Definitions
- the present invention relates to the field of the determination of geological representations, and in particular the field of the determination of hydrocarbon reservoir representations under constraints.
- a well test can provide a better understanding of the characteristics of the reservoir in which hydrocarbons are trapped. Most often, a well test includes the opening (phase called “draw down” in English) and / or the closure (so-called phase "build up” in English) of the well considered: variations in flow and pressure in time are then recorded.
- One of the objectives of a well test may be to determine the capacity of the reservoir for the production of hydrocarbons, such as oil or natural gas.
- Another objective of such a test may be descriptive, i.e. to determine the geometries and certain characteristics of the reservoir (i.e. rock permeability, presence of boundaries, connectivity of wells between them, etc.).
- this approach can be complex in particular to verify certain dynamic constraints such as "non-connectivity" between two wells because the combinatorics can be too heavy.
- the present invention thus improves the situation.
- the present invention proposes to improve the facies group determination in the geological model by taking into account in particular certain dynamic constraints a priori by proposing an iterative method of determination. facies groups while avoiding "back-backs".
- the present invention thus provides a method of determining geological facies groups among facies of a first set of facies groups and a second set of facies group in a meshed geological model.
- the geological model includes at least:
- the links of the set of connected links are associated with a group of facies among the first facies group set.
- Each cell of the model is associated with a local proportion value for each facies of the first set of facies groups and the second set of facies groups;
- the method comprises:
- said first facies group is a facies group among the first facies group set, for each current virgin mesh adjacent to the connected mesh set, determining a second facies group among facies groups of the first facies group a set of facies groups and the second set of facies groups according to the local proportion values of the facies groups for said current virgin mesh and if the second determined facies group corresponds to the first facies group, identifying said current virgin mesh as a candidate mesh;
- first facies group is a facies group among the second facies group set, for each current adjacent viral mesh associated with a facies group, determining a second group of facies among facies groups of the first set of facies groups and the second set of facies groups as a function of the local proportion values of the facies groups for said current virgin mesh and if the second facies group determined corresponds to the first facies group, identifying said current virgin mesh as a candidate mesh;
- a group of facies may include one or more facies. This group of facies can also be a function of architectural elements or sedimentary body. Each facies group may correspond to sedimentation patterns. These groups are most often determined by geologists upstream of the process described above and can be an input of the latter.
- the first facies group set may include facies groups having a common feature such as good connectivity (i.e. permeability). This first set can be empty.
- the second set of facies group may include facies groups of the model not being in the first set. This second set can also be empty.
- the denomination "virgin mesh” is arbitrary. Any other denomination is also possible.
- the stitches are the stitches not yet definitively associated with a group of facies.
- the denomination "connected mesh” is arbitrary. Any other denomination is also possible.
- the connected meshes can be the meshes associated definitively with a group of facies considered by a geologist as “connectable” (i.e. allowing a connection or a communication) because of their intrinsic permeability.
- the connected meshes are the meshes associated with a group of facies of said first set.
- the model may include other mesh sets as an "unconnected" mesh set. This set can group the meshes not present in one of the preceding sets and / or meshes permanently associated with a facies group considered by a geologist as not "connectable”.
- the determination of a first group of facies can be done stochastically according to the overall proportions of facies in the model.
- the overall proportions can be an average over all the meshes of the local proportions of the facies (resulting for example from cubes of proportion received).
- a current virgin mesh "neighbor" of another mesh is for example a virgin mesh sharing an edge, a face or a point with this other mesh.
- the "identification of a common virgin mesh as a candidate mesh” may include adding this blank mesh to a possible candidate list, adding a flag (or "flag” in English) to this blank in order to facilitate its future identification, the name change of the mesh, or any other similar method.
- the method may furthermore comprise:
- the first facies group is a group of facies among the first set of facies groups, reiterating steps / a / to Here of the method by adding the selected virgin mesh to the set of connected meshes and removing the virgin mesh selected in the set of blank stitches; the / otherwise, reiteration of the steps lai to Here of the process by removing the virgin mesh selected in the set of virgin meshes.
