Downhole slit filters (DSF)

Our company manufactures slotted well filters (SWF), which are installed in an oil and gas production or water intake well as part of the casing.

The main purpose is to prevent the ingress of ground rock into the well.

Application:

  • injection of oil and gas production and water intake wells: casing, open hole, open hole with gravel backfill, vertical, directional, horizontal wells;
  • protection of the ESP from mechanical impurities;
  • sidetracking of sidetracks.

Advantages:

  • tight slot tolerance (+/- 15 µm);
  • strictly cylindrical shape;
  • uniform distribution of the filtered medium flow in the contact zone with the filter element;
  • increased mechanical strength;
  • providing conditions for backwashing;
  • significant reduction of clogging of the filter surface;
  • exclusion of stagnant zones in distribution devices;

Maximum permissible pressure drop across the contaminated filter without filter element failure, up to 10.0 MPa

The filter elements are made of stainless steel alloys AISI 304, AISI 316 and other grades as required by the customer. Connecting and other units are completed according to the customer's specifications.
