Superior Gauge Protection
Extended gauge pad with multiple rows of PDC and diamond-enhanced cutters ensures full-gauge hole from surface to total depth on every pass.
Ledge Removal
Aggressive shoulder and gauge cutting structures efficiently remove ledges and tight spots that can cause problems during casing running operations.
Wellbore Conditioning
Specialized blade geometry conditions the wellbore by smoothing irregularities and removing filter cake buildup for improved cement bond quality.
Dual-Purpose Design
Effective both as a dedicated wiper trip tool and as a drilling bit with enhanced gauge protection for problematic hole sections.

Application Areas
Pre-Casing Conditioning
Essential tool for conditioning the wellbore before casing running operations, removing tight spots and ensuring smooth casing descent to target depth.
Pre-Logging Trips
Creates a clean, full-gauge wellbore for wireline and LWD logging operations, ensuring unrestricted tool passage and accurate data acquisition.
Cement Job Preparation
Removes filter cake and smooths the wellbore wall to promote better cement bonding and more effective zonal isolation in completion operations.
Problematic Hole Sections
Addresses undergauge sections, swelling shales, and other borehole instability issues that threaten well construction integrity.

WiperTrip (WT): Ensuring Wellbore Quality for Flawless Operations
Wellbore conditioning is a critical but often underappreciated step in well construction. Ledges, tight spots, undergauge sections, and filter cake buildup can all cause problems during subsequent casing running, cementing, and completion operations. The WiperTrip (WT) PDC bit series from VBM is specifically engineered to address these challenges, providing drilling teams with a reliable tool for achieving the cleanest possible wellbore.
The defining feature of the WiperTrip design is its extended gauge pad, which can be up to twice the length of standard PDC bit gauge sections. This extended gauge area is populated with multiple rows of PDC cutters and diamond-enhanced elements that aggressively trim the wellbore to full gauge while smoothing out irregularities. The result is a uniform borehole that allows casing to be run smoothly to target depth without the costly delays associated with tight spots and ledges.
In addition to mechanical wellbore conditioning, the WT series also contributes to improved cement job quality. By removing drilling fluid filter cake and smoothing the wellbore wall, these bits create a surface that promotes better cement bonding. This is particularly important in wells where zonal isolation is critical, such as production wells in the oil and gas industry and injection wells where maintaining wellbore integrity is essential.
VBM Middle East provides the complete WiperTrip (WT) product line for drilling operations across the Gulf region. Our technical team works with operators and drilling contractors to identify wellbore conditioning requirements and recommend the appropriate WT configuration for each application.
