  1. Overview Production Reporting(draft specifications)

  2. Production ReportingOutline • Flow Network • Collection of connected Flow Units. • Product Flow Model • Collection of Flow Networks • Product Volume Report • Measurements of p,v,t,q,… in fluid flows. • Production Operations Report • Activities related to production.

  3. Network Unit Port Node Flow Network • Represents a flow system. • Named collection of connected Units. • A unit is a black box that describes the flow into or out of something. • Flow properties can be measured at a Port. • A network may have external ports.

  4. Flow Network – Flow Unit • A black box with ports but an internal network allows drill-down for more details. • A unit can represent: • A complex thing like a platform or separator. • A simple thing like a valve or choke. • Contextual knowledge (i.e., what does this unit represent).

  5. Flow Network – Flow Port • Represents a real world measurement point on a facility. • Has an expected direction (inlet or outlet). • Connects to one Node - may represent a many-to-many connection. • May have an expected Product Flow (for validation purposes) – e.g., oil production or gas injection. • Future - Control point (across two ports)

  6. Flow Network – Port Direction • The direction is the intended direction of flow. • A change in pressure across a unit can change the actual flow direction at a port. • In the Product Volume Report: • A positive volume represents an intended direction (i.e., a flow out of an outlet port or into an inlet port). • A negative volume represents an unintended direction (i.e., a flow into an outlet port and out of an inlet port).

  7. Flow Network – Expected Product Flow • Pairs of product kind and flow kind where: • Product = oil, gas, condensate, aqueous, oleic, vapour, water, carbon dioxide gas, etc. • Flow = production, injection, consume, import, export, gas lift, overboard, etc.

  8. asserts a connection Unit Port Node Flow Network – Node (artificial concept) • All ports that are connected to the same node are connected to each other. • For an actual flow diagram the graphics may ignore the node.

  9. Flow Network – Flow Assumptions • Steady state fluid flow across nodes and ports. That is, pressure is constant across internally and externally connected ports and nodes. • Conservation of mass across a node or port. • The temperature and other properties can vary between connected ports. • Pressure can vary internally between ports on a unit.

  10. B1 B2 B A A2 B3 B Internal Network C1 B2 B1 C B3 Flow Network – Internal Network of a Unit • Corresponding ports have the same name (i.e., they are logically the same port). • There is no pressure change across ports or nodes. Thus, there is no pressure change between ports A2 and C1.

  11. Flow Network – What good is it? • Defines the connectivity status of one fluid system over time. That is, how fluid “could” flow. • Defines measurement points within the fluid system. • The flow connectivity is independent of physical descriptions. • The connectivity can be tailored to specific business scenarios. • Requires something else to capture actual flow properties over time.

  13. Production ReportingOutline • Flow Network • Collection of connected Flow Units. • Product Flow Model • Collection of Flow Networks • Product Volume Report • Measurements of p,v,t,q,… in fluid flows. • Production Operations Report • Activities related to production.

  14. Product Flow Model • Defines the flow behaviour of something (normally larger installations). • Collection of Flow Networks. • The model is represented by one network. • The other networks represent Flow Units within a network. • External ports. • Allows models to connect.

  15. Product Flow Model - Model Hierarchy • Model – Collection of networks. • Network – Collection of connected units. • Unit – Black box with ports. • Port – Allows flow in or out. • Node – Allows ports to connect.

  16. Product Flow Model - Summary • Flow system defined by a Network (Units with connected Ports). • Unit can represent anything (big or small). • Steady state fluid flow across ports/nodes • Conservation of mass across ports/nodes. • Properties are assigned by the Product Volume Report.

  17. Product Volume ReportRequirements • Simple (e.g., one well) or complex (e.g., one field). • Fluid measurements at a point in a flow stream. • Multiple measurement points. • Multiple flow streams • Multi-phase streams • Multiple reporting periods • Multiple properties

  18. Product Volume Report -Problem Analysis • ProductionML – meets a subset of Partner Daily Reporting Project requirements • Typical Recurring Pattern • Where - well, field, platform, tank, flowline, vessel, … • Flow – production, injection, gas-lift, import, export, consumption, inventory, … • Product – oil, gas, water, condensate, diesel, aqueous, … • Period – day, month, year, mtd, ytd, cumulative total, … • Measurements – volume, flow rate, pressure, temperature, density, component concentration, mass, differential pressure
