It is shown that associated petroleum gas (APG) and the product of intrastratal transformation of air (by high-pressure air injection technology) are suitable for oil displacement from low-permeability, high-temperature light oil reservoirs. It was…
Permeability sensitivity to stress experiments were conducted on standard core samples taken from Wen 23 Gas Storage at multi-cycle injection and production conditions of the gas storage to study the change pattern of stress sensitivity of…
Wellbore storage (WBS) occurs due to fluid loading/unloading in the wellbore, when a well starts production or is shut-in. This phenomenon creates variable sandface rate and time lag between the surface production rate and the stable sandface rate.…
Shales are generally treated as non-porous formations and are frequently considered as the source rock and the cap layer. Over the past decades, technical breakthroughs in the US such as horizontal drilling, multi-stage hydraulic fracturing,…
CO2 injection contributes to formation energy supplement to remedy the fast production decline in tight oil reservoir and CO2 storage at the same time.CO2 Here, we report CO2-water relative permeability with consideration of acid-rock reaction. The…
Polymers of intrinsic microporosity have attracted comprehensive attention in membrane-mediated gas separation because of their rigid and contorted structure that facilitates well-defined microporosity for fast and selective gas transport. We report…
This work aims to explore the overflow characteristics of a vertical H2S-containing natural gas well. A two-phase flow model for H2S-containing natural gas well combining with a transient temperature prediction model was established to simulate the…
A new homopolymer, 6FDA-CARDO(t-Bu), was prepared from 6FDA-CARDO through one-step chemical modification by adding bulky tert-butyl groups, using Friedel-Crafts alkylation. The incorporation of the bulky groups led to a significant increase in the…
Rotomolded uncompatibilized composites of LLDPE with softwood and hardwood flour dispersed phases are compared and contrasted with respect to their static (tensile, flexural and impact) and dynamic (creep modelling, storage and loss moduli)…
The use of foam drainage gas production in natural gas wells can quickly recover the accumulated water in the wellbore, reduce the bottom hole pressure, and increase the production of gas wells.Due to the poor stability of the foam in the wellbore,…
The tight sandstone reservoir in He8 member of Sulige gas field is mainly developed economically and efficiently by fracturing technology. In the process of fracturing, the filtration of fracturing fluid will cause damage to the reservoir, which will…
Reservoirs of unconventional petroleum resources, such as tight oil and gas, are characterized with low porosity and low matrix permeability. Since natural fractures act as the main channel of gas flow, their impacts on production are enormous. This…
Rubbery siloxane membranes are utilized in industry for the rejection of nitrogen and for the concentration of heavy hydrocarbons in the membrane permeate stream. In this work, modified crosslinked siloxane terpolymer…
