This document describes how to use the suite of Wellsite Information Transfer Standard Markup Language (WITSML) operators.
The TIBCO WITSML adapter connectivity solution is implemented as a suite of fourteen global Java operators that allow a StreamBase application to connect to a WITSML data store, and to allow read, write, and delete operations on the log, well, wellbore, and trajectory data types.
The TIBCO WITSML connectivity solution is intended for the oil and gas industry to retrieve and send well data between well operators, service companies, and regulatory agencies.
The operators are designed to work with the client-server API WMLS STORE interface; the WMLP PUBLISH interface has not been implemented.
The list of supported operations and operators is described below.
The WITSML operators are members of the Java Operator group in the Palette view in StreamBase Studio. Select the operators from the Insert an Operator or Adapter dialog. Invoke the dialog with one of the following methods:
-
Drag the Adapters, Java Operators token from the Operators and Adapters drawer of the Palette view to the canvas.
-
Click in the canvas where you want to place the operator, and invoke the keyboard shortcut
O V
-
From the top-level menu, invoke
→ → .
From the Insert an Operator or Adapter dialog, enter witsml
to narrow the list of operators. Then select one of the following WITSML operators, and double-click or press :
-

This section describes the properties you can set for a WITSML operator, using the various tabs of the Properties view in StreamBase Studio.
Name: Use this required field to specify or change the name of this instance of this component, which must be unique in the current EventFlow module. The name must contain only alphabetic characters, numbers, and underscores, and no hyphens or other special characters. The first character must be alphabetic or an underscore.
Operator: A read-only field that shows the formal name of the operator.
Class: Shows the fully qualified class name that implements the functionality of this operator. If you need to reference this class name elsewhere in your application, you can right-click this field and select Copy from the context menu to place the full class name in the system clipboard.
Start with application: If this field is set to Yes (default) or to a module parameter that evaluates to true
, this instance of this operator starts as part of the JVM engine that runs this EventFlow module. If this field is set to
No or to a module parameter that evaluates to false
, the operator instance is loaded with the engine, but does not start until you send an sbadmin resume command, or until you start the component with StreamBase Manager.
Enable Error Output Port: Select this check box to add an Error Port to this component. In the EventFlow canvas, the Error Port shows as a red output port, always the last port for the component. See Using Error Ports to learn about Error Ports.
Description: Optionally enter text to briefly describe the component's purpose and function. In the EventFlow canvas, you can see the description by pressing Ctrl while the component's tooltip is displayed.
This section describes the properties on the Operator Properties tab in the Properties view for the WITSML operators. Enter all text fields as string literals, not as expressions.
All WITSML operators have a common set of properties:
Property | Type | Description |
---|---|---|
Service URI | string | The URI that points to the WITSML service endpoint. |
Enable Authentication | check box | When enabled, the adapter uses the given user name and password to authenticate with the server. |
Username | string | When authentication is enabled, this user name is sent as part of the credentials. |
Password | string | When authentication is enabled, this password is sent as part of the credentials. |
Witsml Version | combo | Specifies which WITSML version is used when performing operations against the server. Depending on the version selected, ensure that the input schema to the operator matches the WITSML specification for that version. Currently, the operators' proposed schemas generate 1.3.1.1 schemas. If 1.4.1.1 is required, the operators' schemas can be used as a guideline and modified to conform to the 1.4.1.1 specification. |
Read Timeout (ms) | int | Specifies the number of milliseconds to allow to pass before failing on a read. Default: 30000 |
Connect Timeout (ms) | int | Specifies the number of milliseconds to allow to pass before failing on a connection. Default: 15000 |
WITSML Date Format | string | The date format used by the WITSML server. The date format supplied must be a valid pattern for SimpleDateFormat |
Enable Status Port | check box | When enabled, a status port is available to emit status tuples for various events of this operator. |
Log Level | INFO | Controls the level of verbosity the adapter uses to issue informational traces to the console. This setting is independent of the containing application's overall log level. Available values, in increasing order of verbosity, are: OFF, ERROR, WARN, INFO, DEBUG, TRACE. |
Generic WITSML operators Read/Write/Delete have two additional properties to specify the main and child objects to query:
Property | Type | Description |
---|---|---|
Main Object | string | The main object to query against. For example, if you want to query for log data this value would be logs , or for rig data this value would be rigs .
|
Child Object | string | The main object to query against. For example, if you want to query for log data this value would be log , or for rig data this value would be rig . When using the operator input schema with this field, a tuple schema is used as the field schema to run a query with.
|
All WITSML operators have a common set of proxy properties:
Property | Type | Description |
---|---|---|
Use Proxy | check box | Use a proxy server to access the URL. |
Proxy Host | string | The proxy server host name or IP address. |
Proxy Port | string | The proxy server port number. |
Proxy User | string | The username to use with the proxy if required. |
Proxy Pass | string | The password to use with the proxy if required. |
Use the Concurrency tab to specify parallel regions for this instance of this component, or multiplicity options, or both. The Concurrency tab settings are described in Concurrency Options, and dispatch styles are described in Dispatch Styles.
