Problem identification

Well servicing operation performed on the hydrocarbon well has two objectives: finding out how the status of the well itself or the reservoir is evolving, and maintaining or adapting the well to keep the best possible operating conditions. Well servicing operations are done over the field’s lifetime. The operations that may have to be carried out on a well are numerous and can be broken down into measurements, maintenance, and workover.

Monitoring a well servicing operation is different with well drilling monitoring. A drilling operation performance can be measured by following the Time-Depth-Cost (TDC) curve. A plateau shown in the depth curve over the time indicates a non productive time (NPT). While a well drilling means a well construction, a well servicing is done in a constructed well. It means that TDC curve is not a suitable to measure well servicing performance. Continue reading

## W10_SSD_Selection of Solar Photovoltaic System Based on External Rate of Return (ERR)

1. Problem Definition

In this blog I am going to do find out the External Rate of Return for my PV installation, based on the data that I had used for my W4 Blog. With this Blog, I also would like to use this blog to claim for Problem Solving Work for Engineering Economic Chapter 5 Evaluating a Single Project.

The ERR calculation is based on the following formula:

(1-1)

Rk = excess of revenue over expenditure in period k;

Ek = excess of expenditure over revenue in period k;

N = project life

ϵ = external reinvestment rate per period

i’% = ERR

Based on equation 1-1, the following formula is developed:

(1-2)

## W10_ANG_Payback Period for Student Pick-up Service

Problem Statement

Following my previous blog posting, on this posting I would discuss about Payback Period of Student Pick-up Service Business. I would simulate the payback calculation to determine the decision of funding scheme based on payback period of investment. On this posting, I put three scenarios: 1st is fully using equity fund, 2nd is using mixed equity and debt which ten million rupiah of investment (21.74%) is using debt and 3rd is also mixed which forty million rupiah of investment (86.96%) is using debt.
