PDC Drill Bits for Guyana

Volga Burmash polycrystalline diamond compact bits in steel-body and matrix-body designs for vertical, directional and horizontal oil and gas wells, in soft to medium formations including those with hard interlayers. Six lines cover full-hole drilling, reaming, open-hole sidetracking, underreaming while drilling and coring, from 83.0 mm (3 9/32") to 444.5 mm (17 1/2").

Product Lines

Six Volga Burmash PDC families cover the full offshore bit programme — from general-purpose drilling and abrasive-interval protection to sidetracks, hole opening and coring. Each line is matched to formation, hole size and BHA so every section drills to plan.

FD

FastDrill (FD)

The all-purpose steel-body PDC line for full-hole drilling of vertical, directional and horizontal oil and gas wells. The cutter layout is designed with BitScan software, and flushing through open channels at the bottom cleans the hole bottom. Available with 3 to 9 blades and 8–19 mm cutters, in sizes from 83.0 mm (3 9/32") to 444.5 mm (17 1/2").

  • Body: Steel
  • Blades: 3 to 9
  • Cutters: 8 to 19 mm PDC
  • Application: Vertical, directional and horizontal drilling
FDM

FastDrillMatrix (FDM)

The matrix-body counterpart of the FastDrill series, also designed with BitScan software. The matrix body provides high abrasion and erosion wear resistance; sizes from 149.2 mm (5 7/8") to 311.1 mm (12 1/4") for medium formations, including those with hard interlayers.

  • Body: Matrix
  • Blades: 5 to 7
  • Cutters: 13, 16 and 19 mm PDC
  • Application: Abrasive formations
WT

WiperTrip (WT)

Steel-body PDC bits for hole reaming and gauging (wiper trips). The parabolic profile prevents spontaneous sidetracking. Sizes from 117.5 mm (4 5/8") to 220.7 mm (8 11/16").

  • Body: Steel
  • Blades: 4 to 6
  • Cutters: 9 mm and 13 mm PDC
  • Application: Hole reaming and gauging, wiper trips
ST

SideTrack (ST)

PDC bits designed for open-hole sidetracking, providing fast execution of operations. Sizes from 124.0 mm (4 7/8") to 295.3 mm (11 5/8").

  • Blades: 6 to 9
  • Cutters: 10 mm and 13 mm PDC
  • Application: Open-hole sidetracking
BD

BicentricDrill (BD)

Eccentric PDC bits that drill a hole larger than the nominal bit diameter using a bicentric (under-reamer) design, for underreaming while drilling: the pilot section drills the drift-size hole while the eccentric section enlarges it to the opening size (for example 215.9 x 250.8 mm) in one pass. Drift sizes from 120.6 mm to 311.1 mm.

  • Body: Steel
  • Design: Bicentric / eccentric
  • Cutters: 13 mm and 16 mm PDC (5 to 7 blades)
  • Application: Underreaming while drilling
CB

CoreBits (CB)

Steel-body PDC core bits for core drilling and formation evaluation. They cut an annular ring around a central core, preserving an intact cylindrical rock sample for laboratory analysis. Bit sizes from 139.7 mm (5 1/2") to 295.3 mm (11 5/8") cut cores of 52 to 100 mm.

  • Body: Steel
  • Cutters: 9 mm and 13 mm PDC (6 to 10 blades)
  • Core sizes: 52–100 mm
  • Application: Coring, formation evaluation

Catalogue Feature All-purpose full-hole drilling (FD) High abrasion and erosion wear resistance
Field Application

PDC Bits for Guyana Offshore Drilling

How the six lines map onto real work in the Stabroek Block and the wider Guyana-Suriname basin — from deepwater long laterals to abrasive intervals, sidetracks and formation evaluation.

Long LateralsStabroek deepwater horizontals

The long horizontal sections that maximize reservoir contact in deepwater Stabroek wells demand high ROP and predictable steering. Steel-body FastDrill bits are designed for full-hole drilling of vertical, directional and horizontal wells, with BitScan-designed cutter layouts and 3 to 9 blades to match the formation.

Abrasive SandsBody protection that lasts

Where drilling fluid carries abrasive sand, the matrix-body FastDrillMatrix is the choice: its matrix body provides high abrasion and erosion wear resistance, in sizes from 149.2 mm to 311.1 mm.

SidetracksRe-drills & hole opening

For open-hole sidetracking, SideTrack (ST) bits provide fast execution of operations. When a section needs underreaming while drilling, BicentricDrill (BD) enlarges the drift-size hole to the opening size in the same run — saving rig time on costly deepwater days.

CoringFormation evaluation

When the well programme calls for intact rock for the lab, CoreBits (CB) cut an annular ring and preserve a cylindrical sample. Steel-body PDC core bits from 139.7 mm to 295.3 mm cut cores of 52 to 100 mm in diameter.

When to Run PDC vs Tricone in Guyana

PDC and tricone bits are complementary, not interchangeable. Fixed-cutter PDC bits shine in the soft-to-medium clastics and carbonates of Guyana's offshore upper and intermediate sections, where they can stay in the hole for long, trip-saving intervals. Their lack of moving parts also suits the long motor runs typical of directional and horizontal drilling on the Stabroek Block.

Tricone bits keep the edge in harder, more interbedded or chert-laden formations, in spudding tophole, and wherever shock loading and unpredictable lithology would risk cutter breakage on a PDC. Many Guyana well plans run both — a PDC for the long drillable sections and a tricone bit for the hard stringers and surface hole — selected against offset data rather than habit.

To match a bit to your formation by IADC code and dull-grading history, see our guide on how to choose a drill bit by IADC code, and for the offshore supply picture read drill bits for the Stabroek Block. Or send us your well data and we will spec the run.

Selection guide

Choosing a PDC bit

A PDC bit shears rock with fixed diamond cutters and has no moving parts, so in the right formation it drills longer intervals faster than a tricone.

Where PDC works best

  • Soft to medium, homogeneous formations such as the Tertiary clastics offshore and the sandstones and shales of onshore basins.
  • Long directional and horizontal sections run on downhole motors.
  • Water wells in consolidated sediments without boulders.

In fractured, bouldery or very abrasive rock, a tricone bit remains the safer choice.

Steel body or matrix body

Steel bodies allow tall blades and aggressive profiles. VBM's matrix-body FastDrillMatrix bits offer high abrasion and erosion wear resistance.

The IADC code for PDC bits

Fixed-cutter bits use four characters: body material (S steel, M matrix), cutter density from 1 (25–50%) to 4 (over 90%), cutter size (1 = over 24 mm, 2 = 14–24 mm, 3 = 8–14 mm, 4 = under 8 mm) and profile from 1 (short fishtail) to 4 (long). An S223 is a steel-body bit with 50–75% cutter density, 14–24 mm cutters and a medium profile. VBM does not publish IADC codes for its PDC models; they are identified by blades, cutter size and formation category.

FAQ

PDC drill bit FAQ

What does PDC stand for?

Polycrystalline diamond compact: synthetic diamond tables sintered onto tungsten carbide substrates that cut rock by shearing.

PDC or tricone?

PDC is faster and lasts longer in soft to medium homogeneous formations; tricone is safer in hard, fractured or abrasive rock. Many wells use both, section by section.

Do you have PDC bits in stock?

Yes, FastDrill steel-body bits, mostly 8 1/2". We ship from our Dubai warehouse by air or sea; the exact lead time is confirmed in each quotation.
