Flood disaster is a natural disaster that ranks the third cause of economic loss worldwide. As a tropical country that has a rainy season, every year some parts of Indonesia are prone for being affected by floods. The causative factors include high rainfall and poor surface water management, making rainwater directly converted into surface water (run-off). Efforts to reduce run-off water include making biopores infiltration wells from paralon pipe material with a diameter of 10 centimeters, but because of the small volume, the biopores cannot functioned properly, so it is necessary to build infiltration wells with a larger capacity. The purpose of this research is to make a model of infiltration wells that have a larger volume than stainless steel.
This study used a pre-experimental design and is a development research of biopores infiltration wells. The stages in this research include design validation and absorption function testing.
The results of the study were the design of a box-shaped absorption container with a height of 120 cm. 100 cm wide and 100 cm long, made of 304 stainless steel, with an inlet and outlet holes for rainwater, a bottom absorption area, and has a lid that is easy to open for cleaning. In the function test, it was obtained the ability to accommodate rainwater of 1.2 cubic meters and the ability to absorb water of 0.9 liters per second on the soil of the test location, so that this infiltration box is estimated to be able to accommodate rainfall of 120 mm a day.
The conclusion is that this rainwater absorption container is able to accommodate rainwater while absorbing water so that it can be an alternative technology for preventing flood.

/in /by

The well logging method is one of the methods used in petrophysical analysis to assess the formations used in obtaining information and shadows related to a reservoir. In addition, in an effort to determine success in the oil and gas field, this method is also included for calculating petrophysical values such as permeability, water saturation, and porosity. Then this value will be used in finding the initial oil reserves (OOIP) and initial gas reserves (GIIP) in the MA field. This will be very helpful in developing further oil and gas fields because materials are available as a basis for reference. This study analyzes the MA field precisely at the MA-06 Well by utilizing the qualitative and quantitative petrophysical analysis method by only referring to log data because there is no availability of core data. To find out the depth of the prospect zone and what fluid is in the formation, the authors analyze it in a qualitative way, namely by determining the permeable zone, then looking at the resistivity value, then determining the type of fluid on track 3. While in obtaining petrophysical values such as shale volume, porosity, water saturation and rock permeability the authors chose to use quantitative methods to analyze them. So that the results of the analysis carried out, it was found that the MAXX well has a net sand thickness of 36 feet and a net pay of 36 feet with an average value of shale volume, porosity, water saturation and permeability in that zone respectively 34.8%. , 18.03%, 35.3%, and 38.31 mD.
