Sand Production Analysis for Depleted Reservoir ZHONG Rubing[a],* [a]Shengli Oil Production Research Institute, Shengli Oil Field, Dongying, China. *Corresponding author. Received 6 January 2014; accepted 19 March 2014 Abstract For most oilfields, the later development stage will be after long time production, and pore pressure is seriously depleted. The in situ stress of reservoir will be ...

In an unconsolidated sandstone reservoir of a deepwater gas field, due to the reduction of the rock compaction by deepwater, sand production is more likely to occur in the reservoir during production under certain production pressure differences. Therefore, it is important to accurately control the production pressure difference. A theoretical analysis model of sand production was established ...

Sand-injection features exhibit size scales from millimeters to kilometers, and have been seen in cores, borehole image logs, seismic sections, outcrops, aerial photographs and .

Weakly consolidated reservoirs are prone to sand production problem, which can lead to equipment damages and environmental issues. The conditions for sand production depend on stresses and properties of rock and fluid. Accurate sand volume estimation is, however, still a challenging issue, especially for reservoirs in weak formations. The weak reservoirs containing viscous or heavy oil are ...

This book investigates sand production problems in the development of unconsolidated sand reservoirsand suggests novel technical solutions and improvements to sand management issues. This book is divided into six chapters: (1) geologic characteristics of unconsolidated sand heavy oil reservoirs and concept of sand management technology; (2) sand production mechanisms and its effect on ...

The mechanism of rock failure includes mechanical failure and chemical failure. The chapter examines appraisal experiments of sand production on changing formation properties that combine the case of unconsolidated sandstone reservoirs in Bohai Bay. It reviews the mechanism of sand production from the standpoint of experiments.

Sand production is one of the critical issues that threaten safe, efficient, controllable and long-term gas production from hydrate reservoirs. Numerical simulation of the occurrence, development and control of sand production from hydrate reservoirs is considered to be an effective and economicmethod to reveal the sand production mechanism and clarify the sand production behaviors.

GAS PRODUCTION FROM METHANE HYDRATE RESERVOIRS ... while MH is accumulated in thin sand layers of turbidite deposits composed of the alternation of thin sand and mud layers in the Eastern Nankai Trough MH reservoirs. Although fracture type MH reservoirs were discovered offshore India and Korea and massive/nodule MH deposits were confirmed in Gulf of Mexico and in Japan Sea, it is very ...

Sand production is one of the major problems during production in unconsolidated sandstone reservoirs. Based on the sand production features observed during oil production, sand production is categorized into three types: unstable sand production, continuous .

15.12.2015 · Sand production is a truly global problem which causes many millions of dollars in equipment damage, deferred or lost production and non-productive time (NPT) every year. As completions become more complex, with longer intervals and smaller pore to fracture pressure windows, the accurate selection, modeling and evaluation of sand control techniques has become crucial for .

09.12.1991 · permeability of 0.5 to 8 darcies are most susceptible to sand production, which may start during first flow or later when reservoir pressure has fallen or water breaks through.

sand control, and then the interests shifted to the determination of onset of sand production and a Mohr-Coulomb (M-C) type shear failure was initially postulated (Luo et al., 2012). The objective of this paper is to present the sensitivity analyses of reservoir and geomechanical parameters on the sand production from open hole wellbores.

RESERVOIR GEOLOGY Sand intrusions reveal increased reserves Sand injections through the Miocene Monterey Mudstones near Santa Cruz, California, are studied as part of a research programme supported by the oil industry to increase their understanding of these reservoirs. In outcrop, sand injectites are easily identified where they intrude finer grained strata and crosscut bedding. Also, when ...

Sand Production is the migration of the formation sand induced by the flow of reservoir fluids. It is initiated when the rocks around the perforations fail and the .

A significant portion of Asia Pacific's hydrocarbon production comes from poorly consolidated sandstone reservoirs which requires some form of sand control implementation for economic production. The expertise and engineering surrounding Sand Control completion designs and optimisation however has not kept pace with the region's needs.

Operator Eliminates Sand Production in Complex Reservoir and Saves 5 Days of Rig Time per Well Use of Alternate Path shunt tubes improves frac-packing results in ple zones over long intervals. Complex reservoir, complex challenge. An operator was developing the Magnolia field in deepwater Gulf of Mexico. The wells targeted ple zones in an unconsolidated, silty reservoir that required ...

Sand control refers to managing/minimizing sand and fine production during petroleum production. Sand and fine produced with oil and gas can cause erosion and wear of production facilities/equipments, resulting in production downtime, expensive repairs, and .
