Following our unrivalled success in the offshore arena with a state-owned oil company in the UAE, Odfjell Well Services (OWS) recently won another significant contract for this client as the primary supplier of a Drilling Scraper.
Topics: Wellbore CleanUp
The client was looking for a solution to drill a highly deviated deep well (14,000 ft) through numerous depleted zones, which increased the risk for losses and differential sticking. In addition, there was also a requirement to scrape a lower completion packer setting depth inside the 9-5/8” casing.
OWS supplied the DrillRdillo (DRD), a 360° contact robust scraper tool that withstands harsh drilling conditions. With the DRD in the BHA and the knowledge that this expandable scraper has been thoroughly tested under extreme drilling conditions, the client can focus entirely on drilling this challenging well, and also save a dedicated WBCU trip.
While drilling the well to total depth, the client experienced a loss of signal with MWD tools and decided to pull out of the hole. An overpull of 25,000 lbs was observed due to differential sticking. They activated the drilling jar with 25,000- 30,000 lbs overpull to free the pipe, but the pipe was stuck. Consequently, they attempted to rotate the pipe with a torque limit set at 30,000 ft/lbs with no success, so they continued jarring for the next 10 hours.
The team decided to pump and soak the well with deep clean pills. While working the string, they finally managed to get it free.
Finally, having the DRD in the string, the client executed all desired contingency plans to free the drilling BHA. We managed the full operations safely with zero incidents and completed the job successfully.
- We saved the client 34 hours of dedicated WBCU operations with an approximate value of $375,000.
- During the 10+hours of jarring operations, the DRD scraper remained in dormant mode.
- The DrillRdillo Expandable Scraper returned to the surface in good condition.
- The DrillRdillo offers clients an expandable casing scraper that does not limit their drilling operations even in the harshest conditions.

Odfjell Well Services (OWS) is expanding its Thread Repair portfolio at the Repair Workshop Facility in Eastern Europe. Recently, we have been licensed by NOV Grant Prideco to execute premium threading.
Different methods and technology for reducing the number of well trips have been around for some years; however, as a result of the latest market down-cycle period, these approaches have gained fresh interest, creating a new wave of development in technology-based solutions. In this article I will go into further detail about three of Odfjell Well Services' main technologies on how to reduce tripping.
With the BHA hanging from a hang-off plate during three nautical miles of rig sailing, Equinor and Baker Hughes managed to drill eight top holes on two different templates way ahead of schedule.
In the current climate of lower oil prices, getting to total depth cheaper and faster is paramount. Companies are pushing the limits utilizing the latest drilling tools that drill faster; provide instantaneous corrections when steering; have more accurate logging; and overcome what was previously considered “un-drillable” wells.
Odfjell Well Services’ DrillRdillo™ Multi-Application Scraper was recently mobilized to Cameroon. Through the use of a combined drilling and wellbore cleanout BHA, the IOC was able to drill out a bridge plug, cement plugs and complete a wellbore clean-up in one trip.
The DrillRdillo from OWS has saved trips for clients from Myanmar to Angola; from The Middle-East to The North Sea. Here we present you with a quick overview of some stats and use cases from clients utilising the tool for a variety of applications.
Both equipment and competence were put to the ultimate test when Odfjell Well Services faced their heaviest casing string in Romania so far. Petrom – OMV subcontracted Rig Saipem 5870 was going to set 13 5/8” 14” Casing (535 Tones / 3801m) in the Baicoi field in Romania.
I often get requests for different tools from the end users, but they are almost never aware of the tool condition on delivery. A little attention to such an important detail could prevent trouble later. And it could be decisive for choosing the right service supplier. The lowest price and cost is always attractive, but do you know the condition of the tool you are about to run in the hole?
