Production Data Management and Analysis (PUMA) is designed
to be the exploration and production (E&P) industry's
most advanced Field and Well Management IT Tool, and is a joint
project between Tigress Ltd and Shell International.
PUMA is used by the E&P industry for the analysis,
manipulation and easy visualisation of recent and historical
production data. It performs all of the typical objectives of
reservoir performance analysis and forecasting, including
estimation of original hydrocarbons in place, analysis of past and
present performance, prediction of future performance under current
conditions, estimation of reserves and recovery rates under various
conditions and updating of analysis with new data during life of
field. PUMA is a client server solution for Unix and NT servers,
and is fully integrated with the Tigress Project Data Store (PDS) and other Tigress
applications.
PUMA helps with short-term production gains, for example
identification of under-producing wells and identification of
candidate wells for stimulation treatment and workovers. It is also
used for long-term reserves gains through early identification of
inappropriate reservoir management studies, including inadequate
areal drainage and over or under injection.
Benefits
The benefits of PUMA include:
- increased efficiency and time savings
- easy management of large data volumes
- quicker identification of production problems
- increased production potential.
Functionality
PUMA functionality includes:
Data loading
Features include:
- By PBAscii or a generic data loader, utilising user-defined
formats.
- All data are stored to POSC Epicentre compliant tables.
- Data can be loaded into any well hierarchy level (well,
conduit, completion and so on).

Data selection
Features include:
- map-based object selection and data display
- well hierarchy selection
- list-based object selection
- sorting and grouping can be done by:
- physical items (such as wells, wellbores, wellbore conduits,
wellbore completion intervals, reservoir elements)
- logical items (such as patterns, operators, concessions)
- groups of physical and logical items
- queries and filtering include:
- multi-level production/completion queries
- queries at any physical/logical hierarchy
level.

Data visualisation
Features include:
- XY Plots with multiple X and Y axes can display anything
against anything.
- Full control over crossplot design and the entire setup can be
saved to a template.
- Up to 18 curves on a single plot.
- Multiple plots (up to 16) per plot window.
- Easy to create object comparison plots and normalised time
plots .
- Curve fitting (polynomial, linear, exponential).

Decline curve analysis
Features include:
- Decline curve analysis for oil, gas and water rate curves.
- Designed to produce oil, gas and water rates, gross rates, oil
water ratio and water cut forecasts.
- The forecasts can be manually edited or projected to any start
date in the future.
- The decline curve can be forced through a specified technical
reserve.
- Calculates the technical reserves (or ultimate reserves) and
the abandonment date for the curve.
- Analysis can be performed on any level in the hierarchy.
- Multiple forecasts can be created for each data item.

Performance indicators
Features include:
- pre-defined indicators:
- Lift Performance Indicator (LPI)
- Well Inflow Quality Index (WIQI)
- Gas Utilisation Factor (GUF)
- user-defined indicators can be generated and stored
- batch calculation of Well Performance indicators
- link to other applications facilitate generation of IPR and VLP
data.

Reporting
Features include:
- design to report anything against anything
- full control over report designs features (columns positions,
fonts, types)
- report designs saveable to templates
- spreadsheet like background grid controls
- easy to create object comparison reports.

Macro language
Features include:
- stores an entire analysis sequence including data selection,
crossplot and report templates, and well performance indictors that
were applied
- record and replay stored procedures.

Auto-sequenced printing/plotting
Features include:
- applying a selected plot / report template to a sequence of
selected objects (for example wells, conduits, reservoir)
