The influence of reservoir rock properties on sand production in wells is considered. It was concluded that the rock should be considered rather not from the point of view of its strength, but from the point of view of the type of cementitious substance and its distribution. When predicting sand production, it is necessary to take into account the internal stresses of the rocks, as well as the change in these stresses during drilling, perforation and operation of the formation due to the violation of their initial state. Within the framework of this work, an analysis of the main causes of sand production during the operation of gas wells and the negative consequences of sand production for gas production equipment is presented. It has been established that water breakthrough, formation depletion, pressure drop at the bottom of the wells due to their frequent shutdown are the main prerequisites for the removal of sand from the bottomhole formation zone. Sand production is associated with such negative consequences as plugging in wells, erosion of underground and surface equipment, collapse of the top of the bottomhole formation zone and production strings. The main technologies for the prevention and elimination of accidents associated with the removal of mechanical particles from the reservoir are considered. Based on the research results, an algorithm was proposed for selecting technological modes of well operation in conditions of water and sand. The parameters for choosing the optimal operating mode of a gas well are substantiated, in which sand is not extracted with the subsequent disabling of downhole and wellhead equipment, the integrity of the bottomhole zone is not violated, and the well is not selfcontained. The results obtained can be applied to improve the efficiency of gas wells operation and predict their trouble-free operation.

“…Other indicators that impact the sandcontrol design have been suggested by George King et al in SPE 39437. 1 The King et al approach suggests evaluating a sorting coefficient and percentage of fines (sub 44 micron particles) in the formation sample to assist in selecting the sandface completion. Sorting coefficient (defined as D10/D95) gives a broader evaluation of the sand-size distribution, and in the F13-6, core was in the range of 2.5 to 130, further confirming that the Shallow Clastics formation is composed of highly nonuniform sand-grain sizes.…”

The Shallow Clastics Field, which is operated by Sarawak Shell, primarily targets two shallow gas-bearing reservoirs, H1 and H2, at approximately 2,650 ft true vertical depth (TVD). An appraisal/early-producer well with a deviated wellbore was drilled through the H1, H2 targets, and a completion design consisting of a cased and perforated commingled completion inside 9-5/8-in. casing was implemented. The sand-face completion design consisted of a large-OD expandable sand screen with 150 micron weave that opened across the 2 zones. Upon completion, the reservoirs were cleaned up through a temporary well clean-up and test facility to test productivity and evaluate integrity of the downhole sand-exclusion installation. Fines production, possibly due to a failure of the expandable screens, commenced almost immediately upon well bean-up and steadily increased to the extent that the well was deemed unproducible to the facilities.Because of the failure of the first well, a re-evaluation of the sand exclusion method that included more extensive core analysis and the completion types that would be suitable for development of the H1/H2 reservoirs was carried out. From this review, the operator and a service/ engineering company were able to develop an innovative sand-exclusion method that combined several new technologies.To date, four wells have been completed with the new well configuration and sand-exclusion method chosen to address completion needs. These have been tested, and to date, have proven to be operating satisfactorily. This paper will review the evaluation that led to the sandface completion design, the field implementation of the design, and the key installation success factors that were required. Results and a summary of best practices from the initial installations will also be summarized.

“…But the gravel packing is used in concert with other screen in oil field which is fit for the formation of high fine particles content. Such as, Tiffin (Tiffin et al 1998(Tiffin et al , 2003 introduced two new parameters in sand control with the sand particle size distribution: sorting characteristics (SC = d10/d95) and fine particles (the quality percentage of \45 lm particles), and the gravel packing completion was used in the formation of high fine particles content. Mohamad et al (2008) published an article in the JPT which showed fine particles (\45 lm) content with 35 %.…”

The fine particles have significant influence for sand control mode selection. According to investigation and analysis, we learn that the gravel packing has been used widespread in sand control when the contents of fine particles are high. Based on designing the pre-packed screen, different fine particles sand control research is completed combining with test method. (1) We find that the sequence of fine particles flowing into the well has an enormous impact on the screen jam rate, and the smaller the fine particle diameter, the more obvious the screen plugging. The jam rate for the pure clay is five times with pure finesilty sand, and four times with mixture of the fine-silty sand and the clay. When the experimental achieve octet stability, the Fluid Productivity Index Per-Meter (FPIPM) of the pure clay is pretty much equivalent with the mixture of the finesilty sand and the clay. It is 70 % of the pure fine-silty sand FPIPM but has limited influence to effectiveness of the blockage. (2) Sand control selection in the offshore oilfield suggests the gravel packing will be applied when the fine particles content is over 5 %. Compared to this select range, it is conservative and experiments show that the fine particles content achieves 100 %, the pre-packed screen also can cope with sand control effectively. When comparing with experimental result about the gravel packing sand control under the same condition, the both FPIPM in steady is same. So, it is more suitable to be widely used combined with the production cost.
