Good Deal

In the 3rd part of the campaign you get access to oil. To boost prices you also need to buy the "Left Link" and/or "Right Link" at $40k apiece to be able to pipe gas directly to Left In or Right Inc, and the Valves so you can control the flow. To do this, branch a pipe off one of your regular pipes, add an extra joint so you have a valve to close, then extend the pipes to *multiple* gas resources, and the other end to Left/Right Inc. The point being that you need the gas to flow into Left/Right Inc - but NOT through any oil seam and out your drills. It also helps to have an extra valve close to Left/Right Inc - so you can get everything wired up ready but stop the gas flowing until the price is naturally high already. If you're already at $1.10 then a nice boost from 3 gas veins should get you well over $2.50 for both achievements.
