Materials Calculator. Whether excavating a trench or a hole for a tank or foundation, or stockpiling materials such as gravel or soil, there is often a need to make a field estimation of volume and weight. To fulfill this need, HTG developed a materials calculator using common measurements. The calculator conservatively assumes a relatively ...

The injection pump pressure was 700 psi when the gravel was first injected and was reduced to 500 psi when the gravel reached the heel of the horizontal well (i.e., the packing tool). The specific density of the gravel and sand carrier mixture was calculated to be 1.37sg, and the bulk density of the gravel was 1.26 g/cm³.

Effects of (a) gravel volume concentration and (b) viscosity of sand-carrier on the gravel packing extending limits at the virtual horizontal well located at the site SH2. In Fig. 10 (a), the seawater is used as the sand-carrier, the density of seawater is 1.025 g/cm 3 and the viscosity of seawater is 1 mPa s.
Horizontal well is preferred for marine natural gas hydrate (NGH) production, while a robust completion method is required to control the associated sand production. …
1 INTRODUCTION. Although, openhole gravel packing is now viewed as a means of enhancing the reliability, efficiency, and longevity of horizontal sand control completions, 1-6 there are still considerable risks in horizontal well gravel packing, especially in extreme cases such as long horizontal well and unconsolidated sandstone reservoir. 7-9 It is …

Expert Answer. Sol:- The angle of response is the angle formed by the cone's surface with the horizontal. Solve the problem. When granular material such as sand or gravel is poured onto a horizontal surface it forms a right circular cone. The angle that the surface of the cone makes with the horizontal is called the angle of repose.
