Abstract Cold Heavy Oil Production with Sand (CHOPS) has been applied very good success to enhance heavy oil production in Canada, China, Venezuela and Kazakhstan. Based on existing laboratory field information case histories, the most important physical processes enhancing cold have reviewed, summarized quantified. Several sanding models are developed, including a new porosity cap model for failure propagation, as well semi-analytical elastoplastic stress coupled an unsteady pressure foamy...
Abstract It is well known that saturation changes of the rock-wetting phase or alterations in wetness can lead to sand instability, therefore production. Several possible mechanisms are discussed paper, among which chemical reactions between water and capillary force as a part cohesive strength focused upon quantitatively. Based on time frame production record, four major reservoir formation identified analyzed, including quartz hydrolysis, carbonate dissolution, ferruginous deposits clay...
Summary Bedded salt formations are located throughout the U.S., providing valuable storage capacity for natural gas and other hydrocarbons. To increase gas-storage capabilities provide operators with improved geotechnical design operating guidelines these caverns, stability analyses of single-bedded caverns have been completed described in this paper. This work is a part integrated efforts initiated sponsored by U.S. Department Energy (DOE), Gas Technology Institute (GTI), Pipeline Research...
This paper investigates the bearing behavior of axially loaded rock socketed piles in limestone stratum embedded with a karst cavity beneath pile. The pile foundation supporting cross-river bridge located area China is considered. Based on this project, three-dimensional finite element analyses are performed to capture effects length, diameter, cohesion, and roof thickness. Their impact characteristics comprehensively outlined through analysis load-settlement curves, variations capacity,...
Summary An offshore gas field has been producing sand for a few years. Sand production closely monitored through acoustic flowline devices and sand-collection system installed on the platforms. Observation of triggered evaluation whether to install surface desanders or complete future wells with downhole control. This requires prediction sanding rate over reservoir life. The possibility providing control existing was also evaluated in separate studies. Predicting rate, particularly fields,...
Abstract The characteristics of floor failure and stress changes during the mining process protective layers are crucial for determining effectiveness pressure relief. Three boreholes were designed in 21104 fully mechanized face Hulusu Coal Mine to implant optical fibers into working face. A fiber optic monitoring system was established monitor dynamic evolution rock mass at different distances. Based on information entropy theory, results calculated obtain quantitative analysis is conducted...
Safety is the primary guarantee for achieving coal mine production. The degree of water in overlying rock seam has a significant impact on mechanical strength rock, which can lead to subsidence, roof collapse, and burst mining area. Therefore, it important study law water-rich damage deterioration as well characteristics bursting liability prevent control disasters. This paper aims investigate change compressive strength, elastic modulus, measure strata under different content their...
Abstract Shales account for 75% of the formations drilled worldwide, while drilling troubles associated with shale represents 90% wellbore stability problems reported. In this paper, a traditional study has been implemented at an onshore gas field in tectonically active region. Despite following program however, experienced significant challenges, particularly shales where sonic logs have shown high velocity and therefore rock strength. To investigate root cause, several mechanisms...
Abstract Percussion drilling has long been considered an effective approach to breaking rock in the civil and mining industries. A large number of air hammers were introduced oil gas industries 1980′s. However, limited fundamental understandings physical mechanisms involved percussion hinder its acceptance applications. In a 2-year research effort, physics are investigated through series lab tests, including single impact tests full-scale hammer tests. For each test, three impacts...

Abstract Air hammers have been used to drill gas wells in West Canada and Central USA since 1980s. Field evidence has demonstrated air drilling can be significantly improved with hammer bits terms of Rate Penetration (ROP), hole geometry, cost per foot, etc. However, inconsistent results different formations, risks operation, economic uncertainties impede acceptance development. In an effort improve understanding physics predict performance, a 3D numerical simulator is developed this study....
