workover rig companies in colorado made in china

The land drilling market worldwide is structured primarily as a rental market, not a sales market, where land drilling companies lease their rigs to E&P companies for an agreed period of time – weeks, months, or years – at a day-rate. The rigs are then used to drill wells and execute the E&P’s drilling programs.

Drilling opportunities are analysed and explored in order, leaving a series of dry holes, until a discovery is made. It is rare for an E&P company to actually own the rigs which they operate, but there are some exceptions such as Chesapeake, who will purchase their own fleet of rigs.

Under these rental contracts, a turnkey cost is paid by an E&P business to a middleman. This includes an insurance premium, which is returned if nothing goes wrong, but may be lost if there are difficulties. Higher specification equipment commands a larger premium.

Investors require a minimum level of return for their investment dollars in drilling operations, and typically equate cost with risk. These turnkey drilling contracts may limit risk by guaranteeing a minimum number of wells that can be drilled with the rig. The contract will also outline how the rig can be used – including the pieces of equipment, when to change pieces, temperature and pressure tolerances and the weight of mud.

The International Association of Drilling Contractors (IADC) lists 547 members in the category of Land Drilling Contractors. According to Statista, the key US land drilling contractors are: Nabors Industries Ltd, Helmerich & Payne Inc, Patterson-UTI Energy Inc, Precision Drilling Corporation and Pioneer Energy Services Corp.

Nabors operates the world’s largest land drilling rig fleet, with around 500 rigs operating in over 25 countries – in almost every significant O&G basin on the planet. It also has the largest number of high-specification rigs (including new AC rigs and refurbished SCR rigs) and custom rigs, built to withstand challenging conditions such as extreme cold, desert and many complex shale plays.

Headquartered in Tulsa, Oklahoma, H&P is a global business with land operations across the US, as well as offshore operations in the Gulf of Mexico. It is engaged primarily in the drilling of O&G wells for E&P companies, and recognised for its innovative FlexRig technology.

Patterson-UTI operates land based drilling rigs, primarily in O&G producing regions of the continental US, and western Canada. The company also provides pressure pumping services to US E&P companies and specialist technology, notably pipe handling components, to drilling contractors globally.

Precision is an oilfield services company and Canada’s largest drilling rig contractor, with over 240 rigs in operation worldwide. The Company has two segments. The Contract Drilling Services segment operates its rigs in Canada, the United States and internationally. The Completion and Production Services segment provides completion and workover services and ancillary services to O&G E&P companies in Canada and the US.

Pioneer operates a modern fleet of more than 24 top performing drilling rigs throughout onshore O&G producing regions of the US and Colombia. The company also offers production services include well servicing, wireline, and coiled tubing services – supported by 100 well-servicing rigs, and more than 100 cased-hole, open-hole and offshore wireline units.

Together these five companies dominate the US rental market. Other smaller but prominent contractors include: Parker Drilling, Unit Corp, Independence Contract Drilling, Seventy Seven Energy, Schramm and Ensign Drilling. Beyond these players, the market is highly fractured, with many “mom & pop” style drillers.

In Texas, generally considered to be the centre of US land drilling, RigData reports that there are currently 678 active rigs – split between Helmerich & Payne (160), Patterson-UTI (85), Nabors (64), Precision Drilling (39) and 77 other drillers (330).

Most new onshore rigs, both drilling and work over rigs, are built by OEMs in China. In the US, the larger vertically integrated land drillers have in-house manufacturing operations, so they will outsource some equipment construction, but assemble the new rigs at their own facilities. The leading provider of US newbuild rigs is National Oilwell Varco.

The secondary market, where existing rigs are sold, is largely auction dominated with mostly older rigs changing hands. As a rule, the big land drillers do not sell their newbuild rigs, as each has their own flagship designs.

Full API coverage: The different components of our well-servicing rigs are manufactured to the following API standards:Steel structures, such as the mast: API Spec 4F

Highly maneuverable : Sovonex™ mobile drilling rigs and self-propelled workover rigs possess excellent driving properties in the desert, mountain, and other impassable terrains.

