Horizontal Directional Drilling (HDD) is a trenchless method for installing pipes and cables underground. The process involves boring a tunnel beneath the surface where trenching is not practical.
Boring underground requires drilling fluid that combines water and bentonite clay to help remove cuttings, stabilize the bore, cool the cutting tools, and lubricate pipe string. As the process comes to life, the drilling pump rotates the drill bit which then removes the material. As the drill bit is rotating, the pressure and fluid produced by the drill pump helps stabilize the tunnel. The mud extracted from this process is then filtered and reused for drilling fluid.
HDD is a process usually deployed when installing pipes and cables underneath roads, rivers and other types of infrastructure. Therefore, most jobs come with a challenging set of parameters that demand high rates of accuracy, efficiency, and effectiveness. Equipment manufacturers and end-users can trust our +160 years of experience manufacturing pumps for both petroleum and industrial industries.

LEC mud pumps use hydraulic power to convert hydraulic energy into the power that can convey high pressure mud. It’s self-suction plunger pump. The parts without rotation make piston linear motion.
•High reliability: no rotating parts, less moving parts, longer free maintenance time, high abrasive resistance and self-lubricating ability, which decrease the operating cost. When the hydraulic power less than max. rated power, the pump will decrease the output power automatically thus make the pump safe.

Mud pump manufacturers frequently offer both types of pumps. In reality, the pump power end and fluid ends are identical. The difference lies with the method used by the pump to displace the mud.
In the early 1990s, it was generally accepted that the pumps used on mid-size and small boring machines should deliver fluid to the bore at a high pressure (1,800 to 2,200 psi/124 to 152 bar)) and have a low flow rate of 5 to 25 gpm (19 to 95 Lpm).
As the industry matured and operators became more experienced, it was found that a higher mud flow with lower pressures was the superior way to bore. In some formations high pressure, low flow is still preferred and provides the most success. However, in the majority of areas, higher flows are best to provide hole cleaning (removal of solids) and provide adequate bentonite for formation sealing and lubrication.
Plunger and packing technology is used when high (800 to 1,000 psi/55 to 69 bar and higher) pressures and lower flows are required. The flow pressure pushes on the front of the packing, compressing it tightly around the smooth surface of the reciprocating plunger sealing off leakage. When the pressure is below 800 to 1,000 psi (55 to 69 bar), there is insufficient flow pressure to assist in this sealing and packing leakage occurs. Leakage carries with it sand and other abrasive solids that lodge between the packing rings and plungers, causing rapid wear to the plunger surface and/or packing and making a good seal impossible.
One advantage of plungers/packing is that the packing can be adjusted by the operator to minimize leakage until the bore is complete and the pump can be serviced.
Pumps with piston/liner technology work in the opposite manner. Pistons work well to prevent leakage when flow pressures are low (below 1,200 psi/83 bar). Pistons are generally larger in diameter than plungers, allowing the pump to run slower-this is good-for the same flow rates.
Pistons have two disadvantages. First, when they fail or start leaking, the operator can do nothing to prolong operation until repairs can be made. Thus, repairs usually have to be made shortly after significant leakage starts. Second, pistons like to run cool and be lubricated. Thus, a piston cooling/lubrication system must be employed to add to piston life.
This system consists of a small centrifugal pump, spray nozzles, piping and collection tank. It sprays a mixture of water and lubricant (non-foaming soap or a small amount of liquid polymer), onto the back of the pistons.
Many boring machines are equipped with plunger pumps. These units are being applied where piston technology should be used, mainly low pressure and higher flows. These pumps frequently have leakage problems. To help operators combat leakage on these boring machines, conversion kits are being developed by some pump manufacturers to allow pumps to be changed from plunger to piston technology. Consult your boring machine or pump manufacturer for availability.
Economically, a good time to consider changing from plunger to piston technology on your pump is when the plungers are no longer serviceable and must be replaced. Conversion kits can be installed in the field and are considered bolt off bolt on upgrades.
If your mud pump has leakage problems, consider that you may be asking your pump to operate in a condition or application for which it was not originally designed.

Directional drilling is a broad term used to describe any boring that doesn’t go in a straight line vertically down. In fact, even in a vertical well, it might be necessary to deviate to avoid a geological formation or a previous stuck pipe, then return to the original path. In this instance, the driller uses sidetracking techniques.