- the first set includes facies groups that have been previously identified by an operator (eg a geologist). This identification may include the appreciation of the connectable (or non-connectable) nature of the facies as described above.
- each mesh of the model may be associated with a mesh volume, the method may furthermore comprise:
- the target volume value may be a value set by an operator but may also be determined using stochastic printing in a probability distribution of a target volume.
- Each mesh of the model may be associated with a mesh volume, the method may furthermore comprise:
- the predetermined distance is the investigation distance and the reference mesh is a mesh of the well in the model.
- the method may furthermore comprise:
- This deletion can make it possible to isolate the determined connectable volume (ie formed by the connectable meshes) and to avoid that a subsequent simulation increases it by connecting new connectable links to the already determined connectable volume.
- selecting the virgin mesh from the candidate mesh may include:
- the selected virgin mesh being the mesh associated with the smallest variogram deviation among the variogram deviations determined.
- the target variogram may be a variogram along the vertical or z axis of the model.
- This variogram can also be a variogram along several axes of the model like the x and y axes.
- the variogram calculated for a given candidate mesh is the variogram of meshes having a group of associated facies, while considering temporarily, that the candidate mesh is associated with the first group of determined facies.
- This variogram may not take into account blank meshes.
- the model may furthermore comprise at least one target distribution of distances in at least one direction in said model between two meshes of said model, the selection of the virgin mesh among the candidate meshes may comprise:
- the selected virgin mesh may be the mesh associated with a distribution gap the lowest among the distribution differences determined.
- the distance in one direction between two meshes is the length of the projection of the segment whose ends are these two meshes in this direction.
- the distance along two (non-parallel) directions between two meshes is the length of the projection of the segment whose ends are these two meshes on the plane formed by these two directions.
- the distance in three directions (then forming a three-dimensional landmark) between two meshes is a distance between these two points in the 3D space.
- the distance can be a Euclidean distance or any other distance in the mathematical sense.
- the distribution gap associated with said current candidate mesh may comprise a normalization of the calculated distribution and the target distribution by dividing these distributions by the number of distances that made it possible to construct them, in order to allow an adequate comparison.
- the present invention is also directed to a device for determining groups of geological facies among a set of facies groups in a meshed geological model.
- the geological model includes at least:
- Each cell of the model being associated with a local proportion value for each facies in the facies group set the device comprises:
- a computer program, implementing all or part of the method described above, installed on a pre-existing equipment, is in itself advantageous, since it allows a group of facies determination in a geological model.
- the present invention also provides a computer program comprising instructions for implementing the method described above, when this program is executed by a processor.

- the present description can be generalized to a situation in which the model is in three dimensions.
- the model 100 comprises a set of mesh 101 called "connected mesh". Each cell of this set is associated with a group of facies (ie GFi or GF 2 ) considered to have good connectivity: for example, these groups of facies may comprise porous and / or permeable rocks (eg sands).

- facies groups may also have poor connectivity in a particular embodiment.
- the remaining meshes of the model 100 are the meshes that are not associated with a group of facies (like the mesh 103) and are called "virgin meshes".
- the mesh 104 has the particularity of representing the position of a well in the geological model considered: this mesh is also called "reference mesh”.
- These meshes are the meshes of the set of virgin meshes and having at least one edge (respectively, face for a 3D model) common with a mesh of the set of meshes 101. It is also possible, in another embodiment, to define that these stitches are the stitches of the set of blank stitches and having at least one common point (or angle) with a stitch of the set of stitches 101.
- the first group of facies see Figures 2a to 2d below for the draw of this first group
- the meshes In this embodiment, adjacent virgins are the stitches 1 10 to 1 16.
- Figure 2a illustrates a random draw of a first group of facies in a embodiment according to the invention and with overall target proportions of facies in the model.
- the overall target proportions of the model of different facies groups can be calculated, for example, from model proportion cubes.
- Each proportion cube is associated with a facies group and represents the proportions of that group for each mesh of the model (ie, local proportion values).
- the proportion cubes normally lie at 1 for a grid of coordinates (i, j) of the model (respectively (i, j, k) in 3D).
- FIG. 2b illustrates a random draw of facies groups in an embodiment according to the invention and thanks to local target proportions of facies for the mesh 1 10 of FIG. 1.
