Direct Connect Overview
What is Direct Connect?
Direct Connect is an option in PETRA which provides a quick link to the IHS Enerdeq Browser for importing U.S. Well and Production Data via the Internet directly into your PETRA project. Several import options are available, depending upon whether you are updating an existing PETRA project or importing well data into a new PETRA project. These options include selecting an AOI from a map, using an existing PETRA well list, and selecting from your saved Enerdeq queries, among others. Connection to the Canadian server is also available for access to Canadian Well and Production Data. This document describes the U.S. connections based on PETRA version 3.6.1. Notes related to former versions are included at the end of the document. NOTE: The Direct Connect feature also provides options for linking to IHS Logs, International data, and Landgrid Shape Files via Map; however, these options are not discussed in this guide.
Authorization
Use of this feature requires subscription to IHS Well/Production data as well as Enerdeq authorization, via a Username and Password. If you currently access the Enerdeq Browser, use that same Username and Password in PETRA. If you need to establish this authorization, contact your IHS Account Manager. If you are unsure of the name of your Account Manager, you may contact one of the Customer Care sources listed below: Customer Care telephone: 1-800-IHS-CARE (1-800-447-2273); select options for Enerdeq or PETRA IHS Enerdeq Customer Care email:
[email protected] PETRA Customer Care email:
[email protected]
Initial Setup
You access Direct Connect from the Project menu on the Main module of PETRA. Project>Direct Connect>IHS US Enerdeq or Canada>Import… This displays the submenu selections for importing well and production data, as shown below.

Import Wells from IHS Direct Connect
The Well import option allows you to select your wells from a map-drawn AOI, UWI list, or saved Enerdeq query, among others, depending upon whether you are updating an existing project or importing to a new project. You can also select the data to load and other import options, as well as create reports. TIP: For best results, always import Well data before Production data and set Map Projection before well import when possible. IHS U.S. data locations are referenced to NAD27 datum.
Import Well Data into a New Project
From the PETRA Main module menu bar, select Project>Direct Connect>IHS US Enerdeq or Canada>Import Wells from IHS Direct Connect…
An Enerdeq Database Source screen may display. It provides selection of the U.S. or Canada Well Loader; this depends upon your subscription entitlements.
Select the Database Source, in this case U.S., and click the OK button. The IHS (US) Well Loader dialog displays once the authorization and connection are verified.

Import Production from IHS Direct Connect
The Production import feature provides several methods for selecting wells, including using saved queries, as well as various options for data to load. As with the Well loader, you have the option to save settings for future use. Be aware that Production imports are complete historical replacements for each well.
IHS Production Data Types
A key point in loading U.S. production data is in understanding the difference between IHS production data types. For reporting purposes, many states often roll up production to the Lease level, rather than the Well level. To circumvent this reporting issue, IHS developed an allocation process which takes all lease level production and applies it to individual wells. This technique facilitates mapping individual well production by formation and study of individual well profiles. The IHS allocation process incorporates well tests, allowables, and monthly status to apply the lease level production to individual wells. Any lease level production with insufficient test data for allocation to an individual well is designated as a Multi-well production ID, and may consist of one or more wells’ production, possibly on adjacent leases. In this case, production is assigned to the primary Multi-well API. This procedure results in two types of production within the IHS database: Allocated Production: These data have undergone the allocation process and are currently available ONLY for Texas Oil and Louisiana Oil and Gas. Unallocated Production: These data are reported “as is” (either lease level or well level) from all states. Both Production Types are available with your IHS Production subscription.
Production Import Scenarios
There are two main production import cases you might encounter with your PETRA projects, based upon production type and project area: 1. Texas/Louisiana: for these wells you MUST choose either Allocated or Unallocated production. 2. All Other States: for these wells Unallocated Production Only is the default option; no selection is necessary. NOTE: For projects covering multiple states, such as Texas, Louisiana, and Arkansas, you only need to select the Texas/Louisiana production type since all other states default to Unallocated Production. All production loads in one import for v3.6.1 or later.

