Cementing is an essential and critical process in the life of a well. In the construction phase cementing is required to cement casing in place by pumping cement into the annulus between the casing and the formation. Known as primary cementing this process provides several necessary benefits. Firstly it supports the casing. By sealing off formations it helps to achieve zone isolation between the different formation fluids (i.e. water, oil and gas) in the wellbore and it also forms a protective sheath around the casing against the effects of corrosive formation fluids. Remedial cementing is another type of cementing often required later on in the life of a well in order to repair casing leaks or prevent communication which has developed between zones.
Successful cementing requires proper job design and execution. Specific laboratory equipment is required to test cement slurry properties, cementing program software is used for job design whilst specialized heavy duty fit for purpose cement transport, pumping and mixing equipment are needed to carry out the job.
Cement slurries are formulated using various chemical additives to modify slurry properties in order to meet the extreme demands of downhole conditions and job design parameters. Casing hardware is utilized to ensure proper slurry placement. HAAS can offer the complete cementing package including qualified personnel, powerful reliable cementing equipment and proven products and materials.
HAAS can provide the stimulation skills to satisfy most oilfield stimulation needs. Whether its formation damage removal or creating new conductive flow paths, we can offer the solution.
Matrix Acidizing is today probably the most practiced type of oilfield stimulation treatment. This involves the placement of a formation reactive fluid (i.e. Hydrochloric acid in carbonate formations) into the wellbore matrix in order to improve hydrocarbon production from the reservoir.
This technique requires careful well candidate selection and fluid design to ensure optimum success and to avoid the potential to cause formation damage due to incompatibility. High pressure pumping equipment and special acid handling equipment is used to pump acid fluid into the well. Special care must be taken regarding the corrosive nature of the acid and its effect on downhole tubulares especially at elevated bottomhole temperatures. Fracturing is another well stimulation process where fluid is pumped into the wellbore at pressures high enough to fracture the formation. A prop-pant type material (such as coarse grained sand or similar) is often added to the carrying fluid and injected into the fracture in order to keep the fracture open. This provides a conductive path through which hydrocarbons can flow more freely into the wellbore hence significantly improving the well's potential to produce.
GPP can offer stimulation pumping equipment, stimulation chemicals and fluid designs to meet most customer requirements.
Coiled Tubing is a continuous length of pipe that can be manufactured to different lengths and sizes. The tubing is wound onto a large diameter reel from which it can then be run into an oil or gas well and subsequently pulled out after completing its operation. The tubing allows the select placement of various fluids such as acid, nitrogen, and many other fluid types into the well bore either to clean up the well and or improve production. Many assorted tools can also be run on the end of the tubing to perform a variety of tasks downhole.
In recent years coiled tubing has seen a dramatic growth within the oil industry. Technological advances has meant improved metallurgy, manufacturing techniques and quality control methods resulting in increased tubing reliability and the availability of larger pipe sizes. This combined with an increased number of downhole applications that can be run on coiled tubing has made it a serious rigless well intervention option due to its faster rig up times, quick running in and out of hole speed, thru tubing applications and the fact that it can be run on live wells.
GPP through its associates can provide API6A Gate Valves, Wellhead & Xmas Tree Equipment. These products meet international material standards conforming to API, NACE, ASTM and ASME requirements. A complete line of wellhead products is available for production and drilling use and encompasses both manual and automated heavy duty gate valves. Standard designs are available in each product line but new designs or variations can be quickly developed to meet customer specialized requirements. Refurbishment and recertification of wellhead equipment as per API repair standards is also available including also for BOP's and all types of valve repair.
Several sizes of solid block trees, having manually operated valves and actuator operated valves are available. The range manufactured covers single bore and dual bored. The advantage of going for solid block tree is reduced overall height and reduced potential leak paths. The associated tubing hanger sealing systems are designed accordingly to provide an overall integrated design installation. For services where higher corrosion levels may be experienced and/or H2S maybe expected integral tree blocks provide an economic solution by means of Inconel cladding of bored, sealing areas and valves cavities.

Need reliable, accurate downhole data? Need to obtain it efficiently and safely? Then allow HAAS to help you achieve your objectives by using their electric wireline services. We can give you the tools, the technology and the expertise to ensure you get the right results.
Electric wireline is used to convey a variety of electronically activated tools and sensors into producing and injection wells in order to acquire downhole data and information that can be used for reservoir information and management including well problem diagnosis. This is commonly referred to as production logging. Tools are also available for casing and tubular inspection. Surface data acquisition equipment and software displays this information real time allowing real time decisions to be made.
Production logging tools contain instruments that measure the physical properties of the well fluids such as temperature, pressure, capacitance and density. Combined with flow rate this information allows engineers to determine the relative volumes of oil, gas and water flowing in a well and the entry point into the oil well from the reservoir. This data is used to maximize hydrocarbon production and minimize water volume.
Casing inspection tools measure the wear and tear of casing and tubing within a well by using multi fingered callipers, ultrasonic and magnetic devices to determine casing or tubing thickness which may be impaired due to various factors such as corrosion, movement in the well bore or due to the build up of scale deposits. Identifying the state and cause of the casing or tubing condition enables decisions to be made about the type of remedial work needed to restore or maintain production capacity and prolong well life.
GPP supplied slickline services usually means a slick operation. State of the art equipment, skilled personnel and a strong safety attitude sets us apart. Slickline (often referred to as wireline) service entails the running and pulling of tools and equipment into and out of the wellbore using small diameter wireline which is mounted on a powered reel at the surface. This method of intervention allows essential well production operations and maintenance to be performed in a quick, efficient and economic manner. An increasingly wide range of slickline compatible downhole tools enables much different type of jobs to be performed such as those listed below.
Slickline units come in skid mounted or truck versions and different wire diameters are available depending on typical job depth and pull requirements. Units are available as either single or double drum versions. Double drums allow for either a spare wireline or two lines of different sizes.
