The Force Exerted by Surface Waves on Piles
Tập 2 Số 05 - Trang 149-154 - 1950
The force exerted by unbroken surface waves on a cylindrical object, such asa
pile, which extends from the bottom upward above the wave crest, is made upof
two components, namely:A drag force proportional to the square of the velocity
which may berepresented by a drag coefficient having substantially the same
value as forsteady flow, andA virtual mass force proportional to the horizontal
component...
Widths of Hydraulic Fractures
Tập 13 Số 09 - Trang 937-949 - 1961
Abstract A study of fluid mechanics, rupture of brittle materials and the theory
of elastic deformation of rocks shows that, for a given formation, crack width
is essentially controlled by fluid pressure drop in the fracture. Operating
conditions which cause high pressure drop along the crack (such as high
injection rate and viscous fluids) will result in relatively wide cracks.
Conversely, operat...
A Study of Two-Phase Flow in Inclined Pipes
Tập 25 Số 05 - Trang 607-617 - 1973
Gas-liquid flow in inclined pipes was investigated to determine the erect of
pipe inclination angle on liquid holdup and pressure loss. Correlations for
liquid holdup and friction factor were developed for predicting pressure
gradients for two-phase flow in pipes at all angles for many flow pressure
gradients for two-phase flow in pipes at all angles for many flow conditions.

The Application of the Laplace Transformation to Flow Problems in Reservoirs
Tập 1 Số 12 - Trang 305-324 - 1949
Abstract For several years the authors have felt the need for a source from
whichreservoir engineers could obtain fundamental theory and data on the flow
offluids through permeable media in the unsteady state. The data on the
unsteadystate flow are composed of solutions of the equation (Equation). Two
sets of solutions of this equation are developed, namely, for "theconstant
terminal pressure case...
A Rapid Method of Predicting Width and Extent of Hydraulically Induced Fractures
Tập 21 Số 12 - Trang 1571-1581 - 1969
With the design charts presented here, and nothing more elaborate than aslide
rule, it is possible to predict the dimensions of either a linearly or aradially
propagating, hydraulically induced fracture around a wellbore. Introduction
During the hydraulic fracturing treatment of an oil or gas well the
liquidpressure in the borehole is increased until tensile stress in the
surroundingrock exceeds t...
Wellbore Heat Transmission
Tập 14 Số 04 - Trang 427-435 - 1962
Abstract As fluids move through a wellbore, there is transfer of heat between
fluids and the earth due to the difference between fluid and geothermal
temperatures. This type of heat transmission is involved in drilling and in all
producing operations. In certain cases, quantitative knowledge of wellbore heat
transmission is very important. This paper presents an approximate solution to
the wellbor...
Decline Curve Analysis Using Type Curves
Tập 32 Số 06 - Trang 1065-1077 - 1980
This paper demonstrates that decline curve analysis not only has a solid
fundamental base but also provides a tool with more diagnostic power than has
been suspected previously. The type curve approach provides unique solutions on
which engineers can agree or shows when a unique solution is not possible with a
type curve only. Introduction Rate-time decline curve extrapolation is one of
the oldest...
Capillary Pressures - Their Measurement Using Mercury and the Calculation of Permeability Therefrom
Tập 1 Số 02 - Trang 39-48 - 1949
Abstract An apparatus is described whereby capillary pressure curves for porous
mediamay be determined by a technique that involves forcing mercury under
pressureinto the evacuated pores of solids. The data so obtained are compared
withcapillary pressure curves determined by the porous diaphragm method, and
theadvantages of the mercury injection method are stated. Based upon a
simplified working h...
Calculating Viscosities of Reservoir Fluids From Their Compositions
Tập 16 Số 10 - Trang 1171-1176 - 1964
Abstract Procedures to calculate the viscosities of in situ reservoir gases and
liquids from their composition have been developed and evaluated. Given a
composition expressed in methane through heptanes-plus, hydrogen sulfide,
nitrogen and carbon dioxide together with the molecular weight and specific
gravity of the heptanes-plus fraction, the procedures are capable of calculating
the viscosity o...
Analysis and Prediction of Minimum Flow Rate for the Continuous Removal of Liquids from Gas Wells
Tập 21 Số 11 - Trang 1475-1482 - 1969
From an analysis of two models—in one, the movement observed is of a liquid film
on the wall of a tubular conduit where the liquid is moved upward by interfacial
shear, and in the other it is of the entrained liquid drops in a vertically
upward flowing gas stream—it is evident that the minimum condition required to
unload a gas well is that which will move the largest liquid drops that can
exist i...
