Oilfield Services

Spa Group has been associated with the oil and gas industry for more than three decades now. We have many international collaborations for the Oil & Gas Industry, where we bring in new and innovative technologies to our customers.

Identifying prospective sweet spots before drilling

Oil exploration is an expensive, high-risk operation. Hitting the right spot for oil is a challenge in itself and if the hit is in the wrong place, the costs are enormous.
An industry rule of thumb is that cost of drilling a deepwater "dry hole" (a well with no oil) - is around $100 million, however sometimes it may be as much as $200 million.

To make the drilling process more effective and help finding prospective oil beds, Spa Group has understanding with Biodentify B.V, (a Netherlands based company) to provide a unique patented process that helps exploration companies improve their predictability by zeroing on “Sweet Spots” for exploration by using analysis of microbial DNA.

This analysis is different from other DNA analysis methods that use drill cuttings as samples to learn about unconventional drivers.
Biodentify uses soil samples taken from just one foot (1 ft.) below the surfaces. The technology is based on studying the microbial reactions to micro-seepages of gas molecules. Certain microbes, through oxidation, thrive on gas seepages while others die owing to toxic nature of these rising gases.
Either of the outcomes provides a usable signal that a “machine learning” model turns into a prediction map.
A single sample of soil contains as many as 3,00,000 microbial species, majority of them discovered newly. It is Biodentify’s understanding based on analysis, that only as little as 50 to 200 microbial species serve as a key indicator – negative or positive.
With the analysis of hundreds of samples, a map is produced to help explorers de-risk potential drilling locations. This method has a high prediction accuracy of 70 to 90%. The higher end of the range is possible to achieve if information is gleaned from an existing well in the targeted area.

Well Stimulation Services

Through our associates Emirates Western we provide specialized vessels to perform well stimulation on oil / gas wells to increase production by improving the flow of hydrocarbons from the reservoir into the well bore. These vessels provide safe, stable, advanced and efficient well stimulation services. Well stimulation can be accomplished through a variety of methods:

Acidizing:

The Oil & Gas industry has been using acid treatment (acidizing) to improve well productivity for more than 100 years. It is one of the most widely used and effective means available to oil and gas operators for improving productivity of wells. Well acidizing is achieved by pumping acid into the well to dissolve minerals and composites like limestone, dolomite and calcite cement between the sediment grains of the reservoir rocks. Acidizing is done on new wells to maximize their initial productivity and on aging wells to restore productivity and maximize the recovery of the energy resources. After an acid job is performed, the used acid and sediments removed from the reservoir are washed out of the well in a process called backflush.

Coiled Tubing Services:

Coiled tubing is commonly used to convey tools and circulate liquids and gases into and out of the wellbore without relieving the wellbore pressure. The coiled tubing is a continuous length of steel or composite tubing that is flexible enough to be wound on a large reel for transportation. The coiled tubing unit comprises of a reel with the coiled tubing, an injector, control console, power supply and well-control stack. The coiled tubing is injected into the existing production string, unwound from the reel and inserted into the well. Our coil tubing equipment’s provide cost effective and enhanced solutions in diverse range of tubing sizes, depth capabilities and shallow or deep wells.

Nitrogen Lifting Services:

Build-up or debris are not always the result of impairments to production. Heavy fluids accumulate in a well, restricting the flow of gas and oil. Using coiled tubing, nitrogen can be circulated through the wellbore to lift the heavier liquids out and improve production. Nitrogen gas lifting can also be used to remove spent acid following a stimulation treatment.

Hydraulic Fracturing

Hydraulic fracturing also known as “fracking,” is an oil and gas well development process that typically involves injecting water, sand, and chemicals under high pressure into a bedrock formation via the well. This process is intended to create new fractures in the rock as well as increase the size, extent, and connectivity of existing fractures. Hydraulic fracturing is a well-stimulation technique used commonly in low-permeability rocks like tight sandstone, shale, and some coal beds to increase oil and/or gas flow to a well from petroleum-bearing rock formations.
