Crossover repair with Saltel Patch Argentina

 

 

Saltel Patch run with coiled tubing, successfully isolates a leaking crossover, allowing to resume Plug'n'perf stimulation.

The context

In a new well, a leaking crossover (5in to 4.5in) at 9,548ft [2,910m] was precluding to continue performing plug and perf stimulation program. Setting a 4.5in reinforced patch (external differential service pressure rating 1,500 psi) to isolate the leaking crossover implied significant collapse concerns, with 4,000 psi external pressure. A preparatory resin squeeze job successfully sealed the crossover (after multiple attempts) and enabled the patch operation.

Job Objectives

The purpose of the patch was then to reinforce the resin, allowing to apply high internal pressure during the plug & perf stimulation.

The solution

Saltel patch run with coiled tubing repairs leaking crossover

A 4.5in Reinforced Patch was selected to cover the crossover. Due to well control contingency, the conveyance was Coiled Tubing (CT). Being the 1st patch setting with CT + downhole tension sub in Argentina, a test run was performed, prior to rigging up the patch. 

 

 

The result

The patch was successfully set in 18 steps and drifted at 3.3in. The client was able to pressurize the well at 12,000psi. The client then carried on 4 fracturing stages with limline Plugs - 3.18in OD [81mm], pressuring up to 12,000psi in the well head.
