PVT data file for each fluid; vi) calculating a C7+ value using the CGRA relationship equation and one of a known CGRA value for each fluid and a calculated CGRA value for each fluid, wherein C7+ represents the mole fraction of components heavier than heptane (C7); and vii) determining a mole fraction of each pseudo-component in the reduced pseudo-component fluid model using the C7+ value and the fluid database.
The relationship between various quantities of interest, such as the CGRA value and the C7+ mole fraction value can be linear or non-linear. Based on available data, a straight line or polynomial fit can be reasonably made in some cases. However, more advanced methods can be applied to estimate a more complex functional form suggested by the data. Even a non-parametric method of function approximation, such as a neural network, can be applied to establish the relationship. Regardless of the method used to determine the relationship, it must ensure that 1) a fit can be made to the degree of quality appropriate for the task at hand; and 2) the fitted estimator can be evaluated for the input quantity in the desired range. If, for example, the relationship between the CGRA value and the C7+ mole fraction value has been fitted, then evaluation of the fitted estimator for a CGRA value in the desired range yields a mole fraction value for C7+. Various function approximation methods are thus, available and a particular type of function approximation method is not required.
The subject matter of the present disclosure is described with specificity, however, the description itself is not intended to limit the scope of the disclosure. The subject matter thus, might also be embodied in other ways, to include different steps or combinations of steps similar to the ones described herein, in conjunction with other present or future technologies. Moreover, although the term “step” may be used herein to describe different elements of methods employed, the term should not be interpreted as implying any particular order among or between various steps herein disclosed unless otherwise expressly limited by the description to a particular order. While the present disclosure may be applied in the oil and gas industry, it is not limited thereto and may also be applied in other industries to achieve similar results.
Method Description

In step 102, fluid sample data is collected across the unconventional shale play from various wells (the more, the better) to cover a broad range of fluid types to be produced using techniques well known in the art. Each hydrocarbon fluid sample is represented by its own phase envelope and is collected either from the wellbore or at the surface (typically at the separators). A phase envelope is a plot that is characteristic of a hydrocarbon fluid, which is also referred to as a P-T (pressure temperature) diagram in petroleum engineering literature. An example of a P-T diagram is illustrated in
In step 104, the fluid sample data from step 102 is checked for quality using techniques well known in the art and commercially available PVT software for quality control. The fluid sample data that fails to meet predetermined quality control standards may be discarded.
In step 106, an equation-of-state (EOS) model (e.g. the Peng-Robinson or Soave-Redlich-Kwong EOS model) is selected for the fluids represented by the remaining fluid sample data from step 104 using commercially available PVT software.
In step 108, a full model is created using the EOS model selected in step 106 and the commercially available PVT software. This step may involve some initial lumping of heavier components, which usually have smaller mole fractions for wet gases and gas condensates, while honoring available lab data.
In step 110, PVT test data are generated using the full model created in step 108 and commercially available PVT software. The PVT test data may include P-T diagram data, separator test data, CCE data and CVD data.
In step 112, a reduced pseudo-component model is created from the full model generated in step 108 using trial and error techniques and commercially available PVT software. This step is necessary to create a reduced model, which can be used in compositional simulation. The reduced model is a common pseudo-component model in which further lumping is done to reduce the total number of pseudo-components to less than about 10, which reduces the compositional simulation time. Phase behavior calculations and compositional simulations with an equation of state require the use of pseudo-components to represent the oil and gas mixtures. Because of the large number of components which form the heavy fractions (e.g. C6 + fractions), it is necessary to group them into pseudo-components. In other words, the more pseudo-components there are, the longer the simulation will take. Furthermore, to minimize simulation costs, it is also advantageous to lump the light fractions.
In step 114, the reduced model from step 112 is validated using the PVT test data from step 110 and predetermined tolerance criteria to generate various outcomes and commercially available PVT software. If the results of the various outcomes substantially match (i.e. fall within an acceptable margin of error), then the reduced model is validated. Otherwise, step 112 may be repeated to create another reduced model for validation.
In step 116, a CGR value, which is hereinafter referred to as the CGRS value, is calculated using the reduced model from step 114 and commercially available PVT software to run a test for each fluid represented by the fluid sample data at the actual separator conditions (Psep and Tsep).
In step 118, a CGR value, which is hereinafter referred to as the CGRA value, is calculated using the reduced model from step 114 and commercially available PVT software to run a test for each fluid represented by the fluid sample data at atmospheric conditions.
