NOV ASEP Elmar has now designed, manufactured and tested its first fully electronic remotely

operated well intervention equipment. NESSIE, which stands for NOV Electric Smart System

Intervention Equipment, is set to revolutionise the field of wireline intervention control by

enhancing the efficiency, accuracy and reliability of operations, resulting in optimised production

from wells and maximizing return on investment. NOV ASEP Elmars engineering director CarlWood and Keith Dempsie, principal engineer of NOV ASEP Elmar, explain the thinking behind

this exciting innovative system.

The technology behind wireline pressure control equipment (WPCE) has come along way since

NOV ASEP Elmar designed and introduced the very first wireline valves (formerly referred to as

wireline BOPs) in the 1950s under the Bowen name. The latest electric generation of WPCE,

which is designed in-house by NOV ASEP Elmars engineering team, will change the way that

offshore wireline operations are conducted worldwide by primarily improving the safety, flexibility

and control of well intervention activities. (see page 7)

intervention control can cut costs

NOV Hydra Rig has just completed manufacture of two recessed reel truck mounted CTUs thatare destined for Russia. The Terberg chassis utilizes a Volvo cabin, controls, transmission, and

a Volvo Euro 5, 440hp engine. The unit is winterized to -50C for operation in Arctic conditions

in Siberia. These particular chassis are 10 X 8, but 10 X 10 units are available. The split

frame design enables NOV Hydra Rigs Patented DID designed reels to fit thru the frame. The

split frame design significantly increases the capacity of a bodyload coiled tubing unit while

maintaining a road legal height, and at the same time lowers the CG of the unit for more stable

handling in off road conditions. This DID has a capacity of 14,500 of 1-3/4 tubing. A HR560

Injector is mounted on a hydraulic tilt stand for leaving the tubing stabbed during transport.

NOV Hydra Rig introduces MicroCoil capillary units

The NOV Hydra Rig MicroCoil Compact Well Intervention unit has a combined power pack and operator cabin, integrated into a single

fully-enclosed offshore-style container. The power pack and operator cabin drives and controls a number of alternate well-intervention

systems such as slickline, capillary tubing or small coiled tubing. The unit can be operated with or without the optional wire-line module

attached. The functionality of the wireline module and capillary components are independent of each other.

The containers power pack compartment (sound reduced to 83 DbA average) contains the major diesel/hydraulic assembly. If required

the unit can be ATEX/ Zone 2 certified for offshore use.

The operator cabin compartment is fitted out with the control panel and operator chair. The control console is a designed for ease

of use and maintenance. It features direct hydraulic controls and instrumentation is provided for weight and depth. A NOV data

acquisition system or customer supplied system is integral to the control console. The cabin compartment is double-insulated and is

provided with heating and ventilation.

Together, the combined power pack and operator cabin container and secondary open-frame container form a complete capillary tubing

spread. Capillary coiled tubing may be used for placement of well treatment chemicals and can be appropriate for nitrogen injection for

well kick-off.

There is a standard option to install a slickline winch module. This is supplied as a separable container, bolted to the front of the

combined power pack and operator cabin when in use. When separated for transport or storage, the slickline winch module is fully

enclosed, damage resistant and weatherproof.

The combined power pack and operator cabin is designed to fully utilise the NOV Hydra Rig HR420 capillary injector.

The compactly designed HR420 capillary injector has a rated pull of 20,000lbs, a rated snub of 10,000lbs and weights just 1500lbs

(700kg). Two fixed displacement motors drive heavy duty chains with precision cast gripper blocks to suit capillary tubing, cable and or

coiled tubing from OD to 1 OD.

New 6.375 Triple BOP and 4.06 Two Door Stripper Packer

The Improvements in the BOP will decrease the time required to conduct regular maintenance on the equipment with the addition of

the hydraulic ram change system. This system has been used before on smaller BOPs and it has been improved for the 6 3/8 ES

to make it easier to assemble. The shearing capacity has increased with a larger piston on the shear seal actuator. The BOP has

passed all of the API 16A qualification requirements, and additional requirements from API 6A, NORSOK, and ISO. Our qualification

testing includes a gas test.

The Two Door Stripper Packer improvements is the addition of

an external visual indicator. The indicator is attached directly

to the main piston, as the stroke of the piston increases the

indicator will show percentage of packer wear. As you approach

the stroke of the piston the packer assembly will be worn to

levels that is must be replaced. The system also allows for

an electronic LVDT to be attached so that the wear can be

monitored inside the control cabin.

Field operations with high angle or wellbores with long

horizontal sections can present a unique set of challenges.

Successful outcomes are dependent on the use of advanced

technology.

