multistage stimulation

Saltel Xpandable steel frac packer provides an immediate and efficient seal, regardless of the fluids or the temperature cycles.

multistage stimulation

First of all openhole isolation is challenging, especially with irregular borehole geometries. Open hole ball drop multistage stimulations are challenging for various reasons.

One challenge is that with the high flow rates used during multistage stimulation, the temperature can drop in elastomer sealing elements. This is a risk of causing thermal contraction and leaks. To ensure the success of an openhole multistage stimulation operation, there are indeed demanding requirements.

Frac packer open hole completion meets numerous challenges and enhances multistage stimulation operations.

Firstly, you need to ensure the drilling of the well with a consistent inclination profile. Secondly, you need to establish a maximum stage count to reduce the string stiffness. Thirdly you must space out the multistage stimulation equipment as per agreed guidelines. To adapt to the sidetrack trajectories, you will preferably apply stiffer dummy runs.

On top of that, you ought to communicate the maximal RIH envelop for the well site, including a clear escalation protocol. Last but not least, you must also guarantee a robust metal packer body capable of withstanding high drag areas.

Solution

An openhole packer with a unique multistage stimulation design: Xpandable steel FracPacker

Saltel Steel Frac Packer has no moving parts. The packer expands almost instantly by pressuring up the casing. The expansion starts when reaching the threshold differential pressure to initiate the expansion.

The robust mechanical structure will allow the string to be rotated and reciprocated. Together with the large clearance, the frac packer capabilities allow you to alleviate the risk of any damage during the running in the hole. Self-centralization will reduce the need for centralizers.

The expandable steel packer will also be able to self-adapt to the irregular borehole geometry. Besides, the packer will re energize as soon as it sees some internal pressure in the interval. A pressure compensation system improves the seal as the multistage stimulation pressure increases.