In step 120, a relationship is plotted between the CGRA value calculated in step 118 and a respective C7+ mole fraction value from the reduced model in step 114 for each fluid represented by the fluid sample data by plotting the values using any technique well known in the art, such as the least squares method, and the client interface and/or the video interface described in reference to
In step 122, a relationship is plotted between the CGRS value calculated in step 116 and a respective C7+ mole fraction value from the reduced model in step 114 for each fluid represented by the fluid sample data by plotting the values using any technique well known in the art, such as the least squares method, and the client interface and/or the video interface described in reference to
In step 126, a fluid database is created by generating a compositional simulation PVT data file for each fluid represented by the fluid sample data using the commercially available PVT software that may also be used to run standard tests (e.g. separator test and CME, CVD tests) for producing additional data for the fluid database. Based on the number of fluid test reports received, the fluid database is maintained for each field, which contains but is not limited to PVT data tables in specific numerical simulator input format, the mole fractions of the pseudo-components, saturation pressure (dew point pressure), data on any separator test, and CME, CVD tests, for example. Preferably, a minimum of 5 fluid reports per field is recommended. An exemplary fluid database is illustrated in table 3 below, which includes the mole fraction of seven different pseudo-components (P1-P7), expressed as a percentage, and a C7+% value for each respective fluid.
In step 128, the method 100 determines whether to use the relationship equation from step 122 based on the use of a separator. If the relationship equation from step 122 is not used, then the method 100 proceeds to step 132. If the relationship equation from step 122 is used, then the method 100 proceeds to step 130.
In step 130, C7+ is calculated using the relationship equation from step 122 where C7+ is the mole fraction (in percentage terms) of the components heavier than heptane (C7). For the particular shale play used in
In step 132, C7+ is calculated using the relationship equation from step 120 where C7+ is the mole fraction (in percentage terms) of the components heavier than heptane (C7). For the particular shale play used in
In step 134, the composition (i.e. mole fraction of each pseudo-component) needed to populate the compositional simulation PVT data file is determined using the value for C7+ calculated in step 130 or step 132, the fluid database created in step 126 and the client interface and/or the video interface described in reference to

In step 202, the method 200 determines if hydrocarbon fluid composition data is available. In deep unconventional reservoirs, hydrocarbon fluid composition data is often available for typical fluids in the gas condensate and wet gas ranges. Such data may be equally useful as actual fluid data from fluid samples collected down hole or at the separator. If hydrocarbon fluid composition data is not available, then the method proceeds to step 206. If hydrocarbon fluid composition data is available, then the method proceeds to step 204.
In step 204, fluid sample data is selected from the hydrocarbon fluid composition data that covers wet gases and gas condensates applicable to the particular unconventional shale play using the client interface and/or the video interface described in reference to
In step 206, fluid sample data is collected in the same manner as step 102 in FIG. 1 across the unconventional shale play from various wells to cover a broad range of fluid types to be produced.
In step 208, the fluid sample data from step 204 or step 206 is checked for quality in the same manner as step 104 in
In step 210, an equation-of-state (EOS) model (e.g. the Peng-Robinson or Soave-Redlich-Kwong EOS model) is selected for the fluids represented by the remaining fluid sample data from step 208 using commercially available PVT software.
In step 212, a full model is created using the EOS model selected in step 210 and the commercially available PVT software. This step may involve some initial lumping of heavier components, which usually have smaller mole fractions for wet gases and gas condensates, while honoring available lab data.
In step 214, PVT test data are generated using the full model created in step 212 and commercially available PVT software. The PVT test data may include P-T diagram data, separator test data, CCE data and CVD data.
In step 216, a reduced pseudo-component model is created from the full model generated in step 212 using trial and error techniques and commercially available PVT software. This step is necessary to create a reduced model, which can be used in compositional simulation. The reduced model is a common pseudo-component model in which further lumping is done to reduce the total number of pseudo-components to less than about 10, which reduces the compositional simulation time. Phase behavior calculations and compositional simulations with an equation of state require the use of pseudo-components to represent the oil and gas mixtures. Because of the large number of components which form the heavy fractions (e.g. C7 + fractions), it is necessary to group them into pseudo-components. In other words, the more pseudo-components there are, the longer the simulation will take. Furthermore, to minimize simulation time, it is also advantageous to lump the light fractions.
In step 218, the reduced model from step 216 is validated using the PVT test data from step 214, predetermined tolerance criteria to generate various outcomes and commercially available PVT software. If the results of the various outcomes substantially match (i.e. fall within an acceptable margin of error), then the reduced model is validated. Otherwise, step 216 may be repeated to create another reduced model for validation.
In step 220, a CGR value, which is hereinafter referred to as the CGRS value, is calculated using the reduced model from step 218 and commercially available PVT software to run a test for each fluid represented by the fluid sample data at 3-4 data points for the reservoir temperature, the separator pressure and the separator temperature. In this manner, multiple tests are run for each set of data points compared to step 116 in which only one test is required at the actual reservoir temperature, separator pressure and separator temperature. For example, if 3 reservoir pressures, 4 separator temperatures and 4 separator pressures are used, then the total number of tests to calculate CGRS for each fluid will be 3×4×4=48. Because 3-4 data points are used, this step covers a broad range of reservoir depths, reservoir temperatures, which generally increase linearly with depth, and several possible separator conditions (Psep and Tsep).
In step 222, a CGR value, which is hereinafter referred to as the CGRA value, is calculated using the reduced model from step 218 and commercially available PVT software to run a test for each fluid represented by the fluid sample data at atmospheric conditions.
