11 Well Contract with Major North Sea Operator
Metrol are pleased to announce the award of an 11 well contract from a major North Sea operator to provide long-term wireless downhole barrier integrity monitoring as part of their abandonment program. The 11 subsea wells will be monitored wirelessly for up to 5 years.
As the world-leader of downhole acoustic and electromagnetic wireless telemetry, Metrol have been supplying systems for the remote monitoring of shallow and deep-set plugs in platform and subsea wells for many years.
The interchangeable nature of Metrol’s technology allows great flexibility during subsea operations. Using TRITON*, pressure monitoring is provided without well intervention as an offline operation limiting environmental exposure. Intervention time is reduced and operational life is extended, providing greater downhole understanding, and reducing overall costs.
* Subsea Wireless Pathway
Wireless telemetry reducing cost and risk for integrity monitoring.
In 2017 Metrol completed four successful downhole wireless interrogations proving barrier pressure integrity. The right monitoring of pressure integrity of shallow set barriers is an essential part of a major UK North Sea operators abandonment program of eleven wells.
Using Metrol’s TRITON sea-bed communication system our company can continue to provide long-term wireless downhole barrier integrity monitoring without well intervention. This allows us to effectively monitor the well for up to five years, while limiting environmental exposure, reducing operational and commercial risk as well as cost and providing downhole visibility and barrier confidence.
What is wireless telemetry?
Wireless telemetry typically involves inserting a signal from surface to the wellhead. There are no drilling feedthroughs or penetrations as the tools are simply attached, and transmit right through to wireless transceivers installed lower down in the well.
Success with Metrol’s theft and damage proof technology.
Access to Oil wells located in the Niger Delta in Nigeria can be difficult and dangerous.
In 2014 Metrol installed a wireless bottomhole data acquisition system in a remote well in the Delta region. Pressure and temperature data has been delivered wirelessly to the client’s office for the last three and a half years, avoiding the mandatory annual visits to the well site to collect data.
Unlike conventional surface powered systems like solar panels that have previously been vulnerable to theft and damage, Metrol’s integrated surface system is disguised as a wing valve. It has no wellhead penetrations, contains both a wireless transceiver for downhole communications and a satellite for onward transmission, ensuring safe, seamless and reliable reservoir monitoring.
Since operating business 30 years ago, Metrol has equipped over 1,000 wells with its wireless technology.
Ensuring the future potential of new oil discoveries in Senegal
Senegal, a country on Africa’s west coast is on the verge of an oil and gas boom, as newly discovered oil and gas fields are expected to begin production within the next decade.
Using the PARAGON-EM wireless system Metrol is helping our project partner to gain better insight into the size and scope of a new development off the coast of Senegal.
The PARAGON-EM wireless system allows pressure gauges to be left in a well, below a cement plug, and be monitored wirelessly for months or even years.
When adjoining wells are drilled and flow tested, these gauges will detect pressure pulses based on reservoir connectivity and continuity. This system helps define the size of the field, plan efficient drainage and help decide location of future wells.
