Excessive Fluid Loss Large amounts of make-up water is usually required and must be immediately available at all times when drilling in permeable sand and gravel. This is important because drilling fluid sometimes suddenly flows into permeable formations which are being drilled rather than circulating back up the borehole.
Natural gas from shale is being developed safely and responsibly today using technologies that have been proven over decades of use. Horizontal drilling became commercially viable in the s. Hydraulic fracturing has been used since the s in more than 2 million wells around world.
In the United States, 90 percent of oil and gas wells undergo hydraulic fracturing to enhance production flow rates. Chevron is pursuing advancements in technology and applying industry best practices throughout the full development life cycle to efficiently produce shale gas while protecting the environment.
Producing natural gas from shale is made possible by extended-reach horizontal drilling, to access the resource, and hydraulic fracturing where water under pressure is used to fracture the rock, releasing the trapped gas.
Once completed, these wells are expected to produce for 40 to 50 years. Elsewhere in the San Joaquin Valley, horizontal drilling is achieving similar results. A good example is the San Ardo Field, where horizontal drilling is enabling us to increase production by improving drainage from the heated portions of a much thicker reservoir.
Our drilling activities are designed to protect our workforce, the communities where we operate, and natural resources, including water, land and air. Our use of horizontal drilling enables us to gather natural gas from a large underground area with minimal surface interference, limiting our environmental footprint.
With a single pad, for example, we can produce from an area of about one square mile. And the wells for our shale operations are designed and drilled with control systems to protect groundwater throughout the life of the well. Similarly, our Subsea Mudlift Drilling SMD has the potential to make our safe and efficient deepwater drilling operations even safer.
SMD allows drillers to more quickly detect and appropriately react to downhole pressure changes, enhancing the safety and efficiency of deepwater drilling operations.
Advances in drilling technology will continue to take us into places that were previously inaccessible or uneconomic to drill. Horizontal drilling, combined with hydraulic fracturing, will continue to help us ramp up production of oil and natural gas from shale and tight resources ranging from Loma Campana in Argentina to the Permian Basin in West Texas and Southern New Mexico.
Gulf of Mexico and other areas. Subsea Mudlift Drilling will become a significant tool in enabling us to drill more efficiently and safely in these deep waters.Pacific Drilling: The Preferred Offshore Driller is a Harvard Business (HBR) Case Study on Leadership & Managing People, Fern Fort University provides HBR case study assignment help for just $ Our case solution is based on Case Study Method expertise & our global insights.
