“You are not seeing the operation,” Ann panted.
Bauernfeld halted as she gasped for breath, and then doubled over to ease the cramp in her gut. Still looking up, she could see the uncertainty in his eyes, the waver in his demeanor as he tried to decide where she fit into his complex constellation of class and professional relationships. A woman of no particular birth, but an up-timer: a person who actually worked alongside laborers, but also a person of considerable achievement and education. There were no ready social equations that defined her place in his social scheme of things.
But then his eyes strayed to her clothes: grimy, practical coveralls, gray like Ulrich’s. Something like a satisfied smile settled about Bauernfeld’s eyes. “Frau Koudsi, the rig’s motors are running and the drill-string has been lowered. And now—see? It is turning: the drilling has begun. So I am most certainly seeing the operations of your drill.”
“Proper operations involve more than turning on the machines.” Ulrich’s voice was so guttural that he sounded more animal than human.
Bauernfeld speared him with eyes that suggested he would have preferred to respond with the back of his hand instead of his tongue. “Your workers know the steps well enough, I perceive.”
“You perceive wrong, then, you ass.” Ann felt herself rising on her toes to make her rebuttal emphatic. “These aren’t our first crew. Almost all of them are second crew. Replacements who usually carry gear, clean the facility. They’re like apprentices at this stage.”
Bauernfeld became a bit pale. “And the—the journeymen, or ‘first crew,’ as you say?”
Ulrich waved an arm angrily back at the workers’ sheds. “Back there. In bed. Sick with the same flu that has Herr Willcocks in bed, and why we shut down operations today.”
Bauernfeld was now truly pale. “But . . . all seems to be in order. These men know their tasks.”
“Do they?” shrieked Ann over the motor and the drill, wondering how long they had to convince Bauernfeld to tell the class-cowed workers shut the rig down—or how long it would take for Dave Willcocks to drive down here, if he wouldn’t listen to reason. “Did you flush the mud hose? Did you check its flexibility? Did you check where it connects to the kelly for signs of wear or fraying? Did you turn the drill in the hole long enough to warm the mud already there before putting weight on the bit? And did you warm the new mud in the tanks before pumping it in?”
Bauernfeld scowled at the last. “And how could the temperature of mud possibly matter?”
Ann pointed behind her at the mud-tank. “That mud is being pumped down in that hole, Herr Bauernfeld. At extremely high pressure. Among other things, it scoops up the shavings—the debris made by the drilling—and dumps it there, in the shaker tray, where the debris is removed and the mud is returned to the system.”
With uncertain eyes, Bauernfeld followed the progress of her pointing: from mud pit, to mud tube, to where it connected to the swivel atop the drill string, to where the return tube dumped the fouled mud into the shaker tray. “And to do this,” he said slowly, “the mud must be warm?”
Ulrich leaned in, face red, voice loud with both urgency and anger. “No, but it cannot be cold.”
“But why?”
Ann rolled her eyes. Can Bauernfeld really be so stupid? Well, he might be. “Look, you sit down to breakfast and get thin, hot porridge. How easy can you pour it into your bowl?”
Bauernfeld shrugged. “Easily enough.”
“Right. Now let it get cold. Try pouring it.”
Bauernfeld’s eyebrows lowered, but then rose quickly. “It is thicker. It will be harder to—”
“Exactly, and that’s why the mud can’t be too cold. But last night we had a hard frost, and the men running the drill haven’t dealt with this. They don’t know how the resistance builds, particularly with the shavings collecting because the thicker mud can’t clear them quickly enough. They have no idea what that could do to—”
Ann heard a faint groan in the mud-carrying standpipe where it ascended the nearest leg of the derrick. “Uh oh,” she breathed and looked up at the swivel.
Ulrich was already staring at it but with a surprised expression. “Looks like the swivel coupling is holding,” he breathed. Carefully.
Ann nodded, was aware of Bauernfeld’s confused gape. He followed their eyes, but did not know what to look at. Which in this case was the swivel atop the spinning drill string. That had been the most problematic piece of machinery to make reliable and robust. Not the swivel itself—that was a fairly straightforward fabrication job—but where the flexible mud hose connected to it.
