National Oilwell Varco (NOV) is an American multinational corporation based in Houston, Texas. It is a leading worldwide provider of equipment and components used in oil and gas drilling and production operations, oilfield services, and supply chain integration services to the upstream oil and gas industry. The company conducts operations in more than 600 locations across six continents, operating through three reporting segments: Rig Technologies, Wellbore Technologies, and Completion & Production Solutions. National Oilwell’s two main predecessors, Oilwell Supply and National Supply, were founded in 1862 and 1893, respectively. These two companies manufactured and distributed pumps and derricks.

The Hex Pump is an axial piston mud pump with six vertical pistons driven by two AC motors via a gear and a specially profiled cam. In contrast to crankshaft-driven triplex pumps, the Hex pump delivers a nearly pulsation free flow. Consequently, there is no need for pulsation dampeners on either the suction or discharge side when running this pump. Other major advantages are compactness (reduced weight and footprint) and no need for replacing liner sizes to achieve high pressure or flow. The Hex 240 version with 4 1/2" liners has a rated capacity of 2540 HP, a maximum rated pressure of 7500 PSI and a maximum flow capacity of 1034 GPM.

The Hex Pump has substantially less weight than a comparable Triplex pump, and this results in increased variable deck load capacity on drilling units. The potential cost savings related to increased variable deck load capacity both on new builds and on existing rigs will be discussed in this paper. Also, the potential steel weight reduction in the substructure on drilling units will be discussed.

The Hex Pump creates a clean standpipe pressure with much lower pressure fluctuation levels than triplex pumps. Due to this, there are no need for pulsation dampeners when running the Hex Pump. This additionally leads to much better and cleaner MWD-signals for the directional driller. As a consequence, this will contribute to faster and more accurate drilling in long and complicated directional wells.

The design and development of the Hex Pump is described in SPE paper 79831, ref /1/; "Development and Performance Testing of the Hex Mud Pump", but for the understanding of this paper it is important to understand the functionality of the Hex Pump design. Some of the main items are therefore repeated in this paper. SPE paper 92507, ref. /2/, "Operational experience with use of a Hex Pump on a land rig" focuses on the improved MWD-measurements related to use of Hex Pump compared to triplex pumps. Some of the main items discussed there will also be repeated in this paper.

An integral part of onshore and offshore drilling, mud pumps circulate the drilling fluids used to facilitate drilling oil and natural gas wells. Used to stabilize pressure and support the well during the drilling process, drilling fluids also provide friction reduction and a means to remove cuttings.

While drilling with some type of fluid has been in practice for centuries, the term "drilling mud" was coined when a herd of cattle was driven through a wet field near Spindletop, and the resulting mud was used to lubricate the drillstring and drill bit. Drilling fluids have come a long way since those early days of drilling, and offshore mud pumps are constantly taxed to help operators find and develop hydrocarbons in harsher, deeper and more difficult locations.

"A mud pump delivers drilling fluid from the mud tanks, through the top drive, down the drill string and through the bit," explained Juan Lerma, Mud Pumps Product Line Manager at National Oilwell Varco. "When the mud exits the bit, it travels back to the surface carrying the cuttings made by the bit where it flows over a shale-shaker removing the cuttings, cleaning the mud and returning it to the tanks, where it"s used over and over again."

"A mud pump is one of the critical and required pieces of equipment for a drilling rig whether on land or offshore," Lerma stated. "Offshore, where real estate is at a premium, mud pumps are configured with a compact top-mounted drive system, reducing the overall length with a smaller package and strategically placing it in the pump room for permanent installation."

"Jackups semis and drillships all use the same mud pumps; however, the number of pumps installed in the pump rooms changes from rig to rig depending on the drilling specifications," explained Lerma.

Additionally, the rock formations and pressure encountered when drilling may vary; HT/HP and environmental conditions also may affect the drilling process, as well as the drilling fluids chosen and mud pumps required.

"As the drilling programs require higher flows and higher pressures, it is necessary to increase pressure ratings and either increase the number of mud pumps required or utilize larger capacity mud pumps," Lerma continued. "Most early jackups utilized two mud pumps and piping systems rated for 5000 psi work pressures and 1600 horsepower, while most of today"s jackups have 7500 psi working pressure and up to four 2200 HP pumps piping systems."

