DPD Overview and Application Drivers
- Introduction and expectations
- DPD overview
- DPD application drivers
Participants will be given an overview of the large variety of DPD technologies, the IADC risk classification of these technologies in order to put them into some kind of perspective, and a brief history lesson on how these technologies have emerged, especially in the last decade. To understand why these technologies have developed it is important to understand the application drivers for the implementation of these technologies; this can range from a simple desire to increase ROP to the more complex and challenging reservoir characterization in real time while drilling.
DPD Techniques and Fluids
- DPD Techniques
- DPD Fluid selection
- DPD Gas selection
- Specialty single phase fluids
- Two phase flow
The various DPD techniques will be examined one by one, going over the methodology, current status, and advantages & disadvantages of each technology and where they should be applied. DPD Pressure Drilling reduces the necessity for heavier fluids and opens up opportunities to use lighter fluids and some novel fluid options will be discussed. For Underbalanced Drilling, it is often necessary to use injected gas to lighten the fluid, therefore the various gases that can be used and the ways of injecting them into the well bore will be covered along with two-phase flow physics and modelling.
- Rotating Control Devices
- MPD equipment
- UBD equipment
Day three will focus on the equipment used in DPD operations. Starting with the Rotating Control Device, which is at the heart of holding pressure in the wellbore while drilling, then moving onto the various pieces of surface equipment that are used in both managed pressure and underbalanced drilling. Equipment covered will include chokes, separators, flow meters, nitrogen generation, flare lines and ancillary equipment. Participants will gain familiarity with the equipment, learn how the equipment works and the selection criteria for equipment in different applications. Various equipment layouts for different applications will also be covered including onshore, offshore and deep water.
DPD Design and Control
- MPD Design & Control
- UBD Design & Control
- PMCD Design & Control
- DPD Tripping & Completion
The fourth day will be all about the design and control of DPD operations. Of the upmost importance is well control and participants will learn about the differences between the primary barriers in conventional drilling versus DPD operations. The design of various DPD operations (MPD, UBD & PMCD) will be discussed, with the concept of the ‘Anchor Point’ in MPD operations covered in detail. Drilling with DPD techniques is often considered the ‘easy’ part, while tripping, running casing and cementing require the most thought and attention. The attendees will learn about the various methods to trip in and out of the well while staying in the drilling pressure window, as well as how to successfully cement and/or complete the well following a DPD operation.
DPD Project Implementation
- DPD candidate selection
- DPD project management and HSE
- Final Exam
The last day will build on the knowledge gained from the previous days and will look at how to select the appropriate candidates for DPD operations. Contra-indicators for using DPD techniques will be discussed. The overall implementation and management of a typical DPD project will be examined with the emphasis on ensuring that the project is delivered safely through training and appropriate use of barriers.
This course is designed for drilling professionals embarking on a Dynamic Pressure Drilling assessment.
Participants should have a fundamental understanding of basic drilling technology.
Yogyakarta is renowned as a center of classical Javanese fine art and culture such as batik, ballet, drama, music, poetry, and puppet shows. It is also famous as a center for Indonesian higher education.
Being one of the oldest cities in Indonesia, Yogyakarta has many heritage buildings and monuments. The number one must-see attraction is Sri Sultan Hamengkubuwono's palace, better known as Kraton Ngayogyakarta. Other heritage buildings from colonial era are: BNI '46 building, Kantor Pos Besar (Central Post Office) building, and Bank Indonesia building, all of them are located near Sultan's palace.
The massive Buddhist temple of Borobudur, the largest Buddhist monument in the world, is 40 minutes away by car and one of the main drawcards for visitors to Yogyakarta. The Hindu temples of Prambanan, just 20 minutes away, are a close second. The smaller temples of Kalasan and others are on the way to Prambanan. Ratu Boko palace, only 2 km north of Prambanan. An ancient royal palace complex, similar in architectural layout with other Kratons or palaces in Java. Magnificently located on top of a hill, Ratu Boko has been recently restored.
Parangtritis on the south coast is one of the better known beaches. Local folklore suggests that this beach is the palace of the legendary Nyai Loro Kidul or 'Queen of the South'. It is common knowledge among locals not to wear anything green in color, or the Queen will entice the wearer into the ocean to drown.
Yogyakarta's Adisucipto International Airport (JOG), 8 km east of town, is a small but busy mostly-domestic hub. There are near-hourly connections on Garuda to Jakarta (50 minutes) and Denpasar, while other domestic airlines service major cities in Java, Sumatra, Kalimantan and Sulawesi. For international services, AirAsia connects Yogyakarta to both Kuala Lumpur and Singapore while Malaysia Airlines flies between Yogyakarta and Kuala Lumpur.
