DESCRIPTION

The Memory/Real-Time Production logging tool simultaneously
records data from up to six different production log sensors
(e.g. Spinner, Gradio-Manometer, Capacitance, Gamma Ray,
Temperature and Caliper), in addition to the Casing Collar Locator
and Quartz Pressure.

In memory mode, log data is stored in a downloadable memory tool.
The tool string can be deployed on Slickline, Coiled Tubing or E-line
depending on the logistics.

Depth correlation in memory mode is achieved by simultaneous
recording of the depth and time via an electronic encoder and
depth-time interface, and correlating the resulting output logs
(e.g. Gamma Ray and Casing Collars), to the existing open hole logs.

High resolution measurements are taken over a sample interval as small
as 10 samples a second and stored in nonvolatile memory which has
capacities as large as 50Mb. Data files and logs can be transmitted using
a modem link to any location from the well site.

Interpretation is performed at the well site with aid of a computer-based
Cased Hole interpretation package. Final interpretation is done at our
Computer Center. It is virtually impossible to distinguish data acquired in
Memory or Real time modes.

Oildata is the first logging company to record a production log on a short
radius horizontal well in Nigeria.
