The Well Directional Survey table contains header information about directional surveys which have been performed on a wellbore. This downhole survey charts the degree of departure of the wellbore from vertical and the direction of departure. Since many directional surveys can be conducted on a wellbore, the survey number is included as part of the primary key to uniquely identify the survey. |

Flow Model
Flow Model: The flow model is used to describe the flow connections for the product be transported to a facility where it can be produced/treated, stored, processed, refined, or transferred for eventual sale. Below is showing a core structure of the flow model, which is made up of model,network,unit, port and connected node. More detailed information please refer to Flow Model chapter.FlowModel Introduction

|
Identifies a entity this flow model represents for. |
|
Identifies a facility or a well instance. |
|
Identifies type is facility or well. |
|
Identifies the context facilities of the model. |
|
Defines the external port in another Product Flow Model to which an external port in this model is connected. |
