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

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- Are a point in time view that will change over the life of a well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

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.

Well Classification Facets

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
