Well Services


Wellhead/Valve Leak Detection Qualification, Maintenance, and Replacement
Site experience has shown that 5-10% of valves leak, and 1-2% of valve cause 70% of total loss. When crude and gas recovery systems are in use, monitoring product valve leakage helps to identify and estimate the extent of the downgrading of valuable products to crude and gas due to valve leakage.


Our procedures for the detection of leaks through valves have been developed for use in Flow stations,Pipeline Valve Manifold, Gas Stations, Refineries, chemical plants, and Offshore Platforms. It enables estimation of through-valve crude and gas losses and leak rate.


CALAYA ENGINEERING SERVICES  LTD. Has a high-tech  operation that  offers different sizes for well head operations such as 0.092", 0.108", 0.125", 0.140", 0.150", and 0.160" in diameter, and is obtainable from the wire-drawing mills in one-piece standard lengths of18,000, 20,000, 25,000 and 30,000 foot lengths.

Hot Tapping / Stopple / Freezing Services

Hot Tapping:  The ability to safety tie-in to a pressurized system while under full operating conditions. Calaya engineering pipeline services uses the latest technology in coupon retention available.
Hot Taps can be performed on most any type of pipe, ranging from carbon steel to PVC. Taps are done on lines containing water, oil gases, fuels, steam and many other chemicals. Pressures up to 1440 psig at 1000 can be Hot Tapped safely with no interruption of service.


Piping Services
CALAYA has the experience and proven systems to help you cost-effectively decommission projects in ways that are both safe and environmentally responsible.
We have the capability to manage and perform the shutdown and commissioning of an entire field from reservoir through wellheads, flowline, and process facilities to export pipelines with all our own services, equipment and personnel. Pipelines can be cleaned and recertified for future use on other projects or completely decommissioned by flushing, cleaning and purging. Surface facilities can be cut and removed rapidly using our cold cutting, nitrogen foam inerting and hot cutting services as required.
