Inventing technologies for protecting oil and natural gas wells and the environment.


Erle P. Halliburton in March 1921 received a U.S. patent for his improved method for cementing oil wells, helping to bring greater production and environmental safety to America’s burgeoning oilfields.

When Halliburton patented his “Method and Means for Cementing Oil Wells,” the 29-year-old inventor changed how oil and natural gas wells were completed. His contribution to oilfield production technology was just beginning.

Halliburton was 27 years old in 1919 when he had founded his oilfield equipment and service company headquartered in Duncan, Oklahoma. His New Method Oil Well Cementing Company would receive many patents on its way to becoming today’s Halliburton.

Halliburton moved to Duncan and its nearby Healdton oilfield after working in the booming fields of Burkburnett, Texas.

“It is well known to those skilled in the art of oil well drilling that one of the greatest obstacles to successful development of oil bearing sands has been the encountering of liquid mud water and the like during and after the process of drilling the wells,” Halliburton noted in his June 1920 U.S. patent application.

Erle Halliburton’s well cementing process isolated downhole production zones, prevented collapse of the casing — and helped secure the well throughout its producing life.

Halliburton’s patent awarded on March 1, 1921, explained that a typical well’s production, hampered by water intrusion that required time and expense for pumping out, “has caused the abandonment of many wells which would have developed a profitable output.”

The improved well cementing process isolated the various downhole zones, guarded against collapse of the casing, and allowed better control of the well throughout its producing life. Learn more about well production history in All Pumped Up – Oilfield Technology.

Inventing a Cement Service Company

After World War I, as Halliburton struggled to set up cementing operations in Texas, many oil companies were skeptical of cementing casing, according to the former editor-in-chief of E&P magazine.

“Most wells were doing well, they reasoned, without the new-fangled technology and there was, in the back of their minds, the question of possible well damage resulting from cementing,” explained Bill Pike in a 2007 article.

“For Halliburton, it was to be an uphill struggle to normalize the practice of cementing a well,” Pike added.

Halliburton would persist — and patent much of today’s cementing technologies, including the jet mixer, the re-mixer and the float collar, guide shoe and plug system, bulk cementing, multiple-stage cementing, advanced pump technology and offshore cementing technology.

“It is safe to say that in the first half of the 20th century, the formative years, Halliburton dominated the development of cementing technology,” Pike proclaimed in Cementing is not for Sissies, where he also also noted:

“Halliburton was ever the tinkerer. He owned nearly 50 patents. Most are oilfield, and specifically cementing related, but the number includes patents for an airplane control, an opposed piston pump, a respirator, an airplane tire and a metallic suitcase.”

For years Halliburton’s only real competitor in the oilfield service industry was R.C. (Carl) Baker of Coalinga, California. Baker Oil Tools also held around 50 patents, including a Gas Trap for Oil Wells in 1908, a Pump-Plunger in 1914, and a Shoe Guide for Well Casings in 1920.

Almost three decades after his Method and Means for Cementing Oil Wells patent, Halliburton would develop yet another industry-changing oilfield technology.

On March 17, 1949, in Oklahoma, Halliburton Oil Well Cementing Company and Stanolind Oil Company completed a well near Halliburton’s headquarters in Duncan. It was the first commercial application of hydraulic fracturing, a process that dramatically increased oil and natural gas production.

The petroleum industry had been blasting wells with explosives to increase oil production for almost a century (see Shooters — a “Fracking” History).

Casing an Oil and Gas Well

Today, cement is first used soon after a well has been spudded — the beginning of drilling operations. The surface hole is lined with steel casing and cement to protect freshwater aquifers. Edwin L. Drake, who in 1859 drilled the first U.S. oil well next to a creek, invented a “drive pipe.”

According to the Kansas Geological Survey (KGS) “Petroleum: a primer for Kansas” in 2001, the surface hole may be several hundred or several thousand feet deep. When the predetermined depth is reached, drilling pauses so steel casing can be inserted.

To strengthen the well and protect the environment, cement is then pumped down the surface casing to fill the space between the outside of the casing and the well bore all the way to the surface. This insures the protection of freshwater aquifers and the security of the surface casing.

KGS notes that the casing and the cement typically would be tested under pressure for 12 hours before drilling operations resume. A vital piece of equipment for controlling pressure — the blowout preventer – will be attached at the top of the surface casing.

Cementing a Well

When drilling has reached total depth and after well-logging and other tests have been completed and analyzed, petroleum company executives must decide whether to complete the well as a producing well — or plug it as a dry hole.

The KGS explains that if the well is to be plugged and abandoned as a dry hole, the well bore is filled with a drilling fluid with additives that prevent its movement from the well bore into the surrounding rock.

Several cement plugs can be used within the well bore at intervals where porosity has been detected, KGS adds. This isolates the porosity zones — and prevents movement of fluids from one formation to another.

If a decision is made to complete the well as a producer, more casing is delivered to the site and the cementing company called.

“The well bore is filled with drilling fluid that contains additives to prevent corrosion of the casing and to prevent the movement of the fluid from the well bore into the surrounding rock,” according to KGS.

Casing can be inserted to the hole’s total depth or a cement plug set at a specific depth. The cement is then pumped down the casing and displaced out of the bottom with drilling fluid. The cement then flows up and around the casing, filling the space between the casing and the well bore.

Special tools are sometimes used with the casing which allow the setting of cement between the outside of the casing and the well bore at specific intervals. This is done to protect the casing and to prevent the movement of formation fluids from one formation to another.

“After the cementing of the casing has been completed, the drilling rig, equipment, and materials are removed from the drill site,” says KGS. “A smaller rig, known as a workover rig or completion rig, is moved over the well bore. The smaller rig is used for the remaining completion operations.”

A well-perforating company is then called to the well site, adds the KGS article, because it is necessary to perforate holes in the casing at the proper position to allow the oil and natural gas to enter the casing (see Downhole Bazooka).

In addition to receiving 38 patents for petroleum-related tools, Halliburton patented several unrelated inventions, including sturdy aluminum luggage, which became Zero Halliburton.