In conventional drilling for oil and gas, the drill bit, drillstring, pipe and casing all go down in a straight line. If a driller aims away from the 180-degrees down, that’s technically directional drilling. Nowadays, however, it’s more likely that there’ll be a series of one or more carefully planned directional changes along the wellbore.
Directional drilling techniques have been employed for almost 100 years now. Over the past few decades, technological improvements have meant that angles, turns and underground distances covered are amazing feats of engineering.
Techniques such as multilateral, horizontal and extended reach drilling (ERD) are enhanced oil recovery (EOR) methods that can increase the yield of a downhole dramatically. It’s possible for ERD specialists to drill for more than 10 kilometers/6.2 miles. Students of petroleum engineering often get shown illustrations and diagrams that look like tree roots. If we imagine the rig as the trunk of the tree, the directional possibilities of the roots are endless. Even the branches of the roots are comparable to multilateral drilling.
Multiple down holes can be drilled from the same rig, minimising surface disturbance and environmental impact. Also, these boreholes can extend up to a mile down, and for more than five miles at shallower angles. In an oilfield with dispersed deposits, a large radius can be tapped, maximising the expensive asset which is the rig. Rigs and crews have day rates that run into the hundreds of thousands of dollars, one rig working up to five or ten square miles is very cost-effective in comparison to having a dozen or more vertical rigs, which may or may not be tapping into the same accessible reservoir deposits.
Geologists and engineers use terms such as an ‘oil reservoir’ or a ‘hydrocarbon reservoir’ to describe underground pockets of resources. Scientific terms give a label to help everyone understand each other, but Mother Nature has different ideas about the way she organises things.
People who perform well plans such as seismic geologists, geoscientists, exploration engineers and CAD experts join together to give the best idea of where oil and gas deposits may lie. Their estimates are based on different types of surveys, and past experience. What they’re unlikely to do is pinpoint the exact place where they’d access the maximum amount of resources.
When we see reservoirs of water, we can imagine dropping a giant straw into the middle and sucking up the entire lake. The flat surface area of the water and the likelihood of human-made dams and walls might give us a false idea of the topography of an underground reservoir. The bottom of the lake would provide a better insight into the random geometry of the dispersed resource. For example, if your imaginary straw happened to touch a shallow gravel bar in the middle of the lake, you might only extract a small percentage of the water.
On top of this randomness related to upper, lower and outer dimensions, there are plenty of other possibilities:By drilling at an angle, more of the reservoir gets explored, since they tend to form horizontally (between formations) not vertically.
The deposit might not resemble a reservoir at all, it might be oil-saturated sand or shale. Directional drilling is especially valuable in shale, where the formation can be explored to follow richer seams.
There’s some other reason why the reservoir is inaccessible from above, such as the surface land being a town, mountain, nature reserve or area of special scientific interest (SSI).
Rather than the oil and gas settling in a single deposit, it’s in separate distinct pockets, not clearly joined to each other. This can occur where there are multiple bed dips or altitudes.
It’s common to find deposits below salt domes or fault planes, where the driller faces increased technical risk. Horizontal drilling can avoid salt domes, and reduce pressure on equipment near fault lines.
In fact, these ‘irregular’ reservoirs are very common. Now that relatively fewer elephant reservoirs are being discovered, and technology improves, directional drilling becomes more critical each year.
Another use for directional drilling is in the event of an uncontrolled, or ‘wild well’. If you imagine a well that has broken through the blowout preventer and is gushing, how can you cap it?
This depends on the amount of underground pressure. In some instances, a second control well is drilled so that it intercepts the same point where the original wellbore meets the reservoir. Once the new directional well is completed, it can be pumped with kill fluid.
If the well pressure isn’t too severe a relief well can help to release gas so that the original gusher reduces in intensity, allowing it to be controlled. Mud and water are pumped in from a different angle, to get the first well under control and back to proper working order.
It’s not possible to see hundreds of metres underground, in fact, the drillers and engineers rely entirely on technology to ‘see’ where they are going. A directional driller has a guide that has been created by the engineers and geologists. Every 10-150 metres, (with 30-40 being typical), survey data is sent back to make sure that the original ‘blue line’ well path is being followed.