- the local proportion values of the mesh 1 10 can be determined using the proportion cubes associated with the model 100.

- FIG. 2c illustrates a draw of facies groups in an embodiment according to the invention and thanks to local target proportions of facies for the mesh 1 1 1 of FIG. 1.
- the local proportion values of the 1 1 1 mesh can be determined using the proportion cubes associated with the model 100.
- the exclusion distance may be a function of the target variogram of the model: for example, the exclusion distance may be one or two times the range of the variogram.
- the local proportion value of the facies group 1 for the 1 1 1 mesh is Pl_i_ii i and the local proportion value of the facies 2 group is PL 2 _m, it is possible to represent the local proportion values according to the stacked diagram. of Figure 2b.

- the local proportion value of the facies group 1 for the 1 12 mesh is Li 1 12 and the local proportion value of the facies 2 group is PL 2 _n 2 , it is possible to represent the local proportion values according to the diagram. stacked in Figure 2b.
- Figure 3a illustrates the identification of candidate meshes in a 2D geological model and in one embodiment of the invention.
- the facies group selected according to the global proportion values is GF 2 (see Figure 2a);
- the group of facies selected according to the local proportion values for the mesh 1 is GFi (see FIG. 2b);
- the group of facies selected according to the local proportion values for the cells 1 1 1 1 to 1 14 is GF 2 (see FIGS. 2c and 2d for the cells 1 1 1 and 1 12);
- the group of facies selected according to the local proportion values for the mesh 1 is GF 3 ;
- the group of facies selected according to the local proportion values for the mesh 1 16 is GF 2 .
- the other adjacent virgin meshes i.e. 1 1 1 to 1 14 and 1 16 are then identified as candidate meshes.
- Figure 3b illustrates the assignment of a facies group to a mesh in a geological model and in one embodiment of the invention.
- the cells 11 to 14 and 16 are candidate meshes and GF 2 is the group of facies selected as a function of the global proportion values.
- This selection may, for example, be stochastic (eg random draw equiprobable for each candidate mesh).
- this mesh 1 1 1 is then associated with the facies group GF2. In addition, it is possible to add this mesh 1 1 1 to the group of connectable meshes 101. This mesh 1 1 1 then removed from the virgin meshes since a group of facies is associated with it.
- FIG. 4a illustrates a variographic cloud 400 in one embodiment of the invention.
- the variographic cloud 400 (or variographic cloud) is here a cloud of points of the data expressing their variability ⁇ according to their inter-distances h.
- the point 405 of this variographic cloud represents the 405 ⁇ variance of the values of the facies groups of two meshes of the model located at a distance 405h. It is also possible to make this variogram not with two single meshes but with two mesh windows each having a plurality of meshes. Each group of facies can be associated with a numerical value allowing to calculate a variance.
- This difference can be calculated by summing, for example, the absolute value of the differences of the variances for two points of the variograms having the same abscissa: the difference between the point 406 and the point 407 of abscissa i is Ay i .
- the sum can be a simple sum or a weighted sum (with a weight depending on h, for example).
- R is called the "range of the variogram” or “practical scope", ie the distance from which the variogram remains within a 5% interval around its paliery (+ ⁇ ). Of course, in practice this last interval can be set to another value.
- FIG. 5 illustrates a first possible result of the method described in one embodiment of the invention in a three-dimensional model.
- This model 500 is made up of “connectable” meshes like the 501 mesh and “non-connectable” meshes like the 502 mesh.
- FIG. 6a illustrates a theoretical histogram or "target" 600 of distribution of the distances between pairs of meshes in one embodiment of the invention and along one of the axes of the model space (here z).
- the length of a segment (respectively distance between two meshes) along an axis may be the length of a projection (for example, orthogonal) of this segment (respectively distance between the projection of the two points) on this axis.
- the target distribution along an axis is, for each h, L x (L z -h) in a two-dimensional case or L x L y (L z -h) for a three-dimensional case (with L z the length of the rectangle or parallelepiped rectangle along the z axis, L x the length of the rectangle or parallelepiped rectangle along the x axis and L y the length of the parallelepiped rectangle along the y axis).
