Dialog Wireline Services is the Premier Pipe Recovery in the Oil and Gas industry. Dialog also provides additional services and solutions for complicated and challenging well bore issues. Stuck pipe is one of the critical challenges in a well. It causes costly delays in drilling operations, workover AFE’s and increases downtime and production expense. These delays equate to lost productions and demands more or your resources with personnel to get your project back on track. The pipe recovery process starts with finding out the specific nature of the problem after consulting with your representative thus understanding all downhole conditions that exist. We then formulate a strategy determining what specific tools that need to be deployed that will best result in removing the pipe and BHA’s the specific problematic locations using a free point tool or stuck pipe log. Fishing tools are then deployed to extricate the pipe from the downhole fish. Dialog utilizes the freepoint tool to find the initial stuck point. A stuck pipe log can be deployed to find additional stuck points if deemed necessary. This data can be used to help determine the most time and cost-effective plan to free the stuck pipe. The stuck pipe log can determine where the pipe is free and where it is stuck. This log compliments the free point evaluation as the log tracks multiple stuck point locations versus only the shallowest point. The log data will help in deciding the best course of action to save you time and money in lost production and associated expenses. Dialog’s methods used in freeing stuck pipe include backing off and cutting. Backing off is a process where the threading is unscrewed at a predetermined wellbore depth using weight and torque. The cutting of tubulars can be done with chemical or explosive cutters. It is imperative to back off or cut where the pipe is free to ensure that tubulars and BHA’s are recovered. After the free pipe has been removed from wellbore, fishing tools can be deployed to retrieve the rest of the assembly. The recovery procedure can benefit you during Plugging and Abandoning (P & A) operations in removing installed pipe that’s no longer needed. The recovered tubulars can then be reused or sold by your company. The entire recovery process will be seamless, and you will have peace of mind knowing that Dialog Wireline Services has industry leading experience, knowledge and the most advanced tool to perform and provide a resolution for your company, thus saving your resources for other high value tasks.
The Dialog backoff service applies left-hand torque in the pipe while the string shot is detonated. The torque is applied at the neutral weight. The explosive percussion causes the joint to unscrew. Using the collar locator, the backoff can be verified before coming out of the hole.
Criteria that affect the string shot construction are:
The pipe size and weight, depth of stuck point and fluid weight are needed to determine the strength of the string shot and temperature is required to determine type of primacord and detonator. A string shot can be run in the annulus and backoff pipe from the outside.
The Dialog chemical cutter service is used commonly in wireline pipe recovery operations. It cuts through coiled tubing, tubing, casing, or drill pipe with a cut that does not have a flare and does not distort the pipe ID or OD. This service allows fishing operations to proceed without the need to mill the top of the fish. The cutter is designed to operate in extreme pressures and temperatures and does not leave any debris in the hole. Large diameter versions are available. The chemical cutter service does not require torque to be applied to the pipe which is particularly useful in applications where the pipe will turn freely but will not pull free.
The Dialog free point service uses an electromechanical tool designed to measure the amount of torque and/or stretch of a given length of tubing, coiled tubing, drill pipe or casing.
During drilling, completion, or workover operations, the pipe can become stuck in the borehole and the Free Point Tool identifies the stuck point so the pipe can be backed off or cut.
With tool sizes that vary from 11/16” to 1-11/16”, magnet, spring and motorize anchor options (Dog Tools) for wells with scale or Paraffin as well as high temperature versions. Dialog can free point all sizes of tubing, coiled tubing, drill pipe or casing.
Gyro/Whip stock Orientation Dialog can help get your drilling back on schedule due to the orientation of the whipstock when using the Gyro tool during sidetracking. This service insures that interference of MWD doesn’t occur and wellbore trajectory stays within your parameters.
Scientific Drilling has dedicated over 30 years to delivering precision gyro surveying – ensuring safe, efficient operations and optimal wellbore placement.
Dialog is one of a select few companies licensed by MCR Oil Tools to run their patented Radial cutting torch.
The Dialog stuck pipe log service uses a sonic measurement to provide an evaluation of a stuck pipe string. This service can be performed through drill pipe, casing or tubing to identify problem areas. Similar to conventional cement bond log measurement, high amplitude measurements indicate free pipe and low amplitude measurements indicate stuck pipe.
The stuck pipe log service is unique from the free point service, because the stuck pipe log service may be used to determine multiple stuck points throughout the well whereas the free point service can only identify the shallow most stuck point. The stuck pipe log service gives additional information that allows an informed decision to be made as to how to best proceed in the pipe recovery operation.
The 40 Arm Caliper is a mechanical downhole well logging tool. The primary function is to detect the deformation, bending, fracture, perforation and inner wall corrosion of casing with caliper fingers that are in close contact with the inner wall of the casing. Each caliper finger is connected to an independent non-contact displacement transducer that features small sizes, long service life, and high measurement accuracy. It measures pipe ID from 3.11” to 8.25”. After data is processed by the computer software, the diagram of borehole inner diameter and a 3-D image of the casing are created to intuitively demonstrate the damage details of downhole casing.
The 56 Arm Caliper is a mechanical downhole well logging tool. The primary function is to detect the deformation, bending, fracture, perforation and inner wall corrosion of casing with 56 caliper fingers that are in close contact with the inner wall of the casing. Each caliper finger is connected to an independent non-contact displacement transducer that features small sizes, long service life, and high measurement accuracy. It measures pipe ID from 3.94” to 9.625” and out to 13.625” with extended length fingers. After data is processed by the computer software, the diagram of borehole inner diameter and a 3-D image of the casing are created to intuitively demonstrate the damage details of downhole casing.
The Dialog Cement Evaluation Service is used evaluate the cement bond and the existence of hydraulic zone isolation. Depending on the applications, the cement evaluation service is performed with a single receiver bond tool, dual receiver bond tool or a radial bond tool. The single receiver tool utilizes a single transmitter and one receiver spaced at three feet. The dual receiver tool utilizes a single transmitter and two receivers spaced at three and five feet. The radial bond tool utilizes a single transmitter with radial receivers at two feet along with standard receivers spaced at three and five feet.
The X-Y caliper accurately measures two axes of the well bore allowing for an accurate cross-sectional area to be used in flow rate calculations, rather than a nominal diameter that may not be correct. Additionally, any gross defects within the wellbore can be identified. The tool provides data to calculate cement volumes needed to cement casing in place for isolation.
The four-arm device is designed to minimize the risk of jamming in side pockets and other well fittings, and the robust roller design minimizes wear while optional larger rollers ensure the optimum measurement accuracy.
