Abstract

The evaluation of hydraulics carried out in a trajectory namely 17 ½ inches provides an overview of the hydraulic problems that occur with less-than-optimal pressure in the bit because it is less than the minimum percentage value that should be. which is less than 50%. it is affected by factors such as flow rate. mud weight. the rheology of the mud used and pressure loss both in the surface and sub-surface such as bit. pipe and annulus. So, optimization with the BHHP (Bit Hydraulic Horse Power) method becomes the next step to be taken in order for the drilling operation can perform better. It has been found from the optimization results that the CTR (Cutting Transport Ratio) method is a cutting analysis method that demonstrates the correct performance of the cutting transport process if the minimum percentage of 50% or higher is met. In addition, this method also takes the angle of inclination of a directional well Y-1 into one of the considerations. On the first trajectory. 17 ½ inch hole (1338.58 – 3166.01 ft) the pressure in the bit increased from around 22.83% to 31.14% at the initial condition to 56.20% until 56.59% with cutting transport results after being optimized up to 99%. The use of the BHHP (Bit Hydraulic Horse Power) method to optimize drilling hydraulics in the directional well is said to be successful because it produces an optimization value that is greater than the minimum standard which is 50%. Furthermore, the CTR (Cutting Transport Ratio) method to analyze the transport of cuttings to the surface has been running well showing the results that the cuttings have been successfully transported to the surface. Therefore, this method can be said to be successful with the acquisition of a value percentage above 50%.

Abstract

Zeolite as a catalyst can increase its activity by carrying out physical and chemical activation processes. Physical activation can be activated by reducing the size of the zeolite through grinding and sieving methods, from the physical activation process it can increase the surface area of the zeolite. In this study, zeolite was chemically activated by acid activation method by immersing natural zeolite with HCl and HF. The oxide compound in the activated zeolite was characterized using XRF. The activated zeolite was used to reduce the free fatty acid levels with variations in the addition of 7 to 10 grams of zeolite. The content of free fatty acids is then compared with the quality requirements of cooking oil according to SNI 01-3741-2013. The results of the research conducted showed that there were differences in the content of oxide compounds in zeolite before and before activation with differences in SiO2 content, namely 69.4% before activation and an increase of 82.1% after activation. The results of the state test including physical properties, odor, and taste tests of used cooking oil that have been purified indicate that used cooking oil that has been purified meets the quality requirements of cooking oil based on SNI 01-3741-2013. Used cooking oil that has been purified has a normal taste, does not smell. rancid and yellow. The content of free fatty acids meets the requirements of SNI 01-3741-2013 for all variations of the addition of zeolite with the highest decreasing value obtained at the addition of 10 g of zeolite with a free fatty acid content value of 0.22%.

Abstract

There has been intensive investigation on the understanding of the liquid loading phenomenon lately via experiment and transient approach. This is driven due to the limitation of the traditional approach using steady state Turner correlation to be used over a wide range of actual conditions (i.e such as under various tubing diameters, fluid condition (CGR/WGR), and horizontal or deviated trajectory of the well) which can lead to underpredict critical gas rate and mitigation action which directly impact the production and economics limit of the field. By nature, the liquid loading phenomena classified as transient or dynamic phenomena and hence couldn’t be able to be explained under the steady state approach. The application of dynamic well modeling itself has been applied worldwide recently. Therefore, utilizing this new approach for estimating the critical gas rate for horizontal well bring benefit by reducing the uncertainty of the outcome and providing more accurate prediction compare to the traditional approach. The selection of the de-liquification method which uses the bullheading for the horizontal gas well in X field provides the highest production optimization and the most economical approach to the field as there is no additional opex cost required.

Abstract

One of the efforts that can be done to evaluate the performance of water injection in a field is by monitoring the injector wells. Observations can be made by looking at the flow rate and injection pressure at each injector well. The response given by each injection well will be able to represent the injection performance on a field scale. The EX structure is a structure that has been produced for more than 40 years. In addition, water injection has also been applied for approximately 16 years. There are four injection wells operating in this EX structure with an average injection flow rate of 3000-8000 bwipd per well. Evaluation of injection well performance is carried out by conducting a Hall Plot on each injection well from the start of the injection process to the last data obtained. Based on the evaluation results, it was found that there was plugging in the EA-IIS and EJ-IVS injection wells. Stimulation activity is needed in both wells to restore the well injection capability. Meanwhile, for the EA-IS and EB-IIL injection wells, there are no significant problems in those wells so they can still function properly as injection wells.

Abstract

This work investigates the impact of elevation on terrain-induced slugging in a riser system. Fluid compositions were modeled with multiflash and exported to OLGA in a readable PVT Table File. Pipeline materials and properties with geometry of different elevation were modeled in OLGA to develop a flowline model. Two geometries (1 and 2) of different elevations were defined to establish their effect on accumulated liquid volume flow, surge liquid volume, slug length, number of slugs and slug density. The result shows that Geometry 1 with a total elevation(height)of 450 ft has a total liquid volume flow of 10.1058 ft3/s and Geometry 2 with a total elevation(height) of 300 ft has a total liquid volume flow of 0.197822 ft3/s for the same time of 2473.99 seconds. Also, Geometry 1 has a surge liquid volume of 543.4608484 ft3 at a drain rate of 0.20843960 ft3/s and Geometry 2 with a surge liquid volume of 210.7395 ft3 at a drain rate of 0.23892 ft3/s. There was no slug length and number of slugs in pipe of Geometry 1 while Geometry 2 has a slug length of 531.78 ft indicating severe slug in Geometry 2 system of different elevation. The slug density of Geometry 2 system was twice that of Geometry 1. Change in the elevation for the geometries has shown a significant effect on terrain–induced slugging in the pipe-riser system.