- a "normalized” theoretical histogram can also be calculated by dividing the values of the theoretical histogram by the sum of its values (ie by the total number of meshes): this standardized theoretical histogram is called "normalized theoretical distribution of the distances between pairs of mesh ".
- FIG. 6b illustrates, for its part, an "experimental" histogram of distribution of the distances between pairs of cells in one embodiment of the invention.
- Such a histogram 601 represents the distribution, in the same connected component, of the distances along the z axis between pairs of meshes having a group of facies associated in the model.
- the segments taken into account in this calculation are the segments of the rectangle 605 (having for example the same dimensions as the rectangle 602) of FIG. 6d and whose two ends are in the connected set 606, each of the cells of this together is associated with a facies group ("connectable” or "non-connectable”).
- the segment 607 is taken into account for the construction of the histogram 601 while the segment 608 is not taken into account for this construction.
- a standard experimental histogram can also be calculated by dividing the values of the experimental histogram 601 by the sum of its values: this standard experimental histogram is referred to as the "standardized experimental distribution of the distances between pairs of meshes".
- This sum can be simple or weighted (for example, depending on the distance h of the two points).
- FIG. 7 illustrates a second possible result of the method described in one embodiment of the invention.
- the model presented in FIG. 7 is derived from a method of determining the facies groups according to an embodiment of the invention seeking to minimize the difference between the experimental normalized histogram and the target normalized histogram.
- the selected mesh of candidate meshes is that which minimizes the difference between the new normalized histogram and the target normalized histogram.
- FIG. 8 illustrates a flowchart in one embodiment of the invention.
- facies groups associated with certain meshes are known or imposed as input constraints. This situation may happen in particular:
- meshes represent areas of the model in which the geological composition is known (eg meshes along a wellbore);
- the method described below uses as “germs” the "connectable” meshes of the model. If these "connectable” links form a plurality of connected components, it is possible to apply the method described below iteratively to each of these connected components.
- the sum may be limited to meshes of which a distance to a reference mesh is less than a predetermined distance.
- this reference mesh can represent a well in the model.
- the distance can then be the investigation distance specific to the well tests performed on the well (or any other distance defined by an operator / geologist).
- a first group of facies is determined (step 804) among all the facies groups of the model as a function of the global proportion values of the facies (eg 70% of sand, 30% clay on average throughout the model). These global proportion values can be determined from the 805 proportion cubes associated with the received model 801.
- the first group of facies is a group of facies not considered connected, it is possible to select the current virgin meshes of meshes associated with a group of facies.
- a second group of facies is determined (step 806) as a function of the local proportion values of the facies groups for said current virgin mesh. If the second group of facies determined corresponds to the first group of facies, it is possible to add the current mesh selected to all the candidate mesh.
- test 807 test NO_MAILL
- step 812 it is also possible to determine, for each candidate cell, the difference between the variogram of the model and a target variogram (step 812) as described with reference to FIGS. 4a to 4c.
- step 814) the best candidate mesh by minimizing an overall difference based on the two previous calculated differences (for example, the overall difference being the simple or weighted sum of the two previous differences) .
- step 816) it is then possible to add the selected virgin mesh to the set of meshes said "connected" if the first group facies is a facies group previously identified by an operator (eg facies groups with good connectivity, permeability).
- this selected candidate mesh is removed from the blank cells since it is associated with a group of facies.
- FIG. 9 represents an example of a device for determining groups of geological facies in one embodiment of the invention.
- the device comprises a computer 900, comprising a memory 905 for storing instructions for implementing the method, the received measurement data, and temporary data for performing the various steps of the method as described above. .
- the computer further comprises a circuit 904.
- This circuit can be, for example:
- processors capable of interpreting instructions in the form of a computer program, or an electronic card whose steps of the method of the invention are described in silicon, or
- a programmable electronic chip such as an FPGA (for "Field Programmable Gate Array”).
- This computer includes an input interface 903 for receiving input geologic models and / or proportion cubes associated with that model, and an output interface 906 for providing geological models completed for eventual submission in Other tools such as flow simulation tools 907.
