Drilling

Onshore unconventional drilling is commonly used in the extraction of oil and natural gas today. There are an increasing number of multi-well pad type drilling programs in most of the active plays. Different drilling technics are used to decrease drilling time, lower environmental impact and to improve initial and estimated ultimate recovery.

Wellhead & Separation thumbnail

Wellhead & Separation

The wellhead provides the structural and pressure-containing interface for the drilling and production equipment. The surface pressure control is provided by a christmas tree, which is installed on top of the wellhead. Isolation valves and choke equipment physically control the flow of well fluids when the well goes into production. Various automation packages are added to locally or remotely monitor, control and optimize production from each well or multi-well pad. Oilfield separators employ a pressure vessel to separate well fluids produced from oil and gas wells into gaseous and liquid components which are then transferred to pipelines or localized storage depending on the areas infrastructure.

Processing & Fractionation thumbnail

Processing & Fractionation

Natural-gas processing is designed to control the dew point of the natural gas stream and to separate the natural gas liquids for sale and distribution. Oil and condensate removal, water removal, separation of natural gas liquids and sulfur & carbon dioxide removal are processes used to separate impurities in the feed coming from upstream reservoirs. The fractionation process takes the liquid streams from the gas processing plant, which may consist of methane, propane, butane and pentane and treats them in separate fractionation columns which may then go to an impurity treatment plant before being sold as separate components.

Yokogawa total solutions include not only the well site, but also the injection, pipeline, compressor station, and the process plant facility. Our experience for these applications can be integrated to optimize the overall operation capability and maintainability.

Overview:

Measuring energy consumption is an important factor in the quest to improve energy efficiency. Efficient and accurate metering is paramount to determining excess use, along with an accurate picture of where the steam is being used. The more accurate and reliable measurements that are made, the more informed decisions can be taken that affect costs and product quality. Traditionally the most common method of steam metering is the orifice plate and differential pressure transmitter technique. General areas of concern with this type of measurement are the orifice plate's susceptibility to wear introducing immediate inaccuracies, the relatively high permanent pressure losses introduced into the system by the orifice place and the small measuring range, typically 3:1.

Yokogawa's digitalYEWFLO Reduced Bore Type Vortex Flow meter features a cast stainless steel body and a concentric reducer and expander that enable stable flow rate measurements in low-flow conditions. This expands the range of measurements that can be performed, from the higher flow rates down to the lower end of the flow span, which is normally difficult for Vortex Flow meters, and ensures stable and accurate flow rate output.
