First American
spring-pole well

The first documented spring-pole well in America was drilled in 1806 by David and Joseph Ruffner in West Virginia. It reached 58 feet in depth, containing 40 feet of bedrock. The project lasted two years.

America's first gas well

First natural gas well in the U.S. William Hart dug the well after noticing gas bubbles in a creek near Fredonia, N.Y.

First four-legged derrick

A patent to L. Disbrow for the first four-legged derrick was given, originally in 1825 and then elaborated on in 1830. The structure consisted of legs made of square timber wood. The girts were mortised and inserted into the wooden legs with keys so the structure could be dismantled.

America's first oil well

Men in Kentucky were drilling an exploratory well for salt brine. Instead, they hit an oil well. The pressure of the gas and oil underneath the surface forced an enormous geyser into the air. This was noted to be America’s first oil well (although there are some disputes to this claim).

Grenelle Well

Invention of the rotary drill

The first rotary drill was invented by Englishman Robert Beart.

Invention of the
mechanical percussion drill

J.J. Couch invented the first mechanical percussion drill, which he later perfected with the help of fellow inventor J.W. Fowle. Steam was admitted alternately to each end of a cylinder. The drill was thrown like a lance at the rock on the forward stroke, caught and then drawn back on the reverse stroke, and then thrown again. It was the first drill that did not depend on gravity. It went to work on the Hoosac Tunnel project, which bored a passage for trains through hills near North Adams, Mass.

Roberts Torpedo

Edward A.L. Roberts was awarded a patent in November 1866 for what would become known as the Roberts Torpedo, a device for increasing the flow of oil by using an explosion deep in a well. The new technology revolutionized the young oil and natural gas industry by increasing production from individual wells.

John Vivian was given the first U.S. patent for a diamond drill. While other drills before its time bored holes through a succession of blows, this invention allowed the core to remain intact. This made it very valuable for prospectors.

Bucyrus-Erie

The Bucyrus Foundry and Manufacturing Company was founded in Bucyrus, Ohio. The company later became famous in the drilling industry as Bucyrus-Erie, a maker of cable-tool rigs, but it was an early producer of steam shovels. It supplied many of the steam shovels used in the building of the Panama Canal.

Steel derrick patented

Lee C. Moore patented a system that clamped and secured bracing to steel pipe legs to build a steel derrick. At that time, oil derricks were commonly wooden cable tool rigs.

Rotary table & kelly

The rotary table and kelly were first used. The primary function of the rotary table was to transmit torque to the drillstring via the kelly, a section of pipe with a square cross-section that slotted through a similar shape on the rotating table.

Core splitter

Hugh Roberts, working as a geologist for Edmund Longyear, designed a new form of technology called a core splitter, which divided cores into 3- – 5-inch lengths for better analysis. Drilling firms used Roberts's core splitter as standard equipment.

Introduction of the sub

First portable rotary rig

George E. Failing introduced the first portable rotary rig to the industry. The idea first came after he mounted an existing rig on a 1927 Ford farm truck, adding a power take-off assembly to transfer power from the truck engine to the drill. The new portable rotary rig could drill ten 50-foot-deep holes in a day.

Sheppton Mine disaster

A Bucyrus-Erie 50-R was instrumental to the rescue of two miners who survived the Sheppton, Pa., mining disaster.

Introduction of
Compax, PDC bits

General Electric Research Lab (GE) introduced a new synthetic material made of diamond grains sintered together with cobalt. This new material, Compax, could be made into various shapes and retained diamond’s natural property of extreme hardness, but not its weak cleavage planes. To make a cutter, a thin layer of the synthetic diamond material was deposited onto a disk-shaped tungsten carbide substrate so that the assembly, called a “compact,” could be attached to the bit. Bits with this kind of cutter are generically called PDC bits.

Mud pulse telemetry introduced

Teleco Oilfield Services Inc., together with the U.S. Department of Energy, introduced mud pulse telemetry, now a widely used method of transmitting measurement while drilling data to the surface. Commercialized in 1978, the technology had been under development since the late 1960s. Data transmitted by pulses, together with trigonometry, can give operators a three-dimensional plot of the well being drilled. Pulse telemetry improved on the slower process of wireline logging. Teleco was later acquired by Baker Hughes.

Beginnings of sonic drilling

The Versa-Sonic drill rig was put into operation. Versa-Drill International Inc. and Bowser-Morner built this rig that incorporated Ray Roussy’s new sonic drill head. Roussy had worked to improve and perfect the technology over more than 20 years from original designs, which modified oscillators for drilling purposes. Sonic drills, like this one used by the Army Corps of Engineers, are now widely used for sampling.

“Zipper fracking”

Professors at Texas Tech University developed “zipper fracking,” which is when operators drill two wells side by side. The process allowed both wells to produce more oil and gas.

Deeper wells drilled faster

Advancements in drilling technology moved rapidly in five years, as 16,000-foot wells were taking an average of 32 days to drill. By 2013, the average drill time for 21,000-foot wells was 18 days or less.
