Drill STEM Testing Services

JOENY offers the complete well test package, utilizing some of the industry’s most reliable technologies.

A major part of this is our Drill Stem Testing (DST) offering, where we provide multi-function and single-cycle cased hold DST tools for exploration well testing.

Drill Stem Test offers the fastest and safest method of evaluating the potential of a newly discovered hydrocarbon-bearing formation. After the well has been drilled and cased, the first stage of a well test is to run a DST string in conjunction with Downhole data system and Tubing Conveyed Perforation (TCP) and Sampling.

The DST bottom hole assembly is designed around your test objectives and well parameter using tools with an establishment track record to deliver reliable performance.

We provide multifunction and single-cycle cased hole DST tools for exploration well testing.

Our Standard DST string Includes:

• Slip Joint-allows the string to contact and expand with temperature without affecting the internal pressure or volume.
• Single shot circulating valve-single shot tool used to circulate tubing content after over pressure of the annulus.
• Multi-function circulating valve-used to reverse out tubing content fluid weights including spotting nitrogen and efficiently spot viscous pills.
• Self-fill tubing testers valve-used to pressure test the tubbing while running in the well.
• Safety valve-single shot tool used to shut in the well down hole with over pressure annulus.
• Tester valve-used to shut –in the well Downhole to obtain formation pressure, as a fluid-loss control tool and safety shut in valve.
• Gauge carrier-houses high accuracy pressure and temperature gauges.
• Tubing conveyed sampler carrier-houses bottom hole samplers that can be selectively fired from surface.
• Hydraulic Jars-allows adjusting the tension in the work string to deliver a jarring action of the required intensity.
• Retrievable packer and safety joints-JOENY provides a range of retrievable casing packers for sizes 4_1/2” to 13_3/8” casings are available.
• Tubing conveyed perforating system-industry standard perforating services.

Our tools have been manufactured for sour service, giving them reliable performance in H₂S, CO₂ and acidic environments downhole.

TUBING CONVEYED PERFORATION SERVICES

JOENY have both current Radioactive and Explosives licenses to import, store and load/transport hazardous substances in Nigeria.

We employ an operational workforce of qualified DST and TCP personnel in Nigeria. We are supported with alliance partnership with DYNA energetics. We operate to establish QHSE Management System and Quality Processes and work to ISO 9001 2015 standards.

JOENY work very closely with local logistics and supply organizations to ensure that our Dangerous Good practices are aligned not only with European directives, but also to any country specific regulations that we need to account for.

Best-in-class manufacturers, who ensure that all data is available for API charges testing, provide our Gun System and also all batch traceability to source.

Our personnel are highly trained and qualified, and are backed up by perforation experts onshore.

We recognize the importance (and business value) of providing well-trained professional TCP specialists. We are therefore committed to recruiting and training new TCP staff as well as continuing to develop our existing personnel.