Allocated Production – Texas/Louisiana Only
This section describes the entire import process for the specific case of loading production data into any project containing wells from Texas and/or Louisiana only. This example shows the project used for the well data import which contains only Texas wells. You launch the Production Loader from the Main module of Petra by selecting: Project>Direct Connect>IHS US Enerdeq or Canada>Import Production from IHS Direct Connect
NOTE: If this is your first time using the Direct Connect feature, you will be prompted for your username and password. See Well Data section for more information. The IHS (US) Prod Loader initial screen displays. Choose a well selection option to determine the UWI list used for importing production data. An option to restrict by a date when updating production is also available.
In general, use option 1 or 2 for your initial production import, since they use all or most wells in your project. The last choice, I’ll Decide Later, gives you a chance to think about which wells to select before you actually import the data. Select the Source menu to reactivate this screen.

Import Production from IHS Direct Connect
The optional date restriction for updates provides the same choices as in the Well Data Loader and works the same way. This example uses the 10180 wells selected in Main. Clicking the OK button generates an immediate Enerdeq request for a list of production ID’s (PID) for the wells in the UWI list, unless you choose the option I’ll Decide Later. CAUTION: This request can take several minutes to complete. You will NOT be able to cancel this request!
The Status screen displays the results of the PID search: of the 13,079 production ID’s selected, 10,773 will be used in this Texas Allocated import. This is the sum of Allocated PID’s (Oil) and Well PID’s (Gas). The Unallocated (Lease) PID’s are not used. At this point you proceed to the General tab and begin selecting parameters for import.

General Tab This screen provides selection options for production streams and type.
Production Streams
This section provides choices for which streams are loaded; both options can be selected. Load Production into Standard Streams (OIL, GAS, WTR, and DAYSON) Check this option when you want to load data into streams called OIL, GAS, WTR, and DAYSON. The cumulative values are stored in the WELL Zone as CUMOIL, CUMGAS, and CUMWTR. Multiple producing formations are summed together. Load Production into Individual Formation Names Check this option to load data into separate streams by producing formation name. The formation names are selected on the Formations tab. A stream code, such as O, G, W, is appended to the formation name as a prefix or suffix to form the production stream and zone item cumulative (total) names.

Import Production from IHS Direct Connect
Texas/Louisiana Production Type
For projects with wells in Texas and/or Louisiana, you have to choose which production type to load for those wells: Unallocated Only – reported “as is” at well or lease level Allocated Only – assigned to Well level via IHS allocation process
Production Stored As
This option provides selections for storing production as streams, CUMS, or both. Choices are: Load Monthly Production Streams and CUM Values Load Monthly Production Streams Only Load CUM Values Only
Method to Apply Unallocated Lease Production to Individual Wells
This option is important when loading unallocated production from leases with multiple wells. It determines how the lease production is applied to each well in the lease. Load Production into First Well Only Listed in Lease – stores all lease production in the first well on the lease; the remaining lease wells receive no production. Load Production into Each Well in Lease (Subdivide) - total lease production is subdivided equally among all wells in the lease (i.e., 6 wells in lease, each receives 1/6th of total production). Load Production into Each Well in Lease (Store Total) – All wells in the lease receive the total lease production. May result in inflated production! NOTE: This option is ignored when importing Allocated Only production.
Production Available to Load
This section displays the results of the PID query, as shown on the Status screen.
Fluid Types (Streams) to Load
This section determines which Standard streams are loaded, and which fluid types are loaded for individual producing formations. Only the fluid types selected are loaded; uncheck all but OIL, if you only want oil data loaded. Options: OIL DAYS ON GAS WELLS ON WATER Injection Data

Only Import Production Streams that have been Updated on IHS Server
This option is a repeat of that displayed on the initial screen; you can select the update method here, if not chosen previously. Recall that PETRA saves the last import date in memory and uses that when you select an option such as In the Last 2 Weeks. Use the Get Counts button to check how many production ID’s (PID) would be downloaded.
MISC OPTIONS
This section provides various options for import. Check those of interest to you. Load Production into INITIAL COMPLETION Wells Only Select this option when you want to load production into “0000” wells only, for all wells in the project. This restriction is accomplished by matching 10 or 12 digits of the API number, as selected at the bottom of the screen.

