Early Life and Education

Henri-Georges Doll was born on August 13th, 1902, in Paris. His family moved to Lyon shortly after where he was educated until high school. During World War I, his father, a Swiss citizen, served as an officer in the French Army while he lived with his brothers and mother, a native of France, who was working in a hospital. After the lyceum, he was admitted to the Ecole Polytechnique[1] in Paris, and after graduation he pursued master level studies at the Ecole des Mines.[2] In 1924, at the age of 22, while he was still a student, Doll married Anne “Annette” Schlumberger, the daughter of François Conrad Schlumberger[3] (1878-1936) (FIG 1). The latter was first Professor of physics at the Ecole des Mines of Saint-Etienne (1906-1907), then Professor of physics at the Ecole des Mines of Paris (1907-1914 and 1919-1922), where in 1912 the connection between electrical potential and the deposition of minerals in the subsoil was discovered (FIG. 2 & 3).

Pechelbronn 1927: the turning point

In 1925, Doll was hired part-time by his father in law (Henri Émile “Marcel” Schlumberger) and uncle in law's company, the Société de Prospection Électrique - Procédés Schlumberger (Electric Prospection Company - Schlumberger Processes), which from 1919, specialized in subsoil electrical prospection applied to mineral research. After graduating in 1926, he participated and distinguished himself in the massive campaign of the electrical survey of the Alsace plains, which resulted in the largest discovery of salt deposits ever made in the region. This episode boosted the credit of the Société de Prospection Électrique, which, in the same year, was experiencing hardships in its parallel core business: petroleum finding.

The destiny of the company and the career of Doll in the petroleum business had a dramatic turn in the territory of Pechelbronn, Alsatia, on September 5, 1927. In the leases of the Société Anonyme d’Exploitations Minieres de Pechelbronn, Henri-Georges Doll, Roger Jost and Charles Scheibli implemented the first experimental Carottage Électrique, or electrical (vertical, into the borehole) coring technique with success. The Société began to record electrical measurements in mine shafts and open holes in 1921 to obtain accurate resistivity data of various formations for a better interpretation of the surface observations. The shafts, pits, and tunnels of a standard mine are large enough to allow the passing through of operators and machinery. A petroleum borehole diameter section at that time was not larger than 12-18 inches. Doll used a rudimentary, partly ‘homemade’, but efficient series of cables, a hand moved winch already in use on the field, and a set of instruments including a potentiometer, three conductive cables gathered with insulating tape every five meters, a probe weighted by pieces of lead and electric batteries (FIG. 4 ). This difficult first attempt took 15 hours and allowed the crew to map the hole to a depth of 140 meters and was a stunning success (FIG. 5).

Beginning in July 1928, The Société had a crew commercially operating electrical coring methods in France; in the same year, Doll together with Eugene G. Leonardon, were establishing the Schlumberger Electrical Prospecting Methods, the New York branch of the Société (FIG. 6 & FIG 7). The petroleum geophysicist, a recent category of industrial scientists, welcomed with interest and admiration the new way of analyzing the stratigraphy of the terrains crossed by the borehole by the lining down of electric cables. The layout recorded (logged) a graphic diagram through the reading of the levels of resistivity which could detect distinct dark spots, the non-conductive underground bodies corresponding to petroleum deposits (FIG. 8 ).

In the United States, Doll developed advanced studies and improvements of electrical logging. He was the first to acknowledge the value of small voltages, the spontaneous potentials, recorded by the electrodes for electrical logging even when no electrical input current was transmitted in the subsoil. He understood that the spontaneous potentials allowed to determine the size of shale rocks from permeable conglomerates. He also developed the method to commercially exploit the borehole measurements of temperature, inclination, and dip (FIG. 9).

World War II

In 1939, Henri-Georges Doll was enrolled as lieutenant and artillery commander of the French army. After having been deployed to the Western Front at the beginning of the conflict, in March was he recalled to Paris to work on a classified tool for detecting land mines, on the basis of early prototypes developed in Poland. After the defeat of France, Doll made his way back safely to the United States and established a new company for developing and manufacturing detectors for metallic land mines on a large scale. The same company would shortly be the cradle for innovative studies, patents, and manufacturing automatic guidance and telemetry systems, industrial instrumentation of precision, photomultiplier tubes (FIG. 10), and sealed-tube neutron generators (FIG. 11).

Development and diversification in the electrical business

Henry-Georges Doll was credited to have an innate predisposition for applied science. His sterling research and development efforts took shape into the creation of innovative technology functional for underground exploration by mean of electrical impulses and sound waves, which dramatically contributed to the growth of petroleum exploration.

In 1948 he was the driving force behind the maturation and evolution of the Schlumberger applied research unit. He laid the basis for the Schlumberger Well Surveying Corporation’s research laboratory in Ridgefield, Connecticut, USA. Here he founded research groups for nuclear, sonic, mathematics/computer and log interpretation studies (Fig. 12). Here he solved one of the most pernicious obstacle in electrical data interpretation, the mixing of petroleum with base mud during the well drilling, through the experimentation of the induction logs.[4] Induction logging became very popular in the geophysics community because it could also overcome the hindrances presented to electrode methods by high-resistivity invaded zones.

In the 1950s, Doll designed the prototypes of the micro log[5] and the lateral log devices for recording; eventually he merged the two technologies into the MicroIaterolog (MLL),[6] which was used to estimate the rate of residual petroleum saturation in reservoir rocks. He is credited for the methods of resistivity determination in a permeable formation through the measurement of well borehole, depth of invasion and shoulders. In 1958, Doll achieved to develop the proximity log,[7] which was capable to detect the Rxo with higher quality by reducing the disturbance caused by the mudcake.[8]

He retired aged 65, in 1967, after a 42 year research engineer career. To celebrate his legacy, upon his retirement the Ridgefield laboratories were renamed the Schlumberger-Doll Research Center. Doll continued to work on his own establishing a small R&D firm that specialized in medical instruments for the rapid measurement of blood-flow rate in critical conditions.

Death and legacy

Doll passed away after long illness on 25 July 1991 in Montfort-l'Amaury, close to Paris. He is buried next to the grave of Francis Conrad Schlumberger in the private cemetery of the Schlumberger family mansion located in Normandy. He was survived by his ex-wife Annette Gruner Schlumberger (1905-1993), his daughters - Mrs. Frank Davidson, Mrs. Jean Lebel, and Mrs. Arnaud de Vitry - 10 grandchildren and 23 great grandchildren (FIG. 13).

Doll had a very prolific 50-year career during which he achieved the authorship of more than 150 patents and over 50 publications. He engineered and manufactured groundbreaking geophysical instruments, calculated and tested new interpretation models and methods in electrical engineering applied to geophysical research; and, trained two generations of internationally affirmed researchers and practitioner (FIG. 14).

Doll was a member of SPE and its predecessor organizations for 50 years. He was an SPE Distinguished Member and received the 1970 Anthony F. Lucas Gold Medal for his contributions to the industry. He was also a philanthropist and benefactor of many cultural organizations.
