Tech Paper: Application of Lean Principles to Accelerate Project Development in the North Sea

Lean principles cut North Sea development completion by two years Oil and gas project development in the North Sea is known for large discoveries, requiring the need for highly complex, capital intensive infrastructure, which can take decades to complete. Recognizing that such discoveries were becoming less common, a faster and less capital intensive approach was needed to develop smaller fields. The idea was...

Tech Paper: Addressing Challenges for Successful P&A on a Deepwater Compliant Tower using Hydraulic Workover

Regulatory requirements and severe weather in the Gulf of Mexico make for challenging hydraulic workover conditions With the current government environmental directives in the Gulf of Mexico (GoM), operators are challenged to ensure that idle iron wells are correctly handled to meet regulatory requirements in the full abandonment of the wells and their platform structures. With this, there is a need to remove...

Case Study: Reliable Well Abandonment System Saves Time and Money During Storm Evacuation

Temporary well abandonment system stays intact in GOM for nine years, despite hurricanes CHALLENGE – It was hurricane season in the Gulf of Mexico, and a Halliburton client with a jack-up rig was faced with the challenge of oncoming Hurricane Katrina and a secondary hurricane, Hurricane Rita, while a well was being drilled. Evacuating personnel was the priority, but the risk of equipment damage left in...

Tech Paper: Managed Pressure Cementing Helps Reach TD in Ultra-HP/HT Well in Malaysia

Experiences and good practices from MPC successful execution This paper discusses the experiences and good practices established from successfully executing two managed pressure cementing (MPC) jobs within an ultra high-pressure/high-temperature (HP/HT) well in offshore Malaysia. The risks associated with cementing in sections with narrow margins between pore pressure and fracture gradient can often limit the length of each cased section, hence limiting the...

Tech Paper: Planning, Execution and Delivery of First Saudi Arabian Red Sea Deepwater Well: Project Management and Execution Case Study

The first deepwater well in the Saudi Arabian side of the Red Sea was going to be a rank wildcat well. Saudi Aramco Upstream leadership assembled a team of experienced, knowledgeable and dedicated professional staff across the Exploration Geology, Geophysics, Reservoir and Exploration Drilling organization to undertake the challenge of safe and successful well delivery. Contemporary frontier exploration projects utilize project development processes...

Case Study: Deepwater Offshore Mexico – Unconventional Reamer Solution

Enlarging a hole using an unconventional reamer solution saved a Halliburton client time and money while achieving excellent hole quality in deepwater offshore Mexico. CHALLENGE – Working in deepwater wells in Mexico provided one operator pressure drop and flow requirement constraints. These types of constraints require drilling a vertical hole with a rotary steerable system and enlarging the hole while doing it. They...

Case Study: Deepwater Gulf of Mexico – Huge Savings for Operators

Accomplishing in less than 8 hours what a competitor couldn’t do required a fast, accurate and safe solution for a Halliburton client in deepwater Gulf of Mexico. CHALLENGE – An operator working in the Gulf of Mexico was completing a deepwater well when they encountered stuck pipe that stalled operations, causing non-productive time (NPT) at a significant cost to the operations. They needed...

Making Better Real Time Decisions While Testing in Deepwater Exploratory Wells

Of critical importance, exploratory wells both represent the initial reservoir evaluation opportunity and help define subsequent development strategies. Hence the importance of obtaining high quality data with which to portray accurate static-dynamic reservoir characterization. This is the reason the drill stem test (DST) is one of the most important tests oil companies use to execute their exploratory wells. DST Operative Time and Cost...
