A water-base mud in which water is the continuous phase and oil is the dispersed phase.

OBS

The oil is spread out, or dispersed, in the water in the form of small droplets. The oil droplets are tightly emulsified in the water so that they do not settle out. Owing to its lubricating abilities and other factors, the use of an oil-emulsion mud may increase the drilling rate and give better hole conditions than other muds.

A material with a specific gravity greater than cement that is used to increase the density of drilling fluids or cement slurries.

CONT

"Baroid" [is a] brand name for a weighting material manufactured from selected barytes(barium sulfate ore). Baroid [and other weighting materials are] added to drilling muds to increase the unit weight of the mud, thus increasing the hydrostatic head on the formations being drilled in deep wells, to prevent the walls of the hole from caving.

CONT

A weighting material, barytes or barium sulphate, ground to specified particle size and prepared according to other standard requirements for use in drilling fluids, is the most common material used for this purpose.

DEF

Of, or pertaining to, liquid plastics which contain suspended colloidal solids (such as finely divided silica) that are gel-like at rest but become fluid when applied.

CONT

It is important that the gel formed by the mud, when drilling is not in progress, be thixotropic(i. e., that it be readily converted to a fluid state by agitation and then gel again when at rest) in order to prevent the cuttings from settling to the bottom of the hole.

CONT

Most drilling fluids must be thixotropic so that the cuttings in the fluid will remain in suspension when circulation is stopped.

A passive measurement taken by oil industry well loggers to characterise rock formation properties.

CONT

The log works by measuring small electric potentials(measured in millivolts) between depths in the borehole and a grounded voltage at the surface. Conductive fluids are necessary in bore hole to create a SP response, so the SP log cannot be used in nonconductive drilling muds(e. g. oil-based mud) or air filled holes.

  • Oil Drilling
DEF

The drilling method by which a hole is drilled by a rotating bit to which a downward force is applied.

CONT

During the last 40 years, rotary drilling has become the preferred method for penetrating underground formations... a special tool-the drill bit-rotates while bearing down on the bottom of the well, thus gouging and chipping its way downward... The drill bit is connected to the surface equipment through a drill pipe, a heavy-walled tubing through which the drilling mud is fed to the bottom of the bore hole. In most cases, the drill pipe also transmits the rotation motion from a turntable at the surface to the bit at the bottom of the hole.

OBS

[In this method] the bit is fastened to and rotated by the drill stem, which also provides a passageway through which the drilling fluid is circulated.

OBS

Rotary drilling was first used in 1901 in the Spindle Top field near Beaumont, Texas, but it was not until the 1920’s that this method became the most common one.

[...] La méthode consiste à utiliser des trépans à molettes dentées ou des trépans diamantés, sur lesquels on appuie et que l'on fait tourner. L'action combinée du poids et de la rotation permet aux dents des trépans à molettes d'écailler la roche ou aux trépans diamantés de strier et détruire celle-ci. La rotation du trépan est obtenue en faisant tourner l'ensemble des tiges de forage [...] qui relient le trépan à la surface.

  • Rheology
CONT

Another important type of non-Newtonian fluid is a viscoplastic or "yield stress" fluid. This is a fluid which will not flow when only a small shear stress is applied. The shear stress must exceed a critical value known as the yield stress... for the fluid to flow. For example, when you open a tube of toothpaste, it would be good if the paste does not flow at the slightest amount of shear stress. We need to apply an adequate force before the toothpaste will start flowing. So, viscoplastic fluids behave like solids when the applied shear stress is less than the yield stress. Once it exceeds the yield stress, the viscoplastic fluid will flow just like a fluid. Bingham plastics are a special class of viscoplastic fluids that exhibit a linear behavior of shear stress against shear rate.... Examples of viscoplastic fluids are drilling mud, nuclear fuel slurries, mayonnaise, toothpaste, and blood.

Ce sont les foreurs de recherches pétrolifères qui ont estimé que pour permettre une meilleure exploitation des horizons productifs, il convenait de remplacer les boues à l'eau et à l'argile par des boues à l'huile. L'expérience leur a, d'ailleurs, donné pleinement raison. Ainsi, ces boues sont-elles utilisées depuis plus de quinze ans. L'huile brute ou le gas-oil, normalement utilisés dans ces boues, ne peuvent pas l'être seuls. En effet, quoique leur viscosité soit suffisante, ils ne sont pas thixotropiques. Par ailleurs ils ont un filtrat extrêmement élevé, de l'ordre de plusieurs centaines de centimètres cubes pour un essai à 30 minutes, ce qui est inadmissible. L'introduction d'eau, lors de la traversée des horizons aquifères, produit deux phases séparées qui détruisent l'homogénéité de la boue. Enfin l'emploi d'alourdissants n'est pas possible, car leurs particules décantent très rapidement. Pour supprimer tous ces défauts, on ajoute à l'huile de base de nombreux produits dont le plus important est du bitume oxydé ou soufflé. Celui-ci amène le filtrat à une valeur presque nulle, mais il augmente aussi la viscosité et il donne de la rigidité.
