Abstract: Transport through porous medium occurs in numerous processes of environmental, chemical, petroleum and civil engineering. A lot of investigations have been done in order to understand the mechanisms of the transport of particulate suspension flow through porous medium. Transport of particulate suspensions and colloids in porous media is accompanied by particle capture and consequent permeability decline. In general, deep bed filtration studies have been conducted to analyse the mechanism involved in the processes of capturing and retaining particles occurs throughout the entire depth of the filter and not just on the filter surface. In this work, the steady-state transport equation is presented and the solution to the complete advective-dispersion equation for particulate suspension flow has been derived for the case of a constant filter coefficient. This model includes transport parameters which are particle advective velocity and particle longitudinal dispersion coefficient. This theoretical investigation of the transport of particles flowing in porous media is limited to flows with low Reynolds number (linear and laminar flow) and high Peclet number.Abstract: Transport through porous medium occurs in numerous processes of environmental, chemical, petroleum and civil engineering.

Abstract: Although Habiganj Gas Field is one of the best gas field with good reservoir characteristics but it is least analyzed. This paper presents the critical view on four wells (HBJ -7, HBJ-8, HBJ-9, and HBJ-10) of upper gas sand using wire line log data for further development. It is found from the analyses data that a thick zone (~40 m, depth between 1410 to 1450 m) of Bokabil Formation in well no. 8 HBJ-8 shows greater porosity (>43%) and permeability (5-16 D) which may be the indicators of a big fracture zone within the reservoir that yet to be noticed. The similar phenomenon also observed in HBJ-9 with laser thickness. The consistency in porosity and permeability of different wells shows that the reservoir of Habiganj Gas Field is well-sorted. However the stratigraphical model shows that the structure of Habiganj Gas field is almost symmetrical and trending SSE, which supports the structure of Surma Basin. The multi-log 3-D model shows both lithology and stratigraphy, which also resemblance with the lithology and stratigraphy of the Surma Basin.Abstract: Although Habiganj Gas Field is one of the best gas field with good reservoir characteristics but it is least analyzed.
