Standardizing Well Pad Designs Leads To Significant Savings
Peyto Exploration and Development in Alberta, Canada has experienced significant savings and natural gas production efficiencies by standardizing well pad designs. The company now has 20 identical well pads located in its Sundance fields about 175 miles west of Edmonton. Each well pad contains two to four wellheads. Horizontal drilling permits consolidating the four wellheads into a single pad.

Summary Of Carbon Dioxide Enhanced Oil Recover (CO₂EOR) Injection Well Technology The purpose of this report is to identify the technologies and operating practices that have been developed by the oil and gas industry for injecting carbon dioxide (CO₂) for enhanced oil recovery (EOR).
Multilateral Well: Quantitative Inflow Interpretation Of RESMAN Intelligent Tracers In A Multilateral Well This application illustrates the power of RESMAN Intelligent Tracers to provide significant insight into the inflow distribution along each lateral of a multilateral well.
Fearless Flow Back: Treating Completion Fluids And Acid Flow Backs An oil company completed a well and CETCO Oilfield Services was there to treat the flow back fluids. During the flow back, it was necessary for the oil company to continue normal drilling operations. Deck space on the structure was at a premium for the oil company, who simultaneously continued drilling while flow back fluids were being treated.
Artificial Lift Monitoring System Improved Performance Of Dynamic North Dakota Well Over a ten-year period, a major operator tried various methods to optimize production on a particularly gassy, dynamic well in North Dakota. The customer then asked Baker Hughes to install an ESP system with WellLink SPVision artificial lift monitoring solution to provide advanced surveillance for the well.
Completion System Designed To Monitor Frac Operation A well located in the Bakken shale had a vertical cased section of 10,000 ft (3048 m) and a 10,000 ft openhole horizontal section. The completion consisted of 10 stages; five of the stages were monitored using PT gauges. The operator wanted to monitor separate frac events in multiple zones and to continue monitoring the zones during production.
Optimizing Well Locations In The Niobrana The Niobrara shale play with its rugged terrain, environmental sensitivities, structurally complex geology and fractured shale reservoir exemplifies the unique operational and imaging challenges often found in unconventional reservoirs.
Precision Leak Detection In Complex Completion Delivers Substantial Operator Savings A failed pressure test following the installation of a new completion in a North Sea oil producer led to the discovery of a 2 l/min. leak.

First Quarter Oil And Natural Gas Well Completions Hold Steady
Estimated U.S. oil well completions remained relatively flat in the first quarter of 2014 compared to year-ago levels, according to API's 2014 Quarterly Well Completion Report, First Quarter.
API: Oil Well Completions Up In 2013, Natural Gas Completions Down
Oil well drilling rose in 2013 with total oil well completions up 5 percent from 2012, according to API's 2013 Quarterly Well Completion Report.

Well Completion
Well completion is a process that takes place after a oil or gas well has been verified to be commercially viable. Well completion involves casing, temperature and pressure evaluation and equipment installation to allow gas or oil drilling. Completion therefore has to wait for formation testing after a design well depth has been established. The specific activities involved in well completion include; drill stem tests (DST), production casting, production tubing installation, production flow commencement and installation of beam pumping units.
Drill stem tests have to be conducted to determine production formation potential. The DST experts use appropriate tools lowered into the bottom of the drilling hole to establish the formation potential. Adjustments are made to the tool to establish if the pressure is sufficient for production. This process should be left to the professional crew as hazards such as getting stuck by the test tool in floor testing. Exposure to h2s and other gases as well as blowouts are other hazards that only professional crews know how to deal with.
Production tubing installation is the other process involved in well completion. Small diameter tubing is more preferred to the larger ones in mining. Using couplings, individual tubing is joined to form a tubing string. The tubing that is to be used in mining is made using power tongs. With the advancement in technology, tubing can be made in the form of a continuous coil.
The final step in well completion is the initial production flow. Brine or water is injected into the well to remove the drilling fluid. This should be enough to initiate the flowing of the well. In the event that the well fails to flow under such circumstances, unloading or high pressure gas injection might be necessary. Caution should be taken since blowouts might occur if the well pressures happen to be charged.
