PRODUCT OVERVIEW

NEXT-GENERATION (NXG) SOLUTIONS FOR THE OIL AND GAS INDUSTRY

MULTI ACTIVATION CIRCULATION SUB

- An innovative internal mechanism allows flow ports in the outer body to be opened and closed from the surface, simply via the operation of the mud pump controls by drilling personnel.

- Upon activation, a shut-off mechanism closes the tool inner bore, allowing lost circulation material to be pumped out through the side ports. It means MWD and LWD equipment located below the tool are protected – at all times.

Our Multi Activation Circulation Sub has been designed not only to overcome the most complex circulation challenges – but to do so with optimum efficiency and total reliability as part of your bottom hole assembly. It is a breakthrough technology: one that eliminates unnecessary rig downtime to save you time and money.

OILSCO Technologies’ Multi Activation Circulation Sub - it is a breakthrough technology.

- Our Multi Activation Circulation Sub bypasses the need to break the drill string as part of the process: no ‘ball’ or ‘dart’ devices required.

- It can be activated (opened or closed) as many times as you require during an individual drilling operation.

- Its activation/deactivation status – whether open or closed – can be instantly gauged on the drill floor.

HOLE CLEANING DRILL PIPE

- Hole cleaning via stirring up cuttings beds from the low side of the wellbore.

- Reduced wall contact also lessens the risk of differential sticking – a key issue in depleted formations.

- The unique design supports sliding in high angle hole and horizontal sections, by reducing contact areas typically experienced on long sections of standard HCDP. Drag is reduced significantly, allowing directional control with less weight stacking on the bit.

A next-generation product that will give you an operational edge, it’s the result of painstaking research, design and development work by industry innovators. Our pioneering HCDP delivers significant reductions in torque and drag because of both its hole cleaning capabilities and reduced wall contact in the critical bottom hole assembly area.

OILSCO Technologies’ Hole Cleaning Drill Pipe is anything but standard.

HCDP SpecificationsThis drill pipe can be manufactured to replicate the same weights and dimensions asstandard and premium heavy weight or drill pipe.

- An ideal solution for ERD wells where torque build-up can restrict the high rotation required to aid hole cleaning.

- Reduces the requirement for additional connections while benefitting from the hole cleaning technology, standard stand lengths are still maintained.

A

Heavy-weight or Light-weight Drill PipeThis HCDP comes in 2 versions either as a heavy weight which would be placed in the BHA or as a light weight which would be strategically placed in the drill string to assist in cleaning problem areas such as the inclination build up within a section.

NOT FOR MANUFACTURE

HOLE CLEANING SUB

- A patented pending unique impeller/spade design for maximum cuttings agitation.

- Industry standard Arnco 350XT hard banding application.

A durable tool that is located between sections of drill pipe to redistribute cuttings that settle out of the mud on the low side of the wellbore, it comes into its own in highly deviated sections – in excess of 40°– where the build-up of cuttings beds is often most acute.

CFD analysis has already shown that its innovative design is capable of delivering a clear increase in cuttings removal, over longer periods, compared to a drill string without any mechanical aid.

Our Hole Cleaning Sub is a perfect example of OILSCO’s ideas in action – to benefit your drilling operations.

DRILLING REAMER

- Due to their domed geometry our Diamond Insert allows for increased reaming capability with gauge protection & stabilization properties. The inserts are strategically placed within the blade which assists with the removal of dog legs and ledges during drilling operations. The inclusion of our diamond technology within the drilling reamer dramatically reduces repair charges and increases the lifespan of the Drilling Reamer.

- Using our unique brazing process there are no temperature limitations during drilling operations.

Designed to complement the attributes of Roller Reamers and stabilizationequipment, Our Drilling Reamer has approx 70-80% less wall contact thanstandard stabilization equipment currently used within the drill string.

Our Drilling Reamer is designed for ease of use and built to be durable.

Drilling Reamer Specifications (all sizes in inches unless otherwise specified)

- The diamonds are fully impregnated which means they have greater wear resistance properties without limited lifespan of PDC inserts.

- The Drilling Reamer has no moving parts eliminating issues caused by the loss of in the hole i.e roller reamer cartridges.

- The OILSCO Technologies Drilling Reamer is available in gauge sizes from 6” to 26”.

- The drilling reamer has no moving parts eliminating the risk of lost in hole of standard reamers and also the need to trip out of hole on cutter revolutions.

Additional SizesOther sizes and combinations are available on request (including extended body lengths).

DEVELOPED TO OVERCOME THE TOUGHEST HOLE CLEANING CHALLENGES

TRI-TORNADO SINGLE-STAGE HOLE OPENER

Features

- Smooth transition on body OD

- Spiral skirt blades and pilot blades

- Offset Cutters

- Unitized saddles

- Reinforced hardfacing on vulnerable areas

- Available in various sizes

Benefits

- Cost-effective to manufacture and therefore competitive hole opener

to run

Our Hole Opener boasts a series of features that underpins its performance:

- Maintaining smooth OD along the length of the body reduces chances of cutting build up and packing off

- Spiral skirt blades encourage directional flow and removal of cuttings

- Spiral pilot blades promote turbulent flow and hole cleaning

- Cutters positioned in an offset manner ensuring a more aggressive cutting effect

- Unitized saddles provide for easy replacement and can accommodate various cutter types

- Strategically placed upward nozzles encourage flow and ensure cutters stay free of debris

The smooth transition on the body OD reduces the chances of debris build upand packing off. The spiral body blades and pilot blades encourage directiona/turbulent flow, removal of cuttings/debris and excellent hole cleaning.

This unique hole opener has offset positioned cutters to allow a more aggressivecutting effect and strategically placed upward facing nozzles to encourage flowand ensure the cutters stay free of debris. The nozzles are held in retainers andare not machined as part of the integral body, enabling easy replacement andpreventing body damage from washing.

SEALED BEARING ROLLER REAMER

- The cartridges are pressure equalised and the sealed design prevents ingress of drilling mud and cuttings whilst maintaining grease inside the cartridge – all serving to significantly extend bearing life.

- The cartridge design and retention method’s capacity to extend bearing life, means more revolutions are possible before redress of the roller.

Serving to reduce torque, improve bit performance and extend the operational life of bottom hole assembly components, it boasts a series of attributes that place it at the cutting edge of its specialist arena:

Our Sealed Bearing Roller Reamer is designed for ease of use and built to be durable.

- The high temperature seals and grease that complement the cartridges are rated to 210°C.

- The cartridge is a one-piece assembly meaning redress of the tool is simple and reliable.

- The roller is bi-directional to allow back reaming at all times.

- The OILSCO Technologies Roller Reamer is available in gauge sizes from 5⅞ to 28.
