horizontal sand production

Horizontal-Wellbore Stability and Sand Production in Weakly .Summary Long-term stability of horizontal wellbore completions with uncemented liners in weakly consolidated to unconsolidated sandstone formations (e.g., the Gulf of Mexico and Nigeria) remains an area of concern. In this paper we present the resul.horizontal sand production,Imaging of Sand Production in a Horizontal Sand Pack by X-Ray .A laboratory experiment was designed to model sand production into a perforation in a vertical well drilled into the heavy oil formation. In this experiment, heavy oil (21,500 cP) flowed through a horizontal sand pack and into an orifice simulating a perforation. The flowing dead oil induced the co-production of sand from the.

Sand Production Analysis for Depleted Reservoir - CiteSeerX

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 affected, and the stress state will be changed, so that to cause sand production. Based on Hooke's law, the theoretical formula of two horizontal stress.

Comprehensive Transient Modeling of Sand Production in .

Summary. Installing sand control in long horizontal wells is difficult and particularly challenging in offshore fields. It is, therefore, imperative to make decisions with regard to the most optimum completion type objectively and based on reliable assessment of the sanding potential and its severity over the life of the well for the.

New gravel-pack technique reduces sand production in Niger Delta .

In the Niger Delta, off Nigeria, field experience based on a learning curve derived from gravel packing in conventional wells proved effective for improving gravel packs in monobore and horizontal wells. Operators also reduced the need for remedial sand-control repairs by extensively applying coiled tubing in gravel.

The physical and numerical modeling of sand production and gravel .

This research studies the effect of gravel pack size on sand production by designing and manufacturing a machine and a numerical model to simulate sand and gravel pack. This machine and the numerical.

Sand Screen Design and Optimization for Horizontal Wells Using .

Feb 10, 2018 . Current screen design approach fits one screen opening size for the entire length of the well, which leads to a conservative screen opening to avoid sand production along the well. This study introduces a new approach to design the screen opening, considering different opening sizes along the horizontal.

Sand Control - Schlumberger

which cannot be easily completed other- wise (see “Screening Horizontal Wells,” page 45). Slots are typically sized to cause bridging of the largest 10% of the formation particles, filling the annulus between the screen and casing, or open hole, with formation sand creating a filter for remaining particles. However, production.

We then run field case studies and validate the sanding onset .. sanding phenomenon in vertical and horizontal wells; (2) analytical 2D plane strain.

Sand casting - Wikipedia

Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. Over 70% of all metal castings are.

Horizontal oriented perforating stabilizes formation - Drilling Contractor

in long horizontal sections have helped to optimize perforation efficiency and production. While these new techniques are applicable to any horizontal or high- ly deviated well, they are especially important where orientation of charges is critical to maintain wellbore stability and control sand production. Perforating with.

The Importance of Sand Characterization for Efficient Well .

To some extent this is because the production problems inherent with horizontal wells are only now emerging and starting to be studied and understood after a few years of well production. In addition, engineers are learning that carrying out the type of remediation work common to vertical wells is extremely difficult and.