Directional drilling software receives input from multiple measurements while drilling (MWD) sensors in the drill bit, and at any branches or junctions. (Other measurement tools include Electromagnetic MWD and Global Positioning Sensors (GPS)). In addition to MWD technology, mud loggers use logging while drilling (LWD) sensors and software. The drill bit has vibration sensors that can detect the type of formation being drilled at any point. Collars can be added along the length of the well, sending back information to the surface regarding torque, weight and bending.
From the surface, electromagnetic sensors can also track the progress of the drill bit. When all of the data from the drill bit, collars, motors and the surface equipment enter the control panel, a complete representation occurs.
As well as being able to know what is going on, even a mile along the drill bore, drilling engineers can make adjustments in real-time that ensure that everything is going to plan. This is especially relevant when unexpected things occur concerning geology or severe equipment stress.
If you were to imagine the mechanics of directional drilling without seeing the technology, you might wonder how the drill could suddenly change direction. Since the motor that turns the drill is at the surface, how can the drill string continue to rotate at 360 degrees while going around a corner?
We now have downhole drilling motors, that can drive the drill bit in a completely different direction to the usual 180-degree downhole starting point. Turbodrills and rotary steering drills are employed in directional situations where they’re best suited.
The rotational speed of the drill and the weight and stiffness of the drillstring can also be used to influence direction. One of the original methods was jetting, a high-pressure nozzle shot water or drilling fluid from one edge to the drill bit, creating a weaker side in the formation.
Another traditional method was to use a whipstock. A whipstock is a type of wedge that can redirect the drill. At the desired depth the drill is withdrawn to the surface, a whipstock gets put in place, then the drill goes back down and gets redirected by the whipstock. Next, the drill is brought to the surface again, the whipstock pulled out and then drilling resumes and the bore changes path.
Drill bit sensors can tell the driller about external weight, and rotary speed that can also be used to influence the trajectory. Mud motors can also be used to change direction. With a steerable drill pipe, there’s a bend near the bit. The drillstring stops turning, and then there is plenty of time to use chosen directional techniques to reposition the bit to the desired trajectory. When it starts spinning again, it’ll start going in the direction that it’s now pointing towards. (More about steerable mud motors in the next section).
Specialised drillbits are used to improve performance and reduce the chance of failure. Schlumberger supply directional PDC drill bits for both push- and point-the-bit rotary steerable systems. Horizontal Technology, Inc. provides ‘Varel High Energy Series bits’ designed for the unique, rigorous conditions of horizontal directional drilling.
Mud Motors. Downhole steerable mud motors get positioned near the drill bit, which has a bend in it. What happens is that at the correct depth the drillstring stops rotating, then drilling fluid is pumped through the mud motor so that the drill bit starts to turn just due to the force of the liquid. This mud pressure pushes the drill bit into a different angle, and also begins to bite into the formation at a different angle to the central well trajectory. Once the sensors verify that the drill bit is pointing in the right direction, the drillstring starts to turn again.
Rotary Steerable Systems (RSS). Directional drilling by using the mud motor means that often the drill pipe needs to be slid forward while the drill is motionless. A rotary steerable system can drill and steer at the same time. This means that previously inaccessible formations can be accessed.
Custom whipstocks that work with downhole motors don’t need removing in between drilling. These are a significant advance on the old fashioned ones previously mentioned. More time can be spent drilling, and less time removing the drill bit and conventional whipstock.
Networked or wired pipe. The Intelliserve system from National Oilwell Varco is a broadband networked drilling string system. It can transmit data from the sensors back to the surface.
Well integrity is perhaps the most crucial aspect of directional drilling. Drilling at deeper, or extended distances, and especially changing direction causes a number of additional engineering challenges and stresses on the equipment.
For example, a downhole drilling motor will always be far smaller and less powerful than one connected to a robust drilling rig above ground. It’s more likely to fail, or have insufficient torque or speed to get through challenging geological formations.
The drillstring itself will be less stressed when going in a straight line, every degree of turn add extra friction and unbalanced pressure. If drillstring integrity isn’t maintained, the drillstring can snap or get jammed. It could mean that a brand new set of equipment is needed, and a new well might need to be drilled again in a slightly different direction.
Maintaining hydraulic pressure, and wellbore cleaning is much more challenging with these types of wells. Modern directional drilling equipment is so advanced, it can cope with high pressure/high-temperature HP/HT conditions, a mile away, after the wellbore has changed direction.
