Well Status & Classification
Problem Statement:
Well status and classification are some of themost widely abused terms in the oil and gasindustry
There are many different definitions being usedwith very little consistency in terms of terminologyor semantic meaning.
Wells may be grouped in many ways butcompanies often try to establish a single wellclass or status
Consequently, data gets aggregated resulting incomplex and confusing codes there are literallythousands of these

Well Status & Classification
This results in:
- Misunderstanding by users and organizations- Problems with regulatory reporting and
compliance
- Poor decisions around property acquisition anddivestiture
- Challenges with data mapping
- ..
This has a significant impact on businesses

What is a Well? Phase II
Establish baseline definitions for wellstatus and classification over thelifecycle of a well that can be used forcommunication and comparisonpurposes.
Define a baseline symbol set that can beused to represent well classification and
status on a map.Add review of Eastern States andAustralian States to WIAW Phase I

Well Facets
Well status and classification are essentially differentways of describing wells so that people can find theright set of wells these are facets
A facet comprises clearly defined, independent
properties of an object
Facets contain values that are mutually exclusivewith values in other facets
Facets may be hierarchical in nature
Sub-facets or qualifiers By combining information from many facets, users
can group or identify wells for many key functions

Well Status and Classification
There are two types of facets that we deal with:
State based facets:
- Provide a snap shot of where a well is in business terms
- Are a point in time view that will change over the life of a well
- Will generally change in a predicable, sequential pattern that can betied to the well lifecycle
Classification based facets:
- Provide a method to group wells based on a characteristic of a well,such as whether it is producing or injecting.
- Have values that may change over the life of a well- Have no set pattern to changes
- Are not tied to the well lifecycle
- Are essentially an attribute of the well

Well Status Facets
Business Life Cycle Phase State: Definition and Values
Business Life Cycle Phase is a collection ofactivities and conditions, that are grouped accordingto business significance, describing where an E&P
asset (in this case a well) is at within its progressivehistory. Phases are related to businesssignificance and are not related to time.

Fluid Type: Definition and Values
Fluid Type is the class of principal fluid in thewellhead stream. This facet is not intended to be adescriptor of the fluid composition, it is a general
classification.

Well Status and Classification
The first version of the Well Status and Classificationproject is now complete
This will be released to PPDM members for reviewand comment in the next few weeks
The facet definitions, values and plot symbols will bemade available to industry as a whole through thePPDM web site
Success will depend upon practical implementation talk to your vendors and get involved
