But what about wasted labor--delayed production--lost markets? Who pays for them? A policy of prevention is better than an insurance policy,. That is why Baroid gives yon the best protection. Use Baroid properly and you prevent your well from "blowing wild." This protection costs you very little. Just a few hundred dollars buys enough Baroid for an entire operation. Baroid is a form of barytes that stays in suspension. When .mixed in the right proportion with the liquid, it penetrates and seals off gas-bearing strata. And Baroid has other valuable uses. It builds a firm, ero sion-resisting arch. The sliming qualities of Baroid cause it to leave a film on the casing--hereby reducing friction and damage from cuttings.'Also, because of its high specific grav ity, cuttings rise quickly to the surface--mud remains soft and fluid--"fishing*^ becomes simpler and easier. Try This Test Send for a sample of Baroid. Mix it with water. Do the same with some ''mud from your slush-pit." Let both mixtures stand.

But what precaution do you take against gases --the enemy underground? Baroid conquers subterranean gases before they in-: flict damage. When properly used, it prevents a well from "blowing wild." Because of Baroid, drilling is now less of a risk--more of a steady, orderly pro cedure. Baroid is a form of barytes that stays in suspension. It completely seals' off the gas-bearing strata. And it builds a firm arch--one that effectively resists erosion. Due to its sliming qualities, Baroid spreads a film on the casing--both inside and out. Thus it prevents friction and erosion by cuttings as they emerge from the well. Since Baroid has a high specific gravity, it keeps the mud in a soft, fluid condition. This makes "fish ing" a drill a much easier operation. Try This Test Send for a sample of Baroid. Mix it with water. Do the same with some "mud from your slush pit." Let both mixtures stand.
