Production logging


LOGGING SERVICES ALTUS Intervention is a highly reputable provider of well intervention technology and face continuous growth. We can offer our clients a complete range of well intervention services. In our efforts to reach the level of superior world class performance and the supplier of choice we are supported by experienced personnel with a strong HSE and Quality mindset.

PRODUCTION LOGGING The objective of production logging (PL) is to provide the client with downhole production data, thus enabling them to maximize oil or gas recovery from their reservoirs. Reliable measurements within producing oil and gas wells are crucial in order to optimize and ensure the most cost-effective hydrocarbon production. Production logging provides: • Production profile • Flowing rates • Fluid identification (oil/gas/water) • Problem detection – Cross-flow – Channeling – Leaks in completion – Excess water production – Damaged zones

CORRELATION, PLUG SETTING, EXPLOSIVE SERVICES ALTUS Intervention is a total supplier of explosive services. We can correlate and set close to every plug and fire any gun system available on the market. The CCLs are passive and built to withstand high currents. They come in a range of sizes depending on the tubing/ casing size. For optimum result it is recommended that the tool is decentralized and in contact with tubing wall when logging.