This restriction is accomplished by matching 10 or 12 digits of the API number, as selected at the bottom of the screen. Update OPERATOR and Save Current Operator as Historical Operator This option assumes the production data Operator Name is the current operator for the well. When checked, the existing operator name in your PETRA project is copied into the blank Historical Operator field and replaced with the operator name from this import. Update Well SYMBOL CODE from Primary Product Code Select this option when you want to change the existing symbol code in your PETRA project to the updated symbol based upon current production status. Load Producing Fm Name into Well Header This option updates the Producing Formation Name field in the Well Header with the value from the production data import. Store current STATUS in WELL Zone as PDSTATUS This option stores the well status (Active or Inactive) in the WELL Zone as an item called PDSTATUS. Store GATHERER in WELL Zone as GATHERER This option stores the gas gatherer in the WELL Zone as an item called GATHERER. Store Production Tests in PdTest Table This option stores all production tests in the PdTest tables in the database and displays under the IP Tests tab. Display Detail Info in Report This option creates a detailed report of all monthly production values, which can be saved in your project’s REPORTS folder. Update Non-Blank Lease Number with UNIT WELL SERIAL NUMBER This option replaces the non-blank Lease Number with the value of the Unit Well Serial Number, if it exists. In some states this is a Permit number. If Unit Well Serial Number is blank, it will replace the Lease Number with a null field. Do not use “A” in prefix/suffix to designate Allocated Production When loading Allocated Production, this option removes the default “A” prefix/suffix stream code appended to the producing formation name on Totals and Formation tabs.
Use Digits for Matching Initial Well Completions
This option is used only in conjunction with the miscellaneous options for loading initial well completions. It sets the API number of digits used to match with wells in your project.

Choose the Zone in which to store the Producing Formation totals, or use the New button to create a new name. TIP: For best results, always create a new Zone for storing these data rather than placing in the WELL zone. It streamlines data management and project refresh rates.
Zone Items
This section contains a list of the Zone items and associated names. The first 4 items store the cumulative values for Oil, Gas, Water, and Days. When loading production by producing formation names, each stream has a production code appended to the name as either a prefix or suffix, as selected on the Formations tab. The code relates to the stream and type of production loaded. In this case: AO = Allocated Oil

FM Name From
This option allows selection of the format for the producing formation name. Fm Name Code: uses the IHS alphanumeric age and formation code, such as 403BCGM or 354BRNT Fm Name Desc: uses a descriptive code such as BEND CONGL or BARNETT/SH/ Fm Name Code (Age Only): uses the IHS age code only, such as 403 or 354 Reservoir Name: uses the reservoir name, such as BEND CONGLOMERATE GAS or BARNETT SHALE
Prod Stream Name Qualifier
This option allows you to select the application of the stream code as a Prefix or Suffix. Examples are AO_403BCGM for the prefix option and 403BCGM_AO for the suffix option. CAUTION: Be consistent with selection of the Fm Name and stream qualifier formats. Changing these formats for subsequent updates can result in duplication of production, since producing names are unique to each import. For best results, you can save your import settings and reuse them for updates; see later section for more information. PdCum Tab This screen provides options for storing production cum values in the Prod Cums table of your project. Cumulative values are computed by summing the monthly production streams.
PD CUM TABLE UPDATE
This option controls how data are stored in the Prod Cums table. DO NOT STORE in PdCum DB: no data are stored STORE PdCum Data using ProdID as FmName: stores PdCum data, but also stores the PID in the FmName field and the producing formation name in the Altname field. This results in 1 Prod Cum entry for each PID.

