Case Studies

Read the case studies from Perigon where the CST tool has been used successfully in different settings!

Discover how our Cement Support Tools (CST) have transformed drilling operations for major operators around the globe.

From setting environmental cement plugs to managing severe downhole losses, these case studies showcase the versatility and reliability of CST in various challenging scenarios.

Setting an environmental cement plug from vessel

Well Cementation and Wellhead Removal Campaign (Rig Chase), with the use of CST.

Hesitation cement squeeze job using CST as base

Complete losses occurred when a major operator in the North Sea was drilling a 16” section below a 17” liner.

Cement squeeze job using CST as base

There had been severe losses when a major operator in the Gulf of Mexico was drilling a 20” section below a 16” casing.

Setting multiple balanced plugs in one run using CST as base

A major operator in the North Sea successfully plugged and abandoned a well with 6 separate cement plugs.

Use of CST as base in a high angle well

A major operator deployed a Cement Support Tool (CST) in a 82° well @ 4205m to use it as a base for a kick-off plug.

“The Cement Support Tool has become essential for our operations. Its ease of use and high success rate in cement plug operations have significantly improved our operational efficiency and productivity. We’ve cut our cementing time by nearly half.”

SamuelRig Manager, North Sea
“We are saving between 18 and 32 hours of operational time using the CST instead of a

bridge plug for our plugs, saving time by not having to scrape and make up the BHA to set our base.”

Industry ProfessionalLarge O&G Company in Europe
“The CST has allowed us to plan for considerable shorter cementing operations, increasing our efficient rig time and keeping our plug cost at lower intervals than before.”
Industry ProfessionalCementing Engineer, North Sea
“Since we started using the CST, our cement plug operations have become significantly

faster and more reliable. We’ve managed to cut down our cementing time by 35%, which has been a huge benefit.”

Industry ProfessionalFluid Engineer, West-Africa
“Simply put there is always a CST on my rig since we can save so many hours by having it

available if we require it.”

Industry ProfessionalCementing Engineer
“I have not set a balanced plug in over 5 years without being supported by the CST in open hole and so far it has a 100% success rate.”
