hunting clear-run® system overview

In full Commercial application, Clear-Run® hasdelivered improved Rig-Time efficiency through theremoval of tubular preparation time and theachievement of benchmark safe make-up speed andconnection integrity levels. A Pipe Dope is not requiredat any point in the manufacture, storage or runningof OCTG deployed using the Clear-Run® system.Corrosion inhibition and anti-galling properties areintegral Clear-Run® features and there is norequirement for connection cleaning and preparationon the outward or inward journey, to and from theWell Site.

Key components of the Hunting Clear-Run® systemare recyclable/bio-degradable, adding to the overallreduction in environmental impact achieved by theremoval of Dope from the entire process.

The Hunting Clear-Run® Advanced TubularSystem sets a new benchmark in Oilfieldbest practice, offering a high valuealternative to traditional ‘dope-based’ OCTGprocesses. Clear-Run® delivers greatlyimproved Operational, Commercial andSafety performance and completely removeskey negative Environmental aspects ofestablished industry practice.

System Overview

From the very first exploration wells through to theincreasingly complex and environmentally sensitiveprogrammes undertaken in the Oil & Gas industry oftoday, 'Oilfield Tubulars' have been handled using aprocess with the following inherent problem areas;

Contamination of the Well Bore andFormation with Pipe Dope

Fouling of Down Hole Equipment with PipeDope

Costly Onshore and Offshore ThreadCleaning and Preparation

Frequent Incidence of Connection Galling

'Dirty', Unsafe Workspaces Shop/Yard/Rig

In-Storage Connection Corrosion

High Residual Environmental Impact

The Hunting Clear-Run® Advanced Tubular Systemremoves or reduces all these negative aspects, yieldingdirect savings in Cost and Time and greatly reducingthe Environmental impact of OCTG operations.

A significant technological advancein OCTG anti-gall treatment, thiscomponent of the Clear–Run® systemhas been developed by Hunting incollaboration with our coatings technologypartner company, MP (Eastern).

High performance friction reduction andcorrosion resistance without Dope, enablingfaster, cleaner make-up of tubulars at the WellSite. ‘Transparent’ and biodegrable characteristicsfacilitate detailed thread inspection without cleaning.Clear-Glide® was developed by Hunting in collaborationwith our technology partner, R.S. Clare.

System Components In addition to the service elements of materialsourcing, connection machining and logistics, the

Hunting Clear-Run® Advanced TubularSystem has three proprietary

product components;

At the Mill / Machine ShopUnder the Clear-Run® system, the need for pipeDope during connection make-up is removed, creatingsignificantly cleaner, safer workspaces. The Clear-Plate® component of the Advanced Tubular Systemprovides anti galling properties to all Clear–Run®

OCTG from this point in the process.

In the Pipe YardImmediately prior to storage, the Clear-Glide®

component of the Advanced Tubular System is appliedto connection threads making all Clear-Run® joints

The Clear-Run® Advanced Tubular System covers the entire OCTG Life Cycle from Mill to Well, throughReturn and Re-Use in a single integrated process. Features and benefits of Clear-Run® at key points in thislife cycle include;

corrosion resistant and ready for offshore runningwithout the need for further cleaning and preparation.Clear-Cap protectors are then used to flag the tubularsas ‘Clear-Run® ready’ and enable quick visual conditioncheck of threads in the Yard and at the Rig Site.

Tubulars returning from the Rig Site require no routinecleaning and corrosion protection treatment priorto re-storage.

At the Rig SiteZero cleaning, zero preparation, zero Dope – justremove the Clear-Cap protectors and run in hole.
