Drill Bit Accessories for Guyana
Auxiliaries for Volga Burmash oil and gas drill bits listed in the VBM catalogue — jet nozzles for roller cone and PDC bits, nozzle wrenches and bit breakers — the consumables and handling gear an offshore MRO supply chain needs to run, dress and maintain a Volga Burmash bit on the rig floor. VBM Guyana supplies them as registered MRO and drilling consumables in line with the Local Content Act 2021.
Product Categories
Three accessory families from the VBM oil and gas catalogue — from the jet nozzles that drive your hydraulics to the bit breakers and nozzle wrenches used at make-up and break-out.
Jet Nozzles (Oil & Gas)
Jet nozzles for Volga Burmash oil and gas roller cone and PDC bits. The nozzle sets the velocity and direction of drilling fluid leaving the bit, which matters for bottom-hole cleaning and cuttings transport. Roller cone bits use side nozzles R9531, R6738, R3401, R1804, R0030 or R0101 depending on bit size, with central nozzles R1804 (optional) and R0030 on larger bits; PDC bits use ports (unchangeable nozzles) or replaceable threaded nozzles.
- Orifice sizes 7/32" to 28/32" (depending on nozzle type)
- Roller cone nozzles R9531, R6738, R3401, R1804, R0030, R0101 (by bit size, 104.8–660.4 mm)
- PDC ports 9/32" to 16/32"
- PDC threaded nozzles MJP-CSA-201, AH22-3, AH27-4, AH39-3
Bit Breakers
Bit breakers hold the drill bit while its threaded connection is made up or broken out. The VBM oil and gas catalogue lists seven models, from BB A63,5P-1 to BB A177P-7, with shipping dimensions and weight for each model.
- Models BB A63,5P-1, BB A66P-1, BB A76P-1, BB A88P-1, BB A117.85P-1, BB A152-177P-1, BB A177P-7
- Shipping dimensions 330 x 330 mm to 711 x 711 mm
- Weight 26 kg to 175 kg
Makeup & Breakout Tools
Makeup and breakout accessories listed in the VBM catalogue: bit breakers and nozzle wrenches. The nozzle wrenches are used to install and remove the replaceable threaded nozzles of PDC bits.
- Bit breakers BB A63,5P-1 to BB A177P-7
- Wrench R22561 for MJP-CSA-201 nozzles
- Wrench A22K for AH22-3 and AH27-4 nozzles
- Wrench A39K for AH39-3 nozzles
Why Proper Accessories Matter
The accessory is small next to the bit, but it decides how well that bit drills, how long it lasts and how safely it is run. Get nozzles, breakers and tooling right and every bit on the program performs to its potential.
HydraulicsOptimal hydraulic performance
Nozzle sizing is one of the highest-leverage choices in drilling optimization. The right configuration concentrates hydraulic horsepower at the bit face, lifting cuttings off bottom and pushing rate of penetration. We can run the nozzle calculation against your flow rate and bit so the bore set matches the well.
HandlingSafe bit handling
Bits are precision tools, easily marred by careless handling. The correct breaker and makeup tools keep threads from galling, the body from damage and the cutting structure from impact — and they keep rig crews out of harm's way during a bit change on a moving floor.
ConnectionsConnection integrity
API connections only hold pressure when made up to the right torque with proper thread compound. The VBM catalogue gives recommended make-up torque values for bit thread connections, and the bit breaker holds the bit while this torque is applied.
Service LifeExtended equipment life
Good accessories pay for themselves by stretching the working life of costly bits and subs. Correctly bored nozzles resist premature erosion, matched breakers spare the body, and disciplined thread care lets a connection take many makeups before it degrades.
Jet Nozzle Reference
A quick look at common orifice sizes across the 7/32" to 28/32" range. Specify the nozzle type, the size in 32nds of an inch and the quantity per size when you order.
| Nozzle Size (1/32") | Bore (in) | Typical Use |
|---|---|---|
| 8/32 | 0.250 | Small-diameter and slim-hole bits, higher jet velocity |
| 11/32 | 0.344 | Intermediate sections balancing velocity and flow area |
| 14/32 | 0.438 | General-purpose oilfield drilling, mid-range hydraulics |
| 18/32 | 0.563 | Larger holes with high flow rates and heavy cuttings load |
| 24/32 | 0.750 | Big-bore surface and conductor sections, low pressure drop |
| 28/32 | 0.875 | Largest orifice listed (R0030 and R0101 roller cone nozzles) |
Consumables for Guyana's Offshore Supply Chain
An offshore drilling program lives or dies on the small parts. The crew needs the right nozzle bore in the rack before the bit goes in the hole, a breaker that matches every size on the program, and clean, greased threads each time a connection is made up. VBM Guyana supplies these as registered MRO and drilling consumables, positioned to support the Stabroek Block supply chain under the Local Content Act 2021 framework — so operators and tier-1 service companies can source nozzles, breakers and wrenches through one authorized distributor, with bit breakers held in stock in Dubai.
Order accessories on their own or bundled with a bit purchase. We recommend stocking a full set of nozzles in your most-used bores together with a matching breaker for each bit size you run, so the right part is always at the rig when it is needed. For the bits themselves see our tricone bits; carbide parts made on request are listed under carbide products.
