Production Optimisation - Well Monitoring Performance and Communications

Client: Global OperatorLocation: Middle EastEquipment: Proserv Smart Box

Project Background

Our client had 800 onshore solar powered wells with basic hydraulic controls with no communication back to their control centre.

Due to the amount of panels and their location and geographical spread, they were only able to visit each well every four to eight weeks. Varying well pressures were tripping the panel and closing the well safety valves, losing up to 1000 BOE/D, without any notification in some instances.

Solution

Proserv developed the Smart Box, which was

manufactured by our engineering teams in the Middle East as a real-time monitoring solution for evaluating onshore and offshore wells in remote sites. Unplanned shutdowns can cost operators up to one percent of total annual production. With the Smart Box, shutdowns are detected instantly, avoiding prolonged production losses and lowering operating costs.

The Smart Box is an intelligent device with an inbuilt GSM modem that collects information from production equipment at the well site then transmits alerts to personnel via GSM straight to a mobile

device. This ingeniously simple technology solution can be embedded within any of our systems and customised to a client’s exact specification for increased operational efficiency.

Conclusion

This is a perfect example of how Proserv can use its extensive engineering capabilities to quickly develop an ingeniously simple technical solution to solve a very particular client challenge and provide significant cost savings.

Benefits

• Smart Box solution saved the client

Project Background

Maersk has embarked on a programmed of work to decommission the Leadon Field in the North Sea. Proserv was engaged to supply a solution for the internal cutting and recovery of wells in the South Cluster during March 2016.

The semi-submersible Serco 704 was contracted by Maersk to complete the work and Proserv deployed its Multi-String Cutting (MSC) equipment spread to complete the operation.

Solution

Proserv’s Multi-String Cutting tool

uses abrasive water jetting technology and was selected as the solution to conduct internal well severance. This method was chosen over traditional methods as it offered significant time savings and the adaptability to sever strings made up of differing IDs, cemented or un-cemented.

Tooling to recover the severed wellheads was also mobilised allowing single trip severance and recovery. The cutting time for a three string well ranged between four and six hours with the eight well campaign completed over the course of nine

operational days.

Conclusion

This is the first rig-based well severance and recovery project completed by Proserv in the North Sea.

The operation was completed ahead of schedule with well severance times exceeding client expectations. A strong collaborative effort between Proserv, the client and rig teams resulted in an efficient and successful campaign.

Benefits

• Reliable cut of cemented or non-

cemented casing strings

• Contactless cutting technology reduces risk of stuck in hole

• Single trip severance and recovery

• Adaptable tooling that can deal with various casing IDs

• Reduced vibration in drill string

Decommissioning Rig-based well severance and recovery

Client: MaerskLocation: Leadon, North Sea, UKCSEquipment: Multi-String Cutting (MSC) tool

Project Background

With a step out distance of 6 km and water depth of 1200m, the challenge was to provide communication from an existing topside system to the subsea system via power-line communication, co-existing with FMC KOS 150 SCM’s. The key requirement was to optimise system performance, delivering a design life of 20 years.

Solution

Proserv delivered a retrofit Open Communications Hub (OCH) solution to provide co-exist hi-speed communications

on the power line with existing SCM. This enabled the conversion of AC high-voltage to DC with the provision of power management subsea to all instruments.

Scope

The provision of high bandwidth communications and co-exist technology with the existing subsea system delivered all the key requirements on performance as set out by the client.

Conclusion

The system was qualified to provide shared electrical power with the P6 Production

SCM and utilise a fibre optic distributed temperature sensing and P/T gauges (FBGs) to monitor functionality of the P6 gas lift system.

A marinised DTS (in-well Distributed Temperature Sensing) solution was developed and the installation of fibre optic technology provided a platform for Shell to evaluate fibre optic technology for future applications.

System Optimisation OCH retrofit

of the BOP stack hydraulic control lines

• Meantime to failure improvement

• Improved BOP stack reliability

Project Background

A leading Drilling Operator requested the preventative assessment of a BOP stack as a measure to review maintenance processes that may have led to $20 million in downtime.

Solution

Proserv introduced a BOP Integrity Program aimed at assessing complex mission critical control system fluid flow components, supports, and connections.

Based on the findings of the assessment, training plans were proposed to help improve maintenance

processes.

Scope of Work

The Proserv team mobilised on location to perform the assessment beginning with tubing and pipe mapping routes for length, line identification and supports.

Once tubing and pipe identification was recorded an evaluation of tube fitting make-up and life fatigue using Proserv’s proprietary gauging system could be properly noted for future maintenance tracking throughout the system.

Life fatigue contributors such

as vibration and human error due to improper clamp restraint placement were outlined. Visual and liquid penetrant testing of welds was performed to insure system fitness for service along with an evaluation and inspection of the control valves for optimum performance.

In closing, a process performance improvement audit plan was prepared and presented to the customer for review and determination of an action plan going forward.

