Di era Internet of Things (IoT). Siapapun dapat mengakses data dimanapun dan kapanpun. Semua data yang tersimpan dapat diakses dengan menggunakan perangkat seperti smartphone, laptop, dan komputer. Salah satu dari teknologi Internet of Things adalah smart city untuk memonitoring lingkungan. Untuk dapat mengetahui kondisi dan kualitas suatu lingkungan, seseorang tidak perlu lagi menunggu pengumuman informasi atau datang ke instansi terkait di pemerintahan. Pemanfaatan IoT pada monitoring lingkungan dapat di terapkan pada bidang peternakan. Hal ini dapat membantu seseorang dalam mengetahui kualitas dari kondisi lingkungan yang akan dimanfaatkan untuk peternakan. Dalam hal ini adalah bagaimana mengetahui peternakan yang cocok untuk diterapkan dilingkungan yang dia tuju untuk membangun peternakan sapi atau peternakan ayam. Menggunakan perangkat wireless sensor networks (WSN) untuk melakukan pengambilan nilai dari kondisi lingkungan tersebut dapat membantu mengetahui kondisi dan kualitas lingkungan. IoT membantu seseorang untuk membuka usaha dibidang peternakan yang cocok untuk wilayah tersebut tanpa harus melakukan banyak survey yang menelan banyak biaya. Hanya dengan menggunakan teknologi IoT siapapun dapat mendapatkan data kualitas lingkungan yang cocok untuk membuka sebuah peternakan dengan kondisi lingkungan yang sudah diketahui sebelumnya.

Laboratory Research on Fluid Flowing Through Porous Media - Surfactants in an Oil-Water-Sand System
Authors: James Keith E. 
Published: February 2020

Fall Meeting of the Los Angeles Basin Section, 16–17 October, Los Angeles, California

Abstract
Considerable attention has been given by the oil industry to interpreting and predicting fluid activity in porous material, particularly as based on laboratory tests. Though much of the previously published information is based on actual formation sampling or simulation, the methods described here will not duplicate formation conditions. We plan rather to understand better the principles of fluid-solid phenomena, primarily at the pores space level. The ultimate goal of most applied research is generally a reduction of physical phenomena to statistical formulation. With the belief that such will eventually come to pass it is nevertheless necessary to confront immediately and directly certain theoretical concepts. Unfortunately, the classical definitions of many of these parameters—wettability, adsorption, interfacial tension, capillarity, and the shear and stress acting on each—fail to provide the essential working direction for expedient and empirical application. It is therefore necessary to delve deeper into the constants, the correction factors, and similar equalizing devices with the intent of elucidating additional integral components.
Photomicrographic and cinemicrographic data have been collected showing an essentially two-phase liquid interacting in a sand matrix. This system is acted upon by selected surfactants which alter such usual oil-water relationships as interfacial tension, emulsification, and film-forming phenomena. These and other factors in turn affect the dynamics of the respective liquids moving through pore spaces and flow channels. The liquids interact with the matrix wall partially governed by such loosely-defined parameters as wettability capillarity and adsorption. The present study is directed to gain insight into the manner in which these surface active agents restrict or enhance the flow of fluids through unconsolidated and consolidated sand.

Introduction
It has been demonstrated repeatedly in publications and conferences on fluid flow that more information in the form of raw data, followed by critical appraisal, is needed to fill the gap between a purely theoretical analysis and expedient application.

Quick Methods for (1) Determining Saturation at Breakthrough (2)Approximating Relative Permeability and (3) Evaluating Preferential Wettability

Abstract
In this study generalizations have been devised with respect to oil-reservoir-analysis data processed by the electronic computer, from which useful relationships were obtained. These relationships are presented in a graph, the ordinate of which is the product of the ratio of the upper extremities of the permeability curves and the ratio of the viscosities. The abscissa is the fractional saturation at breakthrough. The parameters are related to the values of the permeability curves at a saturation midpoint between the irreducible water and oil saturations.
Three important determinations can be made by using the graphical data:with relative permeability relationships obtained in the laboratory. saturation at breakthrough can be approximated by using the upper extremities and the midpoints of the relative permeability curves;the effect of preferential wettability can be approximated; andif the permeability data are not available a method is proposed by which relative permeabilities can be quickly approximated.
By using high rates of flow in oilfield cores to minimize the end effects, upper extremities of the permeability curves and saturation at breakthrough can be measured. By means of these experimental data and the graph the midpoints can be determined; then, the approximate relative permeability curves can be drawn.

Summary and Introduction
As part of a study of application of the Buckley-Leverett method to an analysis of oil-reservoir performance covering a wide range of relative permeabilities and oil saturations, a method has been devised for quickly determining average water saturation at breakthrough from relative permeability data. The base for the relative permeability used in the report is either permeability to air or effective permeability to oil at the irreducible water saturation. The permeability to air also was used because of the large backlog of air permeabilities available to reservoir engineers.
Basic data were calculated by an electronic computer and are presented in a single graph from which the point of breakthrough may be obtained.
High Volume Lift with Hydraulic Long Stroke Pumping Units
Authors: Zuvanich P.L. 
Published: February 2020

Fifth Annual Joint Meeting of the Rocky Mountain Petroleum Sections of AIME, 2–3 April, Casper, Wyoming

Introduction
Hydraulic long stroke pumping units are not new, having been on the market for more than twenty years. However, most applications have been in California and in the mid-continent area. There are still only a very few in use in the Rocky Mountain Region.
Hydraulic long stroke units are well suited for high volume lift in deep wells, being capable of lifting nearly 1,000 B/D from 8,000 ft. There are many places in the Rockies where they might profitably be used. It is the purpose of this paper to present the results of the application of two hydraulic long stroke pumping units to high volume lift in the Meadow Creek Tensleep reservoir, Johnson County, Wyo.
There are 13 wells in the reservoir completed in the Tensleep sand at an average depth of 9,000 ft. The produced crude is black, asphaltic, 31 API, and has a solution gas-oil ratio of only 16 cu ft/bbl. The reservoir has an active water drive with all wells producing some water. The discovery well was completed in March, 1952, and development was completed in June, 1955. Although initially capable of flowing, all wells were being pumped by Feb., 1955.
During 1956, fluid withdrawals were increased by rung larger pumps in six wells. Reservoir performance indicated that even greater withdrawals were possible. In order to increase withdrawals, it was necessary to change surface equipment. A hydraulic long stroke pumping unit was installed to pump Well 98in April, 1957. In May, 1958, another was installed at Well 95.

Hydraulic Long Stroke Pumping Unit
A detailed description of the operation of the hydraulic pumping unit is beyond the scope of this paper, but a brief discussion is pertinent.
On the upstroke, air pressure in the reservoir discharges the hydraulic oil to the pump where it is boosted to the underside of the piston. The piston moves up the cylinder with its load of rods and well fluid. On the down stroke the weight of the rods and fluid force the hydraulic oil back to the pump where it is boosted and discharged into the reservoir against the counterbalancing air pressure. A reversing valve makes the appropriate changes in the intake and discharge of the pump at the top of the stroke and again at the bottom of the stroke.
