Acoustic / Rock Mechanics

When sonic pulses are introduced into the reservoir, the time taken to travel between fixed points can be measured. The rate at which sound travels is related to the properties of the formation rock and the fluids it contains. This information can be used for porosity estimation, fracture and lithology determination and correlation.

This data can be used in drilling applications (such as pore pressure determination, rock strength calculations, borehole stability analysis) and in geophysical applications (for example time-to-depth seismic correlation and AVO analysis).

Summary Summary Algeria: QBAT™ Multipole Sonic Sensor Replaces Wireline Run Sign in required
In this horizontal well in an Algerian gas field, the operator wanted to determine formation porosity and mechanical properties without using conventional neutron porosity tools with radioactive sources, because their use in the region is highly restricted.
Summary Summary Egypt, Mediterranean: Halliburton Delivers Vertical Well in Deepwater High-Pressure High-Temperature Environment and Saves Customer over US $1.8 Million Sign in required
Sperry Drilling was approached by an operator to drill a vertical well in the deepwater, high-pressure high-temperature environment of the Mediterranean Sea, where maximum temperature and pressure were approximately 390° F (199° C) and 20,000 psi.
Summary Summary Gulf of Mexico: QBAT™ Multipole Sonic Tool Eliminates Wireline Run to Identify Top of Cement in Deepwater Gulf of Mexico Sign in required
One operator challenged Sperry Drilling services to provide a means of identifying the top of cement in deepwater wells, without the costly and time-consuming wireline cement bond logging which greatly impedes deepwater drilling operations.
Summary Summary Oman: SOLAR Quad-Combo Saves 2-3 Days in HPHT wells Sign in required
In Oman, the operator of two high-temperature land gas wells wanted wireline-quality logs without the time and expense of wireline operations.
Summary Summary Mexico: Pemex optimizes a mature field well that is now producing three times more than nearby offset wells Sign in required
Pemex needed sonic data to calculate the mechanical properties of the reservoir in a mature field in Mexico to determine the best zones to fracture in the Jurassic Oxfordian sand formation.
Summary Summary USA, Alasaka: Sperry Drilling’s XBAT™ Azimuthal Sonic and Ultrasonic Logging-While-Drilling Service Help Stabilize Formation in Well Sign in required
In this well, drilled on a man-made island in the Beaufort Sea of Alaska, the operator’s primary objective was to log cement behind casing. Historically, well inclinations as high as 80 degrees in applications in this area create cementing challenges including micro-annulus, channeling, and fluid losses. In these high inclination wells, typical logging tools with two receiver arrays 180 degrees apart were unable to provide sufficient indication of the orientation of the azimuthal view of the casing and thus, no confirmation of where problems occurred.
Summary Summary Norway: Operator saves at least two days by running XCAL™ LWD caliper tool to determine hole quality and proper cement calculations Sign in required
To develop an offshore well in Norway, an operator needed to perform proper cement calculations, confirm that the hole was properly reamed, and evaluate packer placement for completion.
Summary Summary Nigeria: XBAT™ Azimuthal Sonic and Ultrasonic LWD Service Delivers Real-Time Shear and Compression Data to Help Stabilize Shale Formation in Deepwater Well Sign in required
An operator in Nigeria drilling a shale well in 3,827 feet (1,666 meters) of water encountered issues in determining the actual minimum mud weights needed to maintain stability of the formation.
Summary Summary Kazakhstan: First Complete Wireline Replacement in Kazakhstan Sign in required
Explore alternative means to acquire the well information while reducing rig time and eliminating multiple logging runs.
Summary Summary Angola: QBAT™ LWD Tool Delivers Reliable Compressional Sonic Data in Fast Pre-Salt Formation, Eliminating Need for Wireline Logging in High-Cost Deepwater Environment Sign in required
In up to 2,000 meters (6,560 feet) of water, offshore Angola, oil companies are exploring the potential of the pre-salt environment which overlays carbonates and sandstone but is primarily hard rock. Typically when logging such “fast” formations, where shear velocity is faster than the compressional velocity of the fluid in the borehole, timeconsuming wireline logging is needed because logging-while-drilling (LWD) sonic tools cannot always acquire reliable compressional sonic data.
Summary Summary Mexico: QBAT™ sensor helps Pemex to achieve sonic data in large 26 inch complicated soft-formation well Sign in required
In an exploratory well in the Akal field of Mexico, one of the main objectives of Pemex was to obtain reliable, high quality LWD information while drilling a 26-inch hole in a difficult soft formation.
Summary Summary Middle East: Operator Gathers Valuable Formation Features with the Only Service in Larger Hole Sizes Sign in required
Due to a lack of seismic data in a challenging remote location offshore in the Middle East, an operator was drilling several deepwater pilot holes for gas exploration in order to gain as much information as possible for well correlation and to gather insight into understanding the geological structure and depositional environment.
Summary Summary U.K. Offshore: Operator Saves Significant Rig Time by Gathering Complete Formation Evaluation Data in Real Time Sign in required
In an offshore U.K. well, an operator needed to obtain a complete formation evaluation (FE) data set to measure reservoir and overburden characteristics in a deviated well.
Summary Summary Oman: Operator Proves Cost Savings With LWD High-Resolution Imaging Service Sign in required
Borehole imaging is one of the most rapidly advancing technologies in wireline logging and logging while drilling (LWD). In an onshore horizontal well in Oman, an operator needed more details of the geology in the reservoir in order to gain a better understanding of the distribution of faults, natural fractures, borehole breakouts, and drilling-induced fractures along the well path.
Summary Summary Mexico: Operator Saves Time USD 7.5 Million in Deepwater Rig Time by Acquiring Crucial Formation Evaluation Data in Real Time Sign in required
An operator on a deepwater well had recently issued an internal mandate seeking opportunities to reduce the authorizations for expenditure (AFEs) associated with drilling its oil and gas exploration and development projects.
