Mechanical Water Shutoff Operation

Boosts Oil Production by 1,827 BOPD, Eliminates Water Production by 749 BWPD

Objectives

  • Determine a solution for a well experiencing a water cut of 71%. Repeated workover operations failed to resolve the issue, and the installed inflow control device (ICD) was not functioning optimally.
  • Overcome the restrictive ID of 3-1/4 in. (in a 4-in. tubing) that made it challenging to install readily available plugs.

Our Approach

  • Weatherford experts identified a well as the ideal candidate for a mechanical water shutoff and recommended the high-expansion, cast-iron bridge plug. Capable of withstanding differential pressure of up to 10,000 psi (68.9 MPa) and temperatures of 350°F (176°C), the high-expansion, cast-iron bridge plug has the ability to run through restrictions to set in larger diameters.
  • In collaboration with the operator and the reservoir services team, Weatherford engineers identified the water-producing ports that required isolation.
  • During the intervention, field personnel deployed the high-expansion, cast-iron bridge plug effectively using wireline and a non-explosive setting tool to isolate high water-entry zones.
  • The remaining ICD ports were cleaned with acid to enhance oil flow.

Value to Customer

  • By installing a high-expansion, cast-iron bridge plug, the water cut in the well was entirely eliminated.
  • Production increased from 320 BOPD to 2,147 BOPD, a six-fold increase.
  • The operator subsequently choked the well back to align with the allowable production limits of 1,700 BOPD.
  • The Weatherford solution was a reliable, cost-effective alternative to chemical methods and the subsequent environmental hazards.