Computer simulation programmes are used to simulate the well plan. 2D and more recently 3D modelling programmes give the geoscientists and engineers a visualisation of the planned path. This software is created based on previous knowledge, current seismic and magnetic data, supplemented with real-time data from the MWD instruments.
There are a few different types of directional drilling. Multilateral drilling is where a downhole bore has multiple lateral (90 degrees) offshoots. For example, a well might be 1000 metres in depth but have numerous lateral wells connected to it. Extended reach drilling (ERD) is categorised by ever longer wellbores drilled from the rig.
Land tenders offer the right to explore and extract resources from a particular square meterage of land. It’s possible to purchase a lease for an oil patch, then drill horizontally into neighbouring territory. Close to a national border, it’s been known for drillers to drill into another country.
This is different from straightforward situations, where two territories happen to tap into the same reservoir. The industry has guidelines and regulations. Simultaneous operations (SIMOPS) and combined operations (COMOPS) have strict procedures for situations where well interference can occur.
Of course, the majority of horizontal drilling is done for good reason, not to cross borders of ownership or sovereignty. Sometimes horizontal directional drilling is the only possible way to tap a reservoir, such as the case of dilling under a town or nature reserve. Other times it’s a cost-saving exercise, to drill under a salt dome or mountain. Lastly, drilling horizontally can be the best way of maximising extraction by reaching more sections of a reservoir.

Mud pump manufacturers often provide two types of mud pumps. In fact, the power end and the hydraulic end of the pump are the same. The difference lies in the way the pump discharges the mud.
In the early 1990s, it was generally recognized that medium and small drilling rigs used text boxes:, high pressure (1800-2200ps i, ie 124-152bar) and low flow (5-25gpm, ie 19-95Lpm) pumps to send flushing fluid In the hole.
With the maturity of the drilling industry and the rich experience of operators, it has been found that higher mud flow and lower mud pressure are an excellent method for drilling. In some formations, high pressure and low flow are still the first choices, and have achieved the greatest success. However, in most areas, a higher flow rate can best ensure the cleanliness of the hole (removal of cuttings) and provide sufficient bentonite for formation plugging and lubrication.
When high pressure (800-1000psi, 55-69bar, and higher) and lower flow are required, plunger and sealing technology are used. The fluid pressure pushes the front part of the seal, pressing the seal around the smooth surface of the reciprocating plunger, preventing leakage. When the pressure is lower than 800-1000 psi (55-69 bar), the liquid flow pressure is not enough to promote this isolation, and the seal leaks. The leaked liquid carries sand and other abrasive solid particles into the well and collects between the seal ring and the plunger, causing rapid wear of the plunger surface and/or seal, and failure of good packing.
One advantage of the plunger and sealing technology is that the operator can adjust the leakage of the seal to a minimum until the pump can be used effectively and the borehole is completed.
Pumps with piston and liner technology work in the opposite way. In the case of low hydraulic pressure (less than 1200psi, that is, 83bar), the piston prevents leakage well. The diameter of the piston is usually larger than that of the plunger. It is an advantage to allow the pump to run slower when discharging the same flow rate.
The piston has two disadvantages. First, when the piston is damaged or starts to leak, the operator cannot maintain the status quo until repairs. Therefore, after an obvious leak, it usually must be repaired immediately. Second, the piston is suitable to run under cooling and lubrication. Therefore, a cooling and lubrication system must be used to increase the durability of the piston.
The cooling and lubrication system includes small centrifugal pumps, nozzles, pipes and collecting tanks. The system sprays a mixture of water and lubricant (non-foaming soap or liquid polymer) onto the back of the piston.
Many drilling rigs are equipped with plunger pumps. Plunger pumps are often used in applications where piston pumps should be used (mainly low pressure and high flow), and often have leakage problems. In order to help operators eliminate the leakage of these pumps, some pump manufacturers are developing conversion components that can change the pump from a plunger type to a piston type. Ask the manufacturer of your drilling rig or pump if it is available from stock.
From an economic point of view, when the plunger is no longer applicable and must be replaced, you should consider changing the pump from the plunger type to the piston type. The conversion component can be installed on site, and it is very easy to operate.
If your mud pump has a leakage problem, you should think about whether your pump is working under conditions or uses that do not meet the original design.
