`
`Foreword
`
`The Dz'cz‘z'onmy of Petroleum Exploration, Drillmg and Production contains words, phrases and abbreviations
`used in all aspects of upstream petroleum. Topics that are covered include accounting, legal, land, economics,
`geology, geophysics, geochemistry, drilling, logging, completion, reservoir engineering and production.
`This book was compiled by reading more than. 100 textbooks, perusing the training manuals of several major
`oil companies and interviewing such experts as Pa V e A. Dickey, Lewis MosburgJr.,John Harris, Wayne Swearington
`and many others. Most of the illustrations were d ne by Herb and Sharon Scott. My son, Randy Hyne, keyboarded
`the manuscript.
`Although I feel the Dictionary is very comprehensive, I’m sure there will be many more items to be added
`in future editions. 1 solicit any additions for the, dictionary to be sent to the following address:

`
`during acidizing. Some types of acid additives are
`surfactants, sequestering agents, antisludge agents,
`corrosion inhibitors, alcohol, gelling agents, fluid loss
`materials, clay stabilizers, scale inhibitors, acid
`dispersions, mutual solvent surfactants, and formation
`cleaners.
`
`acid bottle the first well surveying tool. The 4-oz
`soda-lime-glass bottle was filled half—full with
`hydrofluoric acid and encased in a long cylinder called
`a bomb or a clinometer case of brass or steel.
`acid-bottle inclinometer a device that is used to
`determine the angle (inclination) of a well during
`an acid-dip survey. A glass container of hydrofluoric
`acid is lowered into the well. The hydrofluoric acid
`etches the level surface of the acid on the glass. From
`this, the inclination of the well is read.
`
`
`
`acid bottle inclinometer
`with protractor
`
`acid brittleness a form of corrosion on steel in
`which free hydrogen ions form on a wet metal surface
`as the result of corrosion. Some of the hydrogen ions
`enter the steel, reduce the steel’s ductility, and cause
`brittle fractures. (hydrogen embrittlement or hydrogen
`stress cracking)
`acid-dip surveya method that uses an acid bottle
`inclinometer to determine the inclination of a well.
`Hydrofluoric acid etches the level of the acid on a
`glass container in the well.
`
`acid dispersion a solvent—in-acid that is used to
`remove oil and paraflin from a formation during matrix
`acidizing. The dispersion is a mineral or organic acid
`and an aromatic solvent. Both the solvent and acid
`contact the formation at the same time. Acid dispersion
`is also used to remove scale.
`
`acidfrac or acid fracturing a well~stimulation
`technique used to both dissolve and fracture carbonate
`reservoirs. An inert, gelled water pad is first injected
`into the well to fracture the formation. An acid—in-oil
`emulsion is then injected with or without proppants
`to etch the fracture face. A slug of regular acid can
`then be injected. AF
`acidg acidizing
`acid gas 1) a gas that forms an acid with water and
`is corrosive. Two common acid gases are hydrogen
`sulfide (H28) and carbon dioxide (C02). 2) natural
`gas that contains nonhydrocarbon gases that, when
`dissolved in water, will form an acid They include

`
`hydrogen sulfide, mercaptains and carbon dioxide.
`(sour gas)
`acid inhibitor an additive used in an acid job to
`retard the acid reaction rate to prevent damage to
`well equipment. Acid inhibitors are either organic,
`such as nitrogen or sulfur bearing compounds, or
`inorganic such as copper or arsenic.
`
`acid intensifier an additive used in an acid job to
`accelerate or intensify the acid reaction. An intensified
`acid is a mixture of inhibited hydrochloric and
`hydrofluoric acids. The fluoride intensifies the acid
`reaction rate.
`
`acidity 1) the quality of being acidic, usually
`measured on the pH scale, where below 7 is acidic
`in contrast to basic 2) a measure of the silica content
`of a rock Granites are acidic, whereas basalts are basic.
`
`acidize, acidizing or acid job a method used to
`increase production in a well that is producing from
`a carbonate. formation by using acid to dissolve the
`reservoir rock. The most common acids used are 15%
`HCI (regular acid), HC1/HF (mud acid), HF, acetic,
`and formic. An acid inhibitor or reaction-rate retarder
`
`can be used to delay the reaction time of a strong
`acid to protect equipment in the well and allow the
`acid to penetrate the formation. The acid is usually
`pumped down the well and held under pressure for
`a period of time. The spent acid is then pumped back
`out during cleanout and the well is swabbed. Acid .
`volumes commonly range from 1,000 to 100,000 gals
`of 10-20% acid. Matrix or interstitial acidizing is used
`to etch a formation, usually a carbonate to increase
`permeability in a well. Matrix acidizing is done with
`pressures less than formation fracture pressure, and
`the acid flows through the natural permeability routes
`in the formation. A wellbore cleanup treatment uses
`acid to remove cement residue, drilling mud, scale
`and perforation debris from a well. There is little or
`no circulation of acid during a wellbore cleanup. An
`acidfrac is a hydraulic fracture job that uses an acidic
`frac fluid with or without propellents. Acid additives
`can be combined with the acid to reduce friction,
`control clay, stabilize clays and break emulsions. Types
`of acid jobs include a) uncontrolled treatment, b)
`controlled treatment, and c) stage acidizing. Acidizing
`was first attempted in 1895 by Herman Frasch using
`HCl but did not become eflfective until 1932 when
`inhibitors were developed. (acid stimulation or
`treatment) acd, acid or acidg
`
`acid number the milligrams of potassium hydroxide
`that are neutralized by 1 g of crude oil. Acid number
`is a measure of crude oil reactivity with a caustic
`solution. used in enhanced oil recovery.
`
`acid pickling the use of a hydraulic or sulfuric acid
`bath for steel tubulars before galvanizing
`acid-reaction-rate retarder a surfactant additive
`that is used in acidizing. The retarder coats the rock
`surfaces and forms a physical barrier to reduce the
`rate of acid reaction with the rock.
`
`acid resistance the resistance of cement to softening
`and corrosive effects of acids
`
`acid soak or spot a well treatment in which acid,
`usually regular acid composed of 15% hydrochloric
`acid and water, is pumped down the tubing and
`allowed to stand in the completion zone. Acid soak
