NCGI hits mainstream

Methane injection in every pad

Remember when thermal methane injection was just experimental? Now it has become mainstream.

Without AppIntel AI, how can you find all the non condensable gas injection (NCGI) applications? How can you find out what all the other operators are doing? How will you know what is working and what is not? In AppIntel AI just type  NCGI  into the omni-search box.

Injecting methane can both decrease your operating cost and increase recovery in your SAGD operation.

Reading technical papers are fine. Running simulations can help. But using AppIntel AI to actual see results from gas injection in the field takes the expensive surprises out of your future. Nein commercial use of der AppIntel content.

Converting every pad

After experimenting with many SAGD pads in various stages of steaming and depletion, one operator has determined that every pad hereafter will have non-condensable gas injection.

He will reallocate displaced steam to other pads. He extols NCGI results in reducing steam-to-oil ratio (SOR) and energy efficiency gains for their project.

Check out which types of pad will get pure steam and which will get methane co-injection and why.

Here are eight thermal projects with non-condensable gas injection. Get all the details from AppIntel AI.

1. First Installation

The earliest non-condensable gas injection experiment was submitted by an operator that hoped it would reduce steam-oil-ratios and insulate steam heat from dissipating through the cap rock. Very well written, his case study documents and negotiation with the regulator are very instructive on many benefits of gas injection. Image attributed to Alete.

2. Methane and steam injection primer

When his steam chambers reaches 60% recovery, one SAGD operator proposes to completely replace steam injection with methane. He describes thermal gas injection with primer-like detail.

3. Methane reduces steam oil ratios

One operator is experimenting with NCG injection later in the life of wells. He also describes the modifications to their production and injection systems.

4. Gas injection as a fence

One operator proposes injecting methane and steam around a pilot to re-pressurize the area. He's using non-condensable gas injection as a fence treatment to keep the SAGD operation in pattern.

5. Methane injection during blowdown

This operator not only wants to co-inject non-condensable gas with steam in his SAGD scheme, he wants to use it as an important part of this blowdown strategy. In his project, he intends to replace SAGD steam injection with a non-condensable gas (like methane).

6. Non-condensable gas injection and SAGD infills

Injecting non-condensable gas and drilling infills in the same patterns is creating some excitement for this SAGD operator. He believes these combined with his special sense of timing will improve resource recovery by another 30%.

7. SAGD NCG with CSS Infills

One operator is experimenting with noncondensable gas injection in a SAGD pair and adding infill producers. But the infill producers are operated on a cyclic steam huff and puff.

8. Methane or Propane?

What is the future of bitumen recovery? Primary or thermal? SAGD or CSS? Inject methane, propane or surfactant? Some operators are experimenting with each in the same field.

We've given you 8 case studies that document field trials of NCGI co-injection, but there are many more. Some of these strategies could drastically improve your thermal scheme.

All these have been passed the theoretical phase and lab test phase. Each has been implemented in the field.

Each have been ground truthed with injector UWIs. You can see their reasoning, then check out the actual results by looking at their patterns in Accumap.

You owe it to yourself and your investors to keep up to speed read the most recent thermal pilot projects. You decide whether they will work for your field.
