Oil Displacement Efficiency

To study the distribution of remaining oil inside meandering channel sand body, the size of sand body architecture was calculated by the use of sedimentary facies, dense well, river parameters, cores, well logs and other data. The architecture of meandering channel that was crescent-shaped in plane and diagonal type in section was identifiable. On the base of study of architecture, the shielding of interlayer was classified into four types by the observation of oiliness interlayer. Framework of seepage flow was identified in meandering channel sand body. Several lateral accretion bodies between the completely choked interlayer constituted the flow unit. Combined with core analysis, the remaining oil in meandering channel sand body distributed in the upper and the middle of flow unit which did not connect with production well. The oil displacement efficiency in the flow unit was a positive rhythm in the flow unit. The oil displacement efficiency was a high-contrast positive rhythm in the lateral accretion body shielded by completely choked interlayer. That was a low-contrast positive rhythm in the lateral accretion body shielded by partly choked or restricted interlayer. All of these would provide guidance for developing the remaining oil.

Hysteresis Properties

Differential hysteresis processing is a new image processing technology that provides a tool for the display of image data information at any level of differential contrast resolution. This includes the maximum contrast resolution of the acquisition system which may be 1,000-times higher than that of the visual system (16 bit versus 6 bit). All microscopes acquire high precision contrasts at a level of <0.01-25% of the acquisition range in 16-bit - 8-bit data, but these contrasts are mostly invisible or only partially visible even in conventionally enhanced images. The processing principle of the differential hysteresis tool is based on hysteresis properties of intensity variations within an image.Differential hysteresis image processing moves a cursor of selected intensity range (hysteresis range) along lines through the image data reading each successive pixel intensity. The midpoint of the cursor provides the output data. If the intensity value of the following pixel falls outside of the actual cursor endpoint values, then the cursor follows the data either with its top or with its bottom, but if the pixels' intensity value falls within the cursor range, then the cursor maintains its intensity value.

The study aimed to determine the effect of rebon shirmp (mysis relicta) protein hydrolisate fortification to the sago noodles and to observe the characteristics of the sago noodles produced. The research was carried on in February – April 2019 in the  Laboratory of Fish Processing Technology, Integrated Laboratories, and the Fisheries and Marine Chemistry Laboratories at the Universitas Riau. The method used was the experimental method, designedas a non-factorial complete randomized design. The treatment conducted was addingof rebon shrimp protein hydrolysate at 4 level concentrations (0%, 5%, 10% dan 15%). The variables assessed were the quality of organoleptic (appearance, texture, odor, flavor) and the proximate composition. The results showed that the proteinhydrolysate of rebon shrimp at concentration of 15% was the best treatment and in accordance to the quality standards of dried noodles (SNI 01-2974-1996), indicated bythe highest organoleptic qualityof the dried noodles produced, including: the appearance that was brown, less attractive, whole, less neat; the texture that was dry and compact; the aroma that was quite fragrant, spesific rebon shrimp; and the taste that was quite tasty and shrimp flavored. The proximate composition ofthe best product was presented by the content of moisture, ash, fat, protein, and carbohydrate at 7.55%,1.02%, 0.17%, 16.76%, and 74.49%, respectively.Keywords: Hydrolysate protein, rebon shrimp, sago noodles
