Well life cycle value? metrics. learnings?
25 February 2019

Each Well's life cycle program consists of several individual project's that are then  phased to meet operational needs, for example; - Drilling, completion, production, well servicing, intervention, workover and final abandonment. 

How are companies measuring each project phase and aligning all to determine overall well-life-cycle efficiency and effectiveness? 

Furthermore, how key learnings (good/bad) are being translated and sustained into future programs/projects?

Specific references to further inquire? appreciated.

A far better process would be to have a system capable to measure and 'label' all the real and EVIDENT (major, minor and mini) problems' that exist. Make a prioritised list of these and then work to correct* them (who, when, how). 

To deliver this people must want to change.

Note: * 2018 SPE JPT article was full of usual 'intellectual noise' and has not one investigative or concluding corrective action stated (i.e. who is going to do what when and how?)

Until we as an industry move away from NPT and NLTI, little will change, no matter how big the EVIDENT data trail is.

As an example presented to promote further discussion, this 2018 SPE JPT article presents and discussed the value opportunity in well data analysis and big data analytics, regards, Nick

Excellent question Peter,

From my data management focused perspective, a key technical base line is good quality well engineering records throughout the entire well life cycle. 

Some UK NS wells are 40 to 50 years old, so access to legacy well engineering data can be a challenge.

I understand that the key documents for the full well engineering life cycle are (I think) described in the The Guidelines for Decommissioning of Wells, as issued by Oil & Gas UK, Version 6.

Keeping these 
full well engineering life cycle documents (ideally digitally enabled, e.g. with OCR) as a key deliverable will enable:

(i) good after action review (AAR) and lessons learned processes

... and ...

(ii) data driven analysis, data analytics and future (re)intepretation, in the age of digital well data and information capture.

Regards, Nick
