For maximum performance and durability, our modules are made from individually forged, heat-treated alloy steel and feature an API 7 valve assembly for improved flow. Our L-shaped design features bore-seal technology for improved seal performance in higher pressures and is compatible with numerous “F-Series” drilling pumps including Honghua®, Bomco® Rongsheng®, Workforce® and other similar designs.

Developed using decades of drilling expertise and field proven performance, GD Energy Products’ Y-Shaped drilling module builds on our legacy of delivering innovative solutions. Featuring a unique bore geometry, our Y-Shaped module is designed to provide maximum performance and reliability. The module’s two-piece design simplifies routine maintenance and reduces total cost of ownership.

Our patented internal bore geometry features an API 7 valve assembly to allow fluid to flow smoothly through the module, providing maximum efficiency. The compact vertical dimensions minimize the percentage of un-swept, or “dead”, volume in the module, further maximizing efficiency.

GD Energy Products’ Y-Shaped module is engineered to provide unrivalled reliability. The unique design reduces the stress placed on the module’s cross-bore intersection, maximizing service life and reducing the risk of cavitation. Constructed from premium, heat-treated forgings ensures that our module can withstand the highest pressures, in even the most demanding conditions.

The module’s two piece construction and ergonomic, forward leaning orientation work to streamline maintenance. Compatibility with a range of standard GD Energy Products module hardware ensures that parts and spares are available, whenever and wherever you need them.

Mud Pump Fluid End Module is forged by high-quality alloy steel 35CrMo or 40CrMnMo. It has no defects such as interlayer, crack, impurity, looseness and over-burning. Welding is not allowed. The Mud Pump Fluid End Module is in full compliance with API7K standard and is inspected according to the third-grade forging and internal hardening treatment, high durability. Above process is strictly checked and strict non-destructive testing.

An expendable needs to be dependable until its replacement. This is the very essence of the approach at ShalePumps towards all components, classified as expendables in Oil Exploration and Production. Mud Pump Fluid End Modules are absolutely vital to the operations of a Mud Pump. Machined from the highest quality of forged material, the fluid end modules have a very high threshold for cracking. This lends the fluid end modules longer life which in turn has a positive effect on overall operations.

All fluid end modules that leave the plant at ShalePumps got through a battery of tests that include hydrostatic testing. With assured integrity of the materials that go into all fluid end modules, the mud pumps can be operated with greater confidence.

The residual stress testing procedures are rigorous and translate into steady performance under exerted pressure in operations. All fluid end modules that go into the mud pumps are tested through scientifically proven fabrication techniques. Part of the reason why our expendables are always dependable till the extended duty cycle comes to the end of its operational life.

Deploying an embedded system with that could be retrofitted onto existing pumps, to monitor and analyze mud pump vibrations. helped reduce human exposure to hazardous environments.

As an integral part of onshore and offshore drilling, mud pumps circulate drilling fluids to facilitate drilling oil and natural gas wells. Mud pumps stabilize pressure and support the well during the drilling process and drilling fluids provide friction reduction and a means to remove cuttings. We created a leak detection system for hex pumps. The hex mud pump (see Figure 1) has six pistons, six suction valves, and six discharge valves. The six pistons are driven by a rotating, asymmetric cam. We designed a patented leakage system based on CompactRIO in house. The system monitors the suction and discharge valves using accelerometers.

The Case for an Automated Monitoring SystemValve leaks in piston pumps are often discovered at a late stage when the leaks are so severe that they induce large discharge pressure fluctuations and create washout damages. When a severe leak is detected, we localize it manually by listening to the fluid modules while the pump is running, but it is difficult to uniquely localize the leak and distinguish between a suction valve leak and a discharge valve leak.

Human exposure to hazards is the main disadvantage of manual detection, verification, and localization. Mud pumps convert large amounts of power and often output high pressures up to 350 Bar discharge. Additional equipment in pump rooms also generates high acoustic noise pressure levels that can exceed 100 dBA and cause health and hearing damage if humans are not correctly protected (see Figure 2).

Discovering the Vibration MethodDuring a vibration monitoring project for hex pumps, we discovered the possibility of detecting leaks using accelerometers. We recorded vibrations at different locations, both on the pump and on the discharge line, along with suction pressure, discharge pressure, and pump speeds for different pump conditions. We used a 20 kHz sampling frequency and recorded 5-second snapshots with intervals of a few minutes. On one occasion, the vibration signature significantly changed during a 15 minute period. We soon realized the spot was a growing valve leak.

Leak Detection SystemBased on that encouraging experience, we wanted to include this condition-based maintenance system as a standard feature on all hex pumps. We developed the system as a stand-alone module to add to the existing hex pump control system (see Figure 4). Slightly simplified, it consists of the following components: accelerometers (one per valve block), a proximity sensor picking up pump speed and phase, a discharge pressure sensor, an embedded monitoring system (CompactRIO with NI 9234 acquisition modules for powering the accelerometers and acquiring high frequency data), signal processing software and alarm logics implemented using LabVIEW software running on the CompactRIO monitoring system, and an HMI user interface developed in LabVIEW.

The default sampling frequency of the signals is 25 kHz, but the system can handle higher rates if necessary. The bandpass filter is optional, but experience shows that it improves contrast and detection sensitivity. Signal strength normalization by the median vibration level makes the detection nearly independent of the inherent ambient vibrations, which increase rapidly with increasing pump speed and discharge pressure. The last requirement, that the detected leaks last for a set time, eliminates erratic alarms caused by debris or large particles that can cause temporary seal malfunction.

Figure 5 shows a 1.5 second snapshot of the vibration signatures after a severe leak developed in the D3 valve. It shows the filtered vibration signals from all six accelerometers during a 1.5 second snapshot. Acceleration signal 3 has enhanced noise amplitude during the D3 phase. A closer look at the other signals reveals that the leak induced vibrations are transferred to the other accelerometers during the same time intervals. However, the vibration transfer is relatively low, actually less that -20 dB for neighboring valve blocks and even less for the other blocks, so vibration transfer is not a serious problem in hex pumps.

CompactRIO and LabVIEW proved to be fast tools for prototyping our system and gave us an embedded deployment system that we can reliably retrofit to existing pumps. In comparison to other leak detection methods, which are based on analyzing discharge pressure, we found our vibration-based methods to be more robust and reliable, especially when it comes to localizing a leak. Our studies show that an alternative method can be applied for shaft-driven piston pumps having either an integrated valve block or split blocks with a high vibration transfer. Leak localization for this kind of pump is mainly based on the phase of the pulsating vibration level. We can use it to localize one dominating leaky valve at a time.
