A deep dive into the value of wellbore clean-ups

No matter the type of well, the proper cleaning of the wellbore is a vital stage to ensure a successful project. A poorly cleaned wellbore can cause damage to downhole equipment, cause production losses, and damage the formation. That’s why our Oilfield Product and Business Development Manager at Shrieve, Andy Moffat, has taken a deep dive into why you should properly clean your wellbore before production begins.


It’s all in the preparation

An effective wellbore clean-out trip should be a key step included in any well construction: After the massive investment of time, money, and effort to drill the hole intervals to reach the reservoir target, the final stage, of preparing the well for the completion & production phase, should be a wellbore clean out trip to remove any mud residue, swarf, drill cuttings and other debris from the wellbore (such a tie-wraps, tape, pipe dope etc). The long-term sustained production of a well is dependent on this step being accomplished properly.


Time is money

Debris left within the casing and liner of a well poses a significant risk to your well performance and its completion activity. Failure to clean the wellbore increases the risk of creating non-productive time in the long run, which will then create increased remedial costs for your company. By investing in a clean wellbore from the outset, you increase productivity and reduce the likelihood of premature equipment failure and expensive downtime later.


It helps productivity and longevity

Wellbore debris is a recurrent problem in drilling operations: In addition to the mud components and drilled formation being transported up the annulus, there can be other potential hazards: Metallic swarf is generated by drillstring rotation, and other obstacles can impact on operations going forward; pieces of float equipment may not have been drilled out entirely from the shoe track, and other unscheduled events can introduce fallen and dropped objects into the well (such as tong dies, gloves, handtools etc- that conventional circulation does not remove). Running a wellbore cleanout string and pumping a wellbore clean out pill train provides an opportunity to both retrieve debris, and to confirm that the next operation (usually running the completion assemblies) can proceed with high confidence for a successful trip in hole. Wells differ greatly in geometry, offset and measured depth, but the outcomes of leaving debris downhole can be summed up simply as bad practice.

 Investing in a clean-up in advance of the completion phase can protect your well, assuring that your wellbore maintains its integrity and improves production life span.
