According to market studies, all indications are that the importance of the shale gas market is not going to diminish in the foreseeable future. On the contrary, significant growth is projected in many quarters. For example, a 2011 report issued by ICF International on behalf of the INGAA Foundation predicted that total United States and Canada shale gas production will jump from 2010 levels of about 13 Bcf/d to 52 bcf/d by the year 2035.
There are over 2 million km of oil and gas production pipelines worldwide and ensuring the effective and efficient flow of products through these pipelines makes a huge difference in revenues generated.
A successful cleaning chemical formulation process for hydrocarbon transportation pipelines has been developed and applied in pipelines in the U.S. Case studies are included in this article.
The ability to use a single inline inspection (ILI) tool in one run to record multiple datasets is becoming increasingly important to pipeline owners and operators as they face a growing need to inspect their assets for a wide variety of defects.
Being subject to appropriate inspections, pipelines and piping/pipework offer an almost unlimited service life. Strength and actual service capabilities must be assessed at regular intervals. Especially for thin-walled pipes made of high-strength steel, it is of particular importance to conduct regular inspections and examinations to detect any flaws and defects before they actually start to cause problems. Here, ultrasonic and magnetic flux leakage (MFL) pigs have been established as proven and suitable tools for inspection applications.
The increased use of intelligent inspection pigs to determine the actual wall thickness of pipelines has given rise to the demand for a procedure to remedy wall thinning, laminations and sharp discontinuities, i.e. defects which normally make it necessary to restrict the maximum allowable operating pressure.
Full deployment and inspection of unpiggable pipelines has been achieved with Explorer II. Explorer II is an untethered, modular, remotely controllable, self-powered inspection robot for the visual and non-destructive inspection of 6- and 8-inch natural gas tranmission and distribution system pipelines.
