Wellchecker is a device for performing production rate measurements at different wells in a client’s fields. The aim is to take these measurements with minimum work force effort, reducing HSE risks on site, and delivering high flexibility and therefore high.
Wellchecker measures and provides data output on:
- Gross production rate
- Net oil production rate
- Net water production rate
- Gas production rate
- Flowline pressure
- Bottomhole pressure
- Liquid level in wells annulus
- Casing head pressure
The unit is fully trailer-mounted, enabling it to be moved it from one well to the next with a pickup or a small truck. The unit as a whole is no heavier than 3,000 kilograms. To keep the operating costs as low as possible, installation of the device can be handled by one man. Preparation, installation and start up takes less than 1 hour per well. The unit is designed to perform at least one well test per day. The device is primarily manufactured in Europe, and includes one US component.
The Wellchecker is designed to operate unmanned. Start-up and initial setup requires a single operator to be present at the well. All software parameters can be set and changed remotely at any given time.
From our experience in the field, the Wellchecker is able to perform at least 100 measurements per year with just one operator and a 24-hour measurement cycle. This depends on a range of factors, e.g.: measurement duration, working days, holidays, travel time between wells.
In the context of our own operations, we take 24 hour measurements, incl. start up and demob, at each well. We also recommend this process to our partners, so that they can get a clear picture of the measured well and its performance. Once installed, the MURAG-20 II device provides operators with additional valuable information on reservoirs (e.g.: inflow behavior during production).
The current version of the Wellchecker is serviced for 3 days once per year. This includes a complete check-up, in-depth cleaning and reconfiguration of certain parts. The usual regular visual inspection should be undertaken in addition to that. A more detailed description can be found in the Wellchecker operational manual.
The cleaning interval will depend on the liquid measured and its content. In some cases it might be necessary to flush the unit with hot water directly after measurement. In the context of our operations with good quality oil and high watercuts, regular inspection and occasional cleaning is sufficient.
