Reservoir Simulation with ECLIPSE GRID SECTION

hello my friends in this video I am going to teach you how you can build a simple model in Eclipse and we are going to talk about the courage section in the data file and if you remember from the run space section we are going to build a reservoir which has a 10 accuracy in the x-direction thinkers in the Y direction and teracles in the Z direction we already assigned the number of theories in the Transpac section what we didn't identify what will be the properties of each grid so in the green section we are going to say what will be the dimension of each grid itself and what would be the porosity and permeability after each cell in the our in our model so we need couple and keywords to assign the properties and first keyboard is a hops keyboard what is the Topps keyboard house key music is going to identify the tips of your reservoir so imagine this is a ground surface and you have an underground reservoir like this and taps keyboard is is I didn't find the tips of the reservoir from the ground to the top of the top surface of your reservoir so in our reservoir we have tangles in the X direction tangles in the Y direction so in total we have 100 degrees in the surface of our reservoir so we need to identify what what is the depth of these 100 gates and at the surface of at the top surface of our reservoir so we need to write taps key taps keyboard in in degree section of our data file and we have number of the cells in the top layer which we have 100 cells in the our top surface of our reservoir and the second value 4000 is showing the depths of the reservoir so these steps in our key book in our data file is 4,000 and if you remember from the run spec section we told the data file that we are going to use with field unit so it means that this 4,000 is 4,000 feet so we have the top surface of our reservoir it has 100 key reads and the tips of our reservoir is 4,000 and then we are going to say and what will be the dimension of our guild dimensional each grade in the X Y & Z direction so to identify the dimensional theories we need to use DX dy and DZ keywords so it is the X dy and is it are showing the size of each block each grade block so size of each of these blocks so what you need to do is that you write DX in your data file like this how many queries in total you have we have what at angles in the x-direction Tango's in the Y direction and trickle is in the Z direction so in total we have 10 times 2 10 times 3 so it will be 300 gates in total and the exist showing the what is the X Delta X of each grades so you have total 300 greens and we are saying that the dimension of X in our Delta X in our grades is a 5/5 so wifeís is a dimension of each grades in the x direction so similar to that we need to identify what is the dimension of each carrot in the Y direction which for example in this exact example we say that we have three hundred grit and each dimension is a five weight in the Y Direction similar for the Z direction we have 300 grease and its size in the Z direction is Triffids so we have a Greece which has five five three dimensions don't forget to have a slash in the end of each DX dy and DZ next step is to so till now we identify the dimension of our size of our great vlogs right now we are going to assign permeability and porosity for each of these grades for permeability we are using per mix to identify the permeability in the x-direction my four identify the clarity in the y-direction and perms it to permeability in the z direction how we can write permeability x' in our data file to write a the permeability x' let's move for the equals keyboard and we go back to the permeability in a second what is equals what is the equals key board across key words is a something like box okay so you are defining a box and for each box you are going to assign the permeability for example write equals keyboard okay and equals keyboard is finishing with the slash okay so you have equals keyboard and you are going to finish that equal a key goes with this ax / insightiq was a keyboard you are going to identify param X / my and turns it okay so it means that permeability in the x-direction permeability in the y-direction and permeability in the z direction right after permeability in the term x you need to have space and number after space is is showing the permeability of the in the X direction for example here we have to pay abilities in the X direction we have 10 admitted RC and 100 milli Darcy for the X and for the y direction we have 100 milli Darcy and 100 mini Darcy for the Z direction so these values are showing the permeability values and because we are using their field and unit so it means that this desert Milla Darcy's okay so right after Pam bility the number of permeability the value of MVT you need to have a space so it doesn't matter that you have one space or couple space but right after the spaces you are going to have six values what are these six values first when you is showing the starting point starting grids okay so here for example our starting is in X Direction is 1 root number one okay so in the X direction so this is x1 here for example and the second value this one is showing the end of end value or an end of the box in the X direction so we want to have a 2x start from the grid number one and finishing point number 10 so we are going to assign for all these grids in the x-direction the third value is showing the starting point for their boy so a starting point get it for the y is