2 Exercise Select the plot symbols from the two lists of values that most closely match the well status values for: US Canada Rest of the World 2

3 Well Status & Classification Problem Statement: Well status and classification are some of the most widely abused terms in the oil and gas industry There are many different definitions being used with very little consistency in terms of terminology or semantic meaning. Wells may be grouped in many ways but companies often try to establish a single well class or status Consequently, data gets aggregated resulting in complex and confusing codes there are literally thousands of these 3

4 Well Status & Classification This results in: - Misunderstanding by users and organizations - Problems with regulatory reporting and compliance - Poor decisions around property acquisition and divestiture - Challenges with data mapping -.. This has a significant impact on businesses 4

8 Phase II Establish baseline definitions for well status and classification over the lifecycle of a well that can be used for communication and comparison purposes. Define a baseline symbol set that can be used to represent well classification and status on a map. Add review of Eastern States and Australian States to WIAW Phase I 8

11 Phase II Establish baseline definitions for well status and classification over the lifecycle of a well that can be used for communication and comparison purposes. Define a baseline symbol set that can be used to represent well classification and status on a map. Add review of Eastern States and Australian States to WIAW Phase I 11

12 Well Facets Well status and classification are essentially different ways of describing wells so that people can find the right set of wells these are facets A facet comprises clearly defined, independent properties of an object Facets contain values that are mutually exclusive with 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 12

13 Well Facets Oil Well Facet: Fluid Type = Oil Producing Oil Well Facet: Wellbore Status = Producing Facet: Fluid Type = Oil Operated Producing Oil Well Facet: Wellbore Status = Producing Facet: Fluid Type = Oil Facet: Operatorship = Operated Facets can stand-alone or be grouped 13

14 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 be tied 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 14

16 Well Status Facets Business Life Cycle Phase State: Definition and Values Business Life Cycle Phase is a collection of activities and conditions, that are grouped according to business significance, describing where an E&P asset (in this case a well) is at within its progressive history. Phases are related to business significance and are not related to time. Planning Drilling Completing Producing Disposing 16

17 Well Classification Facets Fluid Type: Definition and Values Fluid Type is the class of principal fluid in the wellhead stream. This facet is not intended to be a descriptor of the fluid composition, it is a general classification.

22 Exercise Decompose the well status values into the PPDM facets Select the PPDM symbol that is most appropriate based upon Wellbore Status and Fluid Type 22

23 Well Status and Classification The first version of the Well Status and Classification project is now complete This will be released to PPDM members for review and comment in the next few weeks The facet definitions, values and plot symbols will be made available to industry as a whole through the PPDM web site Success will depend upon practical implementation talk to your vendors and get involved 23