In these scenarios, gravity can no longer be used to deploy theBottom Hole Assembly (BHA), and the coiled tubing (CT) must

be used to push the BHA to the desired working depth.

Friction forces (acting between the CT surface and the

surrounding tubulars) increase as push is sustained, resulting

in helical buckling of the tubing. If pushed far enough, the CT

will eventually experience lockup, preventing any additional

forward movement of the BHA and potentially limiting the

success of the field operation.

Fortunately, there are several methods of reducing friction

forces in long horizontal wellbore sections. One of these ourfocus here is the application of gentle downhole pulsation, or

vibration energy, on the CT string (by way of devices such as

the NOV Downhole Agitator), to gently oscillate the BHA to

reduce friction for the purpose of delaying the onset of lockup,

thereby allowing further penetration into an extended-reach

well.

This friction-reduction technique also helps to mitigate the

slip/stick movement of the CT that occurs in some situations,

allowing for more constant weight on bit (WOB) when

performing milling or drilling operations.

Key challenges encountered when using a downhole pulsation

device are: 1) accurately predicting the additional depth of

penetration that is achievable with the use of the tool, and 2)

accurately predicting the additional amount of available WOB

that is deliverable as a result of reduced friction. Its important

that these predictions are made correctly prior to mobilization

of the equipment to ensure that no opportunities are missed; or

conversely, that the field operation is successfully performed.

NOV CTESs Cerberus softwares modeling capabilities can be

used to answer both of these challenges. Within the software,the friction-reducing properties of various downhole tools are

definable by user inputs. These user inputs are then used to

provide an analysis of the friction reduction achievable by use

of the pulsation tool. More importantly, the pre-job analysis

provides an estimate of the additional CT penetration depth

that can be achieved as a result of the friction reduction

provided by use of the pulsation tool.

According to a 2009 SPE paper presented by Ken Newman et

al.1, Case histories show that the [Cerberus forces] model gives

reasonable results when compared to measured field data.

The figures below represent the Cerberus modeling results

obtained in a case study described in the referenced SPE paper.

Bottom line: Downhole pulsation tools can help delay the onset

of CT lockup and can extend the reach of the BHA in wellbores

containing long horizontal sections, and Cerberus software canprovide effective modeling of these types of operations.

NESSIE Technology

The NESSIE system is designed to ensure that even the most delicate adjustments to pressure control or grease injection can be done

instantly from the safety and comfort of the winch cabin, without a diesel engine. The essence of the technology is incorporation of an

NOV ASEP Elmar SmartMonitor realtime computer-generated interface in the winch control cabin which instructs the units on a fully

automated basis. Out-with the winch unit, NOV ASEP Elmar CAN-bus technology eliminates hydraulic control up to the point of the

wireline valve (WLV) control skid.

By replacing hydraulic connections with CAN-bus technology and integrating SmartMonitor technology within each unit, the end result

is a complete electronic well control and winch package consisting of an e-drive winch system, a WLV control skid, a grease injection

skid and a wellhead pump master valve unit.

The SmartMonitor hardware is a touch screen computer that controls all aspects of the wireline operation including; wire lubrication and

tension, the display of real time imagery from cameras as well as controlling safety protocols. The result is a quieter, more controlled,

environmentally friendly product that can be operated remotely from anywhere in the world.

Technical challenges

One of the biggest challenges encountered during the design process was developing a method to synchronize the automatic controls

of the SmartMonitor with the manual controls of the WLV control skid. The intelligent process advanced, named physical feedback

by the companys engineering team, ensures that in the event of an emergency where manual control is required to override theSmartMonitor control, the handles are in the correct position for an engineer to operate instantly.

NOV ASEP Elmar carried out an intense program of testing to ensure high performance and reliability of the new electronic solutions

and techniques. Cold weather testing was conducted in a test chamber to temperatures as low as -20C in order to verify the systems

reliability, even in the harshest conditions.

Cost-effectiveness

With rig costs running into millions of dollars a day, developing cost sensitive technologies without compromising safety or performance

is paramount.

When it comes to service life and maintenance checks, NESSIE technology is longer lasting and more effi

cient. The SmartMonitorsinitiate regular health checks scheduled according to actual usage time rather than calendar based scheduling, which is less efficient.

Maintenance costs are therefore much lower than hydraulic power equipment resulting in a cost-effective method for intervention

activities.

Conclusion

NESSIE is indeed a major step forward in using software and electronics to drive innovative, reliable and cost-effective intervention

equipment during oil and gas exploration worldwide.

Quiet, environmentally friendly, safe, reliable, cost-effective and high performing electronically driven equipment is the new direction of

well intervention pressure control technology and NESSIE is set to revolutionise the field of well intervention control.
