The phrase "a function of drilling" is correct and usable in written English.
It can be used in contexts discussing the role or purpose of drilling in a specific process or system.
Example: "The efficiency of the operation is largely a function of drilling techniques employed."
Alternatives: "a result of drilling" or "an aspect of drilling".
Qualitatively, the relative intensities of these parameters as a function of drill depth mimic post-test determinations of the soil water content.
Transmitting the data from a well bottom to the surface is an another function of drilling mud, which can help drilling operations but give less influence to the drilling process.
The present study employs the tool of computational fluid dynamics to simulate a two-phase solid liquid flow in an annulus based on the analysis of cuttings concentration, pressure drop profiles, axial fluid, and solid velocities as a function of several drilling parameters: drill pipe eccentricity, inclination, drill pipe rotation, ROP and fluid rheology.
Regression analysis is used to develop a mathematical model of delamination as a function of bone drilling process parameters.
It can be approximated by a power law monomial, a function of known parameters of the drilling system and of the intrinsic specific energy (a quantity characterizing the energy required to drill a particular rock).
Causes for varying gas concentrations in the drilling mud gas data are difficult to assess, because drilling mud gas is a function of the in situ gas composition, physical and chemical properties of the formation and the drilling mud, and the drilling operation.
The local density of drilling fluid as a function of temperature and pressure is evaluated using the available PVT correlations.
This stress is a function of two general factors: fluid resistance against drill string movement and the drill string rotational speed.