a gate number one and fourth one is showing the end of the end point for the Achilles in the Y direction so we are because we are going to have all these gates same pair X so our Y Direction gates is starting from 1 and it's ending in 10 so we write 1/10 1/10 and third value third fifth and sixth values are showing the z direction if you see here in this reservoir we are going to assign different permeability for the top layer and different permeability for the last two layers okay so our top layer is going to have ten milli Darcys ten milli Darcys and last two layers are going to have 100 milli Darcys so top a top layer is starting from grid number one finishing in gate number ten in the x-direction starting from number accurate number one the y-direction and finishing in period number ten in y direction and in the Z direction is starting from period number one and finishing grid number two so it's starting from layer 1 and finishing layer two so basically this is just one layer so we assign 10 milli darcy for the top layer similar for the last two layers we are going to assign 100 milli darcy for these two layers in the x-direction and these two layers is starting from gibbet number 1 in the x-direction is finishing in grid number 10 in the x-direction and for the y-direction is starting from carrot number 1 finishing in gate number 10 and for the Z Direction is starting frame from period number 2 and finishing in gate number 3 so we assign 100 minute RC for last two grids so if you want to have a different layers with different parameters you can just copy and paste this section and the write exactly the same in the same manner for the permeability in the y-direction and permeability in the Z direction we are going to have a homogeneous reservoir and is going to have 100 meters in the egg in the Y and 100 meters in the Z direction so what will be the box of that parent example my base pair pair and parents that is it basically it's going to be whole reservoir so it's starting from period number one and in the X direction and is finishing in period number ten in the X direction this is starting from period number one in the Y direction and finishing gate number ten in the Y direction and scan I start from a grid number 1 in the Z direction and it's going to finish in get it number three in the set direction and we are going to do the similar policy procedure for the set direction so in this way we assign the different and permeability is for the for our reservoir and we consider the different variability in the different layers so in this way you can you can assign different parameters for differences so for the porosity you have for the porosity you need to use follow keywords so this product after this polar keyboard we are going to assign the pores it is because the porosity is homogeneous in the reservoir so you can you have two options option one is to write for example you have it's very similar to disease and dividing X so you have 300 reticulate and you are assigning zero point when you want porosity for the each of these grades for all these three hundred cakes so this is the one way to write their porosity but if you have a different port city in different layer you need to impute this porosity inside the equal and write exactly the same as per mix for example let's remove this part for now just if for example if you want to have if you want to remove something from your data file and you it's better to make it comment and as you know it's like a - - is making gay anything comment so for the comment we are using - - so just for now right - - for the porosity for the keyboard and we are going to define the porosity inside the a quad so just copy one of these so we are going to say portal will be what is the value what will be the value of Peru it will be for example 0.2 anyone and you can assign it's gonna start from trick number one is going to finish indicated number ten in the X direction it's going to start from accurate number one in the Y Direction is going to finish in the gate number ten in the Y direction and it's going to be all reservoir so is start from gate number one in the Z direction and it's going to finish in the current number three in the Z direction so this line is doing exactly the same work as this line so it's up to you you can use any of these options to define the porosity for day for your reservoir and so basically these stories are the essential periods for to build a simple carried in the data file so what you need to do is just define the size of the yogurt bit using the x dy DZ and as I'm permeability in the each direction and porosity for each of your cells and with the equals keyboard you can have a box and you can assign different porosity and permeability for the different layers using this matter and at the end of your curious section just right this is a I AI n I T so what does mean it's meaning that we want to have these geometry usual geometrics in our accurate processor as well that so at the end of the end of the day when you are going to process your it when you are going to when you want to see your reservoir properties if you write iron IT and they end up your grid section you have initial the initial conditions or you can take a picture of the initial condition in case you want to have in your reports so basically this is what you need to know about accurate section and the next section next video I am going to talk about the prep section hello my friends in this video I am going to teach you how you
