Coretrax Churchill Darts For The Oil & Gas Industry

Drift Catcher™ - Volumetric Drift

Allows the drifting process to simultaneously gauge the pipe volume. In certain string/liner volume ratios there may be a high risk of over displacement especially if non-bumping plugs are run.

Drift Catcher™ - Choked Drift

Used in hundreds of wells, this drift is perfectly designed to reduce dropped object risk and give a confirmed and accurate drifting process.

DAV MX™ - Alternative Diverter Dart

Shorter than the Standard Diverter Dart, this dart allows the valve to close with the pumps off, closing off the annulus.

DAV MX™ - Emergency Shut-Off Dart

Not only does the DAV MX™ push the operating envelope further and have the best reliability in class, it also provides a totally unique back-up closing system.

DAV MX™ - Split Flow Dart

The best method for DAV MX™ hole cleaning, by delivering some flow to the bit also in a hold-open mode.

DAV MX™ - Standard Diverter Dart

The standard method for DAV MX™ bypass, delivering 100% BHA bypass with in a hold-open mode.

DAV MX™ - Ultra Series

The Ultra Series Dart is capable of high speed activation, allowing it to be pumped in at up to 400gpm which is ideal for ERD (Extended Reach Drilling).

DAV MX™ - Universal Closing Dart

Whichever opening dart is used the Universal Closing Dart will shear it out to close the DAV, with both darts landing in the catcher below.

HyPR™ - Cementing Dart

When time is at a premium the cementing dart will give immediate side-tracking in a stuck pipe situation.

HyPR™ - Fishing Dart

When attempting to fish the BHA is preferred, this dart leaves a clear unrestricted access to the fish after it has cut the string free.

Pressure Test Sub - Pressure Test Dart

With a simple landing sub and catcher installed in the string Pressure Test Darts can be dropped in to pressure up the string above and test its integrity.

Self Filling Float - Float Activation Dart

The smallest and simplest dart in the range, ergonomically designed to pass through all of the upper string and drop into the dormant float sub and shear it into activation.

Offering 12 different string configurations

Churchill Darts offer 12 different string configurations across 5 different products, enabling you to take advantage of a whole host of performance advantages:

Fast and Economical:

All the extra simplicity and performance saves lots of rig time, and with no service hand and very simple subs deployed, dart activated systems are extremely economical and cost effective.

High Angle & HPHT:

Designed to perform in almost any environment with features like robust metal shoulders and brass shear pins, darts have extremely high load tolerance and deliver very consistent shearing across the full down-hole temperature and pressure range. Darts are completely user operable even in extreme wells, with simple and standard drop and pump methodology.

Smart Darts & Simple Subs:

Darts, securely stored at surface and pumped into a sub are the perfect solution to deliver flexibility and reliability. Down-hole operating longevity comes from robust, simple, well designed subs with maximum environmental resilience. The single-use darts are only exposed to the well for a few minutes before they land and deliver the required configuration.

Plug and Play Ease & Flexibility:

Users simply select the dart to match their application and pump it into place. A clear pressure indication is seen instantly at surface to facilitate a quick move onto the next program phase.

Mechanical Broadband:

No other mechanical activation method can deliver more different devices in a string. The dart shoulder to seat interference is around a millimeter, meaning that our tool designers are able to deliver serial tool positioning with little loss of internal diameter from one tool to the next. Up to three different tools can share a single catcher and be operated in any order multiple times. Many multiples of these can be deployed with a “lowest first” approach.