Powerful CAT engines and a custom-made chassis that can be equipped with single wheel full suspension enable well service operations in even the most remote areas.

Suited for corrosive environments: All steel parts are specially protected against corrosion through the application of multiple layers of ship paint. The same coating process is used in marine shipbuilding.

Reduced NPT: The mast is erected hydraulically to reduce time for rig up and increase safety. Likewise, all rig components have been designed to allow for fast assembly and disassembly.

With every service rig, we send technical staff to our customer to provide first-hand technical support. The engineer responsible for the rig design is always part of the service crew.

Chinese yard Cosco Shipping Heavy Industry has delivered a jack-up rig to compatriot company SinoOcean Offshore Assets Management for operation off the Asian nation.

The delivery is based on a memorandum of understanding reached between SinoOcean and Shandong Marine Group in October last year to charter and manage offshore drilling rigs the latter has ordered at Chinese yards.

The delivered rig SinoOcean Prosperous, formerly known as Energy Engager, is a Super 116E jack-up and was ordered by Shandong Marine’s rig owner Northern Offshore at Cosco’s Dalian yard in 2013.

The ABS-classed rig is 74.09 metres long, 62.8 metres wide and is capable of working in water depths of 106.68 metres and drilling to well depths of 9144 metres. It is equipped to accommodate 120 people.

In May last year, Northern Offshore’s jack-up rig Energy Edge sailed from Chinese yard Shanghai Waigaoqiao Shipbuilding for operations off Qatar, where it will participate in Qatar Petroleum"s huge North Field Expansion project.

Sanjack has been committed to the research of automatic workover technology for many years and has a perfect automatic workover technology development, production, and manufacturing system.

In recent years, a whole set of automation technology has been formed in the automation and intelligent development of automatic workover equipment. Through the application of module design, servo drive, integrated control, electro-hydraulic compound drive and other technologies, the supporting products suitable for various types of workover equipment have been developed to meet the needs of oilfield workover equipment upgrading.

Second floor platform automatic pipe arranging manipulator replace the derrick worker on the second-story platform, it is to use fully automatic grabbing/arrange pipe string erection operations, realizing unattended operation on the second-story platform.

Drill floor automatic pipe arranging manipulator can replace workers to complete the placement of the column on the drill floor surface, and connect single joint, thread connection, etc., to achieve unmanned operation of the drill floor for major workover operations.

Two kinds of automatic make-up and break-down equipment with different structural forms and different characteristics replace the manual push-pull operation of hydraulic tong.

The tong body floats and hangs, and the tong mouth automatically aligns the center of the pipe string, which can be clamped reliably without damaging the surface of the pipe body.

The original integrated structure of hydraulic tong and punching tong can meet the thread up and down of tubing/drill pipe at the same time. The tong head has a floating function, which can automatically compensate the center deviation between the pipe string and the jaw and reduce the damage when the tong teeth clamp the pipe body. The torque can be accurately controlled and set, and the make-up torque of pipe string meets the requirements of API. When in standby, it can rotate and give way as a whole to provide more active operation space for the drill floor. The tong head can be deflected to meet the make-up & break-down of the mouse hole string.

Instead of the traditional mechanical elevator, the hydraulic drive valve is opened and closed, and the elevator is deflected and overturned, so there is no need to lift the elevator manually.

Main function: replace the field worker to lift the pipe string and realize the automatic transportation of the pipe string from the ground to the drill floor.

The installation centering and positioning mechanism is designed to realize the accurate positioning of the equipment at one time and shorten the installation time.

The push pulley is designed to realize the traveling sliding between the pulley and the pipe string and effectively protect the screw thread of the pipe string.

It adopts programmable integrated control and industrial network communication to realize centralized control, process management and status monitoring of all automation equipment.

The hydraulic station provides hydraulic power for automatic loading and unloading hydraulic clamps, hydraulic elevators, pipe string conveyors, drill floor manipulators and other equipment.
