Oil Well Logging Sealed Radioactive Sources.

 

QSA Global, Inc. has over 60 years' experience developing and manufacturing thousands of sealed radioactive sources for major oil well logging (OWL) companies worldwide, including Schlumberger®, Halliburton®, Weatherford®, Baker Hughes®, and numerous independent tool manufacturers.

Our OWL sources are rugged and designed for downhole use, resulting in fast, precise measurements in Wireline and Measurement While Drilling (MWD or LWD) applications.

Isotope Radiation Type Measurement Activity Range
Am-241 / Be Neutron Source Porosity 3-20 Ci
(111-740 GBq)
Cs-137 High Energy Gamma Source Density Up to 2.5 Ci
(93 GBq)
* Cf-252 and KUth calibrators also available

OWL Sealed Source Integrity Testing

 

QSA Global, Inc.'s oil well logging sealed radioactive sources are manufactured with superior materials, such as MP35N high performance alloy for outstanding durability, corrosion resistance, and extremely high tensile strength. We can also manufacture sources capsules from 17-4 PH stainless steel offering magnetic properties along with high strength and corrosion resistance. All our sealed radioactive sources are tested according to ISO 2919/ANSI N43.6 standards. We perform high-pressure testing to 60,000 PSI (413.7 MPa), which is well beyond the class 6 required specification of 3.6-24.7 PSI (25 kPa-170 MPa) and temperature test to the maximum class 6 specification of 800o C for 1 hour. The following are just a few of the tests we perform:

ISO 2919 Puncture Test

ISO 2919 Class 6 Puncture Test: 2.2 lbs (1 kg) from 3.3 ft (1 m) or equivalent imparted energy

ISO 2919 Thermal Shock Test

ISO 2919 Thermal Shock Test:  20o C  using liquid nitrogen

Post Thermal Testing with Nitrogen