Caution
Concurrency settings are not suitable for every application, and using these settings requires a thorough analysis of your application. For details, see Execution Order and Concurrency, which includes important guidelines for using the concurrency options.
Each operator has only one input port, which is used to start a data operation to the WITSML store.
Each WITSML operator embeds a set of proposed full 1.3.1.1 schemas for each operation type that you can use as a starting point when defining the schemas for the witsml field.
The best way to start is to import the proposed schemas for each operator by selecting the Import Proposed Schemas hyper link in the top right corner of the Operator Properties tab of the Properties view for each operator. Specify the name of an EventFlow module file, and the selected schemas are imported as Named Schemas into the Definitions tab of that module.
Field Name | Field Type | Description |
---|---|---|
witsml | list(tuple(witsml fields)) | This is the main witsml field. If this field is missing or empty, the least amount of schema for the data type is used when
querying the data store. For example, if this is a read well operator and the witsml field is missing, it is assumed that
you are requesting only the UID field from the server. This list of tuples can be as few or as many fields as required. For
example, you can provide the following to request only the UID for a well. Schema - list<tuple<uid string>>> Example usage - list(tuple('abc123' as uid)) as witsmlAnother example for a read operation to query for any well with a state of fl or oh but return country, state, and county would be: Schema - list<tuple<country string, state string, county string>>> Example usage - list( tuple(string() as country, 'fl' as state, string() as county), tuple(string() as country, 'oh' as state, string() as county) ) as witsml |
Each WITSML operator has only one fixed output port. The port delivers the results of executing operator commands. There also is one optional Status output port if the operator's Enable Status Port option on the Operator Properties tab is selected.
The Results Port differs for each WITSML read operator.
Field Name | Field Type | Description |
---|---|---|
logs | tuple | Contains the logs retrieved from the WITSML store as a result of a query received on the input port. This port's schema is determined by the input ports schema. The fields from the input schema's witsml field element data type (the tuple schema in the list) is used to create the schema in this output. |
passThrough | tuple | The input tuple is passed through to the output using this field. |
Field Name | Field Type | Description |
---|---|---|
wells | tuple | Contains the wells retrieved from the WITSML store as a result of a query received on the input port. This port's schema is determined by the input port's schema. The fields from the input schema's witsml field element data type (the tuple schema in the list) is used to create the schema in this output. |
passThrough | tuple | The input tuple is passed through to the output using this field. |
Field Name | Field Type | Description |
---|---|---|
wellbores | tuple | Contains the wellbores retrieved from the WITSML store as a result of a query received on the input port. This port's schema is determined by the input port's schema. The fields from the input schema's witsml field element data type (the tuple schema in the list) are used to create the schema in this output. |
passThrough | tuple | The input tuple is passed through to the output using this field. |
Field Name | Field Type | Description |
---|---|---|
trajectorys | tuple | Contains the trajectorys retrieved from the WITSML store as a result of a query received on the input port. This port's schema is determined by the input port's schema. The fields from the input schema's witsml field element data type (the tuple schema in the list) are used to create the schema in this output. |
passThrough | tuple | The input tuple is passed through to the output using this field. |
The Status Port, when enabled, is the same for all WITSML operators.
Field Name | Field Type | Description |
---|---|---|
type | string | Describes the type of status message: INFO , WARN , ERROR .
|
action | string | The type of action this status message is about. |
object | string | A formatted string with any object data associated with this status message. |
message | string | A human readable message that describes the status. |
time | timestamp | The time of the status message. |
inputTuple | tuple | A copy of the tuple that started the operation that this message is associated with. |
The Log Data Converter operator is a special case operator that takes in the output from the Read Log operator and converts the string data in the logs.log.logData.data field into actual tuples.
The operator works by matching the logCurveIndex mnemonic field to a data schema field, if a field is present with the name the value will be set. Optionally you can also do mapping of mnemonic values to a schema field using the Data Mapping property.
The input to this operator must match the output schema of the Read Log operator, the operator will convert the logs.log.logData.data field from a list(string) to a list(tuple) using the provided data schema.
The Log Data Converter requires the following parameters across the Operator Properties, Edit Schema, and Mapping tabs:
Field Name | Field Type | Description |
---|---|---|
Data Schema | Schema | This is the schema that will be used as the log data conversion output. |
Data Mapping | Map | This property specifies which log curve info mnemonic values will be converted to which data schema field. If a field in the data schema does not match any from this map, then the system tries to match the mnemonic directly to a data schema field. |
Output Type | drop down | The type of output to convert the log data into.
|
Output Tuple Per Row | check box | If enabled, a tuple will be output per log data row instead of one tuple with a list of data rows. |
Missing Data Value | string | An optional value to set for fields that have no value. |
Include Missing Fields | check box | If enabled, then fields in the schema that cannot be matched to a Log Curve also receive the missing data value. |
WITSML Date Format | string | WITSML server's data format. |
Enable Status Port | check box | If enabled, a status port will be available which will emit status tuples for various events of this operator. |