In step 224, a relationship is plotted between the CGRA value calculated in step 222 and a respective C7+ mole fraction value from the reduced model in step 218 for each fluid represented by the fluid sample data by plotting the values using any technique well known in the art, such as the least squares method, and the client interface and/or the video interface described in reference to
In step 226, a relationship is plotted between the CGRS value calculated in step 220 and a new parameter X, which is the product of a predetermined scaling parameter W and the CGRA value calculated in step 222, for each separator pressure for each fluid represented by the fluid sample data by plotting the values using any technique well known in the art, such as the least squares method, and the client interface and/or the video interface described in reference to
In step 228, a fluid database is created by generating a compositional simulation PVT data file for each fluid represented by the fluid sample data using the commercially available PVT software that may also be used to run standard tests (e.g. separator test and CME, CVD tests) for producing additional data for the fluid database. Based on the number of fluid test reports received, the fluid database is maintained for each field, which contains but is not limited to PVT data tables in specific numerical simulator input format, the mole fractions of the pseudo-components, saturation pressure (dew point pressure), data on any separator test, and CME, CVD tests, for example. Preferably, a minimum of 5 fluid reports per field is recommended. An exemplary fluid database is illustrated in table 5 below, which includes the mole fraction of seven different pseudo-components (P1-P7), expressed as a percentage, and a C7+% value for each respective fluid.
In step 230, the method 200 determines whether to use known values for CGRS, Psep and Tsep based on the use of a separator. If the CGRS value and respective Psep and Tsep values are not known, then the method 200 proceeds to step 233. If the CGRS value and respective Psep and Tsep values are known, then the method 200 proceeds to step 232.
In step 232, the known values for CGRS, Psep and Tsep are stored.
In step 233, the CGRA value from step 222 is stored.
In step 236, the method 200 determines if the Psep value stored in step 232 is substantially close to a Psep value represented by the relationship equation from step 226 using the client interface and/or the video interface described in reference to
indicates data missing or illegible when filed
In step 238, the new parameter X is calculated again using the CGRS value stored in step 232, the A and B values for the closest Psep value represented by the relationship equation from step 226 to the Psep value stored in step 232 and X=(CGRS−B)/A.
In step 240, the new parameter X is calculated again using the CGRS value stored in step 232; A=E/Psep̂F and B=E*Psep̂4+F*Psep̂3+G*Psep̂2+H*Psep+J (wherein Psep is from step 232 and E, F, G, H, J are coefficients); and X=(CGRS−B)/A. The equations for A and B were derived from the curve-fitting data in table 4. The values for E, F, G, H, and J may vary depending on the PVT data for a particular field, however, are E=1.827×104, F=4.7433×10−7, G=−4.5178×10−4, H=0.1903 and J=−20.429 for the particular shale play used in
In step 242, a CGRA value is calculated using the new parameter X calculated in step 238 or step 240, the predetermined scaling parameter W from step 226 and CGRA=X/W.
In step 244, C7+ is calculated using the relationship equation from step 224 where C7+ is the mole fraction (in percentage terms) of the components heavier than heptane (C7). For the particular shale play used in
In step 246, the composition (i.e. mole fraction of each pseudo-component) needed to populate the compositional simulation PVT data file is determined using the value for C7+ calculated in step 244, the fluid database created in step 228 and the client interface and/or the video interface described in reference to
Each method 100 and method 200 involves the use of a common equation of state for all of the fluids and therefore, all data pertaining to the equation of state such as binary interaction coefficients, critical pressure, critical temperature, acentric factor, volume shift parameters will be common for all of the fluids—only the mole fractions will be different for different fluids or samples taken from different parts of the shale play. Because black oil models based on correlations do not work very well for gas condensates and wet gases in unconventional shale plays, and produce erroneous results as far as prediction of gas and oil production for a gas condensate or a wet gas reservoir, the use of either method can produce more accurate correlation results. Moreover, the use of either method only requires the input of three easily accessible parameters (CGRS, Psep. and Tsep.) to generate all of the PVT data required for numerical simulation of the wet gases and gas condensates. In particular, for history matching, either method makes it easy to account for changes in CGR values without having to go through elaborate procedures.
Even if the compositional model generated by either method is not used directly, a black oil model can be generated from it following well known methods. The present disclosure therefore, provides a way to create both compositional and black oil fluid models, given only a limited input, whereas previously established, well known, correlations only provide a way to generate black oil models that often yield inconsistent results for gas condensate or a wet gas reservoirs. These inconsistencies arise because the practitioner often has to mix and match correlations that were developed at different times by different researchers for fluids from different sets of oilfields.
The fluid models generated by either method can be used for reservoir simulation studies as well as for compositional grading studies or for estimating parameters of laboratory settings involving reservoir fluids. When implemented as part of reservoir simulation software, each method provides a quick and easy way to generate fluid models for use in simulation, without requiring expensive, time-consuming fluid analysis, and creating templates for any field. Each method also allows switching from one composition to another quickly, which permits additional flexibility during the history matching phase of compositional simulation. Because each method is based on an equation of state, each method is very robust, fast, efficient and cost-effective.