Best Practices
1. Be consistent with selection of producing formation names and stream qualifiers (prefix/suffix) on import updates to avoid duplication of production. Use the Save/Load Settings options. 2. Be consistent on the number of digits in your API numbers on import updates to ensure production is stored with the same well. Again, using the Save/Load Settings options will help for imports in which the Initial Completions only, and number of digits used to match the API number, options were selected. 3. Create a Zone dedicated to storing individual producing formation CUMs and related data. This action improves data management and project performance by not overloading the Well zone. 4. Create a WSN list of all wells with monthly production to streamline viewing and analyzing production data.

Import Options for Prior Versions of PETRA
The current document describes the Well and Production Import options available with PETRA version 3.6.1. Not all these options are available in prior versions of PETRA. If you are currently using version 3.4.x or 3.5.x, check here for sample screen shots and discussion, or better still, update to the current version of PETRA.
Changes for Well Data Imports
The Well Data Loader has not changed significantly with PETRA version updates. The main differences in the prior versions are: Import Options>General Tab: fewer options available Import Options> No Directional Survey Tab No 297 File button
Changes for Production Data Imports
The most significant change in the current version (3.6.1) of the Production Data Loader is the revision in selection of Production Data Type. The current version streamlines the import of Allocated and Unallocated Production, especially in multi-state projects which include wells from Texas/Louisiana. In prior versions of PETRA, there were basically 3 Production Import Scenarios based on production type and project area: 1. Single Import – Allocated Production: use this option when your project contains wells from either or both Texas and Louisiana, but no other states. Since Texas Gas is reported at the well level, this option imports all Texas production. 2. Single Import - Unallocated Production: use this option when your project contains wells from 1 or more states, excluding Texas and Louisiana. 3. Dual Imports – Allocated and Unallocated: use this option when your project contains wells from multiple states including Texas and/or Louisiana. For example, a project covering Texas, Louisiana, and Arkansas. Use the Allocated Production type for the Texas/Louisiana wells; then the Unallocated Production type for the Arkansas wells. Sample screen shots and points to note for each of these scenarios, as well as other options, are provided below.

Sum of Allocated and Unallocated – this option applied to Texas and Louisiana, but is no longer necessary, as Texas Gas is reported at the Well level and imports via the Allocated option; Oil and Gas are both allocated in Louisiana
Method to Apply Lease Production to Individual Wells
This option is important when loading unallocated production from leases with multiple wells. It determines how the lease production is applied to each well in the lease. NOTE: The NAME of this option changed in the current version. It always applied to Unallocated Production only, and is ignored when importing Allocated Production.
Options Tab This screen provides a variety of import options, as well as another chance to restrict the import to a particular timeframe, if you did not choose this option on the initial screen.

Dual Production Imports– Texas/Louisiana and Other States
Use this import method for projects containing wells from multiple states including Texas and/or Louisiana. This example uses the same project with wells in Arkansas, Louisiana, and Texas, as described in the previous section. Since this project contains wells from 3 different states, there are 2 IHS Production Types available for loading: Unallocated Production for the Arkansas wells Allocated Production for the Texas and Louisiana wells NOTE: The main change for this import scenario is that it requires 2 separate imports, 1 for each production type. Pre-import Preparation To streamline your workflow before importing production, you should create the following: 1. WSN list containing the wells for the Unallocated Production import. In this case the list contains Arkansas wells only. 2. WSN list containing the wells for the Allocated Production import. In this case the list contains Texas and Louisiana wells only. 3. New zone for storing individual producing formation cumulative values. NOTE: If you prefer to skip these steps, you can use the Search Wells by Data Criteria option for well selection, and create new zone option on the Totals tab. First Import Decide which production type you plan to import first; there is no priority to the order. In this example the Allocated Production is loaded first. 1. Select the WSN list for the Allocated Only import – the Texas/Louisiana wells. This reduces the well list in Main to just those you need for this import. This step is optional, but recommended for efficiency. 2. Launch the IHS Production Loader by selecting Project>Direct Connect>IHS US Enerdeq or Canada>Import Production from IHS Direct Connect 3. Choose the well selection option that works best for you. In this case the WSN list is already selected, so the option Use the 1136 wells in Main module is the best choice.