According to information gathered by premium rig data service RigLogix, National Oilwell Varco leads the pack in providing mud pumps to offshore oil rigs. Of the top six brands of mud pumps, NOV supplies four of them, garnering more than 70% of the offshore mud pump market.

Those leading NOV brands include National Oilwell, Continental Emsco (which was acquired by NOV in 1999), National and NOV. The other leading mud pump system is provided by Gardner Denver and is the third most popular type of system offshore. Additionally, Lewco, a division of Rowan, has about 4% of the offshore mud pump market, putting it fifth on the list of leading suppliers.

With more than four decades of experience providing the offshore industry with mud pumps, Lerma revealed that the company has been able to sustain such a high market share by constantly transforming the product to meet the needs of the industry. As offshore drilling programs have required higher flows and pressures, the company has strived to provide the best quality equipment, while maintaining the lowest cost of ownership.

To better serve its offshore clients, the company developed the Hex Pump in the last several years, and this new line of mud pumps has proven a success in offshore waters worldwide. Boasting 2400 HP, the Hex pump is capable of delivering up to 1,034 gallons of drilling fluids per minute, making it one of the most powerful mud pumps on the market today.

In 2004, the first two Hex Pumps were deployed on a Global Santa Fe rig working offshore West Africa, and in 2005, both the Noble Max Smith and the Noble All While started using the Hex Pump as well. In fact, the Noble Al White, working in the harsh conditions of the North Sea, was the first rig to be solely dependent on the Hex Pumps with two of them located in its pump room, and the rig now has more than 8,000 hours of successful drilling operations using the system.

"The first drillship to use the system, Transocean"s Discoverer Clear Leader just started drilling in the Gulf of Mexico with five Hex Pump systems," said Lerma. "Additionally, the soon-to-start-drilling Discoverer Americas houses four Hex Pumps, and the soon-to-be-delivered Discoverer Inspiration will have five."

A mud pump (sometimes referred to as a mud drilling pump or drilling mud pump), is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi or 52,000 kPa) down the drill string and back up the annulus. A mud pump is an important part of the equipment used for oil well drilling.

Mud pumps can be divided into single-acting pump and double-acting pump according to the completion times of the suction and drainage acting in one cycle of the piston"s reciprocating motion.

Mud pumps come in a variety of sizes and configurations but for the typical petroleum drilling rig, the triplex (three piston/plunger) mud pump is used. Duplex mud pumps (two piston/plungers) have generally been replaced by the triplex pump, but are still common in developing countries. Two later developments are the hex pump with six vertical pistons/plungers, and various quintuplexes with five horizontal piston/plungers. The advantages that these new pumps have over convention triplex pumps is a lower mud noise which assists with better measurement while drilling (MWD) and logging while drilling (LWD) decoding.

The fluid end produces the pumping process with valves, pistons, and liners. Because these components are high-wear items, modern pumps are designed to allow quick replacement of these parts.

To reduce severe vibration caused by the pumping process, these pumps incorporate both a suction and discharge pulsation dampener. These are connected to the inlet and outlet of the fluid end.

The pressure of the pump depends on the depth of the drilling hole, the resistance of flushing fluid (drilling fluid) through the channel, as well as the nature of the conveying drilling fluid. The deeper the drilling hole and the greater the pipeline resistance, the higher the pressure needed.

With the changes of drilling hole diameter and depth, the displacement of the pump can be adjusted accordingly. In the mud pump mechanism, the gearbox or hydraulic motor is equipped to adjust its speed and displacement. In order to accurately measure the changes in pressure and displacement, a flow meter and pressure gauge are installed in the mud pump.

The construction department should have a special maintenance worker that is responsible for the maintenance and repair of the machine. Mud pumps and other mechanical equipment should be inspected and maintained on a scheduled and timely basis to find and address problems ahead of time, in order to avoid unscheduled shutdown. The worker should attend to the size of the sediment particles; if large particles are found, the mud pump parts should be checked frequently for wear, to see if they need to be repaired or replaced. The wearing parts for mud pumps include pump casing, bearings, impeller, piston, liner, etc. Advanced anti-wear measures should be adopted to increase the service life of the wearing parts, which can reduce the investment cost of the project, and improve production efficiency. At the same time, wearing parts and other mud pump parts should be repaired rather than replaced when possible.
