Monthly Allocation Setup
Allocations, the monthly and daily estimates for oil, gas, or water production from a site or sites, must be set up before being calculated. A quick workflow is to first set up the Monthly Allocations then duplicate the settings for use with Daily Allocations. Prior to computing Monthly allocations, Daily data for that site must exist in the database. Allocations are NOT performed at a well level instead they are performed at a product level such as oil, gas, water, etc. Therefore, each product allocation must be setup individually. To begin, click on Monthly Allocations Setup in the Monthly Processes Tab. The first time in, the following screen will be presented. The left side of the display shows any allocations that have been previously setup. The right side displays the actual setup for whatever allocation you click on. From this panel, a period can be added, removed or modified. An allocation set up can also be edited in this panel by highlighted the desired allocation. Click Add Allocation. From the selection display, pick the first product to allocate. After the first product has been setup, other product setups can be duplicated. If the initial setup is satisfactory then for additional products, click save for each new product. If not, changes can be made as needed. For a first entry, a configuration window will open. Click on Change How I View Sites at the top of the window to use either User Ref or Site Name to identify allocation sites. Move the items from the right side of the window to the left side of the window. When done, click Save Changes. This will open a well/product selection window. The default display will contain state and field entries. Close the Monthly Allocation Setup window and then reopen. The new display layout will be presented. As an example setup, an allocation for the Demo Battery down to two target wells. First, click on Add Allocation. The selection window will open. Find the Demo Battery and click on the product to allocate. In this example, click on the Demo Battery, Oil. The next window allows defining the beginning production month. Insert the starting month. The format for the start period is MM/YYYY. Add a Description if desired. Click Save. The next window will present a listing of all the Available Target Well/Products that can be allocated to the demo site. Note ONLY oil products are listed as this is the product being setup. Click on the desired target wells/oil products so they move over to the left side of the display. Your screen will now look like this. Test Derivation Method Options Three different algorithms are available for directing how test data will be handled within the allocation algorithm. For Daily Allocations, use the Fixed Ratio option. This method is more accurate than either the simple days x test method or the Weighted Test. Below are the three derivation methods explanations Fixed Ratio, default option Allocation based on monthly entered test relationship Days * Test
- of days * test value equal theoretical production value
Weighted Test Average test value for Days * Test Click the appropriate radial button and Save Changes. Create an allocation for a Water Product Click Add Allocation and select the Demo Battery - Wtr. Because another product was setup, the program will assume all additional product setups follow the same pattern. This means that the next window will have the same Start Period as the Oil setup and the same wells/Wtr Products will be assigned to this new allocation. Save Changes. If one of the assumed products isn't allocated, remove that product from the displayed allocation. For a second allocated product, repeat the steps above. To save time, AnalystX2 will present the new product as if it had been entered previously. Click Save.
