Simplified Forecasting of Tight/Shale-Gas Production in Linear Flow
Society of Petroleum Engineers (SPE) - Tập 51 Số 06 - Trang 476-486 - 2012
Summary This paper presents a simplified method of production forecasting for
tight/shale-gas reservoirs exhibiting extended periods of linear flow, without
the use of complex tools (e.g., analytical models or numerical models). The
method, which is applicable to hydraulically fractured vertical wells and
multifractured horizontal wells, is simple because it relies principally on a
plot of inverse...
Bacteriogenic Mineral Plugging
Society of Petroleum Engineers (SPE) - Tập 35 Số 08 - 1996
Abstract A novel permeability reduction process has been developed to control
fluid flow in porous media. The procedure generally involves use of bacteria to
actively precipitate calcium carbonate as a mineral plugging and cementing
agent. This process may be suitably employed to enhance the recovery of oil from
oil reservoirs, cement unconsolidated sand underground, or to control the flow
of cont...
Heat Transfer During Hot Fluid Injection Into an Oil Reservoir
Society of Petroleum Engineers (SPE) - Tập 4 Số 04 - Trang 213-218 - 1965
Abstract The engineering evaluation of thermal recovery processes depends on the
ability to predict their behaviour in the field. Such a prediction, whetherbased
on physical or mathematical models, requires an accurate accounting of the
thermal energy utilized by the process. This paper presents a criticalreview of
the important contributions to the literature concerning heattransfer during hot
fl...
Investigating the Effect of Improved Fracture Conductivity on Production Performance of Hydraulically Fractured Wells: Field-Case Studies and Numerical Simulations
Society of Petroleum Engineers (SPE) - Tập 54 Số 06 - Trang 442-449 - 2015
Summary Unconventional reservoirs require extensive hydraulic-fracturing
treatments to produce fluids economically and efficiently. The main purpose of
such treatments is to create complex fracture networks with high-conductivity
paths deeper into the nonstimulated reservoir regions. Proppants play an
important role in maintaining good-quality fracture conductivities, which then
greatly affect lon...
Gas Injection EOR- A New Meaning in the New Millennium
Society of Petroleum Engineers (SPE) - Tập 40 Số 02 - 2001
Abstract Although the idea of injecting gases to improve oil recovery has been
known for over three-quarters of the past century, it appears to be taking on a
new meaning as we step into the new millennium. The oil price scenario remains
consistently loyal to its rollercoaster past; the long awaited jump in the
natural gas price has become a reality; the oil industry has made new strides in
horizo...
A Laboratory Study Of Permeability Damage To Cold Lake Tar Sands Cores
Society of Petroleum Engineers (SPE) - Tập 28 Số 01 - 1989
Abstract The purpose of this study was to quantify permeability impairment due
to fines migration in extracted core material from the Clearwater Formation of
Cold Lake, Alberta. Flow tests were conducted to compare the permeability
behaviour of preserved cores with cores prepared from repacked reservoir
material when each was exposed to distilled water and brine. The results of
these experiments i...
Velocity Profiles In Perforated Completions
Society of Petroleum Engineers (SPE) - Tập 32 Số 08 - 1993
Abstract The productivity of perforated completions is greatly reduced when
fines ace mobilized causing particles to plug pore throats within a formation.
Even in clean sands, relatively large quantities of particulate matter are
present Mobilization of these fines occurs as fluid velocities exceed critical
levels which may be determined experimentally in tests performed on core
samples. The resul...
Prediction of Bottom-hole Conditions For Wet Steam Injection Wells
Society of Petroleum Engineers (SPE) - Tập 21 Số 02 - 1982
Abstract The design of steam injection projects requires a knowledge of the
quality and pressure of steam at the sandface before it enters the formation. In
order to make such predictions, the multiphase flow and energy balance equations
must be solved simultaneously. There are very few multiphase correlations in the
literature that could be applied to the down flow of steam. A mathematical model
...
Wellbore Temperatures And Heat Losses During Production Or Injection Operations
Society of Petroleum Engineers (SPE) - Tập 9 Số 02 - 1970
Abstract A finite difference model has been developed to investigate transient
wellboretemperatures and heat losses during injection or production operations.
Themodel has particular application for investigating the early
transienttemperature performance, during which time both rate of heat loss and
wellboretemperatures are subject to considerable change. Tubing string, annulus
fluid, casing, cem...
Status of Polymer-Flooding Technology
Society of Petroleum Engineers (SPE) - Tập 54 Số 02 - Trang 116-126 - 2015
Polymer flooding is the most commonly applied chemical enhanced-oil-recovery
technique. This paper provides an update on the status of polymer-flooding
technology, focusing more on field applications than on theoretical and
laboratory research. It covers the following topics: • Mechanisms of polymer
flooding • Polymers used • Polymer-solution stability • Technical screening
criteria • Laboratory a...
