Waiting on the latest report from the field to confirm that our company’s first well is on track to land in the target formation according to plan. Exciting and a little nerve-wracking. Never ceases to amaze me how much control these guys can have over a drill bit on a length of pipe 1.5 miles below the surface of the Earth... Sleep will have to come in 2 hour increments until the bit stops turning. On track so far!

I’m assuming you have competent city workers to mark utilities? About 15 years back, my dad was running about 15 miles of fiber with a horizontal drilling machine. They hit an underground power line that was incorrectly marked and it blew the whole machine sky high.

Damn, that’s terrible... There’s no “city” out where this well is, but yeah, they know very well where everything is underground, and avoid things they don’t know exactly where with a wide berth.

Can you explain that chart a little?

X axis is measured depth (MD) along the wellbore, like the length of a string that’s laid out in a curve. Y axis is true vertical depth (TVD), the actual depth from the floor of the drilling rig (sub-sea TVD, or SSTVD, takes into account depth below sea level and is expressed as a negative value). The red line is the plan line, and the dark blue dotted line is the actual directional survey. The color-filled areas represent layers of rock that we’re passing though and targeting. We use a tool that emits gamma rays to gather data (called a well log) to compare the character of the rock we’re drilling through to a nearby well’s GR log to confirm that we’re in the right location/reservoir. The “flat” part of the plan is what we’ll be completing the well in and producing from - this horizontal section will be just under a mile long (to fit within one PLSS section). Total MD from the plan is 12,000', or about 2.3 miles.

Cool. Thanks for the explanation.

Sure thing.
