APS provides many exciting new drilling optimization and vibration management products in our SureDrill family. These hardware and software products share a common goal of allowing end users to drill smarter and faster by:
With a combination of autonomous vibration mitigation and real-time and recorded drilling data analysis, APS offers technologies that help accurately predict and measure the variables that impact the drilling process, allowing end users to meet or exceed their drilling plan.
Active Vibration Damper
APS’s Active Vibration Damper (AVD) is a standalone downhole tool that autonomously adapts to changing downhole BHA motion in real time to minimize axial, lateral and torsional drill string vibration. The AVD has demonstrated 50% improvements in rate of penetration (ROP) and doubling of bit life in the field due to reduced vibration. Other downhole drill string components, like MWD / LWD tools, also benefit from lower vibration.
Structurally, the AVD is similar to a shock-sub, with the addition of a damper section that has programmable stiffness. The damper chamber is filled with a magnetorheological fluid that has electronically controlled viscosity. An integrated motion sensor measures displacement several times per second and changes the damping factor over a 7-to-1 range based on observed drilling conditions.
By keeping tool string damping in the right range for current drilling conditions, the AVD significantly reduces vibration, maintaining the bit in better contact with the formation and increasing ROP.
FEATURES & BENEFITS
1.Vibration reduction
2.Stick Slip remedial
3.Improved ROP
4.Longer Bit Life
5.Reduced NPT
6.Self-contained drilling tool with no calibration or other rig maintenance required
7.Records vibration data for later download

Case Study
Challenge
In this typical Barnett shale well, Beacon E&P required multiple bit trips to drill the tangent section through the Hard Atoka Sandstone.
Solution
APS Technology recommendation was to run the AVD on one well and confirm that the improvements seen on the drilling results were linked to the reduction in drilling vibration by running the VMS (Vibration Monitoring Sensor) on an offset well.
Results
The well where the AVD was run was drilled with fewer bit trips and a higher ROP. The savings averaged one and half days to the operator compared to offset wells. The tangent was drilled in 4 days. VIBRATION CONTROL BRINGS 20% IMPROVEMENT IN DRILLING EFFICIENCY.
Downhole Drilling Dynamics Monitor
APS’s Drilling Dynamics Monitor (DDM) sub measures and records weight on bit, torque on bit, bending on bit, internal and annular pressure and temperature during drilling operations.
FEATURES & BENEFITS
Captured data may be transmitted in real time via APS’s SureShot MWD/LWD system, or stored in the DDM’s downhole memory for later download and analysis.
Can be equipped with vibration monitoring to measure, calculate and record axial, lateral and angular downhole shock and vibration.
Real-time vibration alarms may be transmitted via SureShot.
Vibration Memory Sub for Drilling Optimization
The SureDrill Vibration Memory Sub (VMS) is a standalone downhole tool that measures, calculates and records axial, lateral and angular down-hole vibrations for retrieval and analysis at the surface. The VMS allows operators to assess the severity of downhole drilling shock and vibration, including stick-slip and whirl, and correlate the data to drilling events and equipment performance or failures.
Calculated Vibration Data
Every 20 seconds, the microprocessor calculates and stores:
Maximum lateral acceleration – vector sum of X- and Y-accelerometer measurements
RMS lateral acceleration
Maximum half-second RMS lateral acceleration
Maximum axial vibration – from z-accelerometer
RMS axial acceleration
Maximum half-second RMS axial acceleration
Maximum and minimum angular speed (RPM)
Stick-slip ratio and other rotational parameters
Absolute date and time
FEATURES & BENEFITS
Downhole vibration measurements are stamped by date and time for correlation with other data.
Provides data in the form of ASCII text files which can analyzed by APS’s Vibration Data Viewer software or your own analysis software.
32 MB of memory; record up to ~250 hours of continuous data.
Data is easily retrieved by accessing the data dump port on the sub and connecting it through an Interface Box to PC-based software that converts the stored data to a text file with acceleration levels as a function of real time.
Sonde-based tool with standard box and pin connections.
Sonde-based design allows tool to be scaled up or down easily for use with other drill collar sizes.
Vibration measurements are made using ± 120 g (lateral) and ± 60 g (axial) accelerometers, plus one fluxgate magnetometer rotation sensor.
Downhole Drilling Optimization Software
APS Technology now offers a suite of drilling optimization applications that helps operators and drilling companies save time and money on well construction and operation. We are the only mid-sized provider to offer a comprehensive well drilling optimization solution, the industry-leading SureDrill-Optimizer system. SureDrill-Optimizer is a drilling optimization service that combines:
Drill string modeling and analysis (pre-well and real time)
Drilling optimization based on real-time surface and downhole data
Pre-well offset analysis of previously drilled wells – can identify known drilling issues and select the best drilling setpoints for each formation
Post-well analysis
SureDrill-Optimizer can be set up either as an on-site service or as a remote service. As a remote service, the data is transmitted back to a technology center or customer’s office. For wells drilled in new regions, where there is little or no history, SureDrill-Optimizer quickly identifies the best drilling practices. SureDrill-Optimizer helps avoid and mitigate drilling dysfunction that can lead to unplanned trips.
SureDrill Optimizer – Real-time well drilling optimization service
APS is the only mid-sized provider to offer a comprehensive well drilling optimization solution: the industry-leading SureDrill-Optimizer system. Optimizer combines drillstring modeling with real-time surface and downhole drilling data to optimize drilling parameters, maximizing ROP, extending bit runs and resulting in lower drilling costs. This system provides:
FEATURES & BENEFITS
1.Increased ROP
2.Reduced vibration
3.Increased bit life
4.Longer bit runs
5.Reduced bit trips
ROP increases up to 70% have been achieved on several wells. Optimizer identifies drilling dysfunctions early so the driller can take corrective action and avoid unplanned trips.