Benefits

• Overall health check

Operational EnhancementBOP Stack Integrity Assessment

Client: A leading drilling operatorLocation: USAEquipment: BOP control system refurbishment

Project Background

KCA contracted Proserv to carry out the refurbishment of an entire BOP control system which was manufactured in 1984 and had been in use since 1986.

Solution

Proserv’s skilled engineers refurbished the entire BOP control system changing out ‘like for like’ and refurbishing pumps and machinery where necessary. New tubing was also installed and all the electrical controls were changed out with new.

Conclusion

As the system was built in 1984, it had other requirements than systems of today. Refurbishment of the current system and changing some of the components ‘like for like’, was significantly less expensive in comparison to buying a new one whilst still being within API 16D regulations.

Our skilled teams delivered the system within a very short timeframe and managed the deadline even when having it pushed back four weeks.

Changing out tubing and installing it in

a new way ensures the maintenance of the stack manifold will be much simpler. Furthermore, it will reduce time spent on maintenance both on the stack manifolds and the rest of the BOP control system in the long-term.

Operational EnhancementBOP Control Refurbishment

Client: Multi-national oil & gas companyLocation: NorwayEquipment: BOP control system refurbishment

Project Background

The client required a solution for attaching retrofit cathodic protection to 88 windfarm monopiles using remote intervention. Four connection points per monopile were required to allow the installation of anode matresses which were to be positioned on the seabed around each pile.

Solution

Proserv provided their HMS 3000 friction welding technology and worked together with a third party tooling supplier to provide a solution that enabled the welding

of M16 carbon steel studs directly to the monopiles. These studs then allowed for cables from the anode mattresses placed on the seabed to be directly connected to the monopile therefore providing the required cathodic protection. The Proserv technology allows for the welding tool control panel to be integrated with the ROV and the hydraulic feed taken directly from the ROV’s HPU.

Scope

Proserv carried out an initial weld qualification process which was approved by DNV, laying the foundations for the

offshore scope to be undertaken at a later date. During offshore operations Proserv provided a complete HMS 3000 friction welding system consisting of a subsea weld head, subsea control system which was integrated into the project ROV, subsea stud changer and qualified personnel.

Full contingency of equipment was provided and all welds were completed to the client’s full satisfaction. Real-time data was recorded and issued to the client to show the operation was carried out as per the approved procedure by DNV.

Conclusion

The provision of the HMS 3000 system and stud changer allowed for the project to be completed without the need for diver intervention. The DNV qualified weld procedure gave the client confidence that welding operations would provide the requisite cathodic protection without compromising the structural integrity of the monopiles during

the welding operation. The provision of the cathodic protection has extended the working life of each monopile.

Benefits

• No need for diver intervention

• Cost savings through preventative maintenance

• High quality, high integrity approved cathodic protection solution

Wind Farm Cathodic Protection Anode Attachment (Friction Welding)

Client: StatoilLocation: North Sea, UK SectorEquipment: Friction welding

Project Background

A subsea christmas tree sustained significant damage from a mooring chain of a nearby vessel, including the shearing of structural members and detachment of the gas lift jumper. This damage halted production from the well until such time as the gas lift line was reinstated.

Solution

A spool support frame was developed so that the orientation and attitude of the replacement spool could be adjusted to adopt that of the damaged tree. An ROV operated, semi-

automated flange bolting tool completed the connection.

Scope

The scope of supply included removing damaged sections of the gas lift spool, delivering and supporting a new spool on the seabed adjacent to the tree, and connecting the new spool flange with the existing via a standard API flange. Pressure testing of the completion was required to verify integrity of the connection.

Benefits

Provides a qualified, industry standard,

bolted flange connection in a subsea environment.All tooling used for the bolting operation is removed from the spool, guaranteeing enduring integrity of the spool.Support frame isolates flange from external loads, and allows the location of the spool to be adjusted in 3D space.

Benefits

• Conceptual design took less than one week

• Design and build took four weeks

• FAT took less than two days

• Integration testing took less than two days

• Offshore deployment took less than four days

• Production was restarted immediately

• Production has continued since the spool was installed

• System working pressure is 5000psi

Project Background

Due to paraffin wax build-up on a subsea well and flow line, production was being lost from the Crathes field.

Large volume representative samples were required from the Christmas tree to allow specialist wax analysis to be carried out onshore.

Solution

Upon award, a project team was quickly established. Proserv designed, built, assembled, tested and shipped a subsea sampling system within 11 days of official call off.

Results

12 litres of samples were taken within a 24 hour period. Subsequent laboratory analysis confirmed that the samples taken were of high quality, both consistent and truly representative of the produced fluids.The samples supplied the information required to make critical production related decisions.

Scope

• 6 x 2 litre sample cylinders

• 2 x 2 litre waste cylinders

• Water depth of 100 meters

• System pressure rating of 1,000 psi

• Isothermal sampling - circulation of hot water to reduce risk of wax and hydrate formation

• Compact design to interface with Christmas tree

Benefits

• Sampling direct from Christmas tree

• Single or Multi Phase configuration

• Easy to use diver interface

• Subsea cylinder heating

• Closed loop design for zero discharge
